Hey all, how can we soften the timing retard on full throttle downshift without adjusting minimum timing?
this only seems to happen when in top gear, plant your foot, the car hits a brick wall downshifts then comes alive.!!

I have the same problem.

I started looking at T43 now, and after I m going to do tests.

Problems...
Without any modification in T43, just speedometer and rpm limiter, this problem remains!

I did modify the torque tables, with or without modification it still retards.

I found by disabling the Torque Management on upshift.... made the transmission perform poorly, however I'm curious to know how you control how much spark is retarded on the upshift??

I wouldn’t fully shut off the TQ management. Just reduce it.
Tuning the trans shift behavior is in the ECU

Post up your file. You probably have some nannies still turned on in the ECU.
