    Default silvertop ecu with map

    has anyone tried this?

    given that the afm VS gives out 0-5V as with a map with PIM output of 0-5V

    then an additional IAT to ECU

    and an ignition switch activated Fuel pump with no more OCR.

    can the stock silvertop ecu's mapping handle such a setup with tuning?

    Metering and calculations are completely different between the two.
    For AFM ECU does not need to know the engine's VE curve, for MAP it does.
    Good luck with it, but I doubt you will achieve anything vaguely ok.
