Hello, good afternoon everyone, I have a problem with my microRusEFI R6.0, when connecting 12v to the tunnerstudio the indicator gives 21.4v, which may be generating this fault. I listen to suggestions


and I tried to look for the menu Base Engine->Battery and Alternator-> Battery Input Divider Coefficient, but it does not appear

Please confirm that you've connected battery to https://rusefi.com/docs/pinouts/microrusefi/?connector=main&pin=5

Maybe a photo of connector?

"Battery Input Divider Coefficient" is not adjustable on microRusEFI since all units are supposed to be the same. Have you purchased your unit or made it yourself? If your wiring is right this looks like a fabrication issue.

Hello, I assembled the microRusEFI myself, I attach a photo of the place where I connected the 12v

..then you have something wrong on HW side ..

are all other Analog Inputs OK ..??

[diegort5]

Yes, I have tested 3.3v and 5v and it is fine, the only anomaly is the 12v voltage reading.

This looks like JLC fabrication not by me? How many boards do you have / who makes them?

[diegort5]

I manufactured it, I ordered the board from jlpcb and the components from digikey, I am an enthusiast of the motor world, I come from speeduino and now I want to know rusefi, I have already tested the functionality of this ecu and everything is fine except the voltage reading

How many boards do you have?

meaning "can you test on another board"?

That's actually vague. Who has done what percentage of soldering? Is this 100% hand-soldered by you unit?

I tested the exits and entrances using ardustim, 100% assembled by my hands

Please assemble a couple more boards and compare behavior.

..as I see on first photo ...
(probably)

all OP-Amps has bad soldered pins ..
some other IC also ...

few resistors not looks so good....

..probably too many problems on it....

solved, friends, it was actually a cold welding on a vbat resistance, the repair with the cautín and problem solved, it will continue with my tests thanks for the time given to everyone
