Datalogging AFR doesn't work, everything else does
I'm running uberdata 1.7 on a P28 ecu. I can datalog everything great, except for my AFR that I am feeding into the ecu via LM-1. I get junk numbers usually between 8-10 and it just jumps all around so I know it's crap. I am running about 15.1:1 at idle. Any ideas why this is happening? The chip was burned with closed loop disabled, I have it tapped into D14 on the ecu.

Re: Datalogging AFR doesn't work, everything else does
i never got my LM-1 to datalog right either. I tried EVERYTHING that ANYONE told me and nothing ever worked. You do have to program the analog outputs on the LM-1. I was told to program them to
0v 7.39 a/f
5v 22.09 a/f
You can try that, heres a link to a post I put up on Uberdata forum, info that other gave me http://uberdata.pgmfi.org/forum/index.php?board=5;action=display;threadid=3373
