Negative Trigger Angle ?

Post by bluetrepidation »

After matching my trigger offset to my timing light my trigger angle came out to -10.5 (After TDC correct?) and seems to drift off when I increase RPM. This makes me think that I may have my spark output set incorrectly? The MS is controlling timing because if I manually turn off my bypass signal I can see a change in the timing.

MS II, on a Saturn GM DIS module.

Solved. High current driver was interfering with the signal. Removed and now everything is dead on accurate.
