And also that "Ash and the guys at Z1 spent time and time again researching and finding the best way to program the ecu for results and safety/reliability."
The fact is that Ash's ECU work had nothing whatsoever to do with Z1. Most of us think they just hired Ash so they could make more money selling the Ash-spec EPROMs.
"There was obviously a reason they chose to distribute them instead of jwt chips."
They used to sell just JWT ecus, and at a time sold both Ash-Spec, and JWT. My argument is not which program is better. My argument is that you are basing some of your opinions on misguided information.
