I was chatting to my brother about a megasquirt ecu earlier, explainined it to him and showed him Stu's technical articles (so bloody helpful stu, thanks again) and we were talking about making our own ecu, as he's a bit of an electronics whizz to say the least (gonna be a PhD the smart arse) and he began to understand what mapping is, he asked me if there was such a thing as a self adjusting map?
Something along the lines of:

1) it keeps the AFR to Lambda 1 all the time, or whatever you set it at, slightly rich, lean, whatever you want. (I thought this is what closed loop is for)
2) Using knock sensors, adjust the spark advance constantly to get an optimum power from the engine.
3) Our own launch control/anti lag

I'm fairly sure this is already done, as my car has knock sensors, so I assume this is what they're for?
Or it could be done, but isnt for some reason?

We were just thinking of something to do, from scratch, between us as a shared project, but I cant see us getting it to work perfectly first time round, and I'm not building new engines every week

Would be cool to design our own ecu though. I suspect its miles harder than we both imagine though.
