2010 Camaro STS turbo

[Saoud]

A friend of mine wants me to tune his 2010 STS turbo camaro. He said it drove fine but suddenly all that it has been doing is it starts up just fine when cold.. and partialthrottles fine, But when the WOT is hit just near 3000 rpm it cuts down.

If you take the throttle slowly to wot. the turbos spool but the car runs soo damn rich and lots of smoke comes out. it runs 9.00 AFR.

I swapped out the plugs and comanded leaner fuel at wot. Same issue.

Tomorrow were testing the engines compression, I just need tips on this issue.

I'll post my tune later today so you guys could take a look at it.

Thanks.

Lets see a log..

here is the 2nd and third runs

MAF calibration hasn't been touched...that'll surely need changes on an STS setup. Can you log AFR?

Also, what method are you using to tune the VE coefficients? I assume you know that isn't part of the tune you can just throw some numbers into.

Injector Duty Cycle is 120% and it should be around 65%. The O2's on the wot blast where .950 mv that's @ an 11.5:1 wot AFR. What injectors do you have?

THe ones that were in the STS Turbo kit.

AFR Is not reaching 11.5:1 for your info its getting mad RICH.. going 9.5:1 afr

Thanks.
