The FlashZilla v3 is a handheld programmer that connects to your vehicles OBDII port and allows you to tune your ECM without removing it from the vehicle. The FlashZilla v3 allows you to upgrade, downgrade or reset your ECM to stock as you wish. Though this tuning method adds a bit of cost, it saves you the hassle and down time associated with removing and shipping out your ECM.
Here's how it works: First we ship you the FlashZilla v3 programmer, you plug it into your cars OBDII port, download your stock ECU ID file, we will then send you the new tuned file for you to upload to your car.
** The FlashZilla v3 program is Windows only however, there is a tutorial on how to run it on a Mac here**
