Without tune and log we are blind, please share your tune and your log. Two VR channels are of different nature - one uses ASIC max9924 but has a 85ms timeout making it not suitable for small tooth wheels, another one was designed by mck1117 that one does not have timeout but you are in charge of tu...

Welcome to the forum!

Linked below?

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?

or map sensor in case of odd-fire engine

cam 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.

Without knowing engine phase engine is running in wasted spark mode.

Welcome to the forum!

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?

Appreciate the write up!

Is there an official value for this resistor, or does it have to be found through experimentation?

Добрый вечер let me recommend https://github.com/rusefi/rusefi/wiki/Discord

Zero relation between vvt outputs and sycn.

Please https://github.com/rusefi/rusefi/wiki/rusEFI-Quick-Start-PDF#log-it and https://github.com/rusefi/rusefi/wiki/rusEFI-Quick-Start-PDF#share-it

TODO support MAF sensors like 04E906051 see https://github.com/rusefi/rusefi-hardware/issues/146

Yes but you would have to use "blend" tables feature - it's powerful but complicated.

VE is insane, that often means that injector dead times are wrong.

let me point you at part of your tune responsible for VTEC control https://rusefi.com/online/view.php?msq=1652&dialog=gppwm1

I had my trigger wired to the discrete VR and its supposed to go to the 9924 VR

Your choice not to search for existing threads on obd1.

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?

Many years ago I had a not so bright orange vehicle with a Honda K engine. It has blown the head gasket for not good reason :( So I've decided to purchase a bright orange vehicle, again with Honda K engine, this time GDI and turbo-charged! And Acura Care Extended Warranty :) WhatsApp Image 2024-05-0...

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

this has definitely turned to be way more work than I anticipated

Alexey @vag0dr04er has contributed _something_ - right now it's available in Proteus firmware, let me see if I can also enable it for 4chan and uaefi
