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.
