My father and I are doing beginning a project together to make a fully programable engine managment system by this summer. He's made controllers for 4-cyl, 2-cyl, etc. but nothing for a rotary. My dad plans to get the PC board designed by summer time (as this is a side project) and I need to do all the programming. I'll be instaling it on my car first to test the system out but he plans to sell a few for fun. He's estimating that it'll cost $400 for the system. It'll be a limited production but it'll be a lot cheaper than any other system out there. He runs Control Systems Inc. http://electroniccontrol.com. There's not much to look at but for credibility purposes. I'll post updates on the project as it progresses.

Sounds cool. What will you be using to program it?

i am learning assembly language for the processor and then use visual basics for the Windows interface.

sounds cool. if everything works out good, i can take one and for that price my friend will prob jump on one too.
