Actually...I did a little cost benefit analysis and determined that I would probably be better off sourcing the system from someone like PVL. I've got the part numbers I need now...I've got Aaron pricing them for me.
To build it myself I'd have to go with a higherspeed MicroController than what I'm working with now....it's just too slow to make the calculations needed at higher rpms. The faster controllers are not particularly user friendly....I'd be looking at learning a C variant, buying the compiler software (at least $500) plus the hardware to burn the chips...plus most of them are "Burn once" chips, so the only way to make them programmable is to burn an interperter into the eprom and then build a flash memory setup to hold the actual program.
I really wanted to do this myself...but in the final analysis the payoff just does not justify the money and the hundreds of hours I'd spend on perfecting a design.
I'm going to keep playing with the BasicStamp MC anyway...see what can be done with it. On the internet I have seen some basic programmable systems made with inexpensive PIC's, most of them in some small way don't do what I want...and I don't have the knowledge at this point to modify them to my needs.
Nothing pisses me off as much as not learning something I want to learn....but I'd just have to dedicate too much time to this, to the exclusion of other things that need to be done.
I am playing with ideas like a variable length intake track driven by rpm and throttle position, using a PIC driving a servo motor that moves some velocity stacks. Kind of a reverse EXUP valve....electronics are a cinch....the mechanism would be a bitch.
I could slip it by tech as part of the "electronic ignition"
