E38 Torque reduction spark retard.GM SEMRET

[alian]

Hi Guys, After sorting out most of my KR problem i found that somthing else is retading spark. after some help from swingtan i have narrowed it down to pid GM SEMRET. I have managed to log this pid and it seems to be able to remove up to 20 deg of spark leaving me about 3deg at times. The caption says Tourque reduction spark retard. I have tried adjusting,B2502,05,10,11 and 1914 to name a few, to no avail. please if anybody has had this problem, or has any idears i would love to hear from you, the car has not got traction contol fitted to it.and is a auto.


Any help would be great, Thanks Ian

2514, 2517 & 2522 max out the former 2 and zero the last one. See if that helps.

Thanks for the fast response, Allof them are as I am running it, Have played with 2522 a bit had it from 0 to 100. at 100 it seemed to be not as bad, any other ideas.
Thanks Ian

Did you turn spark smoothing off? Apparently that helps. I pretty much zero'd or max out all the tables in mine and have no issues.

Yep B0301 is off, It could be somthing in my tune, or just a problem isolated to my car,Just cant put my finger on it.
Thanks Ian

Are you running an auto or manual? If its auto you might need to look into the T43 tune too

Auto. Have looked but cant find any reduction except at up and down shift, and dosnt seem to activate the reduction at these times. Open to suggestions though. Thanks Ian

I went pretty crazy on mine and zero'd anything to do with torque management. Maybe not the best idea. But Ill use my foot to adjust torque

Have you tried to disable torq m'ment upshifts - D9401
In HPtuners it mentions "the master enable/disable for torque reduction on upshifts".
