box.
The hand-held ECM programmer comes with a twelve month limited warranty from the

Vortech Engineering is not responsible for engine or ECM damage due to an improperly

the ability to re-program the vehicle’s ECM. It is necessary to disconnect the aftermarket
stereo from the wiring harness before continuing with the programming procedure.
