hi all, anyone fitted a USA ECU. Im thinking of fitting one to do away with the HISS for a keyless ign. What has to be done to fit this?
Pretty sure @lambchops has a US ECU, he definitely has keyless ignition and I know he doesn't have HISS because he said so on a video.
Just make sure you don't get a california ecu or you might be losing power! Why do you want rid of the hiss? Hrc ecu will do away with the hiss from memory
Don't put an US ecu. They are designed to works with their fuel 89 from memory and the ignition mapping is poor after 10 000 rpm. Not a good idea lol
