Hellen 154 GDI VAG

[AndreyB]

Let's make a GDI Hellen board for my Passat, test it and junk the Passat. Test mule thread see https://rusefi.com/forum/viewtopic.php?f=2&t=1631

Open source https://github.com/rusefi/hellen154vag-9.1

So, we need to replicate


This plywood is microRusEFI + PT2001 prototyping board which we have. I believe that between https://github.com/rusefi/rusefi/wiki/VolkswagenPassatB6 https://github.com/rusefi/rusefi/wiki/Passat-GDI-wiring and https://github.com/rusefi/rusefi/wiki/MC33816-PT2001-dev-board and https://github.com/rusefi/rusefi/wiki/microRusEFI-Manual we have all the information needed

We have an early draft at https://github.com/rusefi/hellen154vag-9.1/blob/main/boards/hellen154gdi_vag-a/board/hellen154gdi_vag-a.pdf

I believe it has issues - start1-start4 should be traced directly to stm32 GPIO without any low-side drivers. Hopefully we have four GPIO to use.

While I have $$$ to order the board I totally do not have the time to review the schematics Jared is working on. So if anyone would be interested to step in it would be pretty cool

https://github.com/rusefi/rusefi/wiki/Passat-GDI-wiring has pictures of how my test board is wired and https://github.com/rusefi/rusefi/blob/master/firmware/config/engines/vw_b6.cpp#L83 and next 20 lines of code show the hard-coded configuration just as an example, we can totally use different pins the key point is which pins have to be wired.

Worth noting that MattD from Rabbit ECU MD has same connector on his test mule. Waiting for MattD to document which pins he is using that would tell us what pins we shall have

all my projects are in storage since I'm currently stuck in an apartment

between those two statements I wonder if you are the person to finish this board?

I'd love to give it a shot! I'll have to brush up on my Hellen knowledge a bit. Last I checked in it was just a concept. I'll have to re-download slack and get back to speed. Might not have a ton of time until the weekend though.

Matt's notes are now

I've updated first post with a summary of what's going on here

Also worth noting that Vlad made some changes to board outline while working on Hyundai board which uses same case. That's now https://github.com/rusefi/hellen154vag-9.1/issues/8
