Hello,

I am planning on using an external dual VR conditionner for my MicroRusEFI. Like I do with my megasquirt.
I take a look before, and there is 5v supply on the board and a lot of analog input.

But... When I take a look at the MicroRusEFI, it's impossible to change the 25 or 45 by another analog input, like the frankenso.

Is it a software limit or a hardware limit ?

And there is the same problem with the vehicule speed sensor. Why can't I use another input that 25 or 45 ? What is wrong with the others "AN volt" ? Does the frankenso have better analog input ?!

Sorry if my question is stupid, I am not an engineer.

I can use the VR conditioner before the 25 and 45 input, I don't see problems here, but I would like to know the speed of my vehicule without using an external canbus sensor

Thanks,

Sincerely,

That's a usability improvement of rusefi_microrusefi.ini file - at the moment options are very limited to make things simpler for more normal installations. The hardware and ECU firmware have enough flexibility to run at least some of this.

For custom configurations like yours you would have to use rusefi.ini file from "default" bundle but you would have to become a bit of an engineer to figure out what goes where since with "default" file there would be no nice pin names.

I can change rusefi_microrusefi.ini to make it juuuuuust a bit less locked, let me think about it a bit later

Thanks a lot !!

I am happy to know it's a software limit.

I haven't my MicroRusEFI, and I will take a look later for VSS.
I also have a fuel pressure sensor and knock sensor that I only want for logging, it looks possible

The MicroRusEFI is small but have a lot of possibility. <3 <3

Yes, fuel pressure is supported, with automatic fuel pressure compensation coming soon!

can I use any Analog input for VSS please .. ?? ..or can anybody tell me, what need to be changed in rusefi_mre_f4.ini file, to "unlock" AN inputs in this dialog ..
... I can test it ...

Need help with this - please make custom .ini file to confirm what pins would work

once you confirm which pins work I would enable see https://github.com/rusefi/rusefi/issues/2984

so I have some time today...

Wired VSS HALL sensor to AT4 input ...
It works on hardware side ... (tested as AC switch)
but doing nothing ...

Config / tune is ONLINE
but I'm not shure, if is ini file modified corectly ..

Log file ...

please provide more context. what .ini change is needed why?

line 497... vehicleSpeedSensorInputPin

..it must be the same as line 498 clutchUpPin ... ??

please explain what is the context using words.. is this about some stm32 pin? is this about some MRE pin? what is it? what made you want to change file? maybe you want to propose mre yaml file change?

at the moment it looks like major research if what you are trying to do is needed and i am not sure when i would have time to reverse engineer your proposal

OK... start here .. https://rusefi.com/forum/viewtopic.php?p=41596#p41596

I'm try to "unlock" AN inputs for VSS...
...try to edit rusefi_mre_f4.ini file

cause MRE has only "25 - Hall Cam" and "45 - VR/Hall Crank" fields ...

but I'm not sure, if is the right way to do this ..

too vague. you did not mention one pin. i am asking to mention ONE SPECIFIC pin, i am not unavailable to discuss all pins generically

OK ..
I have connected "22 - AN temp 4" .. I have no idea which pin it is on MCU ..
(can we talk about this on slack ..?)

Just made https://github.com/rusefi/rusefi/commit/9c17dc1dfc3e4924fae8e18fe3ebce5990831a5a change

Please try new snapshot in about 20 minutes from now it would maybe have useful changes in .ini file

...it's 11.00 PM ..

I will test it tomorrow

it's working ...

Please use https://rusefi.com/online for logs

Please do me a favor and delete attached logs from both message. My preference is not to edit your messages but also not to have logs attached to forum

It has to be https://rusefi.com/online

Ok. ..
I'm mean, the ONLINE is for tunes only ..
