Flashloader Mobile Device

The GIAC Flashloader Mobile (FLM) Device is a new tool that allows enthusiasts to load or remove GIAC performance programs on to their vehicle. The FLM is pocket-sized, durable and does not require a laptop or PC during the flash. Files and commands are stored on a USB memory stick, that can be customized by the end user, to convert the device from flashing tool, to logger, to performance mode switcher, to code clearer or to some combination of each.
