If anyone is interested in why there will most likely never be a reflash option for the ISF, there is a chapter in Jeff Hartman's engine management book entirley dedicated to Bob Noorwood's twin turbo ISF and how the engine management was basically locked. Toyota would obviously not share how to reflash the ECU, and TRD who Noorwood was in direct contact with would also not share. Also, the throttle in our car actually is more of a torque demand signal which the ECU interprets and controls everything from there, so reverse engineering the system and interpreting the data would be a monumental task. I could go on and on but basically it is one of the most advanced engine managment systems in the world. In all honesty I've been a Mustang and BMW guy, but after reading that chapter in that book I was instantly an ISF fan and now owner haha.

Im interested too. Had a full tune on my G35 and it really made a difference.
My frind was a test driver for the ISF when it was developed and he said that the motor was absolutely detuned . Should be able to make 450 hp all day long......if the ECU can be cracked. not holding my breath
