Grabbin, tried to message you. No workie. I'm using two plx gauges. One is for AFR only. The other reads both oil pressure and boost. I could have put all three on one gauge, but I want to see AFR all the time. The toughest part is finding a place to put to modules. I stuck mine behind the radio. I think you can run up to 32 sensor modules on a single gauge. They data log too, which is cool. You can recall max and min numbers.
