About a month ago I did the 6.2L recall on the ZR2. When I left the dealer after the ECU reflash and removal of the Range DFM/AutoStop module, I noticed the auto stop feature was not functional the first few stops. I cycled the A button and the DIC indicated off and then on again. Still didn't work right away, but then did a couple times before I got home. I then put the Range module back in so I didn't track it anymore.
Today I picked up the Tahoe after the 6.2L recall ECU flash and once again the auto stop feature did not activate, even after I cycled the A button. I didn't put the Range module back in yet, so I'll see if it does it when my wife drives it tomorrow.
Anyway, I wonder if the ecu flash deactivated the auto stop. As for the DFM, it may have been working some on the ZR2, but I was in stop and go traffic so hard to say. The Tahoe is so quiet you cannot tell when the DFM actually kicks in.
