LeoVince’s new FAST II single-unit fuel and ignition system works in conjunction with the stock ECU. It will work with any exhaust system, but all of the pre-loaded maps were developed using U.S. fuels on U.S.-specific models with LeoVince systems. The basic kit comes with a control box pre-loaded with three exhaust-specific maps, a model-specific wiring harness, all necessary installation hardware, FAST II software and a CD with instructions. Suggested retail starts at $499.00. For more information, contact LeoVince USA, Dept. RW, 1445B S. 50th St., Richmond, CA 94804, (510) 232-4040, www.leovinceusa.com .
