    How do I log AFR with MPVI2?

    I just purchased a MPVI2 and am wondering what methods I could use to log AFR. I have an Innovate gauge with external outputs and am not sure how that would connect to the MPVI2. I have a GM vehicle

    The non PRO version right?

    If so you have to wire the wideband into a 5v reference circuit on the computer if one is available, then create a custom channel to log it. This is very popular on the older computers from GM like the P01 and P59.

    Otherwise if the car is much newer, most will buy a AEM OBD2 wideband as it's plug and play with a can-bus vehicle.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
