Hello I recently added to my collection a 89 ef with a gsr swap
B17 block
B16a head
Rc370 injectors set at 310 on hondata
Skunk 2 fuel rail and timing gears
I’m trying to make sure I’m within parameters the motor is running amazing no knocks or burning oil or leaks “knock on wood”
I can’t seem to find my air fuel ratio in hondata as I have one in my car it just doesn’t read anything just lines come up so I’m thinking that I need to wire that in or I’m missing somthing I have an air fuel parameter and it just tells you if it’s rich or not idle is amazing after warm up I’m going to attach some photos after running for 20 min
Any help would be greatly appreciated

the wideband needs to be wired into pin D10 on the ecu, and then programmed into the map under the closed loop tabs in parameters, and disable ELD in the misc tab in parameters. (D10 is normally ELD input)
