I put my psi-fi kit on last night it took about 3 1/2 hours to do. when i finished i took it for a spin and had cel on. when i got on it it detonated so i brought it to a friends house he has a code reader when i erased the cel i took it out again and it still did it but very little. i brought it back home and took it out again and it stopped completly. i put some octane booster in it and that helped. other than that the car is a completly different car it pulls much harder than before. i thought our first gear was short before, man i cant give it wide open throttle it just breaks lose in first.

 

What was the CEL code?

 

dont know he reset it and when he went to print it out it would not for some reason but it has not come on since

 

let us no when you get it dynoed. Good luck sounds like a nice set up.

Mine ran like crap after I first installed the kit... took a good 100 miles before it was just right.. Has been great ever since... I never did get a CEL or any codes... I would double/triple/or quadruple check your wiring just to be for sure... also check all you vacuum lines/hoses.... But anyways... Congrats !! I love my Psi Fi kit !

 

my cel is back on i have no idea whats going on.

 

what exactly does the psi-fi kit do? is it just a piggyback system or what?

 

Computer Bypass and allows to retard the timing slightly so you can run higher boost with a smaller pulley, it gives the computer accurate readings on how to run with the correct air/fuel for the setup.

 

Just one more reson to wait for the GM Stage kits.

And a piggy back doesn't give the ECM accurate readings it tricks it into thinking certain perameters are different. In doing so maximum values can be reached and throw trouble codes also.

The GM kits are worth the wait, bigger gains, No CEL and warranty are worth it.

 

codyss you dont have a Psi Fi kit and have probably never driven or rode in a car with one. You bash it all the time but have ZERO experience with one Im sure. But I do notice everytime you have a chance you say its crap. All he has done is installed it incorrectly. Ive been running mine since it was release and have had no CEL. So have many other people.

 

What makes you think GM will warranty there stage kits? DCX doesn't warranty the SRT-4 kits.

 

"The word on the street" is that they will be under warranty. But we won't know for sure until an official release.

 

I dont think he really means because of warranty but because that they will include an actual pcm reflash instead of having to use a piggyback.

 

I don't need to see or ride in a PsiFi equipped SS to tell you the GM kit will be better. Anyone with anyone common sense could make that call. Just because it is the first one out there means nothing.

The pure fact that it is a piggy back unit makes it inferior.

 

ok u said the cel is back on, go get it read and tell us the code

 

I recommend all who plan to modify their Cobalts to get a code reader.

 

His code is for High Intake Air Temp... Im working with him right now to correct...

Although ive read on other forums of atleast 1 person getting the same code when the weather is very cold..... but maxss is in LA.... this other person is in StLouis.... Theres a good 10-20F diff in the lows at night...

 

I am the one getting it in St. louis. The code is p0113 High Iat 1 voltage. I only get it when the temp is below 50 degress. Psi Fi is working on it I am sure they will come up with a solution.

 

or get the Interceptor gage unit. Works great for rading/clearing DTCs (besides the other useful engine data)

I was thinking someone might purchase the steering column mounted Redline boost gage and ladder tach cept put the Interceptor in there. (or switch em around) The ladder tach should work fine IMO.
I havnt seen any DUAL gage pillars yet for the Cobalt. Any out there??
