temperature vs mpg

[lunarhighway]

Most people here will be aware of the impact of temperature on FE but do you actively compare the temperature to your FE?

since i'm useing tank to tank fillups as my only reference, figuring out if a certain mod is working can be something of a gamble....
i need about a week and a half to run trough a tank and like to use at least two tanks before drawing carefull conclusions, but by that time a lof of weather changes might have occured
sometimes you get the feeling your on your way to a record tank, only to find out at your next fillup things wheren't as good as expected... in the past this got me frustrated but since i plotted a temperature graph of the average monthly temperature in my area next to my fuelgraph a different picture unflods...

temperature has a big impact on my fe and a drop of just a few degrees can cause a serious dent in my FE graph... but it also means i shouldn't beat myself (or a recently installed mod) up over it... not if the drop in fe corolates with previously refistred FE/temp relations

i just mention it, as being aware of the temperature impact can be a good thing while evaluating certain mods over a longer time. especially if you haven't got the time and equiptment to make more reliable assesments.
