Yeah, similar problem. We added camshaft sensor some days later after initial startup, and the deal is done. The only thing missing now is to have siamese port support in software so that we can run the two injectors on one output each in the correct sequence instead of tricking the ecu into thinkin...

Do we have issues with the closed-loop idle control feature these days? I've been trying it on some different setups during the last couple of months, but I could not get it to respond as intended. Decided to give it another test on the testbench today. Within the idle RPM upper limit, it seems to o...

We fired up the engine with two injector outputs for the first time yesterday, and my hypothesis as stated above appears to be true; the engine runs like shit with both batch and simultaneous fuel delivery, and the spark plug pairs for each cylinder bank indicates a significant asymmetry in fuel del...

Tested yesterday. SENT w. GM-TB works like a charm on Discovery_F407 when signal is routed to MCU pin PA1

Understood. I'll switch over to one of my analog temp inputs connected to PA1 and remove RC filter capacitor on that channel
Thank you for swift response!

Finally got to test SENT on custom hardware running latest release candidate of Discovery_F407. I've removed Capacitor on RC filter asscosiated with analog input goint to PC4 pin for a clean square wave signal. If I configure the TPS as a regular analog input, I can see the jitter from the SENT squa...

Never mind... Downloaded this, and it worked:

Downloaded latest release candidate. Can't open console because of what appears to be outdated Java version. Follows link that automatically opens: https://www.java.com/en/download/ Link takes me to "Version 8 Update 381". This does not appear to be "11". Download, install and re...

I believe there's one fundamental problem to the above mentioned strategy in this specific scenario: Because it's a "Siamese port" configuration (each cylinder bank consists of two cylinders and share one port+injector), and due to the fact that the paired cylinders on each bank fire right...

In the meantime we got 64 pin option where v1 is more or less a successful prototype - https://github.com/andreika-git/hellen-one/tree/master/modules/mega-mcu64/0.1 without shrinking of the MCU module. That sounds interesting. As long as it has support for all the functions I need, I see no reason ...

I just left home for two weeks of work, so I don't have access to either the hardware or msq.

Sorry about the ambiguity; ADC4 = "Analog Volt 4" on proteus.

Is there any way you could make it possible to upload msq files directly as attachments in forum posts?

Just discovered a bug regarding Aux Linear and WBO2 #2 input while setting up a new basemap on the stimulator. Custom ECU running latest Proteus F4 release firmware. I'd like to have 2x EGT inputs that will be connected to Analog Volt 3 and 4. My EGT module has an output where 0-5V corresponds to 0-...

The generic firmware will work fine. It really is worth adding your own configuration for this board though, if nothing else it will get you correct out-of-the-box defaults and such. Once rev.B is tested and confirmed with respect to final MCU pinout and schematics naming/labeling etc, I'd like to ...

Thanks. Just downloaded nightly built discovery (updated 5 hours ago), but can't find SENT settings in TPS menu.
Is it updated yet?

I got a 12675730AA throttle body on the bench planned to be fitted to a new engine project running Discovery_F407 FW on some custom hardware. I just discovered it has what appears to be SENT TPS instead of regular dual analog output. I opened the gearbox cover and scoped the output; clean 5V square ...

That's understandable - I can somewhat relate to your OCD. I'll stick around and see if some other forum posts will emerge that covers logging specifically. Maybe there's some info on the discord too. Anyway. I'm already working on getting RevB ready for the board house. Once the hardware is ready, ...

Some assumptions here are not exactly right. With so many unrelated things on the same thread I am very confused what to respond to :( If you feel like spending the time, I would appreciate if you would clarify what assumptions are incorrect, and shed some light on the related logging topics mentio...

Got the first prototype assembled, loaded latest release of Discovery_F407 FW and hooked up my stim. Almost everything is working as intended :D Only snag I've come across so far is the choice of 5V reg - I managed to get one that's only rated for 100mA, so the voltage drops to around 4,8V once the ...

I'm currently working on an EFi kit for aircooled VW Type 1 engines with singleport cylinder heads+intake. Singleport = one intake port shared by two cylinders on each side. Hence, I'm going to run one injector feeding two cylinders. This seem to fall somewhere between "Single point" and &...

Thanks for the great feedback, man! :) 1: The crystal I use in my designs has caps integrated. 2: It's a good input. I've become quite used to the convenience and robustness of the 9926 over the years on my other ECU designs. However, single tooth cam triggers w. VR has shown to be a bit problematic...

I assemble all my PCBs in-house.

Just ordered a couple of STM32F405RGT6 from two different sources on Aliexpress. Let's hope they're of decent quality. I've attached the schematic. Input is much appreciated :) Unless I should make any adjustments to the schematic, the Gerbers are ready to be sent to JLC. TMB_TMB_mini_48_RusEFi_rev_...

in search of a way to implement Microsquirt CAN-I/O expander into RusEFi in order to be able to read more analoge inputs etc:

What would it take to make this leap?

So do I.
What's the time step interval in your log? Mine is more or less exactly 10ms.

The sync latest ratio plot on your 60-2 looks very high-resolution compared to a fully functioning 36-1 plot I have from a selection of different engines.
Was this recorded during cranking?
Have you enabled/disabled any logging related features in TS to make what looks like a very high sample rate?

I suppose it's time to get the oscilloscope hooked up.

24-1: IMG_20230420_114119.jpg Syncs perfectly while cranking without spark plugs in the holes for max and smooth rpm. Doesn't sync well when compression and variable rpm is present. Battery is decent, and the rotation speed of the engine is quite good while cranking. Sensor on cam (distributor), not...

Is this thread posted in the wrong sub forum?
No takes on the 24-1 CAS trigger unit?

Been fighting with this trigger for two days now and not getting any luck with it. 5V hall-sensor conditioned through a MAX9926 w. 5V pullup on VR+ and floating VR- (trialed and tested Hall-input config. on the MAX9926).
