I went ahead and made a copy of the 121 VAG ECU pinout spreadsheet and added my findings to a later column for my personal reference if anyone wants it. There are some differences such as the addition of high and low speed fuel pump relay outputs and some others but otherwise almost mostly the same...

in order to confirm 50mA theory would you be able to please add TC4427EPA or something between uaEFI and your igniters?

https://github.com/andreika-git/hellen-one/issues/378 created since that could be an issue.

We know that current design has worked on dozens of vehicle. That makes me wonder if something else is contributing here.

going to grab a Hellen 121 for testing, curious to see what I'll be able to come up with and curiously following this build.

Please carefully review the pinout in advance, it should be fine but who knows

Wow!!! I might end up with a crown vic one day?

can't flash anything

Main MCU would take firmware via USB in DFU mode? if you had USB soldered?

PS: wanna post on the FB group and share your hellen experience while making this hellenVFR?

NICE!

I see dual WBO, do not see SWD exposed - did you get some https://github.com/rusefi/rusefi/wiki/Tag-Connect-TC2030 to program WBOs?

Random suggestion while unfortunatelly things are not perfect

do you know if tachometer is pull-up? pull-down? or push-pull controlled? how did you choose B17? What does oscilloscope say?

Another problem is that in tunerstudio, the yellow "warning" light comes on as soon as I leave idle. Please add another 992 words to describe that warning in more detail since a picture is not really an option. Lap timer? Again need another 997 works to help me understand what do you mean.

Something about merging two signals?! https://www.vems.hu/wiki/index.php?page=InputTrigger%2FAudiTrigger

No, it's too many teeth and overall should be done differently. https://github.com/rusefi/rusefi/commit/036c41ecbc2d6df58faa8d8fffb66580040b37a3

I see coil operation (green)

Is not OBD1 honda unusual in terms of using low side output to control ICM?

See https://rusefi.com/online/view.php?msq=1597&dialog=ignitionSettings

Exciting news and let von Sacher-Masoch be with you on this journey!

Please check Ip

It was a hardware design issue, Ip was shorted to GND

Same setup sensors are now flipped - problem stayed with second controller

New log, here I only have one channel working while second one is not showing any reading.

Latest main firmware logs detailed info for both WBO channels

fault code 5

``SensorUnderheat = 5``

is it possible to say anything from this log?

this was a cable mistake - dual-sensor cable had some wires going to wrong sensor

OEM ECU is definitely unusual.

Hold on, what are those blue things? Does this hint at CDI?

Some cool Ignition Coil Primary Voltage content

Wire used is Tefzel wire/ M22759/32

I see some OEM harness where heater wires are thicker than signal but Dron says it should not matter.

https://github.com/rusefi/rusefi/wiki/uaEFI or https://github.com/rusefi/rusefi/wiki/Proteus-Manual depending on your attitude towards white molex, both run same exact firmware. all rusEFI units run the same exact software.

https://github.com/rusefi/rusefi/wiki/rusEFI-Quick-Start-PDF

More or less yes.

Your overrides are worse than defaults change to 14

See https://github.com/rusefi/rusefi/wiki/All-Supported-Triggers#subaru-76-tooth I will also change 13 to 14 or 15
