The PowerFC does not have limits such as speed limiter or boost cut the factory ECU has to prevent engine stress / excess load. It has adjustable idle, rev limit and on-load idle. You can set your cars rev limit to whatever you like. 10,000rpm if you like.
There are no hardset limits in terms of power, killowatts, horsepower or turbo size etc its purely as good as your tuner. So if you have a good tuner then there is no logical/physical boundary etc. The Apexi 1200HP drag car uses a PowerFC for its main ECU (no surprise).

Are there any cool tricks with the PowerFC? Free mods etc?A handy trick PowerFC owners use when they take car in for a service/work to be done they set the rev limit to 3000rpm and remove the hand controller. .This prevents the workshop from taking your car out for a fang on the roads and driving it like they've stolen it as the PowerFC will cut the power at the 3000rpm rev limit interrupting the joy experienced by the joy rider of your precious car. This would be useful at panel beaters, car cleaners, stereo installers etc. This would not suitable for a performance workshop cos if they are tuning your car or fixing a problem they may need to actually rev it out so use this wisely. Another unofficial mod is instead of buying the official PowerFC hand controller extension cord is to use a normal Ps2 extension cord used for a normal PC computer. Its the same cable you just need to break off one of the pins.
