It was day 2, so maybe it will drop back down after adaptation..

Went to the beach yesterday, continuous driving around 75-80 mph for about 100 miles. I don't think it's unheard of on the highway. I was just happy to see improvements from v1.22. My first version JB3 got me around 24-25 mpg

hun77777 · 06-01-2009, 04:58 PM

depends on where you drive and how you drive... 25+ mpg won't happen in NY metro area no matter how hard you try, but on interstate/highway trip, people get 30+ mpg time to time... I managed to pull 500+ miles on one tank couple times with procede...

This is true. I'll be happy if I see 17-18mpg.

Right now I've been averaging about 15mpg.

definately not unheard of. i do alot of highway driving and "IF" im doing 70-80, I get around 27-30mpg. At 90mph, I get around 25mpg

cu_north · 06-01-2009, 05:42 PM

Average MPG in limp mode?

Driver72 · 06-01-2009, 06:39 PM

Oh by the way, I think it's pretty common sense not to go off the onboard computer either. The ONLY way to check and know gas mileage is to simply fill up and do the mileage divided by gallons method.
All else is irrelevant and pure speculation on the computers part.
Note I have seen some of these on board computers be within .5 mpg of accuracy to what you really got, but on the next tank I've seen it be 1.5 mpg off too.
They are based on the mileage you've driven and purely estimating how much gas is left in the tank based on the sensor in the tank.

WhiteSled · 06-01-2009, 07:22 PM

before we say xx mpg with xx tune....you guys realize that these tunes make lil to no changes during partial throttle farting around right lol

skitlz · 06-01-2009, 10:15 PM

hell, mines hovering around 23 mpg.. i drive with a leadfoot most of the time going through towns,, but i do have a little highway commuting that i get in the mid 30s.. so it balances out

but i did at one time before a battery reset,, or maybe it was for warranty work, but i was up to like 26 average from a 2000 mile roadtrip,, go go 38 on the highway

darkphantom · 06-01-2009, 11:24 PM

lol, maybe you have the wrong 1.3 because my foot doesn't let off that easy...

I don't buy it. Sure you're not looking at the avg mpH? I did that once after resetting - clicked to many times.

AV9 · 06-02-2009, 04:08 AM

i get 22.4 mpg max! like it wont budge over that point at all...this was before and after my jb+ install

Brianbmwboy · 06-02-2009, 09:42 AM

I still have 1.22 in my car and get around 30 mpg all the time driving 70-80 on highway nicely. Rallying hard around town in around 17 or so. Considering the performance i'm pretty darn happy.

Jimspeed · 06-02-2009, 10:11 AM

I just drove a 700 round trip.

Avg gas mileage with BMS DCI and JB3 v 3- 29mpg.

Avg speeds at 59 mph (combined highway and city, mostly highway)

e92man · 06-02-2009, 10:17 AM

WOW thats impressive. I do mostly city driving and can't seem to get over 19 with my jb+
