little update on this. eventually saw a max of 12 (1.2 KR) on the gauge but does not read this very often also saw 5 (0.5 KR) on the gauge at one point as well. Both was at wot. I re input the xgauge command for gm vehicles and now i have the decimal point (maybe they updated the code) but i havnèt seen a reading on this new input yet LOL so i will report back again haha
