OBD Fuel/Gas Saver ECU Chip

How it Works:
The FS3 uses an exclusive process of Dynamic Soft-Flashing not available anywhere else. Each FS3 comes programmed with a set of EPROM addresses that directly affect fuel efficiency. When the ECU attempts to read one of these addresses, the FS3 patches the factory value with one from its on-board highly tuned map.

所有跟帖： 

• 誰會去用1個unknow的EPROM去flash自己的車？找s。除非給出原碼(詭計也就不存在了) -味苦- ♂ (0 bytes) () 02/08/2013 postreply 21:21:27
