On the ad it said it was 100% suitable for ep82 and ep91. It doesn't hit fuel cut, works fine. I have an oem ecu dude, as far as i know anyway :s. Im not too familiar with electrics TBH, my friend does all my stuff (works in a car electronics store), knows what he's doing. Anyway, when i went to get the fuel set up the guy said we cant run it at a bar as planned cause of the wires being cut, so he said buy a new fcd n ill do it for nothing when you have the new one installed. so i got the new one and fitted all the wires but no luck, well it ran, but cut out when you revved it and the eml was on. Just really want to know how to make it run ok with all the wires . I'll ring the guy today and tell him.
