So the 2 sensors we tapped into are throwing codes. When you clear them it runs fine, until the next start when it happens again. They WILL NOT auto clear. I backended the app to allow passive deletes and they still come up.

Is it possible that GM is running tighter parameters so that these can't be piggybacked?
You probably need a couple updates to get the JB4 booting up faster like the newer Fords do.

It's not really practical for me to do development support on the forum (I won't be able to check this thread daily) so best to just email me the logs and details.
