Hello everybody . I have a problem, sometimes I can't understand why, two errors are generated, code 73 aux 9/10 supply, 75 eletronic throttle position contorol error. the ecu is a vipec v88. mounted on a yamaha 1800 watercraft with borg warner turbo. I noticed (at least this time) that the problem happens when I play a bit with the throttle near a curve, and then go to wot, and that's where the errors are generated, and it goes into protection and nothing works anymore. I think it is due to the pid of the dwb, I don't know if they are set in the right way. someone is able to help me thanks
