We support odd fire, I am sure we will get it decode once you get it to spin and fire spark without fuel with sensors hooked up.

What's the current state? Does engine crank? Do you have VR input wires to uaEFI? Do you have everything wired?

Any photos?

Easily document cables and wiring harnesses.

https://github.com/rusefi/rusefi/wiki/uaEFI has the answer

Current Version: 8.0.1 Well, we got older.

Project stalled for the forseeable future, I broke a rod or something

While cranking? While revving? While not rusEFIing?

this was traced down to a severe enough drop at the main 5v regulator that would cause the main MCU to power down, aborting enabling 5vp, entering a loop. We still do not know real root cause right? Similar looking boards one would work another would not, right? https://github.com/rusefi/uaefi/issu...

C'mon someone has to start using tle9104?

https://github.com/mck1117/tle9104-breakout seems to be using older KiCAD so we now have https://github.com/rusefi/rusefi-hardware/tree/main/tle9104-breakout

Any updates?

Do you know part numbers for those while and black ECU headers for me to add on https://github.com/rusefi/rusefi/wiki/OEM-connectors?

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)

Please use rusefi.com/online for tune and logs

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
