What is everyone getting on their fuel range I'm getting around 360. I keep seeing some people getting 420 and 465. Any ideas? Reset ECU or is that about right?

 

Hi BeanWagon!

I have a pic in my gallery of 465.
I drove to Monterey for a conference and didn't stop to refuel until I hit Ventura (took Highway 1 to 101 to 405). So, when I did stop to fill, that is what it showed--in other words, it is an anomaly since I was driving a long distance at about 70-75.

When I first got the car, it was in the 298-300 range and was not pleased. 9 months later I seem to show in the 350-395 range at fill up--but I rarely go under half a tank between fills.

It fluctuates alot depending on my driving--stop and go or long hauls to g2g's at 4.30 am on a Sunday!

Hope that helps!

Mine used to always show about 390 to 410 at fill up, which is almost always after 35 mixed + 35 miles of fwy. Since I got the Hahn/BSR/PPC tune, it shows 420 to 440. Anyone know how far it "back calculates" the mileage when it gives your range?

 

On the way to work this morning I happend to check mine after filling up and it was the highest that I have ever seen 504, couldn't believe it so I ran it through the cycle again and it was still there!

 

Your Fuel Range will change and is calcuated from the level of Octane of the fuel added during fill up. Ie: the higher the octane, the higher range from the onboard computer.

Our last trip from Houston to Eufaula, Okla. Filled up with 87 Octane. Computer read 430 miles. Was able to go 417 miles before filling up.

When filling up with 98 Octane computer shows 480/520 Fuel Range.

The fuel you are using may have a high mix of additives. (Corn or Flex Fuel). or something to slow down and stabilize evaporation. That will result in a lower MPG rating.

The first time I used 98 Octane, I filled up with a 1/2 tank of 87 Octane and the range jumped from 420 up to 460 with out driving, just started the enging and recalcuated the (DIC).

Hope this helps.

 

I used the previous MPG from the computer and gives the estimate from that. It has no idea what octane you are pumping in at the pump.

Highest mine has displayed was 545 that I saw, filled up today after a road trip to GA and it read 518 today. All 87 with a E10 mix.

 

filled up yesterday and it read 514. time before was 504.

 

298 if I am LUCKY, most of the time I get about 250 per tank. All city, all short trips. It blows in town.

 

Filled up at Costco this morning: 345 on the DIC. OK I guess!
I was *just* under half a tank and only use their regular unleaded ($4.53!)

 

If you do normal driving (combination city/highway), then 360 is about right. Most higher numbers have been from long stretches of highway driving.

BTW, my top number was 603 last month.
