L9780 has internal ADC and is newer than CJ125.

And L9780 is properly available https://octopart.com/search?q=L9780

it would be amazing if some group of heroes gets us working hardware and software!

Our PCB breakout is for terminals in 3 rows while this used connector has 2 rows on PCB side. We had similar drama with 55 pin connector.

What pin on the main connector are we adding the Pull-down resistor (as seen in the pictures) to and what it the pulldown resistance? // by the way NB2 MAF internal diameter is about 2.5 inches / 63mm // 1K pull-down to read current from this MAF engineConfiguration->mafAdcChannel = EFI_ADC_6; // P...

Progress was made!

I love the threads with engine running in the first post

Any chance you can mention "rusEFI" in the video title?
Any chance you can upload your tune to https://rusefi.com/online?

this is believed to be working until someone tells us it's not

That change did help but we definitely have a couple issues here and there. https://github.com/rusefi/rusefi/issues/1488 for example

Are there any boards available to the UK?

All the files to fab are published but those boards are a bit useless until the software is done.

OEM K4m ECU is a ems 3132 or Sirius 32

Any updates? Are you still running rusEFI? If you can document how you have connected all the wires maybe we can make a Plug&Play adapter for MRE?

Wikipedia knows K4M https://en.wikipedia.org/wiki/Renault_K-Type_engine#Applications_(K4M_16v) is this related to your KM4? What year is your engine? How does OEM ECU connector look like - how many pins on the connector?

@JPh can you please post images and information on how you connect MRE to OEM harness?

Based on your progress I wonder if shall try to make a Renault KM4 PnP board?

My v12 is probably not going anywhere in 2020. One of the plans was to have it on a trailer as a rusEFI bait for local car meetups but something has cancelled all local car meetups

Thank you for the screenshot it's always better to have one!

I cannot explain this I see gppwm1_pin NONE on https://rusefi.com/online/view.php?msq=41
What does TS show for GP PWM pins?

auxvoltage1 and 2 you can simply ignore I believe those play no role. Those would be removed further in the next hour.

Correction: auxVoltage1 and auxVoltage2 were not used and dead code, I will remove them a bit further now. Thank you for pointing me at this issue! New theory: you are not providing enough details to help you effectively. No screenshot of exact error and potentially not recent tune on REO? Please co...

Bill, have you figured out your transmission plan?

have you ordered https://racehead.com.au/product/bmw-lightweight-performance-flywheel-m60-v8/ BMW LIGHTWEIGHT PERFORMANCE FLYWHEEL M60 V8 CHROME-MOLLY STEEL Hybrid product for use with m30/s38/m88 clutch ?

https://rusefi.com/online/view.php?msq=41 shows gppwm1_pin NONE same 2 3 4, that's good.

Something is using PA0 already so you have a pin conflict. Please tell something not to use PA0

In your tune I see auxVoltage1:PA0 auxVoltage2:PA0 place change those to NONE

I would recommend three improvements: silkscreen, silkscreen and silkscreen. On both sides.

It's the miracle of continuity!!!

Do you have continuity between MAX9926 output and stm32 inputs pins PA5 PC6?

In rusEFI console there is "sensor live data" tag with event counters. Do these counters go up?

Your hardware seems to work. All the remaining answers are in your settings in my opinion. A video of the board running would not help troubleshoot your settings.

If you are looking for any help from here please upload your incomplete tune to rusEFI online.

It looks like hardware senses the signals which is great news and the most challenging part!

Now you need to get into software. You need to be looking either at Engine Sniffer in rusEFI console or Composite Logger in TunerStudio. And please publish your tune at rusEFI online.

What kind of special are you thinking? So far I am not aware of anything special in similar circumstances.
