New Vintage Gauge PPM
Does anyone know the default PPM that New Vintage 1969 series gauges are looking for without doing their calibration by a driven mile. I would like to just change the output pulses from the pcm to the gauge via HPT output pulse per mile or the correction factor. instead of the driven calculation. There must be a default pulse per mile that the New Vintage gauges default to before programming, it is reading 70mph at the gauge and 30mph on the HP scanner. I have already corrected the HP file for the tire diameter and gear ratio. New Vintage is was unavailable today.

Just in case anybody else ends up looking for the same answer.......It depends on the day the gauges were built. It could be 8000ppm, 16000ppm, or 84000ppm. They said it will read anywhere from 4,000 and 150,000 ppm. Unfortunately not the definitive answer I was hoping for, but at least it was an answer.

Did you figure out how to change the PPM that the computer puts out? 4K PPM is the default.
