AFR doesn't read on tuner studio or megatune
Posted: Wed Apr 01, 2009 7:36 pm
I have MSII v3.57 2.888 code assembled unit. I have a LM1 wideband in the truck for a couple years. Problem is when I am trying to tune the squirt the AFR will only read about 12.1:1 the DB gauge I have installed is reading properly. I hook up the stim and same thing can't get the AFR to diplay anything but 12.1:1 and it glitches to 16.9 or 14.8 somtimes. I go into the real time display and the EGO volts 1 and 2 are going from zero to five volts like they should but it isn't interpreting to AFR or lambda. I have it set to wideband and have the wideband chosen as LC1. I have tried all kinds of other widebands and they still will not display on hte stim. Truck starts and runs fine just had to tune with zero O2 to watch. Any help is appreaciated.
I can wire and get a MPI system running but miss the easy stuff. 
I will try it tonight. Thanks again.
