6L80E Trans Torque Management - How to Reduce Duration of Timing Profile?

[DRTWRK]

Can someone lead me in the right direction. I have done my due diligence with the search feature but unable to find specific answers.

I am noticing on my logs (profile as reflected on my chart) the duration of time from when my timing starts to be pulled and when it recovers is taking longer than desired.
I know there may be several tables that effects the timing profile but would like some help on identifying which tables would have the greatest effect in reducing this "timing pull duration" Specifically when it starts its ramp, how long it stays at the min set timing and when it ramps back out.

This is a fully built 6L80e with an E38 and all hard parts currently available and approx. 900 + rwhp.

I do believe the use some torque management is necessary to make the trans live under abuse and know the 6L80e can handle a lot more power than many believe. But the tune is and always has been the key to survival.

What is the commanded shift time during this?

Hard to say without a tune and log file. The commanded shift time is a big part of this, but other things are happening as well (ie disengaging the TCC, filling clutch solenoids, etc).

You may find some relief in changing the field [TCM] 484 - Speed Control Termination Mode to Immediate. Otherwise, if you have it on a ramp setting there will be additional delay during the ramp down and up process. Additionally, what may LOOK like a long ramp can also be caused by a slow polling rate for the channel data. If you really want to get better timing data, remove as many channels from the log and set the polling interval to 10ms to isolate the event.

Aside from the data in the log file, what is the human experience like? Are you noticing any actual drivability/performance issues?

Thanks Guys

I've been a member here for about 15 years but seldom make post or send attachments. It seems I can attach the .hpt file but not the .hpl

My .hpl log will show the extended timing pull that allows the engine to fall on its face due to the timing being pulled dwn to around 3 degrees before the shift completes. The 3 degrees is what I have in the Min Timing Torque Management but in the past has not pulled the timing long enough to feel the power loss.

Probably need a little help with this also.
