Gizmo and Electronic Guide Phase 1: 8-21-06
NOTE: This guide is not complete. I still need to type up all the other EMS systems out there, boost controllers, turbo timers, fuel computers, ignition computers, etc. This does cover all the small things so far, including gauges. Stay tuned for the rest within the next 48 hours!
The gizmo guide! I’d like to explain why you get what you get, which kind to get, and how necessary it is. I can answer any more questions about the product I’ve spoke about, or even ones I happened to have “left out”.
TOPIC 1 – GAUGES:
Why do I want gauges? If you’re a guy, you always want to know what a girl is thinking (if you’re a girl, vice versa). Wouldn’t it be cool if you could have a gauge that told you if a girl was ticked off or totally in love with you? Think of that same theory on your motor. When you start modifying your car, or push it to it’s limits, you need to know what’s going on. There are MANY various gauges out there that will inform you of what’s going on with your motor, depending on what kind of mods you’ve done. Before I go into specifics, let’s talk about a differentiator in price, ease of installation, and accuracy. There are two major types of gauges out there, electrical and mechanical. It should be obvious which one is better. In case you don’t know, yes it’s electrical! They are far more accurate, easier to install, and can offer more features such as data logging or linking (connecting 2 or more gauges together to work with each other). The only downside is the cost. Typical electronic boost gauges will go for around $200 where most mechanical gauges cost about $50-60. It’s better to have a cheap gauge than to not have one at all. So if you’re putting a turbo or S/C on your car, you want to have a gauge, regardless of the type.
Boost gauges:
I started talking about this earlier but I will not go into much more detail. Boost gauges have some differences. Some read boost only. Some will read boost and vacuum. They will then be metered in either PSI or BAR. PSI stands for pounds per square inch. This is the more common way in the states to measure boost, because most people know what the limits are. BAR however is more common everywhere else, and on many high HP cars in the US. BAR stands for barometric pressure. 1 BAR equals about 14.7psi. On low boost cars, it’s not as common to use a boost gauge. Most BAR gauges read up to 2.5 BAR which is about 36.75PSI. If you’re only running 8PSI, you won’t ever hit one and this may be somewhat hard to distinguish while you are driving. My preference for low boost tCs is a PSI Boost/VAC gauge that reads up to 15PSI. You will use the bulk of the gauge and it may help you see the actual number you’re running more easily. I personally use a Stewart Warner gauge, but it’s not 100% accurate and I quickly found that out after I installed my Apexi RSM. Either way, a boost gauge should be the first on your list if you running any type of forced induction on your car. It’s a great reference to have, and it may keep you from blowing your motor one day.
A/F Gauges:
It’s hard to say which is the second most important gauge, but I still feel that the Air/Fuel gauge is a must. There are two main types of A/F gauges out there. One is narrow band, one is a wide band. What’s the “band” you ask? The band is actually in reference to voltage. A narrow band operates with a sensor in your exhaust, and it sends out a signal varying from 0-1 Volt. Narrowbands do not come with an o2 sensor because the rely on your stock narrow band (your primary o2 sensor) to give the signal. Some cars aren’t fortune enough to have a narrow band, so we use a wide band. A wide band is actually MUCH better to have than a narrow. Widebands, though more expensive, are MUCH more accurate in A/F readings. What makes them wide is the 0-5 volt reading the sensor samples with. Our OEM wideband is a single channel wideband, instead of the normal dual channel. This means that aftermarket wideband gauges can not use the OEM sensor. The end result is all of us needing to buy a full stand-alone wideband kit such as an AEM or Innovate. Both are great gauges. NGK makes a nice unit as well. I have the AEM gauge and love it. It comes with interchangeable rings and plates to match most of anyone’s gauge theme. You want this gauge to know what your air fuel ratio is reading. Run too lean and you may blow your motor. Run too rich, and you may be loosing unnecessary amounts of power, and waste unnecessary amounts of gas. The stock fuel trim for our tC is 14.7. This is entirely too lean for any FI setup, and results in super high EGTS (being discussed next). Optimal power for a turbo setup is a 12.7 AFR. Our cars weren’t meant for that kind of stress however, so a more safe tune of 11.5-12 is better. 10 is rich, 15 is lean. Now you know your numbers.
