Hello, I use a AEM UEGO wideband gauge in the O2 input. Everything is OK , but I know that in the ELD input the voltage is not the same between the gauge and the ECU ELD input. (matter of current??)

But if I correct it with the voltage offset, is that accuracy what I will reading? Because in this case, I could connect the stock narrowband sensor to the O2 intput to use the closed loop and datalog the AFR through the ELD input??

Thanks a lot

You cannot use a wideband input to run a car in closed loop. It will not work. I only recommend the PLX devices wiedeband because it has both wideband and narrowband outputs to allow you to run the car in closed loop with the narrowband signal while still sending a wideband signal to the ecu for datalogging.

I am running my AEM through the ELD and have to use a voltage offset to correct the reading. I have to use something like .78 to get the gauge to match the datalogs. But I use my stock O2 sensor for the closed loop stuff. Just weld two bungs into the exhaust system.

Ok smracing, so you connect the O2 as normal and the AEM wideband to the ELD. So when in closed loop, it's the O2 sensor who work to achive the narrowband information for the closed loop?

I have already two bungs in my exaust to connect the stock sensor and the wideband.

Thank you Spunkster, I really wanted the PLX but I'm located in Switzerland and wenn I need to order something, I must order to the same dealer all my parts. It's the matter of delivery cost.. and my Dealer, Kingmotorsports, had no PLX to sell, only ther AEM...

Thanks

Yes. The narrowband operates exactly the way Honda designed it to.
