    So with my combo.

    416ci - 226/242@116
    FDFI2650 with 102mm
    3200 stall
    Target idle rpm = 850 in P/N & In-gear then 875 from 8kph & above.
    Idle Spark set to 14 degree's

    At the moment I'm at 30 for min & 90 for max & it's that good i don't think i'll bother changing it from here. i did initially try a 60-90 mix but it would cruise with no throttle because it wasn't dipping into closed throttle or coast down spark.

    It seem's to have mellowed the idle trimming out big time & corrects for any dip from load (AC & steering) pretty quick. I haven't bothered touching the torque reserve table though & have left it zero'd out.

    I'm going to try a slight trim of the min-idle table as it did move from 18% slowly down to 16% over 10-12 seconds when i pulled up to set of traffic lights in gear & it's trimming spark down ever so slightly. however i also forgot i turned the AC off, so it wasn't cooling my supercharger water down either.

    Something i've been playing with big time on this car is the pedal demand table, i've dulled the absolute shit out of it down low to keep it driving in a straight line and work as a built in traction/torque limiter. otherwise it'll blow the tyres off all the time if your not careful. it'll make 18psi from 2400rpm if i let it have 100% etctp.

  3. Stock maf = perfect idle. Big maf = unstable idle. Any tuning suggestions?
