Some engines are two stroke and some engines are four stroke.
On a four stroke engine crank position sensor does not know when to ignite.
How do you address that challenge?

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.

Well, that kinda works David says: Any 8 or 10 speed is going to be a clutch-to-clutch transmission, which is very much not supported currently. Oversimplification: A clutch-to-clutch transmission has a solenoid for each clutch, including torque converter clutch. An old fashioned transmission has s...

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?

Re: Honda OBD1 Trigger Settings/Timing Drift Issue
It has a 24 tooth wheel for the trigger rpm signal in the distributor and another wheel that has 4 teeth for sync. Would it be safe to assume that you did not hit "OBD1" preset and probably have wrong trigger setup? See also https://github.com/rusefi/rusefi/wiki/All-Supported-Triggers#12-...

Hold on, does this vehicle have THREE separate CAN buses?!
https://github.com/rusefi/rusefi_documentation/blob/master/OEM-Docs/Honda/2021-Acura-RDX-data-lines.pdf
Power steering uses one bus but electronic gear shifter uses two? Two buses between ECU and ECU?

Re: subaru gt turbo uaefi
it's usually one resistor away working, just an open question if that's a pull-up or a pull-down and what value maybe try a few combinations?
are you trying low side or high side output?
Consider asking at the rusEFI discord server

Re: Sporttrike 1.8l Toyota 1ZZ-FE [microRusEFI]
Any MAP and throw MAF away. Bosch 4 pin TMAPs with integrated IAT are a popular option
rusEFI has "ford/toyota" redundant TPS and PPS modes that's what you are looking for
What if your oil pressure sensor breaks while you are turning? You would have to use Lua for this safety feature.
