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. WARNING! Programming your vehicle may expose existing defects in your vehicle’s PCM that could cause your vehicle to become disabled. It is strongly advised that you do not program your vehicle in remote locations in case of failure to properly program. If you have used another tuner/programmer on your truck, you will need to return your truck back to stock before using the Evolution. You will also need to remove any aftermarket chip you have placed on your truck before using the Evolution. NOTE: Failure to remove a plug-on chip before programming the PCM may result in permanent damage the PCM. 4 Evolution FORD Power Stroke 7.3 Liter About Your Vehicle’s Warranty 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 MagnussonMoss 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 they can prove that the failure was directly related to whatever modifications you have added to your vehicle. 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. Aftermarket products may also interfere with diagnostic equipment. If you should require service or warranty work, Edge Products always recommends that you disconnect and remove any aftermarket performance products from your vehicle when you take your vehicle to a dealer, in order not to interfere with diagnostic equipment. Please keep in mind that Edge Products does not recommend towing in any level higher than level two. These levels are for high performance only. 5 Evolution FORD Power Stroke 7.3 Liter About the Evolution Congratulations on purchasing the Evolution by Edge Products, the leader in diesel electronics and power gain technology. The following manual contains information and instructions on the proper use of the Evolution. Please read carefully before proceeding to program your vehicle. Note: Read the product disclaimer before programming your vehicle. Tow Program This setting is the lowest power setting. It is designed to provide a significant increase in horsepower and torque while still being safe enough to use for towing. While it isn’t necessary, a modified exhaust system will help improve overall performance and help reduce your EGT (exhaust gas temperature) levels. Race Program If you plan to tow with this program, it is strongly recommended that you make appropriate modifications to your exhaust system and install an EGT (exhaust gas temperature) gauge to aid in the prevention of potential damage to your engine. Note: This setting is legal in California only for racing vehicles which may never be used upon a highway. For more information, consult a qualified diesel mechanic. Extreme Program This program is not designed for towing. If you plan to tow, program your vehicle to the Tow program. It is strongly recommended that you make appropriate modifications to your exhaust system and install an EGT (exhaust gas temperature) gauge to aid in the prevention of damage to your engine. This setting is legal in California only for racing vehicles which may never be used upon a highway. For more information, consult a qualified diesel mechanic. 6 Evolution FORD Power Stroke 7.3 Liter Stock Program It is recommended that you return your vehicle’s computer to the stock program prior to returning your vehicle to a service center. This will eliminate the possibility of interfering with any diagnostic equipment. Diagnostics The Evolution also has a powerful, built-in diagnostics tool. Now you can view any diagnostic trouble codes (DTCs) that may be stored in your vehicle’s computer and make appropriate repairs. Once repairs are complete, you can also turn off that annoying “Check Engine” light. No more expensive trips to the dealer for a diagnostics scan. 7 Evolution FORD Power Stroke 7.3 Liter Display and Keypad The following screen is a sample Evolution screen. Great effort has gone into making the Evolution programmer very simple to use. The arrow keys are used to scroll through options on the screen, and the (enter) key is used to select desired options from a menu, or move to the next screen. The ESC (escape) key is used to return to the previous screen. Use the arrow keys to scroll through and select options on the screen. To select an option, scroll to the desired option with the arrow keys and press the button. In the example below, Power Programming is selected. 8 Use the key to accept a selected option, or to move to the next screen. Use the key to return to the previous screen. Evolution FORD Power Stroke 7.3 Liter Getting Started This manual is designed to help you understand the process of programming your vehicle as well as performing simple diagnostics on your vehicle using the built-in scan tool. There are also convenient troubleshooting tips included in this manual. If you experience problems using this product that are not covered in this manual, please contact our technical support line at (801) 476-3343. To handle your call quickly and efficiently, please have the product Part Number (ex. EEF1000), the current Version Number (ex. E1.24.15) and the Date of Manufacture ready prior to calling. This information is listed on the silver sticker attached to your Evolution programmer. IMPORTANT STEPS (Prior to Programming): • Make sure your battery is fully charged before programming your vehicle. • Do NOT unplug the Evolution while programming is in process. This could cause your vehicle to become disabled. • Some types of radio equipment, electrical accessories, and cellular communications devices can interfere with the programming process. Either turn off or remove all devices from the vehicle. • Close the doors on your vehicle and keep them closed during the programming process. • Set the parking brake on your vehicle to deactivate the daytime running lights. • Remove any other electronic power enhancing modules from your vehicle before programming. This includes aftermarket programmers and chips. IMPORTANT NOTE: ALWAYS Disconnect your Evolution while your truck is not in use. The Evolution does not turn itself off and uses the power from the truck’s battery. Failure to unplug the Evolution is equal to leaving your dome light on and could drain your battery. 9 Evolution FORD Power Stroke 7.3 Liter Connecting the Evolution 1. Turn the ignition switch to the OFF position. Locate the diagnostic connector under the dash near the steering column or under the glove compartment and connect the Evolution cable to this connector.

