Programmer Milage

[Muddyrc]

Does anyone know how to figure out MPG? Stock I would be lucky to get 800kms to 160 liters (40 gals??) of Diesel. I bought a bullydog programmer and a AEM intake, then got up to 1000kms to a tank (160 liters). Now I got a superchip programmer and I am at 700kms to around 70 liters. I will be driving around 700-800kms tomorrow so I will se how much I get on a tank. Is this normal for a programmer?

No, those are not normal.

You should only see about 1mpg better, 2 if you are lucky and drive like a senior citizen.

Your first set of numbers are pretty low, the 2nd set aren't too great, but pretty normal for around town type driving. Your last set (23.5mpg) is possible, but not very likely IMOP.

This would all be for an excursion of course and not the expedition in your sig.

Thanks for the info. In the end I got around 1500kms to 190 liters. I don't know what the programmer does but it shows 44.3 mpg on my display. lol. I know I am not getting that.

What is the best way to record my fuel consuption? Go from a full tank or go by a certain amount of fuel?

I am not talking about the Expedition. But I am putting a Bullydog GT tuner in that one as well to see if I can get any better milage out of it. It is good on gas, as it has the 6 speed tranny. That's the wifes truck/baby carrier.

It doesn't matter how you fill your tank. Miles per gallon is a function of miles driven divided by gallons you put in your tank.

Once you install a tuner/chip, your over-head readout will no longer be correct.

if i do it by hand its really really close to the overhead

Do you have a chip or tuner installed?

[scagle1]

yeah , i wish mine was close to the 24mpg it says on the overhead. Even slightly close would be nice but 14 and 24 are a whole different debit card transaction at the pump at $3 gallon . As previously posted - hand calculate the miles driven ( dont forget to account for off tire sizes ) divided by the gallons put in till full again and you will get a pretty close #. Driving 300 miles on a 3/4 tank then stopping and putting 10 gallons in to just get you around a little more does not equate to 30 mpg

I'm running a php 6pos ts chip

Interesting. All three of my chips (1 tuner, 2 chips) all make my overhead wrong by 2-3 mpg.

OK today with my Bullydog GT tuner I put 25 gallons (100litres) and got 360 miles (600kms) with 1200lbs in the back. Is this good or bad?
