Im thinking of buying the G-TECH on-board dyno, it reads your 1/4 mile time, hp,0-100 time,storage of drag times and a lot more. Its plugs into the cigarett lighter socket and thats it, i have no idea how it works and can tell so much info from this? it retails from $535au. Does any one have one or know how they work? and if so do they give a correct reading?
Cheers
