You definitely need to adjust it with hand-calculated data. My scangauge has a 7-8% correction factor, even with near 0 long term fuel trims.

Will read-up on the procedure, thanks Charlie. I guess changing the AFR sensor screws it up to this degree... As I recall with my SC2, on my MINI Cooper S, I was able to tweak or fudge some settings like vehicle weight, displacement, something else, such that on fill-ups, adjustments were really not needed. It took some playing, but I was able to get it very close to where it became set it and forget it... Hoping to refine the UG to the 4Runner like that, at some point.

I get 15.7 in mixed driving, less now that I don't drive to work 12 highway miles away..
Even the little lady's 5.7L sequoia beats it! It gets 16.5 in mixed driving, plus 200 more HPs and torque, arrrrrrr.....

I have a 98 T4R with just shy of 500,000kms original everything, and I seem to get around 550km to a full tank with about 75% highway and 25% city driving. Pretty happy with it so far im sure lift and tires will change that drastically haha

Watch your tire pressures too. My mileage had gone from bad to worse (~14 down to ~11/12ish) and finally realized I had only aired back up to around 25lbs last time.
Did ~120 miles of forest and logging roads this past weekend, mix of 4hi and 4lo, running `17lbs, carrying way more crap than needed. Got just over 9mpg.

Usually if you replace your fuel air sensor and your 02 sensor and clean the mass air flow it will make a pretty big difference and it only takes like 20 minutes. If you have torque pro and a Bluetooth scanner you can test and see if the sensors are still operating withing factory spec

2002 Sport here and I decided to calculate my mileage for the first time today. I've owned the rig for about a month now.
Ended up doing 288.7 miles @ 17.4 MPG...which surprised me after hearing about the terrible mileage I could expect. Not that the number is fantastic mind you, our Honda Odyssey can do nearly 30 MPG if we have good weather and a long stretch to let cruise control do all the work.
So far, most of my driving has been 10-15 mile trips on roads that let me do 40-50 MPH while hitting a stoplight or two, a handful four-way stops and the occasional round-a-bout.
I won't track every tank, but I will try to gauge some highway mileage later this summer.

Armored double cab taco, 4x4, at, 4.10s and 35's. 3.4 supercharged all stock otherwise gets a very consistent 13.
Nearly stock 4x4 2.7 with 3" of lift and multiple tire setups will get between 10-12 mpg depending how I drive.
I don't drive like a jackass, don't speed, just basically cruising back roads at 55ish most of the time. I just don't believe anyone who claims 17+ on a built rig, I've had a lot of these trucks, only one that would do that much was 2wd, 2.7 5 speed, 3.73s and 235/75r15. Hypermiled to 23 mpg once, but typically did around 17.

Your welcome Tony. I went through the whole 9 yards of calibrating mine. Calibrating the distance, calibrating the fuel economy over the course of 4 tanks, etc. There is an anomaly that I haven't taken the time to figure out yet. After calibrating for distance traveled it corrected the mph of the gauge to within 1 mph at highway speeds (cluster shows 70 and gauge shows 71) but my trip mileage on the gauge will be about 4% higher than the cluster trip mileage. Kinda strange and probably skewing my mpg's on the gauge slightly higher than reality. If I find time I'll recalibrate the distance and mpg's again. If you decide to calibrate yours it is recommended to calibrate distance before mpg's.

Edit: I might try using a gps app to calibrate distance traveled which changes the mph on the gauge. The recommended way in the instructions is to use a fairly straight highway, start at a mile marker and then drive to another mile marker x miles down the road and stop at it. It will ask how many miles you went and then adjust accordingly.

I get about 16 on a normal tank, and 18 if there’s a longer trip mixed in there like 2.5 hours round trip. This is with a 5 speed, 33s, and manual hubs.
I got 20 on an 8 hour trip but that was with the auto trans and no locking hubs
