AFTERMARKET PRODUCTS AND YOUR VEHICLE’S WARRANTY  
Many of our customers ask, “Will your product void my vehicle manufacturer’s  
warranty?” While the answer is straightforward from a legal standpoint, we also  
want to educate our customers (and after-market consumers) on some industry  
realities and offer some common sense precautions to minimize your risk.  
Consumers of aftermarket products are protected by The Federal Magnusson-Moss  
Warranty Act. The Act states that if something breaks on your car and you take it  
in for warranty repair, the dealer must honor your warranty unless they can prove  
that whatever modifications you have added to your car actually caused the  
problem. Please keep in mind that towing in anything higher than level two is not  
recommended.  
While as a consumer, you have strong legal protection with regards to your  
vehicle’s warranty, there is also a practical reality that different automotive  
manufacturers and dealers have greatly varying views on aftermarket products, in  
particular those that produce horsepower, such as performance enhancement chips,  
modified intake manifolds, or aftermarket exhaust systems. There are dealers and  
manufacturers out there that will use the presence of a horsepower upgrade to void  
your vehicle’s warranty. They will do this regardless of whose product you are  
using. Any aftermarket company that does not acknowledge this is misleading  
you.  
The bottom line is that while the law protects the consumer and provides for  
enforcement of the warranty, it is very difficult for most people to hire an attorney  
and fight a voided warranty. Edge recommends that you always disconnect and  
remove your EZ module when you take your vehicle to a dealer for warranty  
work in order to not interfere with Diagnostic equipment.

About the Power Edge  
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.  
Warning: Do not stack the Edge LB7 EZ with the Edge  
LB7 Juice. It can cause severe damage to the engine.

Installing the EZ Module  
1. The Power Edge LB7 EZ Module can mount on top of or to the side of the  
black plastic fuse box cover located on the driver’s side fender. Adhere the  
module using the supplied Velcro, allowing enough harness movement for  
removal of the cover.  
Connecting The Harness  
2. Disconnect both stock  
Connectors  
connectors by squeezing the  
ears on the backside of the  
connector and pulling the  
gray lever.  
3. Gently insert the EZ  
connectors and lock in place  
with the gray levers, and then  
gently connect the stock  
connectors to the other end of  
the EZ connectors.  
Notice: Use caution when inserting connector bodies. If the connector does not  
slide smoothly, remove the connector, inspect the pins, and retry installation.  
Final Inspection  
4. Recheck all connections for a properly secure installation. Using the  
supplied wire ties, secure the wiring harness to prevent possible damage.  
5. Start the engine. The engine should start and run like a stock truck. If the  
engine does not start or run properly, turn off the motor, remove the keys  
from the ignition, then remove the EZ module and inspect the pins inside  
both connectors. Straighten pins or clear foreign material from the pins  
and connector surfaces, then re-install the connectors. If failure  
conditions still exist, contact your dealer or Edge Products, LLC. When  
trying to restart, make sure that the key has been turned off for at least 10  
seconds before cranking the engine  
.

Using The Power Edge  
LB7 EZ  
Adjusting Power Levels  
The EZ has three power levels. The EZ module was designed to allow the user  
to select any of the three power levels on the fly with the supplied three position  
switch. Level 3 is with the switch towards the tab.  
Power Level Confirmation  
To confirm the power level that you have selected with your switch, you can do  
the following procedure:  
1. Place gear selector in Park with your foot off of the accelerator while  
engine is idling  
2. Set the Parking Brake  
3. Place gear selector to reverse, neutral, reverse, then back to park. P-R-N-  
R-P  
4. The engine will rev to coincide with the power level selected, revving 3  
times for level 3 and so on  
Towing  
It is recommended that you use the Tow/Haul transmission mode while towing.  
This provides torque converter lockup in gears 2-5, which reduces transmission  
heat and also raises the shift rpm threshold to keep the rpm’s higher. It is  
recommended that you maintain engine rpm above 1800 while towing.  
While towing, the EZ module allows the engine to pull many grades in the mid  
rpm’s rather than having to downshift and pull them in the high rpm’s. This  
provides for lower EGT (Exhaust Gas Temperature) with the same power  
output. EGT rises significantly with rpm--especially above 2500. It is highly  
recommended that you install an EGT gauge while using the Power Edge EZ.  
It is recommended while towing you use power levels 1 or  
2 due to EGT and transmission stress

Power Gains  
The following power gains are representative of an actual test vehicle. These  
gains were measured on a SuperFlow Dyno at an altitude of 4400 ft above sea  
level, and represent power delivered to the rear wheels of the test truck. The  
only modification made to the test truck was the addition of the Power Edge EZ  
module. Power gains may vary somewhat on a different vehicle or in different  
geographic settings.

