I have Utec.. And I got few logs on my computer from my car.. Question is.. Is there any way to get AFR from my car w/o getting Tuner Pro? I have 06 G35 Coupe.. I heard my car already have WB.. So.. I was wondering if I can get AFR reads w/o getting Tuner pro.. Thanks..

 

the only way you can check your OE WB is Cipher, and there`s no way that you could synchronize Cipher with UTEC logger tools, and its so hard if you`re trying to figure out the AFR by comparing the log on Cipher and the log on the UTEC.

and its being said that Factory O2 sensors isn`t that accurate when compared to Aftermarket ones, so get TurboXS Tuner and you`ll be fine.
