Page 7: 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 for more than three minutes with the AFR sensor in the exhaust and the control module’s power disconnected or the “KEY”... -
Page 8: Installing The G100
Installing the G100 The G100 is graphically illustrated below. Installation should proceed in the following order: gauge and record/playback control pod (Option “R”), control module and power cable, AFR sensor and cable, and analog output (Option “A”). Do not modify any of the cables. -
Page 9: Control Module And Power Cable
G100’s control module and other electronics in your vehicle. The wire labeled “KEY” in the power cable is used to turn the G100 on and off. Connect the “KEY” wire to a wire from the ignition switch that is at 12V when the ignition key is in the “Run” position and 0V (or open circuit) when the vehicle’s ignition key if in the “Off”... -

(black) of the analog output should be within 0.020 V of battery ground when the G100 is on. Use a voltmeter to make sure this is true when the G100 is on. Also measure the voltage between what the ground wire (black) is about to be connected to (i.e. - Page 11 After the G100 has been calibrated, turn the ignition key off and wait until the sensor has cooled before installing it back into the exhaust. Your G100 is then ready to be used.

“foot-off-the-gas” deceleration. During fuel shutoff, the G100 will be pinned at 16 AFR (the AFR of air is infinity!). Press the throttle during a fuel shutoff and you will see the AFR come below 16 indicating that the engine is firing again. -
Page 13: Analog Output (Option "A")
During a recording, the voltage output is active and during playback, the analog output will match the replayed AFR. When there is a fault with the G100 and a trouble code is being “flicked” on the gauge, the analog output will be held at 0 V. -
Page 14: Trouble Codes 0
Trouble Codes Trouble codes are indicated by the G100 by “flicking” the needle over the “ECM” logo in the lower area of the gauge. There are five trouble codes (numbered 1 through 5) and they are indicated by the number of “flicks”... -

Page 16: Troubleshooting
If the G100’s needle is “flicking” a trouble code, refer to the “Trouble Code” section for more information. If you think that the G100 is displaying the wrong AFR value then one of five conditions exists: 1. The G100 needs to be calibrated. See the “Calibration” section in “Installing the G100”. - Page 17 Do not attach the battery until the installation is completed. Never work on a running engine. When installing the G100, 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), and caustic objects.
