Default Need Suggestions Please.

I have a 383 with a T-trim, no maf. I upped all the tables that had to do with the p1514 code, and don't trigger that anymore. I have also reduced ifr and ve by 30%. At about 6400 rpm the car still shuts down with no codes. I would like to know which pid in efilive to log so I can see dynamic airflow and also was wondering if someone could post a tune that I may look at and see if I am missing something. Maybe my ve is way off or something. It doesn't need to be the same combo, just something blown so I can see the ve. Thanks for any help.

i believe you are looking for "calculated air flow rate" hit f8 in the scan tool go to air in the system drop down menu here is my 346 with a D1 at 8 psi. i live in denver so the ve will be 20% lower due to the low baro 83kpa sea level is 102-103kpa have you tried the auto ve

Yeah, I have been having this trouble since I went speed density and did the auto ve. Thanks for the tune, but I have efilive and did not mention that. Thanks again.

If this is in your 97 C5, id highly suggest yuo swap to the 99-02 PCM then you can use EFI Live custom operating system number 5 and go to a speed density 2 bar map tune, youll love it.

Click the link in my sig for a how-to demonstration from when we swapped the PCM in my 97 C5

It is a 97 and I have seen your example. I have been seriously considering it.