Depending on your selection, you will see one of the following displays: TOW 17 Evolution FORD Power Stroke 7.3 Liter RACE EXTREME 18 Evolution FORD Power Stroke 7.3 Liter STOCK (This selection only appears after the first use) 6. Press to continue or to return the Choose a Program menu. 7. After pressing to verify the calibration selection, the following screen appears: 19 Evolution FORD Power Stroke 7.3 Liter Please read and understand the following: SPEED LIMITER WARNING: Installing the RACE and EXTREME power levels removes the vehicle’s speed limiter. The speed limiter is designed to govern the vehicle’s speed based on the manufacturer’s TOWING CAPACITY WARNING The Evolution programmer is designed to increase your vehicle’s power output. It DOES NOT alter the engine, drive train, or suspension components that limit the maximum towing capacity. Towing trailers that exceed the manufacturer’s limitations and recommendations may cause damage to your vehicle’s engine, transmission and produce 8. After reading and accepting the disclaimer, the Evolution prepares to program the PCM. You will see the following display: 20 Evolution FORD Power Stroke 7.3 Liter 9. You are then instructed to turn the key OFF. Press when ready: 10. The following display instructs to turn the key ON. Do not start the engine: 21 Evolution FORD Power Stroke 7.3 Liter 11. The Evolution begins programming the PCM. During this process, you will see the following display: The programming process takes approximately 2 to 3 minutes to complete. 12. When the programming process is finished, the following screen appears: 22 Evolution FORD Power Stroke 7.3 Liter 13. After turning the key OFF, the following screen appears: 14. After pressing , the Evolution tests the PCM for communications. If successful, a truck does a “Burnout” and the FINISHED screen appears: Programming is now complete. You may now disconnect the Evolution from the Diagnostic Port: 23 Evolution FORD Power Stroke 7.3 Liter Update Required: It is possible that there may be a vehicle that is not currently in our database. (A result of a vehicle getting the latest file update from a dealer for example.) When this occurs, the message “Update Required” appears immediately after storing the Stock calibration. The following display shows an example: If this should occur, please contact Edge Products for a return authorization number (RMA number) and return the unit to Edge Products. We will extract your original calibration from the unit, then reprogram the unit and return it to you at no charge. 24 Evolution FORD Power Stroke 7.3 Liter Programming Interrupted: If at any time the programming should be interrupted for whatever reason, the Evolution should be able to completely recover the PCM. Simply reconnect the programming cable into the Diagnostic Port of the vehicle and restart the programming process. In order to simplify the recovery process, the Evolution will only program the original calibration and you will not be able to select any performance options. This is to ensure the complete, original calibration is returned to the PCM. Once recovery is complete, the Evolution function will return to normal. 25 Evolution FORD Power Stroke 7.3 Liter Diagnostics The diagnostics scanner built into your Evolution is a powerful tool that allows you to view and clear trouble codes on your vehicle. Trouble codes are the messages your vehicle’s computer logs to let you know there may be something wrong with your vehicle. The “Check Engine” light on your dash is activated by the presence of some trouble codes. If you selected Diagnostics from the initial option screen after plugging in the Evolution, the screen displays the following message: 26 Evolution FORD Power Stroke 7.3 Liter Retrieving Codes If you want to retrieve and view the trouble codes on your vehicle (trouble codes are what makes your “check engine” light come on) select the Retrieve option. Make sure your ignition is in the ON position, but the vehicle is not started. If you have trouble codes, they appear on the screen like the following example: If you have no trouble codes, the following screen appears: 27 Evolution FORD Power Stroke 7.3 Liter Clearing Codes If you want to clear the trouble codes on your vehicle (trouble codes are what makes your “check engine” light come on) select the Clear option. After selecting the Clear option, any current trouble codes are cleared from your vehicle’s PCM and the “check engine” light goes out. However, if you do not address the issue that caused the trouble code in the first place, the light will eventually come back on. The screen looks like the following: 28 Evolution FORD Power Stroke 7.3 Liter Data Stream Monitor The Evolution also monitors 5 PIDs (Parameter IDentification), often called ‘Data Streams’ from your truck. These values might be useful to monitor, particularly the transmission fluid temperature. NOTE: Always remember to disconnect the Evolution when you turn the vehicle off so you don’t drain the battery. 1. After selecting the Diagnostics option, the following screen appears: 2. Select the Data Stream option and press [Enter]. The following screen appears: 29 Evolution FORD Power Stroke 7.3 Liter Since these values are constantly changing, you have the option of freezing the screen to capture these values.