EGT – Exhaust Gas Temperature
EGT gauges are another great gauge to help with safe tuning and driving. Your engine runs HOT! It’s reported that we hit over 1600 degrees F on the highway. Consider that if you buy a gauge that maxes out at 1600. You may not get the entire read you need to know exactly what your motor is doing. 1600 isn’t great, but it’s been seen on more cars lately. STi’s run fairly high EGTs as well. Theoretically, you want low EGTs. Go too low, it’s a sign that you may not be generating enough power. Too high of EGTs could show signs of possible engine failure, or unnecessary wear on the motor. Typically when you pull ignition timing, you end up creating higher EGTs.
Oil Pressure
Though not the top 3 in my choice, it’s still one to consider. I STRONGLY suggest that you only run an electric oil pressure gauge. Do you really want a hot oil line running inside your seating compartment? The idea of an oil pressure gauge is monitor oil activity in your motor. If you break, damage, or drop an oil line or filter, you will lose significant amounts of oil pressure. Keeping your eye on this gauge on a race track may save you a motor in case an event like this was to happen. It will give you time to shut down the engine before it seizes, saving you a lot of money and downtime.
Oil Temperature
Running some serious amounts of boost? Have an oil cooler? What grade oil are you using? If you push your stock oil cooled system too hard on a turbo’d car, you may break down the viscosity of your oil to a point where it’s just not doing it’s job anymore. Having a gauge like this will again tell you to let off and diagnose the problem before it leads to something worse (turbo or engine failure). Many turbos only use oil as their source of cooling. Run over 15psi daily, and our stock cooler may not be enough. The oil will not lubricate things properly, causing an even greater hike in temperature, and your turbo seals will fail. Lets also not forget the piston rings failing as well!
Fuel Pressure – FP
Running a fuel pressure regulator? How about an inline pump? Fuel is combustible (obviously!). If you have a severed fuel line you may be leaking right into your hot engine bay! Safety is a big concern on the race track so if you’ve heavily modified your fuel system you may want to consider keeping your eye on fuel pressure so you know everything’s going where it’s supposed to.
There are many other gauges out there such as water temp, tranny temp, voltage, nitrous, etc. With proper research, you will easily find which gauges are necessary for your application. Gauges are a must and will help protect your investment.
TOPIC 2 – Electronic Meters:
There are so many to choose from out there it’s hard to begin. Electronic meters can serve many uses. The main benefit from most electronic meters is the ability to monitor and display more than one bit of information about the car at one time. It also takes up less space. The units do cost more, but they are very accurate, may be more cost effective, and they look cool!
Many of the following are copied from the information provided to us at Dezod in an effort to save time for this right up. This information is property of Dezod and is not to be disclosed without our authorization.
APEXI RSM-GP: Like the original, the new Rev/Speed Meter GP is a complete multi function measuring device designed to measure and monitor data such as vehicle speed, engine RPM, and elapsed times. However, the strength of the new unit lies in its differences. Probably the most obvious being its completely redesigned look. This new aesthetically pleasing model was crafted to match the likes of other highly popular A'PEX electronics such as the VAFC (VTEC Controller) and the AVCR (Boost Controller). The new screen utilizes the easy to read VFD (Vacuum Fluorescent Display) with built in light sensor used in many of A'PEX's line up. The new unit also delivers a host of new functions. Standard features include: Engine RPM, Vehicle Speed, Travel Distance, and Battery Voltage (All which can be displayed in real time graph mode, numerical mode, or analogue mode; 1-4 channels at a time.), Peak Hold, Replay (With 60 second playback.), Speed Limiter Cut, 0-100m/200m/400m times with trap speed, 0-100km/h/200km/h/300km/h times, Mid Range Acceleration (The user can preset any range of speed to measure.), Stop Watch functions, Best Time Memory, RPM Warning, Speed Warning, RPM and Speed Outputs (For external devices requiring an RPM or speed signal.), Tire Size Correction (For acceleration and timing accuracy.), and Vehicle weight input. One of the most exiting of the new features is the option to utilize the revolutionary A'PEX G-Sensor (Sold separately.). The G Sensor allows the unit to measure G forces in 4-way front/rear/left/right directions. This data can be plotted in a graph display to map acceleration characteristics and lateral G's on the race track, or used in an array of new features including: Highly accurate 100m/200m/400m times with trap speed and wheel-spin correction, Horse Power Calculation, and Loss Power Calculation. By taking advantage of the optional G Sensor, the user can produce extremely accurate power measurements Usually, when measuring 0-400m times through the speed sensor signal alone, the meter will end measurement too early (shorter distance) due to wheel-spin. Using the G Sensor modifies the speed sensor signal, compensating for wheel-spin and producing impeccably accurate acceleration times.
