    please help! trouble with lc1 and hpt pro.

    I purchased hpt pro last year and hooked my existing lc1 that was in the car into A/D input 1 and ground 5. Everything worked just fine, was able to scan afr and it was same as what my gauge in car was reading.

    Somehow over winter it stopped working, gauge in car still reads just fine but I got nothing when I try and scan? I went over the wiring and re-ground it all but still nothing. Its like the EIO stopped working? Any thoughts?

    never mind got it figured out. For some reason my EIO input 1 was showing "unsupported parameter" not sure why but I just reset it up and its reading correctly again.
