This is an upgrade that includes a new sensor package and a single igniter. This is normally used with the Honda ECU's.
The challenge I see using it with Speeduino is that while it generates a cam and crank signal, as it has a single igniter, I think the way it needs to work is the 4 IGN outputs from Speeduino would need to be combined onto a single line to drive the one igniter igniter. The upgrade then allows that igniter to be routed to each COP.
Speeduini uses TC4424 MOSFET driver chips and I'm not sure if the outputs can just be paralleled or need some sort of diode isolation?
Has anyone looked at these?
