Anyone Could help me adjusting the AFR Corvette C6 ls2

[Alfdhalah]

Hey guys,
I just tuned my car a week ago and it was running good my AFR was at 11.5, i just noticed yesterday that my car is having a fuel cuts on 2500rpm to 3000rpm. I scanned it with my LM-2 Wide band and I found that my AFR stands at 13.something . anyone could help me adjusting the AFR ? And also it happens every time i tune the car after a week or so the AFR keeps changing. The car Is procharged D1

And I'm going to swap a cam this weekend which table should adjust ?
Thanks

Did you "tune" it by adjusting the PE table to get your desired AFR, or did you actually put in good complete injector data, fix the MAF curve, and VE tables?

If you did the former, the car is only "tuned" to a single weather condition on a single day, at a single engine and air temp. This almost guarantees trouble later.

If you did the latter, it should stay consistent even as the weather changes unless you have a mechanical issue.

Thanks Greg, I think my PE table is messed out , What is the PE calculation ? and what should my stoic be at ? I'll upload the tune tomorrow or by the end of this week if you guys could help me out adjusting my tune I will really appreciate that. I'm a new HP tuner user looking around to get help .
Thanks all

Nothing solid yet. I keep getting random single requests, but nothing serious enough to pay for flights, hotel, time, etc... It's really tough to convince me to leave Michigan right in the middle of waterskiing and wakeboard season too.

Click on the "Go Advanced" at the bottom of the this page under "Quick Reply"

Then scroll down to "Additional Options"

Then under "Attach Files" and find the tune using the "Manage Attachments" double click the tune files and that should do it.

No i Did not, should i adjust just the PE table ?

[vette_c6]

u should
your commanding less then 11.0
and your having 11.5 AFR
means you have a HUGE AFR error
