Start with some free lessons right here: hpcdmy.co/tunebIt’s easy to talk about the likes of this 1200HP RB26 power plant and just assume it’s going to be quick, but in reality, there is so much more to putting in a fast lap time than a few high power dyno runs and Mark McCoy of MoTeC is here to help explain where some drivability and pace is recovered using the R34’s 4WD system.With the factory Nissan Attesa controller removed a MoTeC dash takes over control of the setup allowing to start dialling in the basics via throttle position and speed through to enabling the team to dial in the system for every corner on the track according to lap distance.The advantages of lap distance vs GPS/GeoFence technology is discussed along with what data is used to help tune the setup along with how it all operates in the first place.
