Message	A narrow band to tell if it's rich or lean, an oxygen sensor for lean (excess oxygen) and a fuel sensor for rich. (excess fuel) It could be used to account for the mixture changes caused by E85, but that's not the best way to go about it. Better/more efficient to tell the ECU what it's getting instead of making it react and compensate. -Dan "Capitalization is the difference between helping your Uncle Jack off a horse, and helping your uncle jack off a horse."
