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.

Thanks Joel. But that is what it is set at already, any other suggestions. By the way did you get your car back together with the smaller cam??

Hey Ian,

try setting B5156 to "0" and see what effect you have. B5156 is the "Maximum allowed spark retard amount due to knock, torque reduction etc." so it should help.

Along the same lines B5153 could also be adjusted to set the minimum spark timing as a separate control from B5156.

Finally, B5157 gives a final minimum timing MAP to set up. You could look at your logs for the exact RPM vs gm/Cyl points where you get the reductions and adjust this MAP to clip the minimum timing to a specific point.

Thanks Simon. I can only find B5153 and it is set at 10 but it pulls down to 3 so that dosnt seem to work. Cant find B5156 or 7. Evan with the V2 plugged in.I checked You and I run the same OS but cant find it in yours either. Ian
