I have connected the wideband output of the uego to the yellow wire of the mapecu and the ground to one of the grounds of the mapecu. Have selected the AEM.o2 under mapcal configurations and all the mapecu is saying is rich it is not giving an actual AFR reading. I have followed the install instructions from mapecu so I know that the wires are hooked up correctly. Everything else is good. So can someone help me with why its only telling me a rich or lean reading and not an actual number. Thanks
