Very nice. The LCD looks nice and bright. I'd be that can be seen well in daylight. It has a decent refresh rate as well.

Re: Wideband Controller: Fully Custom, no ASIC!
Looks like allot of the schematic is very similar to this one Waltech did, except STM32 instead of AVR. Good to see a more useful version of the design being done. https://waltech.com/cszcms/wide-band-oxygen-sensor-project-report Once a standalone board is done, could this be merged native rusEFI fi...

Re: rusEfI based on STM32F4 (Frankenso) for air-cooled small vehicles
What opamp are you using? Opamps do not go to the rails, as well there are things like offset, and gain which are important. Plenty of opamps can actually drive to the rails - the MCP6004 used on Frankenso, MRE, and Proteus can, for example. The opamp's open loop gain is largely unimportant, as nob...

Re: rusEfI based on STM32F4 (Frankenso) for air-cooled small vehicles
It would appear you do not understand certain things about opamps. Opamps have many characteristics that are important. However with out knowing this level of information I cannot help you. It's not a question of if I want to help you, I simply don't have enough information to be able to help you.

This divider is what was referenced.
Sharing the full schematic helps us understand what kinds of issues may be happening. We can look at it and know what voltages to expect. etc.- Sun Oct 25, 2020 9:52 am

Re: rusEFI OpenGDI ECU
Is @AndreyB suggesting a board which accepts low side pulses and generates pulses for GDI injectors? Done up as a stand alone box. Similar to the high Z to Low Z injector modules that can be obtained for people who desire low Z but have high Z ECU.

Re: S1000RR Motorcycle Engine
I understand there are different algo's and different methods for how the injectors are blended. Of course you can do lots of things with FSIO, and you can potentially implement many different algo's with FSIO. For example, If load above 50% then injector PWM = 20% if load above 60% then injector PW...

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection
I think the 5V7 is absolutely critical and not very redundant. I expect you'll find 5V1 is what you really need, which will probably partly conduct during normal operation. I'm assuming you understand the 7805 is not the only thing that can dump energy into the 5V rail and that is why this diode is ...

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection
Are you familiar with the MAX9926's 85mS watch dog? You may want your layout to allow for the option of different modes. That watch dog has been a thorn when cranking. The 5V7 on the 5V is likely to allow more like 6 or 6.5V before it starts to really clamp. This can be catastrophic for many chips o...

Is this a Ford Ranger with an electric motor? The ECU uses an STM32, but I don't see injector or ignition controls. Am I reading the schematic wrong?

The attempt of a boost voltage valid LED on R0.3.2 does not work. It appears the diodes do not drop the voltage enough and U1 gets destroyed.

Re: CAN support
By far the most poplar is the M12 5 pin, followed by the M12 4 pin. I think you'll find the M8 is small and easily damaged. However if you have a fairly low stress environment, and you have space concerns, the M8 is smaller.

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection
A very common igniter failure is caused by not gaping your plugs. Over time the gap gets larger and the primary voltage increases until the driver fails. When the igniter breaks then the voltage goes back up and you burns up your primary wingdings. All the car's I've owned have been from the mid 80'...

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection
Don't forget the Waltech WO2 option. It could be made into an integrated option. Some code porting would need to happen. Also would be good to select automotive grade op-amps if reasonably possible.
