    Tuning issues

    Got the ski back together and started tuning. I installed the lc1 per the instructions and with a relay to ensure proper voltage. First o2 sensor read 4.2 to 4.8 at idle after heater calibration and after free air calibration. At WOT it reads 5.3. I changed sensors to a brand new sensor in the box from a local retailer. Same results. Followed instructions to the letter. Any ideas?

    could the lc1 module be bad itself?

    Shouldn't matter, I'll be putting my lc-1 on Monday and well see what happens as well.
    That's weird that both sensors do it, so that eliminates that's it's not a sensor problem, possible bad unit or a calibration or working correctly.

    Check your wiring you have one wire that might not be grounded properly trust me. The jpipe is not my favorite place to have a o2 sensor but should not affect your symptons now. I will get my charts of my install but its either a bad gauge or your wiring is not properly grounded. Where are you getting power from?

    Direct from the battery both + and - going to a relay and using the purple wire going to the gauge cluster as the remote to close the relay.
