Started messing with throttle follower yesterday. My PCM thinks it's in 1st gear all the time (according to GM.GEAR) with the 4L60E to T56 swap, even with the T56 segment swap from an f-body. Maybe it's because my clutch switch is not hooked into the PCM.

Anyways, I zeroed out the throttle follower decay rate and decay delay in P/N (B4319 B4320). When I rev the engine the RPM's will hang at around 1300 RPM indefinitely when I'm parked. I did not try it when moving. So I put these tables back to stock and now it's back to normal. This tells me that the PCM is using the P/N throttle follower tables even though it claims to be in gear.

Other P/N tables in the tune, like idle speed and idle airflow, are also zeroed out but it's correctly using the In Gear tables anyways.

Anyone know what's going on here?

Thanks!
