Hey all, got my truck to run this past weekend withh the timing pill #1. I want to play around with the MSD software and program my own timing curve and map advance curve. The timing portion is quite simple in relation to degrees and RPM. The map advance scale is showing PSI to degrees... how are the two related? I know when there is 0 PSI there's "full" engine vacuum. Meaning as vacuum decreases, pressure rises. But how and where do istart with the map curve!? Very confused here, hoping someone helps me.