Greddy E-01 and Emanage controller:
GReddy's new super Multi-Display Controller is the E-01. Designed as data display / logger and e-manage programmer, the e-01 can provide 3channel data-logging and access to all the programming features provided with the latest e-manage support tool. The large LCD screen, with green elecro-illuminesant backlighting is easy to see. The data display can view 3 different data channels simultaneously inputted by the e-manage. The data can be logged up for 3hours on a SD card while also giving warning set points, and peak & hold values. (Some features require optional harness to be access)
Greddy Profec E-01 (Emanage controller with boost sensor)
GReddy's new super multi-tasker is the PRofec e-01. Designed as a combination: boost-controller, data display / logger and e-manage programmer, the e-01 can provide superior boost response, increased boost, warning meter functions, 3channel data-logging, and access to all the programming features provided with the latest e-manage support tool. Even when used as just a boost controller the e-01 has features to smooth out the boost curve. With both an Auto and Manual setting for both external and actuator style wastegates, the new PRofec can alter its new compact, high capacity solenoid valve via various RPM ranges if need be. The large LCD screen, with green elecro-illuminesant backlighting is easy to see. Other standard features includes two preset boost levels, a timed over-take boost and compatibility with our Remote Switching System. The data display can view 3 different data channels simultaneously; like Boost, RPM, or any other channel inputted by the emanage. The data can be logged up for 3hours on a SD card while also giving warning set points, and peak & hold values. (Some features require optional harness to be access)

G-Tech Pro SS and RR displays – Info taken from www.gtechpro.com
SS and RRs are both plug and play systems. The SS will display HP, TQ, 60’ time, 1/8th and ¼ mile time, 0-60, 0-100-0, RPM and shift lights, handling Gs, and will record up to 30 runs. The RR has the same features but adds Road Race and Auto-X data logging, Performance Analysis software, multi-car support, 2 hr data acquisition, PC download cable, AC adapter, and permanent mount.
Ok so you’ve read all that? Most of these monitors do the same thing. It’s slight differences in cosmetics and a few features here and there that set them apart. I run primarily Apexi electronics and I love them. They’re rock solid, small, and get the job done.
TOPIC 3 – MISC
There are LOTS of little tid-bit goodies out there than offer some unique upgrades. My favorite to date is the Spearco water injection system. It cools your car, it’s compact, it’s reliable, and makes your car last longer! What more could you want? The unit comes with everything you need except the water tank but it can be purchased separately. For really hot weather or prolonged abuse, this is a cool little mod to have.
Nitrous Express N-tercooler system:
Nitrous for turbos! No not the nitrous that slams you in your seat from the push of a button. No not the nitrous that can be catastrophic for your motor if you put too high of a shot in at once. It’s the same exact type of nitrous, but in a “topical version”. Not one ounce of nitrous will enter the engine. It is simply used as an ultimate cooling device for intercoolers. The best cars to use this are the STis/WRXs with top mounted intercoolers. Push a button and you can have nitrous blasted right onto your intercooler! This not only looks and sounds cool, it’s actually functional. Eliminate heat soak and get that extra edge at the track that could give you the win!
O2 Simulators:
Though I’ve NEVER seen one work on a tC, there are others out there that work wonders on other cars. EVOs and STis with cat-delete pipes can use this little gadget to eliminate a CEL that is only generated by lack of catalyst efficiency. It’s a cool little gadget that keeps the pesky CEL light available for more important matters. The o2 sim works by “fooling” your ECU. It modifies your secondary o2 readings to show your ECU that it still has a Catalytic converter, even though it doesn’t.
Greddy Multi-Switch system.
This little device uses connected sensors to control other devices by using pre-selecting switch points. It can use info from speed, RPM, boost, or any other analog signal. Use this to control fans, nitrous switches, fuel pumps, etc. It’s basically a clean way of using automated control, instead of having switches all over the place.
