OK guys.. getting back to the nitty gritty here:

I got a father with flare for mech eng. He has built some very nice, and =
some serious cars. I'm nearly at the point of adding the I/O bits to the =
uP core system, and I realy need to know what the formula for working =
out Ignition times, and Injection pulse widths, based on any data =
needed. What I'm after is the *BEST* control algo' that anybody knows =
of, regardless of what sensors are needed (Either I'll implement them, =
or just cut them out for now :-)). I've got a GOOD tame programmer, who =
works for beer, so complexity no problem (I can even implement some =
stuff in hardware, timers and such) I just dont care, all I want is the =
MATH! Arrrrrggggghhhh. There I've said it! I've been reding bl**dy books =
for 4 whole years now, and still cant decide for myself!=20
Please help before I give up, and go back to simple amps and curtain =
closers, go mad, drink my self silly, and die dreaming of 11000 RPM and =
0-60 times in the low 4s.

Sax.

When all is said and done, RTFM. When the reply comes "WFM?",   SHOUT =
LOUD, AND ASK!

TTFN!
