Work History
Powertrain Calibration Engineer
Stellantis North America (FCA)
03.2023 - Current
- Calibrated and validated Grand Wagoneer 24 model Year in High Altitude (Colorado), Hot weather (Arizona) and cold weather (Minnesota) to ensure Transmission Shift quality, system failure function and testing metrics meet functional intent and implemented calibrations accordingly using ETAS INCA
- Prepared and provided technical reports of activities carried out following project's Quality Gates schedule
- Resolved ratio fault/EOL learning issue for 24 Grand Wagoneer program by calibrating the time between boost and stroke and worked with Idle team to reduce engine RPM to get to setpoint for EOL learning
- Worked and coordinated with supplier ZF for Transmisson hardware changes and verified proper transmission operation across operating conditions
- Involved in RAM 25 model year development calibrations and helped my team to review the calibration data using MDA data analysis tool
- Triaged fast feedback vehicle data and used general engineering tools DVP&R and lessons learned to keep track of current ZF 8HP transmission shift quality to improve future calibration software configurations
- Triaged and documented AVL test results using Matlab to ensure transmission Shift quality and confirmed features can be further optimized to increase AVL score
- Successfully executed on-road testing programs, collecting real-world data to validate and refine calibration strategies for optimal performance in diverse driving conditions.
