i had a burnt out ecu bord in my one when i got it, sent it to Engine Advantages who had it tested and replaced the faulty parts.
( incedently i had a missfire / cutting out, that turned out to be a fault in the loom that burnt the bord out but the rev counter used to drop off at the same time. sorted the short and the ECU and has been fine...
