At high RPM, things are happening way too fast for direct CPU control, things like ignition and injection timing. Some triggered counter/timers and PWM modules could do what you need. I'd choose an FPGA, but I suspect you can get add-on chips that can do these functions. Possibly something like the Beagle Bone with an additional board would do it. But, of course, no RT on that, yet.
