Re: the OP's question, it should read 9999mpg when you are DFCO'ing.
And it's an 04 focus. It'll have DFCO. My 92 civic had it and my 04 yaris has it.
MisterJeeves,
You say you get better mpg (than DFCO) in neutral. That sounds right. You will coast further in neutral than DFCO. You, with a 2.3 litre, would experience savage engine braking while DFCO'ing. This loss of speed would have to be made up at some point with the resultant loss of mpg. Coasting would use fuel while doing so but there would be a net saving over DFCO. This being a point often overlooked (deliberately?) by the hypermiling detractors.
But for now just make sure you calibrate your SG2 as best you can. After that, just enjoy the feedback it gives. What fun eh??
