E38 Torque reduction spark retard.GM SEMRET

[hymey]

maybe not related to your problem, but have you turned off burst knock retard?

Do u have b2522 in your os. Set those to 0. b2515 set these to 0 they are torque mulitpliers, which will result in 0 nm torque reduction. "Torque reduction by spark" click No.

b2522 seams to be the key though. As it states maximum timing pulled. These have to be 0. You can send me a copy of your tune if you like.
