Page 5: Introduction
Dynojet™ stack system. AFR can be displayed and graphed by the Dynojet software along with RPM and horsepower. The DJET1000 kit comes with a tailpipe probe; however, the AFR sensor can be removed from the probe and mounted into a 18mm x 1.5mm boss in the engine’s exhaust. The DJET1000 adapter module can also accept AFR information from other ECM products such as: AFRecorder, Lambda Pro, and a G100 gauge. -
Page 6: Important Operation Notes
Important Operation Notes 1. Before installing the AFR sensor, apply a small amount of non-lead containing antiseize compound to its threads. Do not get the compound on the sensor’s tip. 2. Do not operate an engine with the tailpipe probe or AFR sensor in the exhaust for more than three minutes without the AFM1000 control module powering the sensor. -

2. Remove the Dynojet Air Fuel Ratio module if one is installed on the stack. You cannot use the Dynojet Air Fuel Ratio module and the DJET1000 Kit at the same time. 3. On the bottom of the DJET1000 adapter module is a label and access to a rotary switch. - Page 8 4. Plug the DJET1000 adapter module into the top of the stack. Make sure the pins in the connector engage properly and push it in straight. DJET1000 adapter module mating connectors 5. Plug the wiring harness into the AFM1000 control module.

Page 13: Using The Djet1000 Kit
Using the DJET1000 Kit 1. Start the engine in the vehicle to be tested and run it until no visible water vapor or liquid water is coming out of the exhaust. This is to minimize the chance of liquid water striking and thermally shocking the AFR sensor. - Page 14 This purges the trapped air. After the purge cycle is complete, make a second dyno run to collect accurate AFR data. If the trapped air is not purged, leaner than actual AFR readings will be read. 7 After the dyno run, re move the probe from the exhaust and close the tailpipe probe's On/Off valve and remove the probe from the exhaust.

Page 15: Application Notes
Application Notes 1. The biggest killer of AFR sensors is liquid water in the exhaust. Liquid water strikes the hot sensor and causes it to crack. Before any dyno run, make sure that the exhaust system is well heated and that liquid water cannot be seen coming out of the tailpipe. 2. -
Page 16: Troubleshooting
Troubleshooting If the AFM1000 has been calibrated, its red light off and green light on, the probe at least 18” up the exhaust pipe, the tailpipe probe's pressure at 20±3 psig and ejecting exhaust, and the exhaust system has been purged, the AFR measured will be accurate. If the AFM1000’s red light is on or flashing, refer to the AFM1000’s Instruction Manual. -
Page 17: Safety Warnings
Always wear eye protection when working near engines, vehicles, or machinery. When installing the DJET1000 kit, it is best to think-out your moves before you make them. Route and cable-tie all cables away from hot, moving, sharp, high energy (spark), caustic objects, and where people walk. -
