Public service announcement: V0.5 is published on GitHub: 🎉🎉🎉 https://github.com/mck1117/proteus/releases/tag/v0.5 🎉🎉🎉 image.png TBD if/when a batch will get run, I know there's already some interest over in this thread: https://rusefi.com/forum/viewtopic.php?p=39441#p39441 Changes: Added onboard ba...

I am developing a carrier board to support dual controller modules. They will share the +5v power supply and the CAN output. Electrically, it will appear on the bus as two nodes. I added termination bits to the board as I imagine this will be one of few, if not the only, CAN device being used with ...

I can choose what to log in the rusefi console ? Actually, I just have files who appear when I run the console.
Or do you mean the csv file from the high speed loggers ?

yes, that CSV from tunerstudio should do

Can you log the cam and crank signals, and nothing else? I want to see what the real trigger shape looks like from your engine, not whether it's getting decoded or not.

That sounds like a challenge

hasn't failed us yet....

Speaking of testing: My Volvo race car has two O2 sensor bungs right next to each other, just after the turbo - I added the second some time ago especially for testing multiple wideband controllers/sensors at the same time. For this test I raised the idle to ~1800rpm, then varied the target air fuel...

Can the software compensate for the fact that the M70 crank pully is 4 teeth off the M73 timing? You can see the sensor mount is dead center on the 4th tooth after the missing tooth on the M73. My Hope is rusEFI can compensate for the pulse difference . Andrey is this true? no problem, you can infi...

After a lot of research I finally realise that the 2JZ pattern from rusefi is completely fucked. With a friend, we take the signals from cam output and from ignition of cylinder 1 with an osciloscope. We realise that it is completely random. That why I had 1 chance on 12 to start. I try the Honda 1...

To people interested in getting their hands on one of these controllers: I'm waiting on a bit of testing to be completed before announcing wider availability. As soon as they're available, this thread will be the first to know!

If this is PnP for the M111, then presumably it is PnP for a late run M104 with the addition of a few more inj/ign drivers, no?

That is the plan, yes. The 4/6/8 cyl ECUs are the same, just with some missing some output drivers.

first Pic upload. More to follow

rusEfi is going to be happier if you cut a tooth off that crank trigger wheel

I am setting up a Frankenso 0.5.6 board at this time. Anything special about that board?

In that case, you can use any analog input, provided that you install a pullup resistor on that channel.

Very excited to see the progress on the flex fuel sensor. Any recommendations/requirements as to which pin to use? I know it has to be configured as open drain with a pull-up. On proteus any digital input will work. On MRE, you should be able to use the analog temp inputs or the cam input. Analog v...

Do we have a sample tune and sample log of the sensor actually working? Do we actually log flex fuel? :) We log it, the channel is called "flex ethanol %" or something like that. You can watch the impact of target afr changing even as target lambda stays constant. I tested on the bench with a funct...

And you probably didn't see the question a few posts up, but have you ordered the v0.5 Proteus? I was trying to compare and didn't see any difference for 0.4 but I'm sure I'm just overlooking something There hasn't been a v0.5 publish yet, even though the latest in master says 0.5 on the board :D T...

Ok that's super awesome.

On older vehicles you use the HS outputs after you run out of LS outputs so it's now worth the bother to rewire. That's the only use I've ever found for them. I guess new vehicles have stuff that is HS from the factory And sometimes there's a mix of both for no apparent reason. The factory GM ECU f...

I will ask a bit of a layman question, but is this WBo2 Controller board already supported in Tuner Studio in conjunction with the latest Proteus firmware? Because I don't see it on the drop-down list in the EGO Menu, but I don't know if I'm looking at it correctly because I don't know all the name...

Also, I'm working on getting the BOM for ordering the parts for your v0.5 proteus. R906 value is 1. I'm assuming this is 1kOhm? Can't find a value listed anywhere. Nope, it's not 1k, it really is a single ohm. It exists to add ESR to C1006, as they together form a snubber to damp out ringing betwee...

Oh! I figured it had to do with power consumption concerns. There's plenty of amperage from the EEC relay anyhow so couldn't I jumper your 12V to 12V_MR pin? I can't really see any benefits from adding another relay if I've got enough amperage stock? Then I could just leave pin 1 disconnected. The ...

Hmm. I saw the stuff about the main relay in the wiki but wasn't sure if it was needed. The stock wiring has a battery constant which I assumed 12V was, and a hot in run and start which I assumed was the same as 12V_MR? I do have them wired separate on the board. Any reason to use a relay specifica...

Also, do you really want the main 12v and 12v MR both connected together? If the ECU has a pin switched by the main relay, you want that one connected to 12V_MR, and the ignition switch connected to the other.

Looking good!

You can move this 12V MR trace to the back and avoid needing all those vias:

Most 4 pin coils are actually power, ground (power), ground (signal) and signal. That's the pinout on LS coils.

PLA is probably ill advised - it gets floppy at low temp

Very True. I intend on keeping your trace widths of 1.27mm for High Side Switches and 5V Reference, 0.762mm for Low Side Switches, and 2.032mm for 12V.

I would go wider if you can - remember those traces on the board are VERY short so they can't make very much heat/resistance.

Very very crude routing. All 12mil traces at the moment just to get an idea of trace routing. I'm not a huge fan of how I routed this. Any suggestions for improvement (aside from increasing trace width obviously)? Obviously I do have ground fill, just hidden for viewing. Analog/digital inputs can s...

You mean an ERC failure complaining that the ground pin has no power supply? You can suppress that with a "power flag" (search that in the component picker) and wire to to the GND net.
