Finally you can switch power levels in an LML with EFILive Tuning by DuramaxTuner.com


The most commonly asked question about LML (2011 - 2016 Duramax) tuning is "When will switch on the fly power levels be available?"  Switch on the fly tuning has been available for the 2001 - 2010 Duramax trucks for years.  It offers many conveniences and is a favorite feature among enthusiast.  

Finally, DuramaxTuner.com has a working switch to adjust power levels while driving!  Much like the DSP5 switches for the previous model Duramax trucks, this new Switch on the fly LML Tuning offers a simple to install rotary switch along with the LML SPADE.

Pre-Tuned DSP5 ECM

What happened to Pre-Tuned ECMs?

When EFILive first came out there was no AutoCal.  Flashing had to be done in person with a V2 or in the very early years a V1 cable.  This left remote tuners a set of challenges.  How do you provide custom tuning remotely?  Of course, the answer was Pre-Tuned DSP5 ECMs.  The lynch pin of making the Pre-Tuned ECM program work was a steady supply of good core ECMs.  This meant the only downtime truck owners had was the time it takes to swap ECMs.  

There are a few critical downsides to Pre-Tuned ECMs though.  The first being a long term availability for good cores.  As years pass and more trucks are tuned and older ECMs are crashed and lost, cores disappear.  The OEM's do not provide an affordable replacement option and after a while, the cost of cores out weigh the benefits of Pre-Tuned DSP5 ECMs.  Another drawback is the ability, or lack there of, to verify the quality of each core module.  Many will take a flash with the bench harness and still show problems when installed.  

  • Easy to install
  • Minimal downtime
  • Relies on Core ECM program
  • Unable to test reliability of Cores

SPADE stands for Standalone Programming And Diagnostic Equipment.  It is also known as an AutoCal.  The hardware is manufactured and provided by EFILive and custom DuramaxTuner.com or Calibrated Power tunes are loaded onto them.  The SPADE is a very easy to use hand held tool that allows you to flash custom built EFILive tunes and data log, and read/clear most codes.

What is the the best tool a diesel enthusiast could ever ask for; a Mustang 4WD Chassis Dynamometer.  Why is that?  An 4WD Chassis Dyno gives you the ability to see exactly what your truck is capable of.  It also provides tuners the safe and controlled enviroment required to test calibrations and dial in your truck to best running condition.  Which in turn, gives you a truck that not only makes big power, drives as smooth as possible and gives you insight to when and how your truck performs at it's best.  

  • Find your PEAK Horse Power and Torque
  • Get the smoothest running truck possible
  • Gain insight into how and when your truck performs it's best

Many people have estimated horse power and torque numbers based on what someone else has told them.  A Chassis Dyno gives you the ability to know exactly how much power you have at the wheels.  No guessing or estimating involved since a dyno is a measurement tool at it's core.  

Beyond peak power, there is drive-ability to consider when you have a heavily modified truck.  Any tuner can make the peak power number, the difference between them is how the truck drives on the street.  Smoke output, shift points, throttle response and so much else can be dialed in when you are strapped to a dyno for testing.    

Diesel truck owners often want more RPM.  The logic here is that RPM equals power.  However, a chasis dyno gives you a clear picture of where and when your truck makes peak power.  When it comes to competing with your truck, this is crucial!  Diesel guys know all too well how close sled pulling or drag racing can be, so every possible edge really matters.

  • The LLY Duramax  is a great truck from the factory for there are 3 modifications every owner should make! The LLY was manufactured 2004.5 and 2005. There are a few 2006 models that are labeled as an LLY, however they have all of the LBZ upgrades from the factory, so for performance applications consider those an LBZ. An LLY was the first Duramax with the injectors outside of the heads, a variable vane turbo and a 50 state EGR.
