now let me tell you dont follow the instructions they send you as far as just daggling it near the throttle the wire is delicate and looks like will snap after about of week of driving and wiggling. Ill do a small how to later. I have to find some hardware for the thermocouple. I did get some intresting readings while i had it attached to the cold pipe. my temps went up about 1 deg every 45 seconds of stuck in traffic time.
