Re: Audi v8 with ITBs
Minor update - haven't been looking at injection or ignition lately as I've been down to the lower level mechanics, but currently reassembling engine after the rebuild:

Re: Audi v8 with ITBs
That all makes sense. I haven't had a look yet, but is there anything in RusEFI for misfire detection yet? Out of curiosity, what actions would a factory ECU take when detecting misfire, aside from turning on an engine check light? Would it try to alter timing or fuelling to compensate in some way?

Re: Audi v8 with ITBs
Cam sensors For future reference, some detailed information on how the cam sensors behave on the Audi 40v 4.2 AVP V8; apparently this is the same in the 5-valve V6 engines too. Pages are in German, but it has the very helpful waveform illustrations: image.png image.png In summary, they cam sensors ...

Re: Audi v8 with ITBs
short wiring diagram for this ..?? (I have one free arduino nano) It's literally just what you see in the video - choose any digital pin to drive the LED display, choose any other digital or analogue pins (and assign them in the sketch at the top) to wire to each injector output. I chose the first ...

Re: Audi v8 with ITBs
... I'll share the sketch once I've tidied it up a bit. https://www.instagram.com/p/CMItUm-FrWY/?utm_source=ig_web_copy_link Each column of LEDs corresponds to a cylinder of the engine. The first LED of the column will flash white while the injector is commanded to open, and then change colour depe...

Re: Audi v8 with ITBs
Have you already cut the connector off on your harness? What's the probability of you getting another harness with connector still in place? Hellen121vag needs a 30 second promotional run on a v8 that would be huge for Hellen and rusEFI marketing :) Would love to help, but I don't know if my engine...

Re: Audi v8 with ITBs
Hold on, what is the original donor vehicle? Any chance that this 8 cylinder engine would work with the https://github.com/rusefi/hellen121vag ECU we are trying to finish _soon_? As OrchardPerformance says, the donor was a 2002 Audi S8. Other variants of the 40 valve 4.2 v8 appeared in the followin...

Re: Audi v8 with ITBs
I've now raised a merge request to add the AVP's firing order (1-5-4-8-6-3-7-2). I'll add a whole engine definition eventually, when I make a bit more progress.

Re: Audi v8 with ITBs
but I won't be using the electronic throttle in the final project, so I built a simple arduino-based standalone unit. is not that too much extra effort? why not start with rusEFI ETB as separate wires and depin those later? I already built it while I was waiting for the Proteus :) Very simple PID b...

Re: Audi v8 with ITBs
Haha, fortunately not that engine, no. Some variants do suffer from a propensity to timing failures, but those tend to be the chain-driven engines. The AVP that I have is a hybrid chain/belt design - it has a timing belt for the exhaust cams which has proved to be very reliable, and short chains con...

Audi v8 with ITBs
Hello folks, I'm new so introducing myself here. I'm located in the South East of England. I'm building a mid-engined sports car of my own design, with a TIG welded tubular steel spaceframe chassis, VARTM moulded carbon fibre bodywork, pushrod actuated suspension, and moderate aero. Styling will fol...

Re: How to compile the firmware
Building on Linux, it's sufficient to do:
Code: Select all
git clone --recursive https://github.com/rusefi/rusefi.git
cd rusefi/firmware
make -j $(nproc)
