Smarty Mileage Report

1665 23
I thought some of you might want to see some mileage numbers on a road trip.

Denver, Co to Elgin, Ok via I-70 to I-35. 758 miles total running 80 mph through Colorado and 75 through Kansas and Oklahoma, and then 80 mph again for the last 55 miles. Setting on SW 7 and default on all other settings, 19.1 mpg.

Elgin to Denver, used Hwy 287, which varies from 70 mph to 75 mph and stops through towns along the way, same Smarty settings, 19.5 mpg.

Obviously these are approximate due to fill up discrepencies. The motor had 9700 miles on it when I left Denver, so I don't think the motor is quite broken in yet, so we'll see if there's any improvements next time.

With the 12 ME I have noticed 19.5 mpg on a 450 mile trip avg. 72 mph. At 78 mph 18.5mpg. Boost seems to stay near 6 lbs and 600-700 egt on flat ground.

Running empty with Original ME on SW5 Timing 3 and all others default. I was getting 21.5-22 at 75MPH.

Same run same setting 12ME I am down to 19mpgs. This was measured today over 485 miles.

I am thinking about reloading the original release. Seems to be too much boost just cruising at speed.

Just to be clear is all these MPG numbers hand calculated? or what the overhead is showing.

Mine are all hand calculated. The overhead usually shows 23 mpg and seems to be roughly 3 mpg off of the hand calculated mpg.

I must drive really hard or something because my numbers are not even close to what yall are getting. Or maybe I have not re-cal the tire size correctly. But my fuel tank is between 1/4 and empty right now and I only have 380 miles on this tank. On average I am getting 13mpg on each tank. I did however lighten up on my driving about 5 tanks ago and got 15.2mpg. It has been like this pretty much with any software version. So what are yall doing different from me. my overhead shows 14.5 right now.

I'm also amazed at some of the mileage you guys are getting. I'm running Smarty ME and just upgraded to 12me. Best I've seen so far on the highway is 17.5mpg on the overhead which is around 16.5 hand calc'd. I have 3" lift, 35" tires and a lumber rack, so that's probably costing me 2-3 mpg, which would get me close to 20mpg. But it's just amazing to see guys with lifts and big tires breaking 20mpg.

Mileage has definately improved by 1-2 mpg and so far it looks like 12me is about 0.5mpg better than the original release.

Mine are hand calculated and cruise is set while on the Expressway. I am reporting strictly my HIGHWAY only mileage.

Overhead is usally 2 or 3 mpg higher.

Are you getting those MPG #'s with the truck in your sig (Rize 8" w/ Skyjacker leafs -- 20's on 37" Toyo's) ??????

I'm not calling B.S on ya, but I think you made a mathematical error in your calculations if you got those # with that truck!!!

12me tune

setting SW9 all defaults except RP #3 70-75mph 20.7 MPG

This new program :wave:

Leaving on SW9 for now as daily driver. Spools even better, EGT's still in check.:thumbsup:

Good catch!!! :doh:

My bad, I have failed to update my sig since taking all of that stuff off, lol. The numbers reported are on stock wheels and tires with a level kit.

The numbers are hand calculated too, for the guy who asked...

I was sure something was wrong!! Your lift looked really GOOD, but they really screw-up the driveability and become a PIA after the newness wears off...