Making Sense of it All  
This section is designed to help you understand how the additional power will  
change your driving experience as well as help you figure out what power level  
will best suit your driving style.  
The first thing you will probably notice, especially if this is your first time  
driving a diesel truck with a performance module, is that this is a whole  
different animal. You will experience more power, quicker take-offs, better  
passing and acceleration and possible better fuel economy. Power level one is  
specifically designed to maximize fuel economy improvements (if you can put off  
the little guy on your shoulder telling you to step on it hard’)  
.
If you are towing, the beauty of the extra power the Edge EZ module delivers is  
that not only will you be able to maintain speed going up a hill, but the added  
power will also keep you in a higher gear, so your transmission will not keep  
“hunting” for lower gears. We recommend level 1 or level 2 for towing  
applications. Only use level two if you are towing a light load. Level 3 should  
never be used while towing. Level 3 is a great overall driving level. When  
driven responsibly, and used with an EGT gauge, level 3 will not stress the  
stock engine or transmission as long as you are not towing  
.
EGTs: What they mean and why  
EGT stands for exhaust gas temperature, and is the single most important  
indicator of how a diesel engine is performing. Unlike a gasoline motor, a  
diesel motor will continue to make power as more fuel is added. As more fuel  
is added, heat will be generated until the motor just gets too hot and things start  
to melt. This is a situation you want to avoid. Exhaust gas temperature is the  
ideal measurement of how hot the motor is, since temperature fluctuations in  
exhaust gas are almost instantaneous. Just so you know, it is possible to  
generate excessive EGT on a stock truck, particularly if you are towing. This is  
why we always recommend installing an EGT gauge.  
In our experience 1350 degrees is about as high as you want to let your EGTs  
go. Keep in mind, the stress on your engine created by the heat is a function of  
both temperature and time. A brief spike to 1400 that lasts a second is not that  
big a deal. Pulling up a hill for several minutes at 1400 is far worse.  
As you drive your truck in the various power settings, keep your eye on the  
EGTs. Depending on how you drive and where you drive, you may find a  
particular power level is more suitable to your power needs.

The EZ Module and your Transmission  
The automatic transmission has a fluid-filled clutch-like device called a torque  
converter. This device uses the spinning motion of the motor to drive the  
transmission which drives your wheels. As the truck speed stabilizes, the  
torque converter engages a mechanical connection which locks the two halves  
of the torque converter, so the output shaft is going the same speed as the input  
shaft. This mechanical linking of the two halves is called Transmission Lock-  
up. If the motor produces too much power, this mechanical lock-up can start to  
slip. When this slippage occurs, the EZ module reduces the power output to  
allow the transmission to function properly. This is a great feature that provides  
an extra level of protection for your vehicle.

Transmission  
The Allison transmission is a “Smart” transmission. That means that it pays  
attention to how smoothly the transmission is changing gears, and modifies the  
shifting to improve drivability. When the motor delivers more power (by  
adding the EZ module), the transmission has to ‘re-learn’ how to shift. After  
first installing the EZ module, you may notice rough shifting. The best way to  
re-teach the transmission is to set the truck in the power level you will be using  
most of the time. Then set out to drive, some city, some highway, varying the  
driving and the speed. Make sure that you shift through each gear 20 to 30  
times. A good rule of thumb would be 100 to 200 miles. Remember that the  
truck must go through each gear 20 to 30 times. You will notice the shifting  
becoming better, and your truck responding better to the additional power as  
you go through the learning cycle.  
Edge On Your Side  
Edge Products LLC takes a great deal of pride in the quality of our customer  
service. If you have any questions or concerns about your EZ module, please
