what causes LEARN to stop in log?

It seems some of my logs show Learn to stop yet in CL.

Engine fully warmed, new heated GM delco sensor, and in CL. I am reviewing log today and all I can come up with is the TPS is at 5%. Synch Pulse Width is 1.1 mS. comes back to LEARN at 6% TPS and 1.3 mS.

it is picking up no learn from a setting in my .bin? it appears my DE is disabled(i am ok with that) and lean cruise same way.

Re: what causes LEARN to stop in log?

It may be the lower MAP threshold for learn. There is an upper & lower MAP value that learn is disabled outside of.

Check this table:

BLM - MAP learn threshold

The stock BIN has the lower set at 28.75 KPa. Once the MAP goes lower learn is turned off.
