If it's a "Plug and play" ECU, as the wolf is touted as being, then surely the wiring diagrams supplied with the unit should contain all the information needed to install the unit, and the base maps also supplied with the unit should at least be capable of getting the car to idle.... now, of course some tuning is going to be required, quite a lot in fact, but really, a decent ECU requires a tuner who knows how to tune EFI.... A "plug and play" ecu shouldnt really have any hidden features that require a specialist tuner to operate it...
