Review on Innovative Performance Power Programmer Mazda Replacement Parts best for Engines & Engine Parts by Chad Cypert

No electrical thing can change the smooth shifting of an RX-8 automatic transmission. All of this is controlled hydraulically in the transmission valve body. Also, you cannot change the fuel map of an OBD2 equipped vehicle when a module is connected to the wiring harness. This product may not function as advertised and is nothing more than a resistor. in an anodized metal box. On the other hand, this is a very nice anodized project box that you could use elsewhere.
