So I am looking for an EFIE to hook up to my O2 sensor, the problem is that I would like to be able to switch between my standard A/F to a Leaner A/F. I could buy a fancy piggyback with preset Fuel Curves but I don't feel like spending $800. I am also wondering what effects supplementing my fuel without A/F adjustment will be. I would like to use the HHO as a performance additive and then be able to switch to a more Economic A/F setting.
