Do not use D14 as it cannot see the full voltage rannge.

D10 is the best input to use: http://www.hondata.com/help/smanager/wi ... b=wideband

Again thank you Spunkster for getting back.


After checking my ECU most of the pin outs I can't use for some sort of reason

D14 is out because as you mentioned it doesn't supply enough voltage
D12 is out because I don't have anything is C42 on my ECU
D10 is out because I have R136/R138 filled and I'm not going to touch that
B6 is out because I have R2/R3 filled and again I'm not about to touvh that

I do have v3 can I use the Analog cable that came with it? They say they supply 0-5v but again I"m new to all this so there may be something I don't know/understand yet.

Thanks again

D10 can be used, you only need to cut one let of the resistor, it can be re-soldered later if you want or need to.

Just cut the resistors and use D10. It's super simple.

Thank you guys. I will find a small pair of snips and give cutting those a shot.

Alright so I wired my wideband wire to d10 and changed it on the close looped advanced but when I datalog, the afr bounce from 13-14 really fast and even when the gauge went to 10.0 the data logs are somewhat just stuck bouncing between 13-14 afr

Post your calibration as well as a datalog showing the issue.

Post your calibration as well as a datalog showing the issue.

So as i was looking under the dash the the blue wire was connected to the ecu instead of the white wire so i am going to rewire the wideband to the ecu and re test it to see if the problem goes away

Fixed the problem it was the wiring after all this car was wired 3 years ago following aem’s instructions using the blue wire and after reading you have to use the white for the computer to read it properly
