Regardless, AFR at 80% throttle should always be the same, right?
Were you altering the map or just looking at an identical map with a different value? Sorry, I haven’t dug into the software yet, or I would look myself. Still fabricating.

We do not have a cable throttle body, so we don’t have a cable tps. We do have Dbw tps though. Any map that had cable tps as the reference, it would stay at 0 the entire time since it’s non existent.
