Just a quick update. I reached out to Holley with some questions and Jones20992 is filling out the info for MegaSquirt's product. I thought about this a good bit last night, and I think we will be adding in the information for a line-by-line comparison of the timing control features. In forum after forum, I see various bits of information... and a lot of conjecture. Hopefully this thread can be used to nail some of that down. I'm not sure how this will get laid out yet, but it's coming.
