Well, it has been running nicely. I've been trying to figure out how to get the best economy out of it. That's frustrating. For the last 2 weeks, I have been running on the "stock modified" tune. That seemed like it was doing alright. But, when I stopped to fill up last night, the trip odometer indicated only 417 miles driven, for a mpg calculation of about 13.5ish. I could have sworn my last fillup was 500 miles ago by my memory of the odometer. So I wonder if there is an issue with my trip odometer (electronic). I'm pretty sure I have seen it zero out on it's own a couple times in the past without me pushing the button. Anyway, if I had driven 500 miles over the past 2 weeks, that would give me 17mpg. That's better. Not what I want, but better. For the next 2 weeks, I'm going to drive with the tuner bypassed and see what happens. I also wrote down the odometer reading when I zeroed the trip odometer, this time.
In other news, it started up on the first try this morning in 15 degree weather. It was a bit sluggish (batteries aren't exactly new) and took some extra cranking. But I did NOT have to recycle the glow plugs for a second try. That seems pretty good to me. I just got home from Lowe's where I bought a wifi switch/ timer thingy so I can plug in the block heater and schedule it to turn on about 3 hrs before I need to leave for work in the mornings. That should be the ticket to perfect cold weather starts.
