IMPORTANT INFORMATION ABOUT YOUR VEHICLE’S WARRANTY —

PLEASE READ!

Many of our customers ask, “Will your product void my vehicle’s

manufacturer’s warranty?” While the answer is straightforward from a legal

standpoint, it’s important to educate our customers (and all 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 vehicle and you take it in for warranty repair, the dealer must honor

your warranty unless whatever modifications you have added to your

vehicle actually caused the problem in question.

Edge is committed to providing quality products that are safe to use. Our

products do not cause damage to a vehicle when used as intended. Please

keep in mind that towing in anything higher than level two and hard driving

in levels four and five are not recommended. However, the reality is that

many dealerships have been known to void warranties on vehicles that use

aftermarket products as a matter of policy. This applies in particular to

those aftermarket products that produce horsepower, such as performance

enhancement “chips,” modified intake manifolds, or aftermarket exhaust

systems, regardless of product brand. Any aftermarket company that does

not acknowledge this is misleading you.

Although you have strong legal protection as a consumer in regard to your

vehicle’s warranty, the practical reality is that taking legal action against a

dealer or manufacturer to fight a voided warranty is a costly and time-

intensive process. For this reason, Edge strongly recommends you always

disconnect and remove your module/programmer and monitor when

you take your vehicle to a dealer for warranty work. It is also for this

reason that Edge focuses the bulk of their product development efforts on

producing modules and digital monitors that can be easily removed. Even if

you remove your unit, you should note that dealers can detect the use of

ANY programmer — Evolution or otherwise — even if the unit has been

removed.

This warranty is void for any new products purchased through auction websites.

Warranty is valid only for new products purchased through Authorized Dealers

(proof of purchase required for all warranty claims).

Edge Products, LLC

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.

About the Edge LB7 EZ

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.

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 Super Flow 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 is improved performance, especially if

this is your first time driving a diesel truck with a performance module, You

will experience more power, better throttle response, better passing and

acceleration and possible better fuel economy. Power level one is specifically

designed to maximize fuel economy improvements.

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.

GM LB7 EZ Manual

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 Relearning

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.
