JB3 1.11v mpg

i2iSTUDIOS · 12-14-2008, 10:17 PM

I did a round trip run today, got 29.7 mpg at an average speed of 69mph in some pretty high winds.

I am running the default map.

glad to see the tune hasn't hurt the mpg much.

It doesnt hurt mpg per say, but it does overinflate the displayed mpg number on your screen...

+1, you have to calculate mileage the old fashioned way to know what you're really getting because the new 29.2 compliant tunes fool the ECU into thinking the fuel pressure is lower than it really is.

I dont think that counts for normal daily driving, from what i know the JB3 barely is doing anything during normal driving. If or when your reset your trip odom. if you dont go WOT during the trip, i think the numbers will be pretty accurate.

Yea, when pushing the car it really effects the mpg.

maybe, maybe not, only way to know is the old fashioned way, otherwise you can just trust the computer to get that warm squishy feeling inside.
