ABSTRACT
Test bench systems for engines register two major types of data: synthetic variables in the scalar form characterize the overall operation of the engine and vector quantities characterize the engine cycle. This data is stored and analyzed either during the test or in post-processing mode. Advances in the field of electronics and computing have allowed for modifying and facilitating these approaches, at the control level and also concerning measurement and test systems. Due to the complexity of existing electronic control units, the number of tests as well as of automation solutions and decision-support tools have increased sharply.

Conclusion
For several years now, the work of tuners and testers has been profoundly modified, mainly by the arrival in force of electronics and computing, both in engine control and in measurement and test equipment. In the past, the job consisted of fine-tuning by adjusting parameters and settings on the test bench, whereas today, with the arrival of ECUs, all operating possibilities must be considered, as well as the transition from...