When the test is complete (the desired distance or speed is reached), the test will automatically stop and your result will be displayed on the screen. 33 Evolution FORD Power Stroke 7.3 Liter Quarter Mile Display The Evolution displays your 60 foot, 1/8 mile, and 1/4 mile times in addition to your MPH at 1/4 mile. The quarter mile run also has the option to save one run. You can recall this run at anytime. You can also save over it with a better run if desired. 0 to 60 Display The Evolution displays the time it took to go from 0 to 60 MPH. 5. After the test is complete, press to return to the Performance Menu. 34 Evolution FORD Power Stroke 7.3 Liter Power Gains The following power gains are representative of an actual test vehicle in factory stock configuration. Power gains may vary from vehicle to vehicle depending on model year, engine condition, fuel quality or geographic location. In addition, modifications to the engine, turbocharger and/or fuel delivery system may significantly affect power output. Programmer Setting Horsepower Gains Torque Gains Level 1 (Tow) 60 100 Level 2 (Race) 80 140 Level 3 (Extreme) 100 200 35 Evolution FORD Power Stroke 7.3 Liter Troubleshooting/Tips Tip: Programming your vehicle may expose existing defects in your vehicle’s PCM that could cause your vehicle to become disabled. It is strongly advised that you do not program your vehicle in remote locations in case of failure to properly program. Tip: Keep in mind that the Evolution is a high performance product and that not all vehicles deliver the exact same power output when programmed with the Evolution. It is recommended that you select a program that will best fit your needs. Whether towing, or traveling long distances at high speeds, choose your power level wisely and keep in mind the condition and tolerances of your vehicle when selecting a suitable power level. • NO RESPONSE / NO DISPLAY - If you do not get a response from the Evolution or the Evolution fails to power up when you plug it into the OBD-II diagnostics port, check all of your fuses and make sure your battery is fully charged. A blown fuse or low battery can prevent the Evolution from powering up or properly communicating with the vehicle. • THEFT LIGHT (on Excursions) - If the theft light flashes rapidly after programming and the vehicle won't start, the Passive Anti-theft system (PATS) will need to be reset. To reset the PATS, perform the following steps: 1. Turn the key on, but do not attempt to start the vehicle. 2. Wait for the theft light to quit flashing rapidly. This should take about 45 seconds, after which the THEFT light will flash multiple times about every 3 seconds. 3. Turn the key off and remove the key from the ignition for 30 seconds. 4. Insert the key and turn the ignition to the ON position. 5. The THEFT light should illuminate for about 5 seconds and then go out. 6. Continue to start the vehicle normally. 36 Evolution FORD Power Stroke 7.3 Liter Technical Support 888-360-3343 To expedite your support call, please have part number (i.e., EEF1000), version number, and Date of Manufacture ready prior to calling support. 37 Evolution FORD Power Stroke 7.3 Liter Commonly Used Acronyms ACT ACV AOD APP AXOD BCM BOO BP CCD CCO CDR CEL CFI CID CKP CMP CPS DTC ECA ECM ECT EDF EDIS EGO EGR EGRC EVP EVR FDM FPM HEGO IAT ICM IDM ISC = Air Charge Temp = Thermactor Air Control Sensor = Automatic Overdrive Transmission = Accelerator Petal Position (Diesel) = Automatic Overdrive Transmission = Body Control Module = Brake On/Off Switch = Barometric Pressure Sensor = Computer Controlled Dwell = Converter Clutch Override = Crankcase Depression Regulator = Check Engine Light = Central Fuel Injection = Cylinder Identification Sensor = Crank Position Sensor = Cam Position Sensor = Crankshaft Position Sensor = Diagnostic Trouble Codes = Electronic Control Assembly = Electronic Control Module = Engine Coolant Temp = Electric Drive Fan Relay = Electronic Distributor = Exhaust Gas Oxygen Sensor = Exhaust Gas Recirculation = EGR Control Solenoid = EGR Position Sensor = EGR Valve Regulator = Fuel Delivery Module = Fuel Pump Monitor = Heated Exhaust Gas Sensor = Intake Air Temp = Integrated Controller Module = Ignition Driver Module = Idle Speed Control ITS IVS KAM KOEO KOER KS LOS LUS MAF MAP MAT MCU MIL OHC OSS PCM PFE PIP PSPS SES SIL SPOUT STAR TAPS TCM TFI TGS THS TPS TTS VAF VAT VSS WAC WOT 38 = Idle Tracking Switch = Idle Validation Switch (Diesel) = Keep Alive Memory = Key On Engine Off = Key On Engine Running = Knock Sensor = Limited Operation Strategy = Lock-up Solenoid = Mass Airflow Sensor = Manifold Absolute Pressure = Manifold Air Temp = Microprocessor Control Unit = Malfunction Indicator Light = Over Head Camshaft = Output Shaft Speed Sensor = Powertrain Control Module = Pressure Feedback EGR Sensor = Profile Ignition Pickup = Power Steering Pressure Switch = Service Engine Soon = Shift Indicator Light = Spark Output Signal (from ECA) = Self Test Automatic Readout = Throttle Angle Position Sensor = Transmission Control Module = Thick Film Ignition System = Top Gear Switch = Transmission Temperature Switch = Throttle Position Sensor = Transmission Temperature Switch = Vane Air Flow Sensor = Vane Air Temperature = Vehicle Speed Sensor = WOT A/C Cut-off Switch = Wide Open Throttle 39
