Hi all iv managed to frazzle my ecu. Fan on ect.earthed the ecu but cant access use diag port to reset tps. Advice very welcome
If you are looking for a replacement Avanti race parts sorted me out when mine failed. They offer a few options. Exchange, repair, replacement and custom mappings if desired.
What bike? Guessing 999 from your profile. ECU model? I take it you have inverted the fly lead polarities? Try this, connect the Fiat adaptor by itself to the diagnostic port. Connect the -ve black fly lead to a good earth on the engine or frame. Turn on ignition. Do the fans stop. If the do then identify what would be the middle wire on the 3 way superseal diagnostic connector. Tap a wire into it and run the wire to the -ve (negative) terminal on the battery. This should sort the problem. A second hand ECU may be the best solution. I can help you with any remapping/immo flashing.
