    2004 3800 no knock pid

    Hello, working on a basket case tune on an 04 regal and have very limited pids and cannot find any knock info, commanded afr or delivered engine torque.

    Re-poll for supported parameters while connected to the vehicle. There should be a knock retard channel on those vehicles, same with commanded AFR etc.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    So I've repolled and still no knock or commanded afr. I tried an older version scanner and found a commanded eq ratio but still no knock.

    Did you click the car icon before you search for the channel?

    If you still can't find it, maybe contact support to see what is up.
