Well i didn't get the hydramist but the harness will make it easier for switching it on, as well as it makes it so you can toggle between 2 different maps without having the laptop hooked up. Also can control nitrous, and something else i forgot all the details. Theres not much of a DIY its well put together with a detailed list/pictures on which pins to plug into the hydra, Only one issue and the pins to plug into the factory Cruise Control Clutch Switch (CCCS) the connectors are to big you'll have to cut them off and splice it in. NO biggy. Everything else is easy plug and play, and he also set the map up for you so you can have launch control as soon as plugged in. He did say we are going to have to play around with it to get it lower then 4700rpms but i will tell you with sticky tires and boost per-gear i don't see why that high is a problem. With a 2step you can focus on slipping the clutch and nothing else. It is the 2nd best thing i have bought since the hydra. I called and talked to Phil and he said everyone can call/e-mail him to buy them. He will tech support anything bought from him 100%. Also i got off the phone with Andrew at hydra and he said you can buy a boost solinode kit from any auth. dealer so you can set up boost per-gear which will also help with spool up. I think he said that would cost right around $120 so i should be ordering very soon from phil so he can help setup the map for it.

 

my apexi boost controller... might be going on saleeeeeeeeeeeeeeeee!!!!

 

NICE!

 

very nice, i didnt know that hydra has that much acccessories to intergate with the ems, they should put all those details together so hydra users will know the capabilities of the ems..

 

You better...

 

ok here's what i found out about the 1 year warranty.. Warranty starts after the unit has been in the position of the hydra dealer, not after the end user purchased the product. I bought the unit June 08 and now I have my unit checked and was told it the warranty is expiring this week! That part sucks, they shouldnt have hydra dealers then and just have all units ordered directly from hydraems.. that way everyone will have a fresh warranty. The good part though is that they warranty hardware for 2 years

 

now here's what I found on my relay,



the red wire wasnt connected to anything, its supposed to be tapped to 12v constant on power! i've been running low voltage on my hydra the whole time.. anybody knows a good place to tap this?

props to awesome hydra customer support

 

i'll have to check my car...

I wonder if mine has been running on low voltage too.....

 

I just checked mine. I was worried there for a second, lol.

The wires coming off of my relay, are actually already wired into the harness, for the appropriate 12v constant and ground.

*phew*

 

From what the HydraEMS team told me, the harness didn't provide enough power, so they had that wire to be put direct to the battery (or as best you can).

 

hmmm...

Thats odd... mine came like that when I bought it w/ my turbo kit.....

I'm gonna have to ask yamaha how his looks like. Because we have the same kit.

 

Ok another question... If the voltage is low, what kinda problems will it cause?

 

hey ipp i take it you havnt gotten tuned

 

Not really, lol.

I pinpointed a possible problem.

I have PE 800cc injectors, at 14 volts the lag is 1.6 ms

I compared it to others injectors of similar size (800cc), and their lag time is 1ms or less. So basically they open/closer faster than mine.

I got my car to idle, but when I lower the pulse width, it dies if its anything leaner than 12afr.

I wanted to change the injector latency map, so it can be close to what my injectors actually are. But the latency map only goes up to 1.2ms

So that doesn't help.

The only other possibility I see, is to go with low impedance injectors which usually have much lower lag.

I'm probably going to go with RC Engineering 750cc low impedance, denso style injectors. The lag time I think is something like 0.8ms at 14volts. Which is super faster than mine.

So with those I should be able to idle a lot better. So i'm gonna purchase those next paycheck, and then take it to get tuned.

N/A cars turned Turbo cars are a lot of work >.< !!!

 

I am working on getting some 1000cc injectors in as well that are high impedence drop ins and offer a faster reaction time. I do have that problem with idle on the 800's every once in a while although adjusting the latency time and targeting 13:1 usually solves the problem it's still not optimal. I need bigger ones anyway for later on.

 

did you put an inline fuse on that wire? im gonna use a 30 amp on mine, just wondering what the actual power draw of the hydra unit.. anyone got an idea?

 

how do you guys know the lag time of the injectors? i wonder what's mine on my denso 550s

 

Your injectors aren't so big. So I would imagine the lag time shouldn't be bad at all.

I hooked up the laptop and checked out the voltage on the hydra, with the key in the on position (and engine off).

The voltage is about 11.9-12.0

Once the car is on, the voltage sits at about 13.2-13.3

I forgot to see what the voltage is, when i'm cranking, but i'll take a look at it later.

I'm using an optima yellow top.

Oh and I found the lag on yours ace83.

Denso 550cc
2 ohm Injectors
1.24ms @ 10Volts
1.04ms @ 11Volts
0.87ms @ 12Volts
0.75ms @ 13Volts <== So assuming our voltage at idle is the same. Your injectors are about twice as fast mine =(
0.64ms @ 14Volts
0.55ms @ 15Volts

I'm pretty sure you can use these values under the injector response map. Buttttttt, it'll throw the tune off, so it'll require a retune.

But your car runs fine anyway, so I think you should just leave that map as it is, and not mess with it.

 

good infos there, where did you get those?

 

My 2 step launch control should be here on thursday or friday. Same thing that Mike has. I was told by Phil at Element Tuning that will do "no lift "shifting as well. Which he says his STI's see .5 sec or faster times with the "no lift" alone. So 2 step plus no lift should be fun

I'll put up a video as soon as I get it on.
