    Set up to tune maf

    I've been searching and went through almost every maf thread. I am setting up my editor to start tuning my maf. I have the close loop enable-ect vs. iat set to 284*.

    For Dynamic Airflow i've seen to change Steady State, hi/lo rpm thresh to 0. Also i've seen to set under Dynamic airflow, High rpm disable to 0. Wouldn't setting the high rpm disable to 0 be all that needs to be done? Or do both need to be done to run pure maf? I was thinking with high rpm disable at 0, it would disable the hi/lo thresh hold anyway.

    So, i'm trying to run pure maf to tune. Any info i'm leaving out to get there would be appreciated!

    Thanks

    I think you should also reset your fuel trims, and disable STFT and LTFT learning

    1)OL & CL – Closed Loop Closed Loop Enabled – select all – type 284 in box and click =.
    2)Engine – Airflow – Dynamic Air – Steady State – Hi/Lo RPM Thresh – set to 0 (zero).

    By setting the Hi/Lo RPM Thresh to 0 will force the computer to use the MAF Only and not reference the VE table so you can properly tune the MAF with no outside fueling references.
    3) set Decel Fuel Cut Off to 284.
    4) reset and disable fuel trims as stated above
