Hello,

Since I have my jb4 installed in my bmw f30 328i, I have noticed that the instant fuel consumption indicator (MPG in US cars and Liters/100 kms in mine EU car) indicates very high levels of fuel consumption, even at very moderate throttle inputs. Is it possible that this information showed are not real because I have the Jb4? Maybe because is an EU car? It also happens in map 0.

Thanks for your support

Have you manually verified your mileage?

I found on my 535ix on map 5 if I keep my foot out of the go pedal my mileage actually went up. Toughest part is keeping a light right foot though.

Sorry for my late reply.
I have checked my real consumption and it's almost the same that without the jb4. Just the indicator seems that it is not accurate at very lo throttle pedal inputs.
