I got my R33 up past the Supposed 180KPH limiter :wassup: , I have had the car 4 a few months and it has some HKS magic sprinkled over it like Dump back, Intercooler, Timer, EVC. But I am a little unsure of the Management. Can anyone tell me if that box on the underside of the parcel shelf is the ECU? I would have thought it was the Imob&alarm but the previous owner thought it was the ECU. I am curious as to the position of the ECU, I always thought it would b close to the passengers feet. Behind the kick panel?
