i have to agree with fordfairmont. chiptorque now have an ezyflash system just like the capaflash system for the b series.

very good results and mine is going in on monday on the gold coast to get the unit and 5 custom tunes done... although this is for a turbo forester. There is nothing better than the standard ecu for options as you still have cold start and knock sensor options which most aftermarket ecus dont have

the chip is only as good as the tuner and they do not lose tune over time.
