Which one in should i trust basically LOL. Ive done free air cal twice and the lc1wb in link doesnt match what im seeing on the gauge. Now ive got afrest,lc1wb, and the actual gauge all reading differently LOL. I know how to get afrest and logged wb to agree just unsure why the gauge is saying different. Its just slightly off, less than 1 but its irritating. The gauge reads richer (lower #) than the logged wb signal. And yes, i have both signals 0-5v, i set that up a long time ago. Both the gauge and ecu are gettign true wb 0-5v signals. Should be the same
 
Thanks, sorry it took awhile to write back. Sno, so what your saying is basically my gauge is the one reading correctly and link needs to match that? If so then ive def been tuning my car way rich. I dont remember having this problem before the new turbo,fmic, and 272 crowers.... Im going to check my ground for the lc1 again but aside from taking it to a shop i would like to know which one to trust. My gauge shouldnt be able to change at all, its a static device that interprets 0-5VDC and outputs a number. That should be set at factory. This could be more of a problem than i thought...
I have to go through every mafcomp all over again after this is resolved. Fun, fun
