That's great, I'll buy one off you. I'm an electronics engineer myself and found three chip faults on my unit, that's why I'm fairly sure it's the computer that's at fault and there must be more than that blown. I'll probably end up repairing mine but for now I just want to get the car on the road asap. Having a good unit to compare my broken one with will be handy in repairing the old one. You've made my day buddy. Email me on mark@traxcircuits.co.uk and we'll sort out the best way to pay you.

Cheers
Mark
