apr gas mileage

[Tunerstop]

did anyone notice better gas mileage? Cuz shiat, i got apr 91, and my gas mileage is 10000x better

[Alkemix]

LoL. Love the reaction. Do you have any actual figures to post? Like from empty to full fill up gallons and miles driven to empty?

[Tunerstop]

I dono but, with half a tank i would usually go 2 days. Now im going like 4 days with teh same gas and same route/driving style each day. Its great!

[Sharkfin]

how much is the mpg on the car computer changing?

[rayiish]

another reason why we should go apr!

[Glassnpowder98]

I got Revo'd and have definitely noticed an increase in gas mileage. However, with that extra HP it is definitely tempting to "drive like an ass" sometimes so I'm probably not getting the full benefit of the increase MPG's. But things will likely change as I had an epiphany last night when $40 didn't even buy me 3/4 of a tank of gas. $3.98 per gallon, thanks a lot OPEC!

[scoobycarolan]

My local APR dealer told me to expect my milage to shoot up. basically pays for itself after a while he said!

[minameismud]

+1 actual figures!

it'd help the WAF (Wife Acceptance Factor).

[konijay]

You get a better gas mileage because you don't have to step on it as much to get the power...
I usually fill up 16-16.5 gallons and it lasts 480 miles everytime... I don't think there is 250 horsepower car that gets this good MPG... i love it!!

[Ski DraGoN]

I get many many many more miles per gallon after APR as long as I drive normal.

[jahciple]

so which one actually gives you better mileage, apr or revo?

[HTMike]

newb question :

What is an APR ?

Im looking at either a low mile 2006 and a low mile 2007 2.0T Quattro with the manual trans.

A chip in general gives you better gas mileage

APR is a brand for a chip. Chips makes our cars go faster. as simple as i can put it

[SounderMN]

I think you guys are exaggerating, unless you drive extended highway distances regularly. Even if you are driving mostly highway, your gas mileage isn't going to double just because of chip tuning. You could see 5% or 15% improvement, but no way 100% improvement.

During my daily commute, 15 miles mix of highway and stoplights, I typically averaged (on the trip computer) 24.5 to 24.9 pre APR. Now, with APR 91, I typically average 25.9 to 26.3, given similar driving style. On longer highway trips, I'm seeing 2 to 3 more mpg than before. I have yet to try the APR93 program, since it's hard to find 93 gas in my area. Of course, when I put the lead plate in the bottom of my shoe, mileage drops quickly, accordingly.

Mileage has improved, but not enough to justify $700. OTOH, the smilitis it brings on makes up for the rest of the savings. haha

[4RingRook]

Another reason for a chip; I gotta get on this!

[VZWalex]

Funny you mention the Gas mileage .. I'm apr stage 2 with the FSI FP and I noticed my Gas mpg has not suffered .. in fact gotten a lil better with my normal driving ... and freeway mileage was awsome !! but be warned ... prepare to see gas go bye bye if your stepping on it.... Cheers!

[kooltechie]

I highly doubt chipping would give a substantial increase in gas mileage...at least I have not seen it on my own car.
in my own experience with the chip mod, the fuel economy seems about the same or "slightly" better.
being able to add more power without sacrificing the fuel economy was one of the main reasons I chose to chip my car

[ruckus]

before APR = 440 - 450 miles a tank, after APR 93 = 460 - 470 miles per tank. + the fun factor is a win win... why audi doesnt program these cars at these levels is beyond me.

I am assuming about 90% highway driving?

Your car is automatic, manuals generally are more fuel economic.

On another note, on my trip computer I've seen 30, 31, 32 mpg cruising on APR93

[jahciple]

this is what i got for the best mpg, 5 miles on the street and 20 miles on the highway with no chip.

[gpxluke]

I mostly drive in the city, I DO NOTICE A BETTER MILEAGE AFTER THE CHIP...it's amazing...I heard the chip can help the engine burn gas more effectively so we get better mileage

[fD3S]

this is what i got for the best mpg, 5 miles on the street and 20 miles on the highway with no chip.

Did you have a/c on? Maybe you were driving with the wind or something or going from a high elevation to lower? Anyway 35 mpg is great

[Auditude2.0T]

I have APR 93. APR FSI FP, FSI FP Program, AWE Exhaust, EC Testpipe, Forge DV, and Carbonio CAI and i get better gas mileage than stock. About 32mpg on the highway and 25-26 around town.

[ruckus]

ya, that's how we roll down here in S.FL

[Widget]

I was really bored in class tonight. I average 26.5mpg. On a 1mpg increase with gas @ 3.70/gal I would be looking at saving $0.005 per mile driven. That's about 100k miles pay off the $500 or so of software.

You buy the chip because you want the POWER not to save $$$.

[kooltechie]

the way I calculate fuel economy is based on the amount of gas I put in vs. the distance driven, and I check the mpg each time I go to the gas station.
in my case, before chipping, I got around 335 miles out of 14 gallons of gas and that's about 24 mpg.
after chipping, I still get around 335 miles out of 14 gallons of gas.
so the fuel economy before and after chipping is about the same for me.
however, considering my driving style IS slightly more aggressive than before, the fuel economy most likely is slightly better after chipping and this is great cuz my car has more power without sacrificing the fuel economy.

btw, I'm not sure if the mpg number displayed in DIS is as reliable as the calculations based on the amount of gas used and the distance driven.
no matter what DIS displays, what matters is the amount of gas you put in for the amount of distance you drive.

no ac, it was early in the morning like at 6:30am, it was from long beach to irvine.

