At 19.2 MPG, I used 38.54 gallons - a difference of about a gallon or 2.6% more fuel. If I'd done the 740 mile trip without regen at 19.7 MPG I would have used 37.56 gallons. At the end of regen the DIC showed 19.2 MPG. The truck entered regen at 700 and regen-ed for 40 miles. My trip this weekend averaged 19.7 MPG mixed over 700 miles. How much extra fuel does regen take? My best guess comes from the mileage adjustment I see under steady state operation.The weird thing is that the counter jumps quickly between 1-10 grams (maybe one gram per mile), counts slower from 10-19 grams (10 miles/gram), and then seems to count from 20-up much slower (20-30 miles/gram) Mixed driving might be closer to 20 miles, and of course on the dyno things move a little faster. On the highway, it may be 1 gram every 25-30 miles. How quickly does soot accumulate? It depends on usage.Of course it'll take longer if the cycle is interrupted. So if the DPF is at 44 grams, and regens down to 5, it generally takes about 40 miles. How long does it take to regen? Our test trucks average about 1 mile per gram of soot.The regen seems to last until the soot load goes below ~10 grams or so and the driving conditions no long promote regen. Whichever of these events occur first will start a regen. The truck will initiate regen once it reaches 44 grams of soot in the trap or travels ~700 miles since the end of the last regen. How often does the truck go into regen? Our experience has been that there are 2 common triggers for regen.
FASS 150 DURAMAX 2015.5 UPGRADE
FASS 150 DURAMAX 2015.5 SERIES
The SPADE series (Standalone Programming And Diagnostic Equipment) delivers the highest quality tunes on the market available in a simple to use OBD style flash tool. So, why not add tuning that maximizes the performance of your truck for everything you do with it? The SPADE delivers just that! What do you use your truck for? If you're like most, probably a little bit of everything, from hauling, work, daily driving, and some fun on the weekends. The same motor used on the HD Series (class 8 applications) is also used on our Titanium Series, proving once again that quality is #1 at FASS. This size difference allows you to tuck the pump closer to the frame for better clearance and less visibility without sacrificing any of the features known to FASS systems. Built into a smaller compact version, the Titanium Series offers flow rates up to 260gph. This pump is mandatory on our higher horsepower applications where fuel starvation can cause lack of power, poor shifting, and excessive smoke from low fuel rail pressure.ĭesigned for light duty trucks while utilizing all the best features of the HD series. Includes a filter and water seperator for additional fuel system protection. This pump ensures there's always a strong supply of clean diesel fuel to your high pressure fuel system.

Keep your CP4 Happy with Clean, High Pressure Fuel!įrom the factory the Durmax trucks are not equipped with a pump to push diesel fuel from the tank to the engine.
