I was going to suggest you talk with Lucky13 on the MaxDirt forum, but I see you already have a thread going there. I had a wiring issue with my R6 a while back, and didn't have the top injectors plugged in correctly. That put the box right into safe mode on me. If you don't, or didn't, have your injectors plugged into the harness correctly, I'm almost positive you will need to reset your ECU. BTW, when the box is in safe mode, it disables either the ignition or fuel to limit the motor to only running on two cylinders.
