Toying around with the idea of replacing my jet ski ecu with speeduino. I have a bad ecu in my Seadoo ski and they are pricey. It's a 2 stroke 787 2 cyl. and it has what they call DESS. It has dual carbs and CDI type ignition (driven from the ecu(mpem)). The cdi is in the main ecu with the dess (theft security and safety shutdown). The ignition probably has 3 or 6 pulses(3 phase 18 pole alternator) and the crank signal is driven at the same location. I may have to add a proper crank signal.
I have a few questions. Will this function as a ignition only system? There was some debate on the arduino site if the arduino was fast enough to do high RPM's. This engine needs 7000 RPM's. It needs a defined timing curve of 16 to 25 degrees at about 20 points. Preferably I have a shutdown of some some sort. Fuel and oil have their own systems and will not be used unless it should become another project.
Board recommendation?
What tuning software is contradicted for this project?
Is this doable?
