So it seems that the stm32 chip being broken is the culprit of strange reading I'm getting in tuner studio.

For clarification purposes but dose, the op-amp has inside divider ratio or are two resistors like R214/R215 does that, because at op-amp output leg I have 4.91 but after those resistors, I have 2.45. and after those resistors track goes straight to the stm32 pin

Yes changed it to 3.27 now the raw voltage dial shows around 5v, but I still have the same problem the temperature doesn't move past 50c and with nothing connected shows 8c, doesn't correspond to ohm calibration. What voltage I should be getting at an stm32 leg with a disconnected sensor? I have 2.4...

I have 3.27v on pins and in tuner studio i have 3.00.

AndreyB: Yes Frankenso without discovery, you mean this?

kb1gtt: op amp with no sensors connected have an output of 4.91v on leg 8/9 and 13/14, and at stm32 pin I haves 2.45v

And checking the 5v rail I have 4.99v, and voltage after pull up resistor is 4.98v or at pin that clt/iat connects i have 4.98v.

A2: ecu is powered by a bench power supply 12v and amp draw is around 0.09-0.10. It is connected to a 12v-switch pin and ground connected to a big pad labeled GND near the sd card slot.

Short background story, while playing with sensor inputs accidentally connected 5v pin to 12v source, blew my MAX9926/TPIC8101 and some pull up/pull down resistors. Now they have been replaced but I think i have more blown parts. Question one: Can a stm ship be shorting too but still can connect to ...

Probably DFU. Jumper between VDD and BOOT0, will elaborate in a few hours

Yes, this helped me to program without st-link.

Serial bootloader? https://www.st.com/en/development-tools/flasher-stm32.html Don't get your question, yes? I need to connect my pc with stm so i could programme the chip but on rusefi wiki I see that I need to place jumpers on the discovery board, but my problems is that I have directly soldered s...

Hello, I am new to this forum, got interested in rusefi when I was looking to buy ms, maybe half a year ago I bought frankenso and now I finished assembling/soldering and need your help. My problem or question is simply where do you short stm32 to program it, as my board doesn't have that stm discov...
