I went out tonight tuning and for the life of me, the logger isn't working properly with the AEM Uego gauge. I just tune using the gauge and not the logged values. They seem to be 1.0 afr off, even with the programming feature in Werewolf. I kept adding and adding and adding fuel to get it from 11.5 to 10.5, but it never seemed to leave 11.0, but the gauge was pegged at 10afr. I then said "forget it" and just had my friend drive while I took fuel away until the gauge read 10.2 and noticed that there was so much dumped fuel, I backed out from almost 125 VE to 89 VE just to get the gauge to read 10.3:1. Keep in mind, the logger was showing 11.0 when I was at 125 VE in the boost ranges. The car pulls so much better and the knock I was getting was rich knock from adding so much fuel as per the logger. The gauge is right.
Now, I have my Gauge output going into my O2 sensor pin in the ECU. When I plug it into the EGRt pin, it doesn't read in the logger or change at all. If I recall, the logger is supposed to read from the EGRt pin for the 0-5v output. Being that I'm in the O2 spot, I assume I'm reading in the 0-1v range which is why I think my logs are so screwed up. Any ideas? Remember, in the EGRt slot, it doesn't read, but does give a value.
