Yes please! That would've been nice.
I can compile the schematics into one pdf.

How do you suggest I upload them though?
I'm not familiar with github or such.

Ready for the board house!
Did some reading up on the lates Proteus v.03 and decided to follow the same track and went for the current direct ADC sampling knock input solution.
The components are already in stock, so I guess I'm just around the corner

I downloaded the Proteus_f4 bundle to play around and familiarize myself a little bit in TS. How may fuel ever be enabled while "Injection configuration" is grayed out? Is there some other setting that needs to be enabled first? I've already played around a bit with trigger and engine conf...

Getting somewhere. Progress.jpg Remaining to-do list: - Routing analog inputs - Laying down PWR and GND planes - USB connector and pressure sensors placement - Figuring out Knock circuit pinout and routing Will hopefully be ready to upload Gerber files and order the components that aren't already in...

The thing that will make onboarding the easiest is to use an identical pinout to proteus - all inputs/outputs on the same MCU pins. If so, the firmware should "just work".

Word, that's what I'm going for

I ask whether an adapter is reasonable because there is nonzero cost required to maintain additional board configurations. Keeping the compatibility matrix as small as possible is good for everyone :) It's a valid point, but to me it's about having a nice and more or less complete plattform to star...

USB: I've planned to use an FTDI FT232RL as the USB/UART adapter, primarily because it's well supported by TunerStudio. Which STM32 pins are suggested for TX/RX? Any other approaches that are considered to be better with the STM32F427ZGT6? This is a very worrisome statement. My preference is to be ...

Can someone point me in the right direction for the correct knock DSP chip connection with the MCU?

It's on!

It seems the F4 doesn't support direct USB connection though. Am I missing something? I am pretty sure that F4 supports direct USB we must be talking about different things. You're of course right :) I checked the datasheet for USB specifically, and the same pins are indeed used on this device. I g...

I've come a long way in the schematics work and currently using Proteus v0.3 as a reference. First I'm noticing is the fact that the schematics on the github are for the STM32F767ZITx MCU. How significant is this? Latest Proteus was populated with stm32F4. There is a chance that 144 package is 100%...

- I require an integrated WB controller and have already designed the hardware for this. These things could easily be remotely mounted and used via CANBus. AKA minimize the length of the sensitive analog signals. Also note that wheel speed sensors, accelermoter, GPS, EGT, etc can also be done remot...

Either way, depends on how much i-o you need. With extra stuff you probably want more i-o so 144?

Thanks.
With the ECU case i have in mind (90-way) and after I've seen what has been done with the Proteus, I'll probably end up with the 144.

The main cpu may not meet the timing requirements for dithering the nernst current, so it might require a second mcu, but that's OK. That shouldn't be an issue. My design uses an analog 1kHz sine oscillator for reading the nernst cell impedance (and thus temp) in real time and outputs two analoge v...

Iiiiiinteresting. Might be worth creating a separate post about this one, since I've thought about implementing a wideband controller from scratch like you've done. The CJ125 is sort of unobtanium and finnicky, so I'd love to not depend on it. Cool! I'm happy to share some schematics once I start o...

I don't think your engine has any highly unusual needs, so just the MRE or the Proteus board may be the way to go from a hardware standpoint. I view it a bit differently. Here are some of the features the Proteus doesn't include that I would like to have on-board for my design: - I require an integ...

In my aircooled days I have read much about de-shrouding the Wasserboxer to go air-cooled. Very cool project and everything looks very well executed.

Cool to see more airheads on the forum. Here are some pics from the conversion process:

Hi RusEFi Community! It's about time I take on the next step in my development work, and I've been looking into this community for quite some time. I just started my freshly built engine with a set of 3D printed intakes that I've designed myself. Up until now I've run my own MS3 based ECU design and...
