    LC1 with hptuners Pro A/F readings extremely rich?

    I just installed an LC1 with hptuners did the whole add EOIO and make sure LC1 is selected. Did the free air calibration and such installed the sensor(Which is used). Now I'm reading 7.36 as my A/F in hptuners. Just wondering if a decently running car could possibly be running this rich or is the sensor or my hptuner settings off? I have a scan of me revving it a few times but not moving and it holds around 7.3. AFissues.hpl

    No would say your WB is not setup properly...post a screen shot. By your use of "EOIO", I would say you are using 2.24.

    Also I never see your commanded AFR do anything but 14.68, even with a MAP of 100 kPa...be careful. Figure out why you aren't going into PE..

    I didn't go into PE because my tps setting on it is 90% so no issue there. Still confused on why the wideband isn't reading correctly :/ but ah well I shall try doing another free air calibration

    WOT at 100+ kPa, 4000 rpm and 17+ms of injectors, I would be worried.....

    Have you verified what the transfer-function is, as
    the LC-1 puts it out? I know my LM-1 will put out an
    arbitrary scale & offset that can be programmed, and
    uses a default I don't much care for. What's the source
    instrument have to say, and what does the HPTuners
    wideband function (also programmable, with some
    default or remembered-setting) "receiving" the voltage
    think it means?
