This was a matter of loading A4 tune in PCM not modifying M6 tune.

Im lost as to why scanner stops recording on the launch when racing and trying to data log, any ideas?

I have a 2001 Z28 and I pinned out m6 pcm for 4l65e trans I swapped in, now the car starts fine and dies. I have P/n and in gear rpm set on tables at 1000 and it says desired rpm 0 and stalls once...

Does this mean torque management is where you would tune this problem?
A diff. thread says to adjust burst knock timing below 1000 rpm to lessen the effects of it.
