GIAC's Flashloader Handheld Switcher allows users to switch between GIAC-tuned software programs with the touch of a button. The product is a pocket-sized,hand-held device that plugs directly into the OBD port. It uses serial flashing technology and requires no additional hardware within the DME.
Switching is performed by selecting the desired mode with the touch buttons. Cycling the ignition will save the new mode to the ECU's memory and retain its state until switched again.
