LRX Updater v2.969


This is for the LRX device Updater software. The download link for the ZIP file is at the bottom of this page. Please scroll down to download and Unzip it to your computer before proceeding.


After unzipping the file, you will double click Setup.exe to install. You can search your computer for LRX Updater to save a shortcut on your desktop or taskbar, or navigate to your Program Files > Lund Racing and you'll see the LRX Updater folder there and you can create a shortcut from that. 


Once installed and program is open, you can plug your LRX device in and it will Auto Connect. If it fails to, then unplug the device, close and reopen the software and repeat the process. 


Once it's connected it will automatically sync to the cloud to upload or download files. To force it to upload/download just click Update. 


April 2024 UPDATE: If you have v2.968 softer or older, the updater will auto-sync the log to the cloud and you have to let us know after you sync. On v2.969 and newer you will download the log(s) yourself. After you datalog for us, you plug in the device to your PC and open the Updater app. You can now download your logs and send them to us in your ticket vs cloud syncing them! To do this, you would need the latest 2.969 or newer software. You would go to "Log Files > Engineering Logs > Save" and follow the prompts to save the file locally to your PC before uploading to your Ticket. This will NOT cloud sync so make sure you save them to a location you don't forget or the logs will be lost. 


When we upload tune files you will repeat the update process and see those tune files in the Vehicle Files list. You would then plug the device into your OBDII port in the vehicle and follow the onscreen prompts to flash it via the "Programming" menu.