Fuel Pumps:
Need more fuel? How about just better atomized fuel? Cars running higher pressured fuel systems benefit from more even firing throughout all the cylinders, and better atomization of the fuel particles that mix with the intake charge. The end result is maximum performance with a lesser chance of detonation. Your two main options are in-tank and in-line. In-take pumps are full replacement and are harder to install. In-line pumps utilize your stock fuel pump and are easier to install. In-lines are only good to a certain extent of power. An in-tank is a better option if you plan on driving a track car, or something with high levels of boost. Walbro, Vortec, MSD, BBK, Blitz, HKS, etc all make fuel pumps for various car applications, including universal.
Magnetic Fuel Conditioner:
Although it’s not electronic, it’s still a gadget. This system spreads fuel particles apart using magnetism. The end result is better burn efficiency. Better efficiency means more power and more throttle response. Inazma HG is one of the products that does this.
TOPIC 4 – COMPUTER MANAGEMENT
Our favorite and most complex part! Let’s talk about how intelligent computers can alter every aspect of your car’s performance. The only limit is your budget here.
Sub-topic – Fuel and EMS systems (stand-alone and piggy back)
There are two types of EMS systems out there. The Stand-alone replaces your stock ECU with an aftermarket one, while a piggy-back utilizes your original. Piggy backs are less expensive, easier to setup, cost less, but are more limited. Full stand-alones require a professional tuner, much more money and patience, and the know-how of which to get. The stand-alone has much greater potential if you know what you’re doing.
Piggy-backs:
GReddy Emanage Blue:One of the most common piggy back computers on the market today. It can control fuel and ignition, provided you buy all the harnesses for it. It works by modifying the MAF or MAP signal that the ECU sees. This is a nice simple way to tune things. For ignition, it simply intercepts the original ignition signal and delays or advances it where it’s told to do so. Even on MAF based cars, you can still tune by MAP if you purchase the Greddy Pressure sensor. This sensor is rated for about 45psi so I don’t think you’d ever need to worry about upgrading that unit. Use the pressure sensor if you’re running any type of forced induction. This makes boost transition much smoother, and allows you to modify the boost level without having to re-tune it every time. To tune the system, you can use an E-01, Profec E-01, or a Laptop PC if you purchase the support tool software. I’d use the support tool/laptop option because you can adjust every parameter of the unit with ease. The only downside to the Greddy EMS is the way it controls your engine. This may seem as a major flaw, but for mild boost this is still a great unit for the money. The system ONLY modifies MAF or MAP signals. The new cars are smart out there. Our tC is one of them. Our ECU always reads off of the primary o2 sensor to determine the AF values, in which it adjusts as necessary. That being said, the Emanage has no control over partial throttle tuning! The ECU simply overrides the signal and brings it back to the stock tune. You do have full control over WOT, which is where you make your peak boost/stress anyway. This is a good unit for the money, but still not the best option for our cars. This is why we’re developing our own EMS.
The gizmo guide! I’d like to explain why you get what you get, which kind to get, and how necessary it is. I can answer any more questions about the product I’ve spoke about, or even ones I happened to have “left out”.
TOPIC 1 – GAUGES:
Why do I want gauges? If you’re a guy, you always want to know what a girl is thinking (if you’re a girl, vice versa).

By taking advantage of the optional G Sensor, the user can produce extremely accurate power measurements Usually, when measuring 0-400m times through the speed sensor signal alone, the meter will end measurement too early (shorter distance) due to wheel-spin. Using the G Sensor modifies the speed sensor signal, compensating for wheel-spin and producing impeccably accurate acceleration times.

Ok so you’ve read all that? Most of these monitors do the same thing. It’s slight differences in cosmetics and a few features here and there that set them apart. I run primarily Apexi electronics and I love them. They’re rock solid, small, and get the job done.
TOPIC 3 – MISC
There are LOTS of little tid-bit goodies out there than offer some unique upgrades. My favorite to date is the Spearco water injection system. It cools your car, it’s compact, it’s reliable, and makes your car last longer! What more could you want? The unit comes with everything you need except the water tank but it can be purchased separately. For really hot weather or prolonged abuse, this is a cool little mod to have.
Nitrous Express N-tercooler system:
Nitrous for turbos! No not the nitrous that slams you in your seat from the push of a button. No not the nitrous that can be catastrophic for your motor if you put too high of a shot in at once. It’s the same exact type of nitrous, but in a “topical version”. Not one ounce of nitrous will enter the engine. It is simply used as an ultimate cooling device for intercoolers. The best cars to use this are the STis/WRXs with top mounted intercoolers. Push a button and you can have nitrous blasted right onto your intercooler! This not only looks and sounds cool, it’s actually functional. Eliminate heat soak and get that extra edge at the track that could give you the win!
