Fine tuning tests for powertrains
Fine-tune the settings and validate the overall behaviour of your engines
The Emitech Group carries out fine tuning tests (FTT) for thermal, hybrid and electric powertrains (TPG). The aim of these tests is to optimise the dynamic, energetic and thermal behaviour of powertrains by fine-tuning the parameters of calibration, electronic management and interaction between powertrain components.

Aims of the fine tuning tests
The development tests enable us to :
- Optimise engine control strategies: injection, ignition, torque, hybridisation, etc.
- Adjust control laws to meet consumption, performance or comfort objectives.
- Validate compatibility between components (engine, gearbox, inverter, battery).
- Reduce pollutant emissions and improve thermal management.
- Prepare for homologation or industrialisation.
What types of powertrain are involved?
- Thermal (ICE-D/G, MHEV, e-fuels, H2, NH3): engine calibration, injection/ignition mapping, thermal management.
- Hybrids (HEV, PHEV): thermal/electric coordination, mode transition management.
- Electrics (BEV, FCEV): servo optimisation, recovery strategy, torque response.
Test methodology
1. Preparation and instrumentation
- Integration of the powertrain on a motorised test bench.
- Instrumentation of key quantities: temperature, torque, power, pressure, voltage, current.
- Interface with calibration tools (ETAS INCA, CANape, etc.).
2. Mapping and calibration
- Recording of engine operating curves (fine tuning torque, fuel consumption, efficiency).
- Tests under different conditions: temperature, simulated altitude, variable load.
- Adjustment of engine or hybrid management tables.
- Validation of operating stability and reproducibility.
3. Dynamic validation
- Transient tests (acceleration, deceleration, speed changes).
- Analysis of powertrain behaviour under realistic or severe conditions.
- Verification of post-start behaviour, temperature management, back-up strategy.
