BOSCH 0 261 230 340 I've already used it, it's working. Scaling data for this sensor: temperature (pin5 to AdcVcc1 or AdcVcc2): R25 = 2100 Beta = 3600 pressure sensor (pin2 to any AdcX): a = 2,50 b = -1,25 (with minus!) power supply +5V at pin 3, ground at pin 4 you can use +5V power supply from any...
Have you updated your settings with parameters I have marked on screenshot below? In settings file you have shared data logger was disabled and recording boost pressure was also disabled. I've never measured exhaust gas back pressure, first you will need to find out possible pressure range, and seco...
If you suspect water, it's better to open asap, maybe cleaning with IPA alcohol will be enough or replacing corroded resistors. If you wait, damage can continue (if it's water ofc).
Switches are directly connected to MCU via 1k ohm resistors in series. Please check this resistors I marked on image below. If they are fine and connection is fine - I worry that faulty is MCU, can not be replaced by user. And the question is - what happened, because usually more than +5.5V on senst...
I've sent you on PM update tool so you can reprogram internal flash without sending device to us. Please reprogram it to latest version to check if strange behaviour is from corrupted firmware or from fault on hardware.
Have you tested connection SW1/SW2/SW3 inputs directly to ground? Please check if wires have good connection in connector. Do you mean UTCOMP-3 or UTCOMP-PRO? UTCOMP-3 have already 4+ years, you can try to reprogramm it, I can share you reprogramming software but please let me know which version exa...
I checked these settings and data logger is in manual mode (disabled by default). Just select in settings -> advanced -> datalogger recording when ignition swith is on and it will be working.
This is good question but I had also strange issue when one of sensors was making some noise on power supply wire due to bad connection to ground. Had you got opportunity to also check compontents I mentioned before? (like C17, C18, T1, T2)
I see in logs old data from 2023-11-26 and later from 2024-02-12. Seems like this is data with old setting and now datalogging is disabled. Please make sure that you have enabled data logging. If you are sure, please share me your utcomp settings file, I'll take a look.
