Downshift Knock Questions
Is there a way to reduce the timing the car sees when a downshift occurs? I see in Torque Management there is a Downshift parameter, is that the parameter I want to adjust? I basically want the timing to go to 0 when a downshift occurs to eliminate any KR I see when a sudden downshift occurs. Anyone know which table and what values I need to set it at to do this?
Thanks,
Amir
This is on a 4t65e-hd transmission too.

I guess you could scan for "delivered trans torque" at the shift where you are getting KR and then enable torque reduction in that table to see if it helps. What is your WB reporting as an AFR when this happens?
