odd fire with a 45 degree seperation. I know they did a wasted spark system on early models of this engine, but I don't have any experience with them.
i am confused I was assuming that odd fire can never be wasted spark?

Re: My harley conversion

I've only touched newer harleys and those were V-twin odd fire meaning wasted spark was not possible. Is your engine even fire or odd fire? what is the name/model of the engine?

yes we have "two wire wasted spark" using individual coils

That reminds me of OBD1 which also have three VR sensors. We just totally ignore one of these, two sensors do the job well enough.

Re: Fuel Pressure sensor

You are asking how to route an auxiliary analog input channel.

Does not seem to be routed to main 76 pin header but a couple of pins are available on the ETB upgrade option

Please use TPS2 or PPS1

Polaris is more or less the same thing, just totally different.

53 inches seems to be the perfect length if you need to do the same.

Active Dumper System, the less fancy one without stroke sensors like on Civic Type R.

Why do they run two dedicated wires to each strut solenoid? Why not shared high side?
