Last night while watching the logworks 2 virtial gauge on the laptop it did not agree with the reading on the XD-16. It was consistently about 1.5 A/F higher that the XD-16. If the 16 was reading 13.5 log works would be reading 15.0 or so. I made sure it was selected for gasoline (14.7) Am I doing something wrong? Which one do I tune by, or should they be the same. Any ideas? Thanks
