Hi, 3.7 twin turbo having an issue with surging. Torque source is reading "oscillation" and cutting timing. I set the Spark only torque ratio for OSC/Antishuffle to 1, but this didn't help. Researching the forums I see that a lot of V8 guys having similar issues and they remedied it by disabling shuffle logic under ETC, but I don't seem to have that parameter available, Is there any to other way to stop this "oscillation"? What is the root cause?
