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

Re: 2022 Canam

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.

Re: 2021 Acura RDX

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-...

Re: 2021 Acura RDX

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?

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.

Well, _technically_ we have provisions to persist calibrations on external SPI flash and that mega board has it! There is a chance to run rusEFI stm32f407vE maybe without Lua maybe with Lua.
