Currently starting temps have been around 30c so nothing colder until it gets near decemeber where it will get down to 0c
Still I went down to 110 at 30c to even out the fuel so its the same all the way though warmup
42.5mpg, best highway mileage to date. Pretty sure its because of the timing map as I don't lean out the fuel mixture, I just run at stoich or close it while driving.
