    Check all connections for that sensor including plug, grounds anything that may be loose. If in the end all checks out then possibly sensor is failing.

    Should be easy enough to figure out if you're data logging.

    Now that I have the MAF close the P0106 wont go away, I tryed changing the Min Max on the MAP by 20% still setting code. The sensor is running around 71 to 79 at idle is ther a way to calibrate the MAP sensor?

    From what I have read and done with mine, (running 2 bar SD) I set the low table to the minimum throughout and the upper to max. Not sure if that is 100% correct to do but it has not affected any drivability issues and solved getting codes.

    Easiest is to use the histogram that matches the P0106 table and start populating some values, then add a few kpa to give you some head room.

    How did you make out with the MAP code?

    just trying to get ducks in a row for when i fix the p0106.Do I need to change the PE delay to 0 rpm enable torque to 0% and set enrichment to 4. and what about changing the band accumulator i hear about. I thought the 4L60 in my truck all ready had a corvete type style from the factory.then there is the upshift torque managment how mutch should that be reduced. just a few questions in my head.

    PE KPA should be around 95 if I remember correct and table should be stioch divided by desired (14.68/12.5=1.17). And yes 0 the remaining columns under KPA. I don't believe the 4L60's have the stronger accumulator but read http://www.hptuners.com/forum/showth...CC-TM-(w-Pics)
    Very good walk through for trans tuning.

    This may be a dumb question what table should stioch divided dy desired be in and what does 12.5 represent.

    EQ ratio is what I think you are asking about.

    So 14.68/1.180 = 12.44, or something similar. Thats your PE fueling. Also don't set the enrichment ramp in rate to 4.0, keep it at 1.5ish for NA cars.

    Stock KPA for enable is like 55 kpa, the delay is 5,000 and the enable tq is 100%.

    I set them to like 75 kpa, 1500 rpms and 50-75% enable torque. The factory throttle % is 90%, lower it to what you want.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    I got 1.126048 for the EQ ratio. Do I populate the whole EQ string with this number or do I use this as a multiplier.

    MAP code seems to have been fixed last two test drives the CEL has been quiet. Thanks for the input now on to better tuning.

    I believe if I understand your post correctly that 1.126048 is your multiple by percent value.
    Glad to hear you cleared up the codes.

    1.126 is pretty lean if you ask me, thats right at 13 afr. I would go richer.

    I think I got lost on that, is the 1.12 an error from logging or just the actual reading?
