Any Fit owners try this chip? Modest performance gain, improved mileage.

 

seems fake to me, I wouldn't go for it.

 

i wouldnt use it. if you get anny gains it will only be for a day until the ecu learns and re adjust

 

It's no logic circuit; the "chip" in these bogus products is simply a resistor, a five cent part, wired in series to one of your car's sensors, usually a temperature sensor, to try to fool the ignition/fuel system into running richer.
