5 years ago @Dron_Gus was thinking to rusEFI this vehicle https://www.rusefi.com/forum/viewtopic.php?f=15&t=1096

5. Five. Cinco. years ago.

He no longer owns this car. Now that he no longer owns this car finally it's the perfect time to rusEFI it right?

Inside the heat shirk sits LM1815 - this did not go well with 2nd VR channel so far so we have withdrawn to "7 without 6" Subaru trigger decoder.

Open question N1: where the hell is TDC on this 7/6 trigger wheel or maybe where the hell is it on this specific vehicle? Internet give us this magic picture of the symmetrical 6 tooth wheel which we cannot use due to it's symmetrical nature

Open question N2: what is the source of this sweet picture? How official is it?

Next traumatic episode was trying to figure out which coil wire is routed to which coil, and which injector wire was routed to what injector. On all the wiring diagrams wires come in and out of a magic igniter without any clarity on which signal ignites what coil.

In the end it turned out that injectors were numbers in the natural cylinder numbering sequence while coils were numbered in the 1-3-2-4 firing order.

Fast forward four hours of banging head at an unknown TDC location we found some random offset which was at least firing up the car somewhat.

While we have https://rusefi.com/forum/viewtopic.php?f=2&t=1883 just start right away (that EJ18 is wasted spark) this EJ20 seems to have TDC in a very different spot, or SOMETHING is very different. It makes no sense. Unfortunately I did not save tune and log of EJ18 since well, there was no tune - it was just starting right away. Weird.

Could it be that flipped VR wires on the TLE8888 level is still not 100% same as inverting signal on the firmware level?

Objective data we have:

1) poorly synching trigger with "inverted" https://www.rusefi.com/forum/viewtopic.php?p=41006#p41006
2) not synching with current gaps not inverted which _maybe_ shows more reliable gap sequence? https://www.rusefi.com/forum/viewtopic.php?p=41007#p41007

And that's the not always synching trigger which shows reasonable RPM in TunerStudio but clear scheduling gaps in rusEFI console

clear pictures with the timing of teeth on 6/7 Subaru trigger wheels. Also for 36-2-2-2

We have two or three people thinking that physical inverted VR on TLE8888 is not compensated by just "inverted" in settings

And we might have data to prove that point - once we've flipped the wires we got better sync!

With VR wires flipped we've also updated trigger definition in firmware a bit.

Idle valve works now, MAP sensor is finally showing reasonable values once we made fuel mixture less than crazy rich. Next step wiring in AFR sensor.

On the Subaru the VR sensor wires are shielded and the shield is connected to signal ground too. If you swap the wires you are basically using the shield to carry the signal and this can pick up noise like an antenna.

On this Impreza VR sensors are connected through 3 pins each: separate pin is used for shiled. See https://github.com/rusefi/rusefi/wiki/Subaru-Impreza-1991-1996 .

Last thing we have tested - AEM AFR gauge connection through CAN. Work like a charm.
Did not have much time to run long VE auto-tune but also seems to work.

Next step is to run my custom board on Subaru SVX...

A few amazing engine sniffer pictures while we were shopping for reliable start.

Posted: **Wed May 26, 2021 9:20 pm**

That's a great example of the magical wasted -> sequential transition while starting!

Thanks to Pavel and Pavel car is now drivable

Cranking and Idle is not perfect yet... due to trigger we suspect.

Posted: **Sun May 30, 2021 6:04 pm**

That was....pretty good actually. Sounds like there's a lean spot, then it richens up.

This start is on 7+6 trigger. Previously we have been using 7 minus 6 - and cranking was a bit better.
We suspect some offset between 6 and 7 patterns that cause such start. Also trigger error blinks few time on first rotations.

maybe engine sniff it? See if it's actually missing ign/inj events or not.

Yes. I definitely need to check real trigger signals. But next weekend only.

Autotune on the way to office.
Have no idea is it good or bad due to leak of experience.

Log and tune is now here... Have to upload to new car, because previous was created by AndreyB.

"AFR" is it measured value? Or target?
I have AEM AFR connected. Can it measure AFR=90+?

Screenshot from 2021-06-01 14-13-02.png

Posted: **Tue Jun 01, 2021 3:18 pm**

Yes measured. I believe 9-22 or 9-25 is the common range.

So AFR=96.335 does not look like correct value?

Posted: **Tue Jun 01, 2021 4:03 pm**

Does not look right to me

Posted: **Tue Jun 01, 2021 5:32 pm**

Nope, that's completely reasonable. Remember that free air is infinite lambda/afr, and at that instant you were lifting off the throttle (big transient!) so a matching transient on AFR isn't unreasonable.

Posted: **Tue Jun 01, 2021 5:36 pm**

Yep, that's just full scale lean. Maximum output of the AEM X-Series is 6.5535 lambda (2^16-1 / 10000), which is an AFR of 96.33.

Posted: **Tue Jun 01, 2021 5:37 pm**

If you manually set the lambda/afr scale it tells a much better story:

Thanks!

I'm going to flash updated FW and try new IDLE fixes.
Was not able to reflash ECU today. Seems STM32F427 has bug in USB flashing mode that cause dfu-util to fail flashing under linux...

not all changes are merged yet, but in theory you could rip a bin out of the github artifacts for this PR (or checkout and build yourself): https://github.com/rusefi/rusefi/pull/2745

yeah, a number of people have had trouble with dfu-util not working...
