I came across this diagram that shows a EMB circuit layout to raise the rev limiter.


It looks plausible though I am not sure how well the transitions from a stock ecu fuel cut to total batch additional injection states would work.

Is it possible to overlay batch injection on top of sequential using diodes like this?

I don't plan to implement this rev limit feature.... but I would like to use this type of functionality in a no money down custom fuel and spark autotune circuit.

Any thoughts from all you piggy back guy(s) are more than welcome?
