FP3 wrecked my ECM
Used it for several months, but started getting some strange reading saying that there was no ECU present. My motorbike suddenly broke down and has been unusable since. The ECM is damaged and, according to the Harley dealership, they have seen this several times. So, £520 for a new ECM + fitting charge + retune - the FP3 has cost me around £1500.
