But all resolved now and now I can focus on scaling my MAF and then move onto VVE with accurate information obtained.
    Glad to hear you found the problem!

    Thought that was the issue?twas not?while watching my logs the commanded afr shows roughly 11.3-11.5 actual is yielding 15.4-16.2 noticed the alternator is charging rather inconsistently but is still testing good. Anywhere from 12.8-15.1 on the DIC. I?m going fkn crazy with this thing 🙄
