The Dynojet dynamometer is one of the best, maintenance free dynamometers on the market today. However you may have to service minor parts on the dyno to maintain optimal performance. Because some parts are considered ”WEAR ITEMS”, they may not be covered under warranty. This includes but is not limited to: air/fuel pump maintenance kits, air/fuel filters, O2 sensors, and tachometer pickup cables. All questions concerning replacement of air/fuel service kits or air/fuel filters can be found in your operations manual which is located in your Winpep7 software.

One product that Dynojet recommends you purchase is an www.apc.com> APC Battery back up power supply. We recommend this product due to the high call volume of customers that have had their equipment damaged by lightning strikes or power surges. Dynojet will not warranty any piece of hardware that has been damaged by lightning or power surges.

To have optimal connectivity with your Dynojet dynamometer and electronics, certain recommendations are provided below:

• USB to 9-pin adapters is NOT recommended. They don’t work.
• We always recommend using HP printers with all of our Dynojet products
• Note book computer docking stations are NOT recommended due to the fact that they can’t keep a solid connection with the Dyno electronics.
• To be compatible with the Dynojet electronics, a computer with a minimum of 500 MHz processor is required. In addition, Windows 2000 or XP is needed to run Winpep7 software.

Your Dynojet Dynamometer is equipped with an Eddy Current load absorption unit, a Digital Air Braking system or both. With your Eddy Current braking system you will be able to command a percentage of “load” to your vehicle to hold a desired RPM, simulate wind drag, and step tests. Also with this option, you can purchase the Torque cell upgrade witch can calculate the percentage of torque your vehicle is producing at a desired RPM.

With the Torque cell upgrade there will be minor calibrations needed to keep accurate torque cell numbers. We recommend you calibrate your torque cell after initial warm up of the dyno.

When using the Digital Air Brake option you may have to make minor adjustments to the brake pads to accommodate for pad wear. You can find out how to make this adjustment by consulting a Dynojet technician at (800)992-3525. Also you should make sure when using the Digital Air braking system you should have filtered air being fed to the dyno at approximately 60psi.

The Dynojet Dynamometer is equipped with two inductive pickups, a primary and a secondary. The primary pickup has a smaller clip on the end which will only accept a signal wire on the primary side of the coil. The other pickup is known as the secondary. It has a larger diameter clip on the end and should be used around a spark plug wire. The secondary wire should be used ONLY when the primary signal wire is not easily accessible.

For diesel applications, we offer an optional Optical Inductive Pickup. Retail price is approx. $300.00 and can be purchased through Dynojet by calling (800) 992-3525.
