Re: Software knock processing

Thanks Andrey. I wish I were more help on software, but looking at the code I feel like a six year old attempting to figure out how an Airbus A320 works.

Re: Software knock processing

it's currently only on some boards (Proteus and hellen?) Frankenso has totally different electronics for knock, the not-software but ASIC approach which did not work out for us. This thread saying "Software knock" means "not ASIC like on Frankenso" Understood, but what I'm askin...

Re: Software knock processing

I'd really like to use knock logic in my project, but I have Frankenso. I understand it's currently only on some boards (Proteus and hellen?). Is there a reason we can't activate the logic on other boards? I have no issue repinning the harness to put knock on ADC03.

Thanks Andrey. I couldn't have done it without a lot of support from you and the rest of the community (particularly MCK and abricosvw).

Re: Teves mk60 Standalone ABS

Ooh awesome, I'm very interested in this. Will I ever get around to installing it on my own car? Probably not. But I like the idea of it. It would be really cool to see a programmable ABS ECU that could use more common hardware, as it's a bit tough to find the M3 system.

Re: E85 / Flex fuel logic

Were you actually changing something to change the E content, or is there a bunch of noise somehow? As mentioned on slack, not changing fuel at all, just low fuel level and multiple key on/key offs (see battery voltage switching between 5-12v). So it may have seen some air bubbles and voltage swing...

Re: ETB setup - startup pin state

Ok per Matt's suggestion on slack, I tried tuning the bias curve before trying PID auto tune. It appears to work once there is a reasonable bias curve in the calibration.

When I auto calibrate the TPS the thottle opens and closes, but PID auto-tune isn't really working. The throttle makes an attempt to open, but only opens a few percent, and doesn't do the os...

Re: ETB setup - startup pin state

Problem identified: image.png You've picked a pin that's hard wired to some other function on that board. You can't use PA9. Looks like I chose two bad pins. I was trying to use PA10 for the other one, which appears to also be on this USB circuit. Back to the diagrams to find a couple unused outputs.

Question: does any rusEFI user have a real flex sensor on a real rusEFI vehicle already wired into a real rusEFI ECU?
I have one in a vehicle, and could easily connect the signal to RusEFI. Engine is destroyed, but I could still run fuel through the sensor and check it.
