    Hey everyone,

    Just got the URD MAF Calibrator preloaded with a map. Didnt get any instructions from gadget on how to get that map downloaded to my ECU.

    Anyone know how to do this?

    MAF calibrator does not effect the ECU, it simply effects what the ECU sees from the maf as far as i know.

    The MAF cal doesnt download anything to the ECU. It intercepts and manipulates a signal that the ecu reads. So its wired inline or tapped into the wire(s) on the ecu. I dont remember specifics.
