i have the 1313u box with the aem wideband. i am running JUST the wideband in the stock location after the cat. for some reason i cannot get a reading for a/f. i tried calibrating it. i tried a different wideband. if gain is at 1.27 it reads like 18.xx a/f and a maxed out 5v. i can change the gain to .79 and that gets it to 14,7 and 3.9v, but it doesnt change. i checked the wiring from the box to the o2. im stuck!


ANY IDEAS?????

thanks
