MS3PRO vs AEM UEGO
 
hey guys, long time lurker here with a question. i got my ms3pro and my uego came not too long after. do i have to use the accessory port to wire the wideband into the ecu since the narrowband is only a single wire? which ports on the accesory plug would i have to use?

you can wire in through oe wiring or through the accessory port on back. your choice. documentation outlines both approaches, just read it and pick one

Do you have the AEM X series uego? That one has a positive and negative (ground) signal wire. I believe most other widebands just have a single signal wire.
That had me slightly confused when I installed my AEM X series. My OEM o2 plug is only one wire too. Therefore I just ran both signal wires to the options plug. Analog input and sensor ground, I think. I have the MS3 Pro PNP as well.

i believe it’s the x. whichever one lars sends with the mk. it has like 4 or 5 wires coming out of it.

i’ll be installing the ecu this weekend and just tuning narrowband for this week but next weekend i start turbo installation. the wideband looked very complicated and the factory o2 is 1 wire which had me a little confused. ill probably opt for using the accessory port so it will be direct and smooth. i need to look around and see how exactly to make the wideband talk to the ecu through the accessory port
