Trying to figure out how to hook up my AEM wideband to datalog with the s300. I have the factory O2 along with the AEM unit. Here is what I posted in another thread but gained no response:

s300 knowledge informed people, please help!

Trying to hook up my AEM wideband up to the s300 in order to datalog the readings from the wideband. Now, I understand that the AEM requires a 0-5V source in order to work and read properly to the s300. After reading on Hondata's site, I have what I think is correct for wiring/hooking up but I wanted to make sure:

The wires needed for datalogging are the Blue and White wires. From what I gather from Hondata, the WHITE wire will go to the ELD input on the ECU which is pin D10 on any OBD1 ECU (mine is a P28). The BLUE wire, according to AEM, "connects to a RS-232 com port for hyper-terminal datalogging." I am not quite sure what, or where, a RS-232 com port would be on my s300.

Anyone every dealt with this and able to lend a hand in order for me to get the AEM WB hooked up to my s300?

TIA!

 

Leave the blue wire alone. It's not needed.

 

Okay, so just white wire to the D10 pin on the ECU? Sounds too simple. Can anyone confirm?

TIA

 

^ Yes, it's that simply and don't forget to disable ELD in the s300.

 

Will give it a shot. Under what menu is the ELD options? Sorry, I am no tuner and have not really dug through s300 in depth enough to know where everything is. Just trying to get car wired up and driven to exhaust shop on partial tune that I have at the moment after a install/purchase of new exhaust, intercooler and piping.

TIA for your help

 

if you use the eld, you have to remove 2 resistors in the ecm, that is covered in the hlep section in smanager.

i have mine setup this way as well, and it works fine!
