Your ECU is only as good as your tuner...
Even though the Motec might be better than either of these two ECUs, if your tuner doesn't have experience in tuning the Motec, it will be useless.
In Sydney, only one person has a vauge idea on how to tune the FConV, but several have good experience with the PowerFC, and have shown excellent gains out of them. Suffice to say, the majority of Australians use PowerFC as opposed to FCon ECUs.
In short, get the ECU that your tuner has experience in tuning... That is the best way to get the most out of your car.
Merli.
