there isnt one, two wires send voltage to the tb and for the nex nmu to work there isnt a broad enough spectrum to read the volatage. i installed a wot switch under my wifes pedal. she doesnt have a tune or pulley so the car is ran with 110oct, one step colder plugs, on a 75 shot the dyno is below. no detonation and no timming was pulled. after pulley and tune we'll up the pills and see what she does
