    Default Speed density

    Thinking about giving speed density a try for my dry nitrous setup. Anyone have a SD tutorial? I think it can be done without unhooking the MAF.

    Without Unhooking the MAF - Engine Diagnostics -> MAF-> Parameters-> MAF High Frequency Fail 1 = 0. It will drop off the MAF.
    Hope this helps some.

    Dry shot? Are you sure that is safe? I thought dry shotted cars needed the maf?

    Why disable the MAF? It compensates for a multitude of tuning sins and is an excellent "safety valve". A lot of people seem to forget that 1986-89 F-bodies and Corvettes used Mass Air systems and didn't even have MAP sensors, so there was no SD fall back capability. These systems worked fine and could handle some pretty exotic engine combinations.
