With your laptop, LS2-edit provides everything you need to tune your car. Our package includes the interface cable for your vehicle, the Cable Interface Module, the USB cable to your laptop, and the software to read, program, and edit your ECM and your TCM on your laptop. Mailing via air is even included (to U.S. locations, shipping outside the U.S. is extra).



LS2-edit runs on Windows 98 (Second Edition), Windows NT, Windows XP and Windows 2000 operating systems.  Minimum hardware requirements are a 400 MHz Pentium or AMD processor with at least 64MB RAM. You will also need one available USB port on the PC.  This is used for the vehicle interface module we provide.

One word of caution: if you want to add additional E/TCM's for LS2's at a later date, you will need to return the Cable Interface Module to us for updating.



The E/TCM-locked version of LS2-edit can license between 1 and 4 PCM's. After 4 licenses, you will need to purchase an additional LS2-edit package.

A word of warning: Please only program your E/TCM using an LS2 file that was read from your specific E/TCM. Do not try to program your E/TCM with an LS1 file from a different E/TCM. To minimize programming time, we do not completely reprogram the E/TCM, only the data segments. If you use a different LS2 file, the data in the LS2 file may not match the code already stored in the E/TCM. If you attempt this, you may end up with a E/TCM that is non-operational.
