Been recording my fuel consumption since I got the car from new
Had a remap and have noticed the fuel consumption hasn't really improved but the trip computer mpg is now consistently over reading (averaged over 38 tankfuls):
Pre remap
Trip computer 43.95mpg
Calculated 44.58mpg
Post remap
Trip computer 48.95mpg
Calculated 44.81mpg
That's a +4mpg error post remap .
Attached a graph for those of a certain persuasion!
Now I'm not moaning cos I love the remap and does exactly what I wanted.
Calculated values come from pump litres and trip odometer reading. Before anyone suggests, measured the trip odometer against google maps and it is considerably accurate less than 0.5% error.
