This ethanol issue caused me to think. Our cars came with wiring for a coding plug (that PP sells) to modify the fuel map and it is used when lower octane fuel is used. Where does this plug physically go and would it help the ethanol issue? Would it help with smog tests?

Would someone with the plug and an AFR meter be willing to run a test with and without the plug installed?
