Mission: Design, develop and manufacture precision automotive instrumentation and control products for OEM and aftermarket segments. Approach: Most Split Second products are designed to work along with a stock ECU. These products make it possible to make a variety of performance enhancements while maintaining OEM levels of drivability. Split Second products interface to the stock ECU through various sensor inputs. This approach preserves and utilizes the OEM mapping while making real-time adjustment possible. Split Second products are widely used to add turbos and superchargers to naturally aspirated engines. Focus: Piggyback fuel and timing calibrators that maximize flexibility while minimizing cost.
