I just installed a AEM 30-0300X UEGO and it is not working correctly. The afr reading barley moves on Kpro, even if I rev. The AEM gauge moves like normal. Changing offset does change the afr on kpro, but still barley moves.

I selected PLX M Series. Soldered the white wire on the gauge to the ELD wire on the harness. I only extended the power wire a few inches. Ground to the body.

why don‘t you use the digital output? You need a Kpro v4 though.
Have you configured your ECU correctly to read using the analog ELD input?

I’m new to kpro (only used flash pro in the past). How do I set up the digital output?
I do have kpro v4.
This is how I have it set up currently (22:35-23:50 mark In the video)

sorry, only read PLX. If you get the PLX module with a directly supported digital output.


This works a treat on a KPro V4. Friend has one I setted up. Connect single digital line, select and go. Zero calibration or offset work.


For the AEM one seems to have to do some signal conversion, i.e. convert from a +-12V RS232 to a inverted 0-5V TTL signal.

For you problem, I could only guide you though fixing this.
Have you checked the voltage of the analog output?
Does the raw ELD voltage read the same?

I ended up using the analog inputs for signal and ground. Works perfectly now(y)