O2 Simulators:
Though I’ve NEVER seen one work on a tC, there are others out there that work wonders on other cars. EVOs and STis with cat-delete pipes can use this little gadget to eliminate a CEL that is only generated by lack of catalyst efficiency. It’s a cool little gadget that keeps the pesky CEL light available for more important matters. The o2 sim works by “fooling” your ECU. It modifies your secondary o2 readings to show your ECU that it still has a Catalytic converter, even though it doesn’t.
Greddy Multi-Switch system.
This little device uses connected sensors to control other devices by using pre-selecting switch points. It can use info from speed, RPM, boost, or any other analog signal. Use this to control fans, nitrous switches, fuel pumps, etc. It’s basically a clean way of using automated control, instead of having switches all over the place.
Fuel Pumps:
Need more fuel? How about just better atomized fuel? Cars running higher pressured fuel systems benefit from more even firing throughout all the cylinders, and better atomization of the fuel particles that mix with the intake charge. The end result is maximum performance with a lesser chance of detonation. Your two main options are in-tank and in-line. In-take pumps are full replacement and are harder to install. In-line pumps utilize your stock fuel pump and are easier to install. In-lines are only good to a certain extent of power. An in-tank is a better option if you plan on driving a track car, or something with high levels of boost. Walbro, Vortec, MSD, BBK, Blitz, HKS, etc all make fuel pumps for various car applications, including universal.
Magnetic Fuel Conditioner:
Although it’s not electronic, it’s still a gadget. This system spreads fuel particles apart using magnetism. The end result is better burn efficiency. Better efficiency means more power and more throttle response. Inazma HG is one of the products that does this.
TOPIC 4 – COMPUTER MANAGEMENT
Our favorite and most complex part! Let’s talk about how intelligent computers can alter every aspect of your car’s performance. The only limit is your budget here.
Sub-topic – Fuel and EMS systems (stand-alone and piggy back)
There are two types of EMS systems out there. The Stand-alone replaces your stock ECU with an aftermarket one, while a piggy-back utilizes your original. Piggy backs are less expensive, easier to setup, cost less, but are more limited. Full stand-alones require a professional tuner, much more money and patience, and the know-how of which to get. The stand-alone has much greater potential if you know what you’re doing.
Piggy-backs:
GReddy Emanage Blue:One of the most common piggy back computers on the market today. It can control fuel and ignition, provided you buy all the harnesses for it. It works by modifying the MAF or MAP signal that the ECU sees. This is a nice simple way to tune things. For ignition, it simply intercepts the original ignition signal and delays or advances it where it’s told to do so. Even on MAF based cars, you can still tune by MAP if you purchase the Greddy Pressure sensor. This sensor is rated for about 45psi so I don’t think you’d ever need to worry about upgrading that unit. Use the pressure sensor if you’re running any type of forced induction. This makes boost transition much smoother, and allows you to modify the boost level without having to re-tune it every time. To tune the system, you can use an E-01, Profec E-01, or a Laptop PC if you purchase the support tool software. I’d use the support tool/laptop option because you can adjust every parameter of the unit with ease. The only downside to the Greddy EMS is the way it controls your engine. This may seem as a major flaw, but for mild boost this is still a great unit for the money. The system ONLY modifies MAF or MAP signals. The new cars are smart out there. Our tC is one of them. Our ECU always reads off of the primary o2 sensor to determine the AF values, in which it adjusts as necessary. That being said, the Emanage has no control over partial throttle tuning! The ECU simply overrides the signal and brings it back to the stock tune. You do have full control over WOT, which is where you make your peak boost/stress anyway. This is a good unit for the money, but still not the best option for our cars. This is why we’re developing our own EMS.

There's MUCH MUCH MUCH more to come guys. I may even make a large file for the website as a basic guide of some sort.
I still need to get into boost, fuel, and ignition managament. Who knows what I'll hit from there.

I stopped typing more abotu this stuff because mods kept taking all my info threads off the stickies. If I spend 5-6 hours typing stuff, and it's gone in a couple weeks, it's hard to keep making myself post more and more.
It was stickied for about a week or 2, but that was it after that.
