So Kindle racing what kinda of engine management are you guys running on your car. I hear the SS/SC is pretty locked up via the ECU, how do you get around that with the turbo setup?

 

All's i can say is i have finally done the engine management system on to the Chevy Cavalier a few days ago. and was able to produce from an Ecotec 2.2 140 hp to over 180 hp.......including the fuel enjections,....i`m not too sure with the ECU on the cobalt would beable to kick in horsepower range, but since its chevy... it should shoot over 30 hp with no problems.

see ya.......



Dude....

 

Alter the parameters the ECU sees.

I use a TurboXS D-Tec which modifies the MAP voltage the ECU sees. I use this for fine tuning. I also have a return fuel line setup with a Rising Rate Fuel Pressure Regulator. I use this for coarse tuning. The two of these together work really well to tune the fuel.

I use an MSD Programmable DIS-2 for the ignition. Unfortunately there's not alot it can do since it can't advance the timing, just retard it. But it does have alot of features I can use at the dragstrip to help control wheelspin. It has a burn-out rev limiter as well as a launch limiter. It has gear dependent timing retard, a launch timing retart and I can use it to control the RPM range of nitrous when I add it later. It also has 3 timing retard maps that I can turn on or off with the flip of a switch (one of these will be used in conjunction with the nitrous setup lateron); Also these maps are cumulative, so I effectively have 8 different timing maps available.

On my race car, I went with a full standalone... something I'd definitely not recommend for a daily driven street car.

 

Well the folks at PSI-FI have mentioned a lot of issues with a piggy back on the Red Line ECU because it's not enough to just trick the car into giving it more fuel, it's keeping all the sensor inputs happy so you doing go into limp mode. The phase 5 cobalt can't be running on the stock ecu setup, so either GM is planning on helping use out or what?

 

We use an AEM box; I don't think they have released it to the public yet though. You might try and give them a call to see where exactly they stand on release, etc., they usually do not release something until they have 100% of the bugs worked out.
