    Timing is at 0 degrees under full boost

    On MPScan under full boost my timing is at 0 degrees is this normal? If it is not how do I change it? I am using a Logic module system, 20 psi.

    keep adding timing in your AdvanceFromMapWarmFull at that boost level till it knocks. then back of a few degrees.

    mine was at 13deg at 22psi in the log before it knocked. 93 octane, giant intercooler. 2.5, 50 trim g-Head. DONT EXPECT THIS WITH A SWIRL.

    what im getting at though is that it seems that the table values dont totally add up to what the MPScan log says. also, double check your log by logging ADV with a OTC scanner just to check.

    Wednesday it's supposed to be in the sixties. A good chance to see what the OTC says. I recently moved the curve up from where it was, really a very sharp down curve. I may be able to put more adv in yet.

    Upon further thought about it I realized that I did run a test with the OTC in the summer and it does go to zero degrees. So, what is the meaning of that?
