    LM1 says 22.0 while scanner shows 14.8.

    I just installed my LM1 and after the free air calibration and setting the output voltages to 2.95 and report rate of 1/6th, the LM1 box shows 22.0 while it reads 14.88 through the HPT scanner at idle. I have the sensor in the stock location for bank2, sensor 1. I'm running open loop with the MAF sensor enabled trying to dial in the MAF. Also, the afr is changing when I rev the engine, in gear or not, and the commanded EQ is not changing.

    Is this typical? I've searched all the stickies and have been reading for months and have not come across this. Any help/insight would be appreciated.

    Attached is a scan log and config I used. Can someone tell me if it seems that my WB is reading correctly or how I can tell for myself. Is welding a bung in the header and going to closed loop until the LTFT's are learned the only way to truely tell?
