I'm inclined to think that my issue is unrelated to the TSB flash. No one else who has received the flash has encountered a no-start condition.

One of our members whose vehicle has never been flashed this side of Brampton has an identical no-start condition with the sc tune removed.

The fact that I now have two ECMs is always a possible source of the tuner's confusion. I have had the tuner connected, for clearing codes and running performance comparisons, to the car with the B&G-flashed ECM installed.

I'd consider this the all-clear for any of you who have been holding off getting the flash pending the outcome here.

As stated in the prior post, I've only recently learned that it is necessary for the tech to invoke the Warranty provision to enable the flash to a vehicle whose VIN is not on the original "authorized" list.

That item of information, plus the full printout of TSB 18-031-05, should be all your tech needs to accomplish the flash.
