Found this the other night searching the web and decided to follow up on.

http://www.jetchip.com/V_FORCE_PLUS.asp

Although it does not say that it will work specifically on the xD, it does say that it will work on all 08 Toyota 4 cylinder's. I gave Jet a call today to ask some questions and was told that it would work on the xD and the website was not updated. I was told that with the V-Force plus you can expect gains of 10 WHP and 12 Torque on a stock motor and more with intake and exhaust. Not too bad and allows you to monitor some other cool information.

 

Interesting, should post this in the aftermarket support sticky in the general discussion area

 

hmm interesting, I guess the ECU has been cracked. Shame this is only for stock cars.

 

Looks like this will work on all the original scion models too-never heard of anyone using one though.

 

$350.00, could definitely be worth it if those gains are true on an xD... ive always been very leary of chips such as this.

 

If its the same company which it might be jet performance used to be pretty large in parts for trucks (used when i had my lowrider) for tranny shift kits programers and with the price and that it looks to be more than just a resistor it makes me curious would really want to see one of these tested

 

Yea I know a lot of muscle heads I mean muscle cars use them So they're not really a no name brand. Its just a matter of whether it truly does work on the car.

 

I had a Jet Performance reflash my ECU on the Nissan Frontier and could tell a huge difference. Jet had be around for quite some time and does have a proven track record. I am more interested in the install side. It sounds like it is not a plug and play unit, that you have to tap into a 3 wires.

 

A general "chip" for all Toyota 4-cylinders... sounds fishy to me.

 

Yeap... the "General" part doesn't sound right.

A 1NZ, 1ZZ, 2ZZ, 2ZR al diiferent 4 cyl Toyota engines. Every one of them diffrent from the other. For a 10hp gain on a N/A car with out custom tuning... hmmm don't think so.

Will like to see some one trying it tough!

If the told you it WILL work on an xD it means they "Must' have test it right? And a Dynosheet should be available right?

 

Although Toyota does have a verity of different motors, they are all run by the same software with very similar parameters. Auto Manufactures will de-tune their cars for a verity for different reasons and a couple ways to do that is to A) retard the timing B) have the computer control the throttle plate at WOT and C) run the AFR fat. So by simply advancing the time slightly, leaning out the AFR and have the throttle body wide open at a WOT, it would not be that hard to pick up 10 WHP. This is what all other "chips or performance modules" do. Its like saying that it sounds fishy when HyperTech of Superchips claims that their programmer works on all Ford V8's. Listen, I am not trying to sell this to anyone, but do know a "little" about tuning. On the other hand let me a say that I am somewhat skeptical. I will heading to SEMA next week and plan on talking more with Jet Performance regarding this product.

 

well, considering that they offer one unit that works on all scion tc's from 2005-2008, sharing the same part number, i'm going to say no, they are lying, because the 2005-2006 are different from the 2007-2008 engines, so they are probably selling a big pack of lies.

if somebody wants to risk their money and buy one and dyno their car, that'd be great, but i put on on my 95 ford explorer, and got...nothing. it isn't worth it, the thing looked like a gameboy game cartridge that you pop onto your ecu. it doesn't work.

 

True. All manufacturers slightly 'detune' the vehicles for various reasons but each engine will still require a specific adjustment to gain power... Sensor input voltages will be similar, but have different ranges. That's why this is limited to 4-cyl engines. The ranges are determined by a few factors, including power range and estimated air intake rate.

It's like saying someone supercharges their car and dyno-tunes it w/ a Apex'i S-AFC. Now you supercharge a different car and buy the used S-AFC and install it. Will the same settings work? Very unlikely.

All the chips end up doing is changing the input from the sensor to reflect a value which causes the computer to adjust to "add more power" (aka fuel) to the mix. It's a generic part because it's simply tweaking a sensor versus actually modifying the ECU's control.

Money is better spent on getting a piggyback controller (or full management if you're modded beyond belief) and spending some cash to have it dyno tuned.

On a sidenote, I thinkt it was JET that made a chip that actually works in the Tundra... but it was specific for the truck. I read about it a little bit at Tundra Solutions... but don't remember the exact outcome.

Toyota, Honda and Nissan are working on creating a proprietary operating system for their ECUs. It will make tuning either much easier or much harder. For Toyota, very likely to be much harder.

 

colosky, let us know if you find out anything at SEMA...

 

So after talking to Jet at SEMA, they have two options for us. 1) the V-Force Plus- a microprocessor that intercepts signals from certain sensors and alters them going into the ECU as well as providing in cab info on the motor. I was told that typical gains on a Toyota 4 cylinder motor is about 8 WHP on a stock motor and about 10 WHP on a slightly modified motor (intake/ exhaust). The install does require you to tap into a few wires and would probable not be very dealer friendly (i.e not PNP). Option #2 is their re-flash. This requires you to pull out the ECU and mail it to Jet. Jet will then re-flash it with a tune that is specific to the mods you have already done. This option works the best when it is the last thing you plan on doing since it is a specific tune. With the re-flash I was told you can expect 12 WHP stock and 14-15 WHP with intake and exhaust. I would venture to bet that with the Danatek manifold you might get even more. The nice thing about the re-flash is that the dealer will never know that it has been done and if you mail it back to Jet, they will return it back to stock for free within I think the first two years. I had my ECU re-flashed by Jet on my 05 Nissan Frontier 4.0L and could tell a huge difference. A little under 2 years later I decided to put on an aftermarket supercharger and it require that my ECU be stock. I mail it back and they did it for free. This is probably the route that I will take with xD. My only plans are CAI, intake manifold, exhaust and the re-flash.

 

Sounds promising!

Are this 2 options new additions to their portfolio? I'm wondering since I never heard about this before for any other of 4 cyl modern Toyotas. ( Scion TC,xB,xA, Yaris...)

Did they mention if they had actually done a re-flash on an xD yet?

There is something that still doesn't add up for me. There are other companies that offer this kind of services for other cars like the turbo Volkswagen's, Audi's, or the Dastek Unichip for a lot other models.

Those companies in order to offer custom tunes based on the mods you have on your car, actually need a car and all the most popular bolt on mods and combinations so they can set the all the different tunes for any given mod you have.

In other words, how can they offer a re-flash for a Scion xD equipped let's say with a CAI, Intake Manifold and a custom exhaust.... unless they already had and actual xD
with all those mods to make the new base tune???

Can some one enlighten me!

I will be really interested on a tune to make the most out of all the bolt ons.


I have a hefty goal... before pursuing any kind of forced induction... I would like a 150whp NA 2ZR-FE and I believe that it will be really hard to get there with out some sort of tuning.

 

There is someone making an intake manifold (dynatek?) for the xD-says it gets it to 145hp. They have the dyno runs to prove it too.

Can't remember where I read that though.

 

I wonder for us socal people if we coould just bring our car down to have the reflash done. I believe they are local. I would deffinatly be down for that.

 

Be a pioneer! Go for it.

 

Well I sent them an email, we'll see. That would be awesome for a reflash. If our factory ecu is reflashed that must mean they cracked our ecu finally. Piggybacks have had the problem where in closed loop they wouldn't be adjusting anything only in WOT. If JET really offers a reflash I see this becomming very popular. If this is possible I will deffinatly bring my car down, although I am unsure how willing I am to go dyno and all that. The price of the reflash+dynoing before and after is just not worth 14hp in my eyes. I'd rather use that towards a turbo or amps+sub. I like the idea of a reflash for simplicity, and that it should be readjusting while in closed loop+open loop being a reflash.
