Are you feeding your unit just with USB? What is the voltage on the 5v outputs at the moment? mck1117 is it wise to feed sensors from proteus +5v without +12 power? It is potentially undefined behavior. I would expect to see 4.1-4.5 volts on the 5v sensor outputs (and on the internal 5v rail) when ...

is that with Dave?

Nice numbers!

looks like dave himself sitting in the left seat

Here's the Lua that was running for that video: https://gist.github.com/mck1117/626174d991183cc72802074f954db97b It just waits until it sees the "I'm alive!" message from the pump, then starts sending. The 1ae0092c frame seems to just keep the pump alive and listening/sending over CAN, and...

Is this only the GDI injector drivers? Or complete plug&play ECU for 4x GDI(like VW/audi TFSI engines)?

This is an external box that JUST controls the injectors/pump.

Update 2:

https://www.youtube.com/shorts/_dKSxinSiyE

maxxecu sends IDs 2104136 and 1ae0092c to the pump

2104136 is ~71.4hz
1ae0092c is ~2.38hz

exact 30:1 ratio

pump responds at 11.84hz, which is 1/6 the rate of 2104136

wow it's really 123456

is this correct firing order? really 123456?

Sou there is a way to trick pump, on that same forum and thread, 0e410003 - can bus alive will start up with no delay, and 2e414003 seems like affects pump speed by editing second byte (in index 1), but after 5 seconds pump enter fail safe but it will keep last speed what we sent to can in failsafe...

rewind motor to 3 phase and use with pwm

I don't think that will work - I think it's actually a switched reluctance motor, so it has an incompatible number of poles/phases if you wanted to rewind it in to a BLDC.

Matt, it would _totally_ compile on Windows for sure.

I'm sure it would, but it's going to be easier and more performant on WSL or "real" Linux.

Hi, I've spent some time to figure out how to compile the rusEFI-Code with the right version of Make and the GNU Arm Embedded Toolchain, this works fine now (despite the 17 warnings), but I am not able to compile the unit_tests. I didn't make any changes to it, I've got the repository-files from Ap...

just a question rusefi dont have squirts per cycle?
on speeduino used 2 squirts ,on 4 squirts i have very rich idle

can you post your tune at rusefi.com/online?

Whst is the workflow? Can to sutosports to 4g or wifi? Correct. It has a GPS/accelerometer/etc, and talks to the ECU over CAN. In my case, I have an rpi acting as the dashboard for the car connected to the Racecapture over USB. The Racecapture then uploads telemetry either over WiFi to a wifi hotsp...

update: it looks like since we last discussed it, we've added those back. They're present in snapshot but not the last release.

In the future, please check on snapshots if you think something is wrong or missing in the latest release.

Looks fine to me?

Do they have any uplink and remote app?

What do you mean uplink and remote app? They have a website that you can look at live telemetry (and lap timing data): https://podium.live/events/ldrl-2022-04-24-ridge-sun-8-hour/device/happy-cactus-240

I use https://www.autosportlabs.com/ and it works very well. Talks to the ECU over CAN. Even has a preset for rusEFI!

The log in this post contains the same ID, 1b200002: https://www.diyelectriccar.com/threads/volvo-electro-hydraulic-power-steering.44828/page-5#post-1046821 That log shows similar behavior: One frame of 0451, repeated frames of 0f71, BUT THEN a transition to 0f73, which presumably means the pump was...

why not upload an unlisted youtube video?

I upload firmware to my board but green and blue led blink alternating quickly at boot and then slowly (Firmware integrity check fail). You need to either: Disable the bootloader. Set USE_BOOTLOADER=o in f0_module/board.mk, then flash the resulting wideband.bin to your board. Build using the script...

Nick says that MAP (yellow line) spikes are explosions in intake collector?

Yeah, I'd believe that.

A few observations from your tune: Displacement: should it be larger than 2 liters? Trigger offset: Setting "single tooth second half" with a trigger offset greater than +-180 seems wrong to me. You should be able to switch to "single tooth first half" with an offset of 53 instea...

Can i run the injection in a Semi-sequential without changing the sequential wiring? I don't want to run simultaneous, so it will fire pairs of injection? Injection isn't your problem. Injection phase largely doesn't matter, since an injection can't get past the intake valve until it opens, which t...

Logs, dude. There are valuable nuggets in those logs about what's happening when it mis-syncs and kicks back on the starter.

What does "better 80% of the time" mean? Can you take a normal log in tunerstudio of whatever you're seeing, both the "good" and "bad" cases?

Abricos says that with old firmware has not problems like this.
Any suggestions?

(I am refering to usb connection and no bluetooth connection at all)

Can you describe the specific problem you're having? What steps to reproduce, and what do you think should happen differently?

Let's KISS and prototype with a brass bolt

A simple screw is actually less simple - a screw through a PCB will creep he fiberglass, making the board thinner, progressively making the connection worse.
