Thank you for purchasing the Power Edge LB7 EZ Module for the Chevy/GMC 
Duramax® Diesel LB7.  The EZ module has been developed and produced 
from the highest quality materials available to ensure the best performance for 
years to come.  If you have any questions, please contact Edge Products.  We 
will be very happy to answer your questions about our complete product line (1-
888-360-3343). 
The EZ Module is an add-on Engine Control Module (ECM) for the Duramax® 
Engine that offers additional features not available with the factory setup. Since 
it is an add-on ECM, it uses all the factory data, and then enhances the factory 
settings to optimize your truck’s performance.   
These features include
•  Engine temperature monitoring and power increase from the EZ module 
as engine reaches operating temperature 
•  Three selectable power level settings that can be changed on the fly  
•  Smart power control during torque converter lockup to allow a smooth, 
easy torque converter clutch lock-up 
 
The EZ module offers a large power increase over stock throughout the rpm 
range, but the power is most noticeable in the midrange rpm’s.  This greatly 
improves drivability and towing performance.  Transmission downshifting is 
greatly reduced, especially while passing or towing.  
 
 
The EZ also regulates power delivery based on engine temperature.  This means 
that while the engine temperature is below 140
° F no additional fueling is 
delivered.  At 140
° F the module begins delivering fuel at 25% of the calculated 
additional fuel, and the percentage increases as the engine temperature 
increases, until at full engine temperature (174
° F) the EZ delivers 100% of the 
calculated additional fuel. 
All Edge modules and programmers are built to operate with OEM calibrations.  When 
you take your vehicle to a service center they may, by your request or otherwise, update 
your vehicles calibrations.  Therefore it is important that you return your vehicle to 
stock before taking it in for service.  Edge updates its active products (i.e. those 
currently being manufactured) to work effectively with updated OEM calibrations.  
However, this process can take some time as Edge is not always made aware of 
calibration changes made by the OEM.  In the case of discontinued products, Edge 
cannot ensure that your unit will work effectively if you take your vehicle to a 
dealership and you are given, by your request or otherwise, a new calibration.
