K24 SC 553WHP 1st run
This is the Autronic SM4 datalog from the first tuning sweep under load. Injectors are too small and maxed out causing a high speed lean out condition. Mapping has only just begun, and the Air/Fuel ratio's are a fair way out. This compromises power, economy and emission performance.
The SM4 has auto tune capabilities enabling quick and accurate mapping to be completed on the dyno.
