    Are you able to log PID/Channel 4403?

    If so, try this graph. I'm curious to see where you land on the map. You most likely will need to change the break points to match your torque intervention...

    Flashing the zf8 does not appear to reset adaptives. Hence the need for a special function to reset adaptives.

    Here's another question. Does flashing the TCM reset adaptives? I'm assuming no.

    Long story, but the end result is I'm having a hard time commanding a proper first gear shift point without flair, but my car is weird with the 3.70 gears.

    ZF8 Trans adaptives

    On the zf8, has anyone played with resetting the trans adaptives and trying to do a relearn using the scanner?

    Don't want to open a can of worms here unless I can get the lid back on as this is my...

    I think you can eliminate or at least minimize your scanner issues by prioritizing polling speeds for the things that happen quickly. It works for me.

    Take a look at the torque reduction table that's near the rev limit tables. It should show reduction vs rpm error.

    That's a lot of rpm. Are you still seeing rpm limit for torque source? What is injector DC?

    What does fuel mass cyl 1 do when it happens?

    Your MAP KPA and total airflow also dip slightly right there. But VE does not.

    There are tables for fuel cut and several tables for torque reduction (retard and/or throttle). Are you logging throttle position and spark advance? What happens when it starts limiting?

    Maybe these aren't options?

    I have shift ID, shift situation, shift type.

    Many reasons:

    Engine longevity
    Fuel consumption
    Emissions compliance (if only for your own peace if mind)
    Sensor wear
    Self diagnosis (codes)

    On the first two, some could argue that a good...

    You may find lowering the WOT threshold helps with part throttle fuel trims by getting into open loop sooner. Check out some of the boosted tunes in the repositoryto see what I mean.

    Thank you again Steven! This is way more than I expected and by far the best write up I've seen on the zf8.

  25. ZF8 shift pressures and timing - for Steven@HP

    Under Trans>shift pressures, there are 3 tabs.

    General, upshift, and downshift.

    These seem to be related to fluid pressures in the various clutches. There are also some time based parameters.
