No A/F Readings for my new U7194, 9r08

Can not get any A/F readings for my new Predator. A/F Only reads 14.75 and does not change. Therefore, the DSLogRedux Program will not work either, because it requires the A/F readings. Manual 2008 Corvette application. Any help? Thanks

yep, at normal part-throttle driving/cruising, the AFR will always be 14.75, that's the stoich value that it needs to keep during part-throttle operation... which is what the fuel trims (ltft's) are used for... it uses those values to determine how much fuel to add/subtract in order to keep that AFR value at 14.75....
so, you're fine man... it's working...
when you go WOT, the AFR will change.... will drop down to the 11's, and 12's...
