hairs. Meening its based on the 440 ecu and is getting kind of old and it shows. For one you are stuck with batch fire injection and wasted spark setup as it got 4 outputs of each. If it were me i would opt for a 1280 ecu (as tokyo have gone with) as it is almost limitless in its capabilities. In my mind its mostly limited by its number of inputs and outputs and the lack of CANbus. It seems most are after PnP as they seem to think a wire in ecu is to daunting, but it realy isnt that hard. I run a wire in with a completly untouched engineharness. Took me no more than a couple evenings to make an adaptor to go in between the original ecu connector and the aftermarket ecu. With a wire in you usually get more options and freedom.
