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?"

A gentlemen in the FI section said to disregard the BLUE wire, pin WHITE to the D10 pin on the ECU and disable the ELD in the s300 menu. He may know what he is talking about but I just want to get confirmation before I go forward with this.

TIA guys!

Wire colors will be different, but the basics are the same.

 

Yes, I read that. I will not be using the AEM unit for NB readings as I am keeping the oem O2 in the car. So basically I disregard the BLUE wire and pin the WHITE to D10, correct?

 

I'd assume you'd just leave the O2 wire alone then. So just wire the wideband into ELD(D10).
