driveability improvement with the stock camshaft; however, the real benefits of your Crane Powermax Performance Power Tuner are realized with the improved engine breathing provided by a Crane "Truck-Power" camshaft. Your Crane Power Tuner contains all of the proper "tuning data" necessary for your vehicle's on board computer to properly manage your engine/transmission system with just a camshaft change or with the addition of other "bolt-on" performance components such as: low-restriction intake and exhaust systems; superchargers, different gear ratios; different tire sizes; etc. In other words, your Crane Powermax Performance Power Tuner allows you to improve and personalize your vehicle with a wide array of performance "goodies" and still maintain good driveability, economy and reliability! This has been achieved through extensive dynamometer development and "on-the-road" testing. We have tested our performance data against the data of established "custom tuners" with their proprietary programs and laptop computers, and we have not yet had to take "second place"! This assures you that with a Crane Powermax Performance Power Tuner you are getting the peak performance from your engine combination. In your hands is absolutely the most powerful "hand-held" tuner in the industry! We are also proud to say that it has been developed and manufactured here in the USA!

BUTTON means YES when choosing a menu item. BUTTON means NO when choosing a menu item.

What You Can Do With The PowerMax Power Tuner:

· Change your vehicle speed limiter to match the speed rating of your tires (Note; take care to assure that the speed rating of your tires matches the highest intended operating speed of your vehicle). · Allows you to adjust the level of tuning to the grade of fuel: Low, middle, or high octane; with automatic fault adjustment in case low-grade fuel is accidentally used with high-octane tuning mode · Adjust your speedometer/odometer to compensate for oversize/undersize tires within ¼" OD (25" to 44" on most trucks). · Adjust your speedometer/odometer/engine management system for changes in gear ratios (2.73 to 5.13 for most applications) · Provide 3 custom levels of tuning for your stock engine/transmission system (in addition to the stock fac-

CAUTION: Unless these directions are followed step-by-step, the vehicle and/or the computer may be rendered inoperable! Step 1: Fuse Removal

The first step in the programming process requires the removal of certain fuses. Some fuses govern special equipment options and will interfere with the programming process. (This does not mean that you cannot use these options with the Crane Power Tuner; it simply means that these options must be disabled during the programming process, only!). All fuses must be re-inserted after the programming process is complete. The location of the fuses, for the GM applications, are shown below.

Figure 1.

LET'S BEGIN: Before operating your Crane Cams Powermax Performance Power Tuner:

· Read this entire instruction booklet carefully. The stepby-step instructions will make using your Powermax Power Tuner much easier. The Powermax Power Tuner will perform many steps automatically. · Be sure the vehicle's battery is fully charged before using the Powermax Power Tuner. Do not attempt to reprogram your computer with a low charged battery or while connected to a battery charger. · Turn off all electrical systems: Lights, radio, air conditioning, fan, CD/DVD players, power-amplifiers, cellular phones, etc. · Set the parking brake. This turns the Daytime Running Lights (DRL) off. If left on, this may interfere with programming. · Disable the OnStar feature if equipped. · Disable all necessary equipment by removing the appro-

The interior fuse panel is located inside the door on the end of the dashboard as shown above in the picture on the left. The underhood (exterior) fuse panel is located under the hood adjacent the driver's side fender as shown in the above picture on the right. As stated previously, you will have to disable the Special Equipment Option of the vehicle. To do so we have included the schematic diagrams of the fuse boxes below.

Whether your vehicle is equipped with these options or not, you must pull these fuses.

Using The Crane PowerMax Power Tuner With Crane Truck-Power Cams

The true benefit of the Powermax Performance Power Tuner is the ability to allow the use of various Crane Cams "Truck-Power" camshafts in your vehicle. These camshaft part #s are listed below along with their relative "Cam Performance Level" (ex: Cam Perf 1; Cam Perf 2; or Cam Perf 3). These "performance levels" are the tuning parameters necessary to make the vehicle drive properly with the selected camshaft. Simply select the camshaft part # you have purchased for your vehicle and use the related "Cam Perf #" for your camshaft. Cams that are listed as "Cam Perf 1" are cams that have high idle vacuum and are designed to enhance low-end and mid-range performance. They are ideal for heavy duty towing and general driving. Cams that are listed as "Cam Perf 2" are designed for

mid-range power and torque improvements with little to no loss in stock low-end power. They can be used for light to medium towing as long as the tire size and rear axle ratio are appropriate. Cams that are listed as "Cam Perf 3" are designed as "Sport-Truck" cams. This usage does not anticipate heavy towing. These cams are designed to maximize mid range and top end power with only a slight, but acceptable loss of low-end torque. NOTE: Cams that are listed as "Cam Perf 2" and "Cam Perf 3" have been designed to be used naturally aspirated or with superchargers providing a maximum boost of 6 PSI.. Check fuel injector flow rate to assure adequate fuel supply with a supercharger. Your Crane Cams Powermax Performance Power Tuner is capable off controlling higher flow fuel injectors!
