Hahaha I've been procrastinating on the fuel log because I really don't want to keep track of E85 vs. gasoline...I'll run this tank down to empty and do a full tank of 91 to keep the "accounting" easier. With a consistent gas/ethanol blend a fuel log should be a little easier.
Today I drove to work on the modified intake timing map, and results were good! 60mph cruise was averaging around 42.5mpg. I tested 65mph and the mpgs were still pretty good at about 39.
I then put the cruise control at 70mph and the mpg plummeted to a tad over 36
I took a glance at the MAP reading and unfortunately it had gone down to only 7.5psi despite the 0.4g/rev load (for comparison, it was around 7.5 at 60mph when the load was just 0.33g/rev). I may need to dial the cam back a little to allow more EGR flow at 3000rpm. Need to think more about this...
Speaking of aero, this car actually has quite a bit of room for improvement. A bellypan and diffuser would drop the drag another 10% or so, the ride height could be lowered a little more, and the mirrors are HUGE, but I'm probably going to sell the car after a few years so might as well keep more things stock.
