I borrowed a high dollar snap on scanner,,,,,unhooked the water sensor and hooked the wires coming from the computer up a 2 step module and started putting in different resistors to see what water temp it thought the computer was seeing,,,,,after i got a few done from 100 to 220,,,,,,I started making runs. I also hooked up an EGT guage to see how hot the exhaust was,,,,,,the reason I used a 2 step module was so later, I could put a swith on the shifter OR use an RpM activator to switch fuel curves in high gear......it seems to work fairly well,,,,,,,the one thing I did notice, at least on mine,,,is that its extremely consistent if and ONLY IF actual water temp is in the 125 range,,,,if it climbs past 140, it slows .10 and does not repeat, even if you try to run it at 140, it wont run the same thing twice,,,,,,,,,also ,,,it doesnt appear that weather bothers the car,,,,last run 2 weeks ago was 15.57,,,,,,,,,1st run this week was 15.57 with a 7 or 800 difference in adjusted altitude,,,,,,,,the egt was reading 1335@ the 1/8 and 1475 or so @ the 1/4 mark,,