[Mike@APR]

Our performance engine calibrations (aka software) run more advanced ignition timing than the factory calibration and this is where the bulk of the increased fuel mileage comes from. We can do this because, with our performance tunes, we require you to run a minimum of 91 octane or 93 octane depending on your region of the country. Audi has to plan that you will ignore the recommended 91 octane and therefore they have to reduce the timing advance to cope with the possibility that someone runs 87 or 89 octane. In addition, for emissions purposes, Audi wants to run as retarted a timing angle as possible (within reason of course...and they are still trying to be BTDC) in order to decrease the time that it takes to heat up the catalyst in the morning and keep it warm during idle for ideal emissions performance.

I could explain the scientific reasons for all of this but I can't give away all of my secrets. :-)

Honestly... I think this is the ONLY way calculate REAL gas mileage. your trip computer, although it is in the right direction, is no replacement for cold hard reality... what miles you drive and how many gallons you put in. I average every day on my work commute about 25-28 mpg each way on the trip computer and maintain those averages for all my weekend drives too, but when i calculate my REAL gas mileage, i get in fact 22-25 mpg, which isn't that far off, but if you calculate the 14 gallons i drove multiplied by 6 mpg variance, thats about 85 miles per tank variance. If you modded+chipped guys get the chance, try to post some figures based on this principle... remember to start counting miles immediately AFTER a full tank of gas and then see how many miles you drive till your next full fillup on the ODOMETER and not trip computer. I'm interested to see the results... if you guys can still get near 30 mpg... thats so awesome... it would rival my old 2005 civic with manual trans. (Yes... I used to drive one of those in college.)

[windextor]

I was averaging 29.6 mpg on my 160 mile per day drive before the chip and now average 33.2...I love it...

[Alkemix]

Did you say 160 miles per day?! Geezus man... you shouldn't even be driving a hybrid... you should just go straight to electric!

[SounderMN]

You're correct that the only true way to measure mileage is but dividing miles driven by gas consumed when you fill up at the pump. Obviously the computer deal is just an estimate. I haven't really checked too closely at the pump, but it seems close enough. The original question was about improvement in mileage from APR, so I think the computer estimate is probably close enough to judge how much it changes.

[marcus1701]

Am I the only one that lost 1mpg. I usually get 25mpg avg and now it's 23-24mpg for the last year.

[quattro.it]

Mine improved noticeably. I'd say I gained at least 3-4mpg and ~60 miles more per tank. The drivability is much better. Before I'd have to put the Tip in Sport for good throttle response, now drive works fine for normal commute bs. I only run Shell or Chevron and I've noticed this helps mileage over 2nd tier fuels even before APR. Audi can't tune to a higher hp level because thay have to account for the lowest common denominator in fuel quality or if dopes put regular in the tank as the gentlemen from APR mentioned.

[A4addict]

My gas mileage after my APR flash:



I don't even have my "E" light on yet, I could easily run 40 more on the streets and about 70 more freeway miles.

I've got a few questions in regards to this chip = gas increase thread.

I've owned two b7's
1.) 2005.5 80k mi 2.0tqm, color screen, problem with filling up the gas tank, REVO tuning.
2.) 2006 42k mi 2.0tqm, red screen, no problems filling up, APR tuning, 034 HFC

On my 2005.5 I bought it stock, and the only engine modification was the REVO tuning. I was getting around 450mi/tank when I upgraded to REVO, I was getting 550mi/tank with spirited driving, no problem.

Now I drive this 2006 that was stock when bought and I was getting around 400 mi on a good day, less than the old b7. So I bought APR thinking its basically the same thing as REVO but it has made my car worse I believe. Well except for the fact taht it is faster...or feels faster. If I am lucky and granny drive I can get up to 375-400, but usually with a few spirited driving sessions I get 325-350 max. But it also doesn't feel as fast as the old b7, and this car has more mods.

On my old b7 I had the color screen with the windshield wiper stalk nipple that lets you toggle the MPG/distance til empty and it was always high 20's or low 30's Highway it was like 35 but I never trusted it so I just always set a trip odometer to track the distance traveled on one tank of gas. On my new car I have the red screen and so it is just the distance til empty, but it seems like everytime I turn my car on the miles left decreases by like 20-30 mi.

At first I thought that maybe the fact my gas tank always had problems filling up could have been the difference, but then after some research I saw that was irrelevant, so I began to think it was the REVO tuning, I know there are three individual selectable numbers that allow you to control boost, timing, fuel...After checking out some more of these forums I have not seen any car that is getting over 500 mi/tank on average, soI guess it was just a good "problem" with my old b7, still I wish my b7 right now would do better than 350 mi/tank. Any suggestions on how to get this up? I am going to do the spark plugs, oil change, K&N drop in, and hopefully get a boost gauge installed over the weekend, and hopefully see some increase, although I don't think I can squeeze 100 mi from just the spark plugs. Any help would be appreciated.

Thanks! Happy Holidays.

Instead of miles per tank, take the extra 10 seconds and divide the mileage on the trip computer by the amount of gas you just put in. Accurate MPGs.

You do realise that the tank level sensors are not very accurate and therefore the DTE is not very accurate. Our cars have 17.4 gallon tanks. The reserve tank kicks in at 15.5 or so. So when you hit 0 you have roughly 2 gallons left. Thats a lot of leeway when you are doing back of the napkin MPG calculations. doing it the way I stated above is pretty much foolproof.

If you do a lot of city driving you'll get significant;y less MPGS as well. When I commuted on the highway I got pretty decent MPGS, even though it was a lot of stop and go traffic. Now my commute is 2 miles each way all city and my MPGs suck, because my car barely gets up to temp before I get to the office and I rarely get above 35mph. I don't expect any sympathy though, its not a bad "problem" that my commute is so short!

[968Reckless]

APR= good gas
