We're tuning an M130 GPA package on a 1986 560 SL Mercedes. Trying to set CRIP with ignition locked down at 0, timing light set at 0, the ignition timing moves with engine speed all over the place, from -10 to +35. It's not steady as I'm used to seeing. I tried setting every ignition setting in the package to 10 degrees, but I still get the same ignition change with engine rpm. Mag Ref, hall Sync, no errors on ref or sync, cycle lock, 36 -1 ref wheel. Ignition 1 output for all 8 cylinders, triggering a MSD 6 Mini (because I need to use the stock distributor). Sync is in the distributor, and I've tried rotor indexing (advance weights free), and the distributor locked with the same result. The Ref missing tooth is about 110 deg before TDC.
