    Let's talk VAF part numbers 197100-X

    For some odd reason I've been curious about some Denso VAF part numbers lately, and trying to identify what it means...and also maybe it'll aid in finding a more suitable replacement for boosted applications.


    Non Cat BP V CODE 197100-4120
    N/A BP U CODE 197100-4110
    BP26 VAF Y CODE 197100-3700
    GTR VAF R CODE 197100-3660
    F2T 2.2 K CODE 197100-3420
    7MGE Supra 197100-3300
    RX-7 B CODE 197100-3250
    RX-7 A CODE 197100-3240
    ST185 Yoda 197100-3720 *new*

    So this leads me to think that the part number has to do with the maximum voltage sweep and maybe even the spring tension. Any thoughts or inputs?

    got some numbers from a friend @ Toyota for the 7M-GE air flow meter.

    with ignition switch on measuring plate fully closed 3.7-4.3
    measuring plate fully open 0.2-0.5

    Idling 2.3-2.8
    3,000 RPM 1.0-2.0

    Resistance Fully closed 200-600 ohm
    Fully open 20-1,200 ohm


    So that's almost spot on the BP's specifications of 3.8V ignition switch on, and 3.3V at idle. Also the resistance sweep is almost the same too...promising lol

    edit: n/a bp is 3.8V ign on, not 3.3V. Also the GTX ECU runs 3.8V ignition on, and 3.0V at idle.

      The 7M-GE VAF works great so far on my BPT setup @ 8-9psi. Car pulls hard in every gear now and doesn't seem to be choked out by the inadequate flow from the U code VAF and the weak spring door...the Supra meter is as large as the RX-7 one, but I believe the spring door to be stiffer since it's setup for a heavier 200hp 6cyl engine vs the 13B which is closer to 180hp and less weight.

      I had it adjusted 7-8 clicks (can't remember exactly, it was at 6 then I started to fine tune one tooth at a time) counter clockwise.

      Idle hunts a bit, but I may have an air leak in the VAF as I had it apart to clean it and inspect it.

            Figure I would bump this to see if anyone wants to try some other VAF options out, and give us feedback.
