I thought a few of you would be interested in the mileage change after getting my Superchips Flashpaq. I took a drive to London today (about 100km away) to see what kind of fuel mileage I could get out of my truck.

First, I loaded the Mileage XS SAVE tune onto the truck for the 100km drive to the city. I didn't pay much attention to my mileage in the city because it was busy, lots of stop and go traffic and I don't do enough city driving to worry about mileage there, I'm usually about 95% highway. On the way home I used the Performance tune for the first 50km and then put the truck back to stock for the last 50km. I drove very easy on the gas accelerating and set the cruise to 90km/h.

Mileage XS tune - 10.9L/100km (21.58 US MPG/25.92 Imp. MPG)
Performance tune - 11.0L/100km (21.38 US MPG/25.68 Imp. MPG)
Stock/no tune - 11.5L/100km (20.45 US MPG/24.56 Imp. MPG)

As I see it, there is no reason to use the Mileage XS tune... you may as well have the power there if you need it to pass or for whatever other reason. As of right now, I don't know if I'm going to even keep the Flashpaq as the main reason I wanted it was to try and get a little better fuel mileage. 1 MPG gain will take a long time to pay for itself! I also wanted it to adjust for tire size, but I can deal with the slight difference as I have the correct speed set up on my Scan Gauge II. It's nice it has a Scan Tool in it but I already have that in my Scan Gauge II and a separate code reader. I'm going to play around with it more, but as of right now it doesn't seem like it's worth the cash. I may change my mind once I see what the difference is on my 20km drive to work. I usually average about 12.7L/100km. If I can get it down to a steady 11.5 or something around there it may be worth it. Hope this info helps anyone considering the Flashpaq or Mileage XS. It definitely works, but you need to do a lot of driving to make it worthwhile if you're buying for mileage.

By the way, I'm using it on a 2007 Level II 4.0L auto trans w/ 33's which is rated at 11.9L/100km highway mileage stock.

 

what about the power output. and can u adjust anything on the trans?

 

that sucks...

 

It's supposed to add something like 19hp/16tq or something like that. I never drove it in a way to see if I could feel any results. I was more concerned to first see the mileage results.

 

I hear ya there... lol I'm still going to see how it works out on my shorter drives to work, whether it helps the mileage much there. If it does, it'll be worth it. If it doesn't then the price of it isn't worth it to me, for what I wanted a tuner for.

 

I think you can, I haven't checked into it yet.

 

Took it to work today... it doesn't help mileage on short trips. I got the same mileage going to work as I did without it. After lunch I put the tune back to stock and put 'er back in the box. I bought it from work so I'll be shipping it back later this week.

Don't get me wrong, it's not a bad unit. It works great, just not for what I wanted it for. Lots of people say they get much better city mileage with it than without, but I drive highway 95% of the time so just watching my speed and acceleration gets me the same results.

 

Doing mileage checks over short distances does not give you reliable information. Do it over several tanks of gasoline, at least 1 000 kms, then average the results.

 

My Scan Gauge is on every time I drive my truck showing average & instantaneous mileage. I take the same roads at the same time each day and fill up at the same gas station every week... most of the time at the same pump. lol
My trips to and from work are nearly always within 0.2L/100km of each other so I think I'm safe to say it didn't help!

 

Well, in that case, you have an excellent idea of the mpg you're getting.

Btw, what's a "level II" Ranger?

 

Level 2 is the off road option. you get skid plates, ranchos on the old model and bilstens on the new. it also comes with different interior trim. leather, buckets w/ console, twin sticks as opposed to a manual with a shift-on-the-fly dial. different rims. fx4s came with only alcoas and level 2's only came out for a couple years.

adam, your as OCD as me. i try and use only one gas station, unless i take long trips. i try and use petro canada stations only since i have points. fill ups are generally in the 65-70L/fill so i can keep track of my milage better. i've got 3-4 receipts in my console tha i have to log in the data from my trip to silver lake and chi town.

 

I more or less only use one station because the one I pass coming home from work sucks so it's the next closest one because all the others are out of my way. I don't really write any of it down. I just sort of remember what it's normally at. Last thing I want to see is how much of my money goes to fuel when I'm filling up nearly once a week!

 

i hear you. i'm used to filling up at 65-70 every two weeks . if it's more in a shorter time or whatever, i know something is wrong either with o2 sensors or cat or whatever.
