Misfire detection

[Sam@TDi]

If there's enough processor budget left I'd like to see misfire detection protocol based on crank tooth acceleration, this would be very handy, especially in endurance racing as it would save trolling through the knock logs in a hurry to try to finger a problem cylinder, knock signal alone of course not being the best way to detect a misfire.

Perhaps it could feed it's calculated results into the already existing section of knock control sub routine in order to label a cylinder as "failed" after perhaps a user defined period of consistent [misfireXX = true], thus turning the injector off?
