I've run into a somewhat strange problem that I'm not sure how to remedy. I tried searching, but either wasn't using the right words or they were too short, one or the other.
Anyway, here's the situation. I'm using an LM1 with the sensor in the offroad pipe on the passenger side, angled at about 30 degree's downward into the pipe. At lower RPM's (<4000), the AFR in the scanner is showing up as 13.0-13.1 even though the box is reading 14.6-14.7. All cells under 4000RPM show +/- 1 on the LTFT's. At higher RPM's I haven't really been able to compare yet since its hard to collect data at high RPM and watch both devices.
Is this a matter of a value not being calibrated right or is it more a matter of wideband sensor position?
