The main difference is the auxillary and ignition inputs and outputs which is why I have chosen it, that and the altitude control for extreme hillclimbing
. To match that u need a Motec M800 and that is big money!!
Also it comes with auto tune which is lot faster and more accurate than mose engine tuners, down to 0.5%. It can map the car in 20 mins, after that it just needs tweaking. So this saves money when changing turbos etc.
