MAZDA TRIBUTE G-Force Peformance Chip
Clearly just a resister in the IAT sensor wiring. My favorite part:
"The GForce Performance Chip reprograms your air/fuel ratio, ignition timing, and other aspects of your vehicle's engine to SAFELY increase the power, while increasing fuel economy significantly. Our chips are designed and programmed per vehicle. Your car will run smoother, run cooler and more efficiently at the same time. The gains we advertise are real, and are guaranteed with a money back promise. Our chips will not only increase horsepower, but torque as well for more REAL power. It increases power throughout the full RPM range unlike many competitors."
Oh...but it gets better:
"The GForce module installs into your MAZDA TRIBUTE's engine bay and is connected via 2 wires that plug into the IAT sensor. Diagrams are included. The unit is then able to reprogram the ECU thus improving your car's performance."
It reprograms your ECU through your IAT sensor. Wow...I bet a Mazda engineer (or even a NASA engineer) couldn't even do that. LOL!
