#24134, "afr gauge problem"


          

I have a digital afr gauge from gadgetseller.com. I put it in before I went turbo and it worked correctly. Ever since I went turbo, it does not seeem to work right. During idle/partial throttle, it cycles between .2 and .8 volts. That is good, but at WOT, it shows .1xx volts. This means I am running really lean, but this isn't the case. EGT's are good (up to 810 celsius), so this doesn't seem to be right. I checked the ground, it was good, but I relocated it anyway. I also checked the wire for the o2 sensor signal. I picked it up at the computer and it is very solid. I would say that maybe the gauge is just fucked, but it is showing reasonable readings at partial throttle. There is no way I can be running that lean, I mean my motor would be gone by now. I am trusting my egt on this one, but I would like to figure out what the hell is wrong with this thing. thanks for reading this guys, justin
