Hello thanks for getting back to me. The truck runs good enough with either one of the chips Ive burned or attached to the APU1. No on the inverter and I did try different USB ports but only have one ADL cable. I did OHM out the ADL cable as best I could and it seems ok. Im really frustrated mostly because it had worked good for several months while I was learning about Tunerpro and the moates equipment, then right when I felt the tune was getting close to what I wanted no more DA indications or data while logging. Cant help thinking I fat fingered something and messed up either Tunerpro or a setting on my laptop. Ive been trying to figure this out for more than two weeks now and only learned how little I actually know.
