RomRaider

I purchased wideband few days ago, i want to log it with other parameters to tune the engine. I used AEM's serial output to serial/usb adapter and with usb to pc. I tested serial in PuTTY, and it works fine, reading AFR. But i just can't make it work with romraider logger. Values are constantly zero (0). I'm getting to a point, where im gonna throw my laptop as far as i can .

Please helpp

Are you logging the ECU at the same time, or just the AEM?
If you want just the AEM, uncheck ECU in the top toolbar.

You can also submit your rr_system.log if problems persist.

Here it is, sorry it isn't clean log as i was trying all kinds of things. But yes, i did uncheck ECU box for logging just AEM.

All I can get from that log is the you have both:
20:15:47,380 ERROR [AEM UEGO Lambda [19200]] - AEM UEGO Lambda [19200]: connect error
20:15:47,822 ERROR [AEM UEGO AFR [9600 baud]] - AEM UEGO AFR [9600 baud]: connect error

defined to use COM3 and that you are trying to log both at the same time through the same port and getting the error:
com.romraider.logger.ecu.exception.SerialCommunicationException: Port is currently in use: COM3

Click the Un-select all button and choose only the correct AEM external item.
