    Troubleshooting AFR Error Graph

    Hi,

    I'm having issues with my AFR Error graph showing the wrong % error. The AFR commanded is in AFR units, however my AEM WB will show in lambda. This is throwing off my AFR to assist with OL MAF tuning.

    I'm sure it's operator error, so any assistance would be appreciated!

    Use commanded EQ ratio then because that is Lambda instead of commanded AFR.
    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.

    Hi,

    I added commanded EQ, which popped up on the graph.

    I still am having issues having my wideband turn up on the graph along with the EQ Error. Any input as to what I'm doing wrong would be appreciated!
