AFTERMARKET PRODUCTS AND YOUR VEHICLE’S WARRANTY
Many of our customers ask, “Will your product void my vehicle’s 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 and
hard driving in level three 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 and intakes. 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 box or chip 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 module when you take your vehicle to a dealer for warranty
work in order not to interfere with Diagnostic equipment.

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).
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 Jeep CRD EZ
Introduction
Thank you for purchasing the Edge EZ Module for the Jeep CRD 2.8L Turbo Diesel.
The Edge 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.
• The Edge EZ Module is an add-on Engine Control Module (ECM) for the
Jeep CRD 2.8L Turbo Diesel Engine that offers additional features not
available on a stock engine. 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.
The EZ module offers a power increase over stock throughout the RPM range, but
the power is most noticeable in low to midrange RPM’s. This greatly improves
drivability and towing performance. Transmission downshifting is greatly
reduced, especially while passing or towing.

Module Installation
The Edge EZ Module can mount on the flat black plastic fuse box cover located in
the engine compartment, right in front of the battery on the driver’s side. Attach
the module to the top of the fuse box using the supplied VELCRO® strips,
allowing enough harness movement for removal of the cover.
Harness Connector – Your EZ module may be equipped with a harness that can
be disconnected at the EZ module itself (See figure 1A). It is important to make
sure that your EZ module is always connected to the harness when the wiring
harness is connected to the truck, otherwise the truck may not run properly, or may
trip engine “codes.”
FIGURE 1A
Important: The truck must be turned off and the keys pulled out of the
ignition for at least one minute prior to installation or removal of the
connectors and module.
1. Remove the plastic engine cover by taking off the yellow oil cap. Replace
the yellow oil cap once the cover is off.

rail on the driver’s side towards the rear
of the engine. Plug the supplied
pressure sensor connector into the stock
pressure sensor on the engine and the
stock engine wiring harness connector
into the supplied pressure sensor
connector.
4. Run the wire with the switch into
the cab of the truck so the switch is in
a convenient but safe place.
Final Inspection and Operation
5. Recheck all connections, fittings and fasteners for a properly secure installation.
6. Using the supplied wire ties, secure the wiring harness from possible damage
from moving engine parts.

Adjusting Power Levels
-Stock
-Level 1
- Level 2
The Edge EZ Module offers 2 levels
of power beyond stock. The power
from the Edge EZ Module begins by
plugging the module into your Jeep.
The power levels are adjusted by
changing the “in cab” switch position
to the level you need. Adjusting
power levels on an EZ module has
never been EZier!

How to Use Your Edge EZ Module
Using your Edge EZ Module
This section is to help you use the Edge EZ module effectively and add enjoyment
to your diesel truck experience.
The first thing you will probably notice especially if this is your first time driving a
diesel Jeep with a performance module is that you will experience more power,
quicker take-offs, better passing and acceleration, and even better fuel economy.
Level one is specifically designed to maximize fuel economy improvements.
Another thing you may notice is that your Jeep is suddenly a lot more responsive to
drive. Now, a word of caution; normally, driving the stock
Jeep you have a feel for how fast you are going in each gear, but that changes with
the EZ module. You may find yourself doing 55 in a
35 mph zone or taking corners too fast. Be cautious and be aware that there may
be an adjustment period to your new-found power.
Towing
What about towing? What can this do for you when you are towing? The great
thing about Edge EZ Module and all the other Edge® power modules is that they
were created for towing. That is why Edge built them, and why we keep making
them better. Let’s assume that in a stock Jeep you would pull your 2,000lb load up
the grades in 3rd gear. Your EGT (Exhaust Gas Temperature) may run at about
1200° F. With the EZ module on level 1, you have effectively increased the
horsepower by 10, and the torque by 15 Foot-pounds. That is like adding a fifth
horse to pull a four horse carriage. That is representative of how much your power
has increased. That means you will be running at a lower rpm and your EGT has
decreased. And best of all you are going faster and the truck may have already
shifted into 4th gear. Power level 1 is designed to match fueling with any
additional upgrades you may have done to your vehicle. Power level 2 should
never be used while towing. In hot weather when the vehicle is warmed up and
while driving in stop and go traffic level 2 should only be used for a few minutes.
Level 2 is designed to take advantage of the built-in safety margins the
manufacture needs to add in order to make sure your vehicle can tow at its
maximum capacity. When driven responsibly, and used with an EGT gauge, level
2 will not stress the stock engine or transmission as long as you are not towing or
driving in hot weather with stop and go traffic for more than a few minutes.

Exhaust Gas Temperature
Now let’s talk about the different power levels and the Exhaust Gas Temperature
(EGT) readings, and what they mean. As mentioned earlier the EGT tells you how
hot the exhaust gases are in the exhaust manifold coming from the engine. This is
important because you shouldn’t let them run for long periods above 1350 F. The
higher the level, the more fuel is fed to the engine, and potentially, the higher the
EGTs. Since towing is harder on the engine and the transmission, we recommend
that you tow in level 1 for a load. This will protect you from putting too much
stress on the engine and transmission. Level 1 is a good all-around mode, allowing
for better economy and better performance, while not stressing the engine and
transmission. We recommend that you run your truck in level 1 or lower for your
normal daily activities.
