    Default AFR readings low through EFI

    I just hooked up PLX M-250 to EFI. EF Iis logging afr @ 13.6-13.72. Voltahge is fairly steadt @ 1.8 Volts in data folder.

    I measured actual voltage from sensor to EFI and voltage was right @ 2.3 Volts, or 14.6 AFR. Why isn't EFI converting voltage properly? Could scan mode be set improperly in edit, properties, logging? It is currently set for stream fast. PIDS seem to be fine!

    What am I missing?

    Think I figured it out. PID was configured for EXT1. I wired up PLX as device 2.
