NISTUNE engine control units (ECUs) are used worldwide in all forms of competition. Specializing in Nissan/Infinity ECUs, NISTUNE programs have earned a reputation for meticulous and complete tuning. An ECU contains much more than just the parameters for a single maximum-horsepower point. Tuning only in this single dimension - without regard for other attributes like throttle response, thermal control, or torque - simply is not optimized tuning!

CZP Core Charge($300): An Additional $300 Core Charge applies to all CZP ECUs, and is charged at initial purchase of ECU. Once the Customer receives the CZP ECU, they must then return the ECU to receive their core amount($300). The additional core charge will not show up on the internet invoice.
