What to look for possible TM or possible KR?
What to look for possible TM or possible KR? I ataped last night saw no KR on WOT runs but I'm still experiencing a dip in power. When I am at about 67 and nail it It'll downshift hard into second then buck(serious power dip) for less than a second then go back to full power. what should I be trying to look for in atap to see if its TM or just something else slipping?
is there a field under transmission that will tell me pressures or anything
Should I be looking at the timing and see if its pulling it for a second?
Any help while I still have the auto tap I have to rerturn it to its owner at some point

Re: What to look for possible TM or possible KR? Do you have logs of the event? What were your various engine paramaters doing? (ignition, injector pw, o2, maf, etc.).
If you believe it's torque management you might try setting the value to a high number (800 or so) in LS1 Edit. I wouldn't leave it there permanently (Team ZR-1's suggestion to set it over the max logged value is the best course) but for testing you are fine.

Re: What to look for possible TM or possible KR? If you believe T.M is the issue you need to monitor "Delivered Torque". It reports how much torque is being delivered to the drivetrain.
But to do this you need a scanner that works correctly and in the case of autotap I proved to them over a year ago there was a bug.
If you monitor DelTq and you see values like 1200 plus ft/lbs of torque, thats a scanner bug, thus you cannot see the real max torque the engine is producing.
Positive values is torque output as your on the g-pedal.
Negative values are either from lifting off the gas pedal ( cell 21) or from torque management kicking in.
So if your in cells 0-19 or 22 and see negative DelTq values, T.m is involved.
I've said it before but owners either need to demand autotap fix that bug or go buy a decent scanner like the Ease enhanced scanner.
