It has been busy around here, new grandbaby, new house, and catchup work on the farm due to cooler weather. I started to do some more layout and packaging work, but stopped that thinking I had better be 100% satisfied with the unit first. The last change of adding the phase sense in distributor reduced crank time when starting. The starting while quick, sometimes acted like timing advance was not well controlled. When cold on first start, it would be too advanced. By capturing reference signals, I determined that engine slowing due to compression, resulted in advance timing. That is something I worried about in 2003 when I built my engine management for 4 cylinder VW engines. I incorporated locked timing while cranking, but later removed it when found unnecessary. The higher compression V8 has more cylinders, so going to locked timing at sub idle speeds would be a great fix. I thought about it a couple days to figure out how to best add the feature to the COP system. I was pleased that the solution was simple, and it worked flawless, including the ability for multi-strike. I now feel 100% about the system, and plan to continue development into a product.
