hello first of all apologize for my english. I am Spanish and I don't get along with the language

I can't get the RR loger to read me the AEM AFR connected through the COM port

I use the puggin but it still doesn't work. In the aem marker, if you see the port, it is well configured as the manufacturer marks.

What could be what I am doing wrong any idea? Thank you very much in advance

double check the wiring first and make sure u have proper ground and power and also wired up your usb to serial connector properly. aem is very easy to get to work in RR... see also here->

Yes, a few days ago I read your post that is why I decided to ask for help because it is not very simple I do not understand why I can not read rr

your ground wiring doesnt seem to be in order. why are you not running the ground from the AEM like its shown on the instructions? I can only see that you are wiring the blue wire and where does that brown wire go to? wire it exactly how the diagram AEM instructions show.

The brown wire is the ground wire, it is connected as required by aem. but I still can't read. there is some other. way to know if my pc is connected with afr. without being in rr?

Thx friend

Did u splice the ground to car ground?

Yes. this is how it is done

In this video you can see that if it is sending a signal through the com port

problem solved. the manual tells you to connect one way. but it does not say anything about whether the connector is female or male. my cable connector to pc is male. but of the aem it is female. I leave a picture of how it should go



thank you very much for the help friends

glad u solved it. never thought of that obvious connector type difference....its usually the stupid things that get u...
