So kind of a weird problem I have developed the past couple weeks. My AFR will display incorrectly in MSDroid. But, sometimes it will display correctly. It almost seems as it heats up (or the longer I stay connected) the richer it gets. But, this only happens in MSDroid. On my digital gauge for the MTX-L it is dead on. I even replaced the sensor with a new one and calibrated it, just to remove a possibility. So I'm trying to figure out what it could be. I have been trying to get Tunerstudio to connect to my laptop via the rs232 bluetooth module I have, but I can't get it to find it. I want to make sure the calibrate afr is correct, but I haven't changed any setting as this was happening.

Any idea on the the afr issue?
