Post by Volkkarijermu »

What you think about rpm:
http://www.saunalahti.fi/markusco/roina/megatune2.avi

Wasted spark with bosch 0 227 100 204, dwell 4.0ms and discharge period 1.0ms. 12-1 wheel, trigger angle 57, no MAP used only rpm ignition advance. No fuel used. Board V2.2 with 029q.

What should I try? Megasquirt resets itself about 5 times when driving one hour.

To me the rpm looks fairly normal. relatively stable, slight hunting, nothing to write home about. I would personally hook up the MAP sensor so you can have a true timing map. Even old style mechanical distributor systems had a vacuum advance can that made the ignition map rather complex.

As for resets, that's usually due to inadequate grounding or ground loops or noisy power (failing alternator/regulator)
