ETC Torque Request limiting at 738ft/lbs

[R8Bill]

Has anyone had issues with the ETC torque request being limited to 738ft/lbs? I have increased all my torque management Engine and Transmission limiting values to max torque values but still I peg out at this torque amount. Any suggestions on what could cause this or how I can fix it?

Driver demand itself is limited to 738. You cant request more than that on an s550. You need to rescale and re-calculate torque and inverse so the calculated torque is less for the given load.
Have you ran into gear box limit? I think that was what it was called.

Also what does your maf # show? Does it flat line at 86# per min?

What about this one under Trans>Torque Management>General>TCC Limit. If not post tune like v4 said

Tried that too, didnt help. 738 is also equal to 1000 NM so I looked up values with this in case there was a conversion issue in HPT and increased the ones I could, but still no help. If what Thatwhite5.0 said is right, then that is probably the issue. I am not sure if there are logs posted on here from an S550 that recorded ETC Torque over this value, searching for this can take some time. If so, then that is not the problem and I need to find a solution. If anyone on here has an boosted S550 and don't have this problem, please let me know.

S550 AT TT here around 7-8psi. No issues but I tuned it the way it stays below 800Nm. No need to go all over 1000Nm. Like I said - post I tune I will take a look.
