Hooking up AEM UEGO to EGRL pin

Hello Hondata or anyone that might know. I've been trying to hook up a buddies wideband to his S300 for logging and possibly closed loop operation but I cant get it to read properly when I hook it to the EGRL pin. It just pins to 18AFR when I go WOT and it's all over the place at cruise. I tried the voltage comp table and the voltage offset value but it's not working. Is there any pin that I can use that will allow a straight hookup without any issues? And I see in the voltage offset table that I need a cpacitor on C24. What the hell is that? There is no pin C24 anywhere on the ECU. Thanks.

He's running a B20 non vtec motor in an EG hatch. It's turbo as well. But that really shouldn't matter when hooking to the ECU.

It's not C24, it is C42. http://www.hondata.com/help/smanager/an ... ghtsub=d12

What UEGO displays at this time?
Sounds like you have broken O2sensor.

The gauge reads perfect. Its' brand new. It just doesn't get translated properly by the S300. I tried the ELD and the car wouldn't even start. I don't know which ECU he has but none of the inputs work,

Output from UEGO has 5 program of signal. Do you set output to P0 or P1?
