    Logging PLX wideband AFR with Evoscan

    I know it is outdated, but maybe just FYI, I used an Arduino to convert the PLX wideband AFR to AEM protocol, so that on the EvoScan can log as AEM AFR data. To do that, assuming you have experience on Arduino, and if now, it's better to google or youtube for tutorial because it is actually very simple.


    Hardware:
    normal 3.5mm headphone jack plug
    Arduino supported board, eg, I use ESP32 dev board which is cheaper and faster.


    Software:
    Arduino IDE.
    EvoScan, I am using latest v3.1




    This 3.5mm plug is used to plug into the PLX control box. The "tip" is the data, and the "bottom" on the plug is ground. So, simply connect the data into the RX of my ESP32, and the GND of course.




    After that, connect my ESP32 to the PC USB and then select the correct COM port from the EvoScan by "WideBand(WDB) -> Select Wideband Serial ComPort" and also select the "AEM UEGO 115200......." as the AEM device.



    After all this, then can happy logging!After all this, then can happy logging!



    Thanks.

    I did it a different way - I used the 5v output from the PLX and put it into an unused ECU input and then logged that with Evoscan. I'm not doing that anymore as I have a link ecu.

    That means using onboard ECU ADC function, right? But would that slow down the MUT2 speed because of one more ID logging? Anyway, Link ECU is much better I guess.

    That's over my head I'm afraid!
    @foxdie can you answer that?

    Just change to use even smaller board, and it's enough to do the conversion.
