    Hey Thanks Jason,
    Lowest cell I could usually hit on MAF was 3600. I noticed in the Base Airflow you created was 91 lb/hr, which is really close to the 90 lb/hr I got in the 3600 cell. Looks...

    Cammed 357 Idling Issues E38

    Hey all,
    I have been through Big Mike's thread on idle tuning and a few others. I'm still getting RPM error as high as 100+ :(
    I've brought my idle spark table up by 4 degrees.. wasn't sure if I...

    A 20% increase worked. ��
    Now if only I could get it to idle below 1100rpm ��
  5. Dialing in low RPM airflow, in MAF and SD, truck wont idle now.

    I tried to find a thread on this.. Couldnt find anyone else with the same issue.

    I got closer to getting my MAF and SD tunes both near lambda.. I always multiply by half..

    My cells in the idle...

    I didnt know you had nitrous..but I was thinking you could use the same method to cause backfires at the push of a button. The switch and resistor basically tricks your engine into thinking it's -40?...

    Double both the "Percent Max" settings till you get it tuned.

    I'm learning we may not be able to trust the wideband sensors.. Both my narrowbands are in agreement, but while they read rich, the WB is reading lean.

    I'm guessing if you plugged the valve in the oil pan, you've deleted DOD? Might be possible that the DOD/AFM towers on top need plugged with 1/4 rivets.

    Might also log Misfires on all 8 cylinders.. That could help determine if any injectors are leaking, plug is fouled, or if there is a vacuum leak on that side.

    That data plugged right in... still having issues with O2 sensors reading richer than the wideband, but that is probably best for another thread if I can't find the answer.
