Just got an engine back together for a 2012 truck, e38 ecu that was previously tuned by another shop. Hook up and start scanning and all it will read is commanded afr (10.5 for some reason) and a couple temperature sensors and oil pressure. fuel trim's aren't even showing up in the list of channels to add. So I discon/recon and fuel trims showed up until I actually started logging and then they grayed out. Now they won't show up at all, after several attempts. Google has nothing, or I at least dont know what to search for. What am I missing here? I did find that ltft's were disabled in the tune, but on other cars that doesn't matter, they just read zero for me.
attached is screenshot of the only channels I can read.
