Tuned 2.0 Fuel Economy *pics*
Tuned 2.0 Fuel Economy *pics*
So this weekend I went for a drive into the mountains with my girlfriend to Banff, AB.
The trip was 599kms (372m) round trip and I did it on 1 tank! (see pics below) For about 500 of those kms I was doing 120kmph (75mph) and the rest was bumming around Banff in second gear because thier speed limit is only 40kmph (24mph)
My mods are 2.8 60# injectors, exhaust, etc.
So here's proof of what a tuned lsj can acheive
*notice how I still have 1/8 of a tank left!!
6.0L/100km is 40mpg
Before I got into the city I was averaging 5.7 which is around 43mpg.

Thanks!
I'll admit I was really impressed.
My car is tuned. If I keep my foot out of it, it is amazing on fuel.
Keep in mind too, at that average hiway speed is not even the optimal speed for fuel economy. The general concensus is at 100kmph (60mph) is the best for fuel economy. If I had of done that I would be close to 50mpg!

Wish my 08 would show tenths on the dic......only get whole numbers when on inst on metric
I hope you calculated this yourself, and didn't use the cars algorithm. It won't take new injectors into account, so it thinks you're burning less fuel. You did pick up quite a bit for sure though.
You can get close to this without a tune of any kind. I had a trip from Edmonton to BC last year where I averaged 6.2 L/100 km. I also was far from babying it with speeds around 120 km/h being the norm. Very, very rare that my car is over 10 L/100 km though, except in the winter.
I'd love to see what I could average with a good tune!

I get like 27mpg-ish, with a good amount of it being WOT; likewise, babying it, I get like 30mpg, so It's not even a big deal to me.

Ever since I got my CAI, it seems like it guzzles gas more, but whatever.

heh, yea these puppies can get real high mpgs. coming back from the hamptons on a hot summer day last summer, cruising at about 65mph with the a/c on, i managed very high mpg. i reset it the moment i hit 65mph, set the cruise, watched it fluctuate between 43 and 38 and the final average when i reset it, before slowing down as i didn't want 99.9 or infinity mpg averaged in due to coasting with no fuel, was.... 40.4mpg!

just took a trip to florida with some friends, so with me, plus 2 other people in the car and a trunk full of luggage i was able to get about 31 avg on the highway. but i set the cruise control at 75. not too bad if ya ask me. i usually get about 26 around town.
