In fact, the mileage you're getting is pretty much what I would have predicted at that speed based on my own futzing around:

Note that this was taken in warm conditions, pre-XFi cam and pre-Swift transmission. The fact you're getting 43 mpg (US) in the cold, at those speeds in a heavier, less aerodynamic (probably) convertible, tells me your mods are helping. |
Wow, that graph sure puts it in perspective!! (excellent work)
43 was our best in warm weather(sans XFI cam), on the last tank with XFI Cam we got 39-40mpg, in Temps -5 to 0C. With the top up and the extra 150lbs, I can't see it being that much less aerodynamic..its a pretty sleek little rig. But I have no way of confirming this. So from your graph, if we extrapolate, the FE we're getting is as expected.. around 40 US Mpg at 110kph..eh? (Especially with that conv tranny! Grrr)
Well that is re-assuring though, though we'll keep pressing for better. I'll be sure to post more updates on the car
