Any of you honda guys experience this? Engine is an 1994 acura integra gsr (b18c1).

This has been talked about in other threads (randomly). The mpguino measures the amount of time that the injector is open. More accurately, it measures how much time the injector gets power. If you lower your voltage, the injector opens a bit more slowly thus injecting less fuel for the same amount of time it is powered up. This throws off the calibration of your mpguino. I don't think it would account for a 3-5 mpg difference, but that is likely part of the problem.
