Starting LS1M

To start LS1M, click the “home” button until you see the LS1M icon. Tap the LS1M icon to bring up the LS1M Main Menu. From this main menu, tap any of the buttons to bring up the screen you want to use:

•Scan: The basic scanning screen. Use this to view and log engine parameters.

•Saved Logs: Use this screen to recall data that was logged in the Scan screen.

•Auto-Log: Set up the scanner to automatically log data based on any set of conditions, such as SPD > 30 or TPS >= 90.

•Collect LTrims: This screen will work on cars equipped with LS1 & L67/L36 engines and certain other GM vehicles. It extracts the long-term fuel trims that the computer uses to adjust the air/fuel ratio. Used mainly for computer tuning for modified vehicles.

•Accel Test: This screen is used to measure a vehicle’s acceleration by timing it from a standing start to 60 mph, or other user-selected speeds.

•Trouble Codes: Use this screen to view the trouble codes reported by the vehicle’s computer & reset the Service Engine Soon light.

•Gauge: Displays just a few parameters in a large font. Useful for in-car monitoring.

•Misfires: This screen will count up the reported misfires on each cylinder to help isolate an engine misfire.

•About LS1M: Version info and available memory.

•Config: Set options on the behavior of the scanner.

Engine type and other configurable items:

LS1M supports enhanced parameters on two types of engines: the LS1 V8 and the L67/L36 V6. Click on the Config button to bring up the Config screen.
