Standalone ECU / Engine Management
The KMS Ultimate is the flagship of Kronenburg Management Systems' ECU range, aimed at the highest-horsepower and most demanding motorsport engines. It offers full sequential injection and ignition on high cylinder counts, staged or multiple injection, precise closed-loop lambda, advanced electronic boost and knock strategies, VVT control, and comprehensive motorsport functions and CAN, all configured in KMS Management Studio. The Ultimate targets extreme drag, time-attack and racing applications where lower-tier ECUs run short of channels or resolution. Tuners work in real time and log at high sample rates. Like the rest of the KMS line, it is a wire-in standalone that replaces the factory ECU and is unrelated to OEM reflashing.
The Ultimate is a flagship standalone for full race builds; Softechpro reflashes factory OEM ECUs with automated emissions/DTC modules, Stage tuning and checksum correction. They occupy separate lanes and complement each other in a mixed workshop.
