hey got my z32 ecu that has been modified to suit rb25det its has had all the work done to make it run an rb25det and retain vvt was tuned and installed by boostworx Adelaide and the car was running a tdo5h-18g, s15 480cc injectors, z32 afm, front mount, straight through 3 inch exhaust, car made 246kw atw.
as you may well know this ecu allows you to retain the vvt ability of your engine where as the rb20 ecu cannot and when you retain the factory ecu's functions you get all the good bits like cold start,acc dips non existint,knock sensor and protection (power fc cannot retard the timing when it sense knock whereas factory ecu can)
the only thing required to fit this to any rb is that around five wires need to be changed on the pin out not an overly hard task at all and i can provide the changes when the ecu is bought
