    Default Tries to die when put in reverse

    What table in EFI Live would I need to look at for airflow when shifting from Park to Reverse?
    My Tahoe will sit and sputter and gasp and drop rpms to 400 or so unless I give the gas pedal a stab. I thought it was my previous cam with all the overlap but, now i have 0 overlap and still have the issue. I have a stock 6L tune to compare my tune to but I dont know the tables I should look at.
    Thanks,
    Chris

    Welcome to the forum Slowhoe. Are the trans components still stock?

    Take a look at B4338 B4339 and maybe B4522, though Im not sure if the last one will work for you. I had the same problem. I set my idle at 690rpm. It idles nicely there, but doesnt leave much room for error. I messed with these and it helped.

    I went through my tune and set ALL the tables from the "Idle" folder back to a stock 2002 LQ4. Some of my stuff was pretty out of whack. What would I also need to adjust away from stock for my cam?
    I have the Lingenfelter GT2-3. Specs are 207/220 .571/.578 118.5lsa. I figure with the lsa wider than stock (I think stock is 117) the only thing I should have to account for is the higher lift.
    So what tables do you guys mess with for a cam and why?

    Usually {B4307} will get your idle back in line. The RAFIG and RAFPN PID's are used to obtain the values you need to adjust {B4307}.

    Are you familiar with setting up Map's in the Scan tool?

    Yeah that cam is tame. Desired Airflow as mentioned will do 90% of it.

    I'm barely familar with how to use EFI in general. I have an Innovate wide band that I still have yet to link up to EFI. I have read about RAFIG before but I still dont understand it too much. I was also told that when you hook up your cable to the car/truck there is a button you can hit to validate what PIDs can be read. Anybody know if thats true? Is there a tutorial on setting up Maps?

    To validate PIDs, hit Shift+F2 when you connect to the scan tool. You should only have to do it one time per vehicle that you connect to.
