    Cant read rpms and speed

    Hi guys, have a 2017 ZL1. Was about to do some logging but I notice I dont get a read for speed and rpms in the hptuners. Was logging just fine some weeks ago dont know what happened. Already updated to 4.0 Beta but still the same problem.

    Re-poll for supported parameters. Even remove the channel and re-add it.

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

    Likely need to contact them directly via support.
