I expect you were within 200 rpm of the bin?
Back with the original version 1 processor they had hidden parameters that had to be setup in the mtCfg files that were there to only allow "those that could" get it to work. I learned a few years ago but do not have it up on my mind at this time.
It had looked to me that the V2 processor they had the auto tune working for all to use. Unfortunately I have not used any B&G code since Extra came out years ago, so I also need to read. I did try to use the B&G code this past summer but only to learn the code did not allow a 1 cylinder engine to run. I swapped processors for the old V1 and all was good. Hard to think I was the first one to try and get a single to run on the new processor.
