Wideband O2 Sensor questions.
 

I just picked up an EcuTek ProECU w/ RaceROM as well as an Innovate Motorsports MTX-L Wideband O2 sensor and gauge. I'm curious what folks experiences have been installing the AFR system and getting that information to the EcuTek for datalogging. I'm prepping myself for a Kraftwerks SC install that I'll do this winter when I store the car in the garage.

My main question is, is there any way to replace the rear O2 sensor with the wideband afr. I know with my Corolla the rear O2 sensor was only used for cat efficiency readings and wasn't really needed for the performance of the car. I'll soon be completely catless as my county in PA does not require emissions testing whatsoever.

Thanks in advance for all the help and input!

The rear O2 sensor input is the usual way to do it, if you look in the ECUtek help pdf files it will tell you what is needed. Its in the RaceROM help file which has lots of info on the GTR and BRZ setups.

Yep that's how most tuners do it if I'm not mistaken. You just make a custom map to convert voltage to an AFR reading and you can log that custom map output when datalogging.
