Just curious since I'm wiring in a gauge myself, are both ecm/PL and gauge hooked up to the same sensor?Between the coolant temp in Powerlogger vs the Autometer gauge, there is about a 15 degree difference. Which do you think is more trustworthy? The Autometer gauge/sending unit is of unknown age, FWIW. It's an electric gauge.
edit* The reading in powerlogger is the higher one. Gauge shows about 170ish warmed up. PL shows about 185-190
