4ĥ Recall Mode While in Default mode, pressing the Recall button (on the right of the knock retard display) changes the Scanmaster to Recall mode. The stored readings can be recalled anytime before the engine is turned off. The 6th decimal point (to the right of the knock retard digits) will be lit during recording. It will keep in its memory the highest knock retard reading and lowest O2 reading along with the MPH that they occurred. O2 0 = show stock O2 s on main screen, 1 = show wideband O2 on main screen Record Mode While in Default mode, if the TPS (Throttle Position Sensor) voltage exceeds roughly 3 volts, the Scanmaster will monitor O2 and knock retard.
1 = PLX or AEM Gauge, 2 = LC1, 3 = AEM Inline & AEM Ad2 not currently configured 4. Ad1 choose type of wideband (if one is connected to the Scanmaster analog input). To leave Configuration mode, hold the Mode button for 5 seconds. Press Mode again twice to save the parameter. Use the Recall button to change parameter. Press the Mode button to scroll through menu of items. To enter Configuration Mode, with the Scanmaster powered up, hold the Mode button for 10 seconds. Use this only if you have a wideband connected directly to the Scanmaster (not wired to the ECM). Optional analog input display wideband type (AEM, LC-1, etc). Boost & MAP display stock 2-bar MAP sensor or 3-bar MAP sensor 3. Default O2 display stock O2 reading or wideband reading 2. Configuration Mode The following display parameters are configurable: 1. You can also press Recall to return to O2 and knock. Each time you press Mode, it will scroll through data until you get back to O2 and knock retard again. Pressing the Mode button (to the left of the display digits) selects other data from various engine sensors. On the right side it will display degrees of knock retard, which correlates with how bad the car is knocking (detonating). On the left side of the display you will see O2 millivolt readings from the engine s oxygen sensor. Default Mode After the Scanmaster has synchronized with the ECM, it will enter Default mode. Once it has synchronized with the ECM, the display will change to (O2 millivolts and knock retard). If no data is received the Scanmaster will turn itself back off. 3Ĥ Operating Instructions Power Up On initial key-on, the Scanmaster version number will be displayed.

Connect the white wire to the serial data signal at the ALDL connector under the dash.
#SCANMASTER LT1 INSTALL#
You can install a male spade connector, which will push into an IGN terminal. One of the empty IGN terminals in the fuse box works well. Connect the red wire to a fused ignition power source. You can use a skinny male spade terminal to plug into pin A, which is ground. Mount the Scanmaster inside the car on the dashboard, or any other convenient location. Disconnect the battery negative cable under the hood. You can go there to find out about any recent updates.
