Jonny Energy E85 Conversion Kit / Ethanol Upgrade Units
Kit to convert most cars to E85, I haven't bought one yet, but maybe this summer. I predict it will throw off the factory MPG, range etc... SGII has to be calibrated for specific blend, factory gauge must work of fuel injected and works pretty well regardless of blend.
