    You shouldn't need to change the spark tables to get rid of the hanging rev on coast down. This can be done via the cracker/follower tables: multiply follower decay (gear) X 4, zero out follower...

    You're right, the vette multipliers changed a lot also, that one was a bad example. The fbody multipliers are the same though, 98-00 vs 01-02, but the max airflow values are different by 2X. I've...

    e-brake is applied, as well as regular brake, and definitely at operating temp (I wouldn't rev it that high until oil is fully at temp). Any other suggestions appreciated.

    I noticed in a recent scan that in the middle of an extended idling period, the commanded afr suddenly went lean (15.75) and o2's pegged low for 7 seconds, then went rich (13.98) and o2's went high...

    car OS: 2000 fbody
    computer OS: windows XP

    In the editor, open IAT Spark table, and also open a compare file for the same year. Look at the main...

    logging: should ask to save before exit

    At the end of a logging session, if you exit without saving the data first, it should ask you if you want to save before actually exiting. Come on! this is just obvious UI stuff, I've never used...

    Well I guess no-one knows, but now I came across some posts saying burst knock does not show up as KR, it just pulls timing... is that right? So looking at BK won't help solve a KR problem?
