Reprogramming ECM - Duramileage?
Has anyone tried this? I copied this from the powerupdiesel website
SO WHAT EXACTLY IS DURAMILEAGE?
DURAMILEAGE is the product that will do all the things you were hoping for... that the others promised to do... but could not.
First off... DURAMILEAGE is NOT:
* an off the shelf hand-held programmer
* a performance chip that installs in the factory computer
DURAMILEAGE is the "recalibrating" of your truck's ECM with proprietary fuel maps that were developed by more than 25 years of GM automotive experience.
The ECM, also known as the ECU or PCM, is the "brain box" that controls and manages the injection of fuel into the motor. It does this by using sophisticated formulas and feedback from several engine sensors to regulate the air/fuel ratios.
Properly recalibrating or remapping these "fuel tables" results in changing the "peak efficiency" of the motor... which in turn increases its fuel efficiency.
In recent years manufacturers have set these tables to favor "better emissions" over fuel efficiency which has caused the fuel mileage of the diesel engines to drop.
When we remap the fuel tables on the ECM... your engine now has a faster torque rise at a lower RPM... resulting in a stronger "bottom end" power band.
This significantly improves the fuel economy because the engine does more work with less effort.
Diesels are a workhorse engine and are designed for LOW-RPM... HIGH-TORQUE output.
When the factory takes the power from the botton-end and moves it further up the RPM just to cut emissions... you also lose the power you need to get big loads moving out of the hole.
With the capability to "Fine-Tune" over 50+ potential fuel tables and engine functions... our primary tuning option for the Duramax diesel is our High-Mileage Fuel Economy Tunes... which also provide modest horsepower gains of 65HP for improved towing.
Also... we can perform High-Performance POWER Tunes and "HOT-Racing" Tunes (150HP+) that blow away any hand-held programmer's so-called "HOT" tune because we can fine tune more engine functions.
We individually customize each truck owner's ECM with an unlimited range of "tried and true"calibrations... resulting in wider variety of performance levels that far surpasses ANY aftermarket performance products currently available.
With years of knowledge and experience selling diesel performance upgrades... I truly believe that our DURAMILEAGE tuning is the most effective and safest way to increase your Duramax's fuel economy by as much as 4-7 miles per gallon.
It makes for interesting reading at least. What do you guys think? Has anyone tried this???
