Thread: EEC-IV total timing??

    EEC-IV total timing??

    Does anyone know what the total timing an EEC-IV PCM uses? I heard 30-32 degrees. It's in a 86 GT converted to mass air.

    The EEC adds 16* to whatever you set base at. 10* is stock so total would be 26*. A good place to start would be 15* base or 31* total.

    Good Luck

    You can pull out spout, set it to 32* or 34* the \n just leave the spout connector out, it will be locked down to where you set the timing at.
