Morning all, I did some similair analysis on my vec c 1.9 cdti 120, as a new member I iwll publish similair results when i have a valid data set to compare, possibly around 10k miles of ownership.



The great thing with keeping this data is it flags up any issues almost immediately when you know whta your normal mpg is.



Due to commuting ~30k miles a year, fuel economy and comfort are two big factors that matter to me.



As a benchmark, my vec c did an average of 52mpg over the 3 years i owned it, i want the insignia to acheive at least 50mpg, due to it being a heavy car. If this is not acheived i will look at an "eco" remap.



Updates to follow.....
