I haven't grasped all that you've written about this but could it be that the controller is faulty? Did you swap it out for another unit?

It does happen, you know, electronics do get sent out with faults. Some things can be really difficult to check in production.

That was one of the things that we'd considered too. We sent the original ECU back to FAST and had it upgraded to their Sportsman edition and checked. It makes it less likely to be where the problem lies but I still wouldn't rule it out.
