FJO CWC0002 Serial Logging

To save myself the trouble of running the 0-5v output to one of the pins in my ECU, I attempted to run my FJO CWC0002 via serial logging. According to the support section, this controller is supported for serial logging. I am using a serial-USB dongle and the FJO software can open the COM port and log AFR just fine (this is what I ended up using to log AFR). However, eCtune does not seem to see the voltage change. When serial logging is enabled and FJO selected from the drop down, it can see the COM port, but the voltage is a constant 3.9v (or something like that, whatever 17.6:1 afr is). I know that it is pulling thru the correct COM port because it locks out the FJO software. I am going to wire in the 0-5v output this afternoon so I can finish this street tune. I just wanted to share this experience incase someone else is having the same issue, or if someone has found a solution for this, please share!

from FJO software it works? We can debug to fix it:)

Thanks Calvin, Let me know what you need from me. I can do remote desktop and you can pilot if that is the easiest solution. I summed up the situation fairly well in my initial post. FJO PC software works, I can datalog with it, watch real-time...etc. If I first open eCtune, enable serial logging and connect, there are no error msg's or warnings. During this time, if I open the FJO PC software, it displays an error screen saying COM port in use. This leads me to believe that eCtune is using that COM port, just not using it correctly. Again, FJO CWC0002 with NTK L2H2 sensor.

That means ectune is using the correct port if FJO can't use it.. next week we will debug and see where it goes wrong.

Thank you. Let me know if you need anything from me.
