    LC1 wiring with gauge

    I've done my due diligence in searching but it's still unclear to me where my ground locations should be. Why can't I ground all wires (2 for sensor, 1 for gauge, 1 for EIO connector) to the same place? It seems like this might prevent a discrepancy between the gauge and recorded lambda in HPT. TIA.

    Me also. The problem I have is the innovative gauge and A/F reading in the scanner table drops to 21.3 in free air when I connect to the EIO. As soon as I disconnect the LC-1 Brown wire from the EIO, the Innovative gauge returns to 22.0 (correct free air). I am studying and looking for the correct configuration to use in the LogWorks software to program the LC-1 to read correctly in HPT.... Any suggestions?

    You might have to change your voltage offset.

    I attached an excel spreadsheet I found here.
