Can you explain this a little bit. This sound like 2stroke engine. Is this ECU one from TDM that have 2 cylinder so every 360 degrees one of cylinder have spark or something else.

How can I identify my ECU. I have XTX year 2005.
Does ECU make spark as soon as pulse come (360 or 720) or it wait some time.

Interesting. Why do you want to do that. I think it will be pain to do that because of 1 pulse. Do you want to do this through hole rev range or just at high revs. Just High isn't it.
Do you know how pulser (sprocket or something) look like. If you know do you have picture of it. I thought about replacing this one that have 1 "tooth" with one that have 4 "tooth" if his only job is to pulse variable reluctance sensor (crankshaft sensor). Later it is easy to bring this pulses (4 of them) to the ECU through electronic counter/divider (by four) that will make one pulse every 4 pulses from sensor. ECU will not notice any change. Like this you can count time (degrees) from third pulse. It would be more accurate.
