2014 Evolution DD15

Does your dash have boost pressure, current mpg weighted over 8 seconds, avg. mpg, or any gauge your ECM can display? You should open your mind a little. FASS does what it claims, provem over and over again.

 

Yup. Prolly the only gauge I lack, from the factory, is a vacuum gauge to tell me when the air filter needs replaced.
I can even set desired mpg goal and instrument cluster shows - & + arrows to show when I'm achieving that goal at any given moment.
I used reset fuel economy avg after each trip. But last summer I began tracking a longer avg.(oil change to oil change). Of course it shows me current avg while going down the road.
I guess the only difference, is that it calculates the avg after every complete gallon consumed.

 

What engine / trans / rearend? What;s your mpg?

 

DD15 562hp 1850tq/big 13spd/3.42s

Summer 6.3/winter 5.9. Typically I set the cruise around 67mph.
I don't run CA because of my reefer unit and I stay out of the NE. The rest is pretty much fair game. I do see quite a bit of NE, KS, CO, WY

 

Would you like a $6000 raise? What tires?

 

I have 18 Michelin SmartWay tires. Truck was factory spec'd with them.

 

OK, not sure if you want a raise or not, lol, but if you slowed down to 62, you'd most likely save 0.5, or $6k per year if fuel, I also fined it more relaxing, just better.

 

I hear what you're saying. I just think the whole thing is kinda ridiculous though.
My last truck had a 450 ISX, no smartway tires, and I drove it the same as I do this one. It easily got 6.5 everyday with the same or better pulling power.

 

But it didn't have all this performance and fuel robbing pollution crap on it did it. Some believe if you took all that crap off a DD15 you'd have an easy 9, maybe 10 mpg motor. So the manufacture's givith and our government takes it away. Course they (gov.) want both, overnight!

 

Don't know if this will help but key on-engine off,fan speed control all the way left,temp all the way right,defrost-heat-vent all the way left,hold A/C and recirculation buttons until lights blink and it should go into factory reset mode
