workflows:
ecm_development:
description: Complete ECM software development for internal combustion engine
steps:
- Define engine specifications (displacement, compression, turbo)
- Design fuel injection strategy (port/direct injection)
- Implement ignition timing maps (MBT, knock detection)

- Integrate turbo boost control (wastegate, anti-surge)
- Implement VVT control (cam phasing optimization)
- Develop emissions control (EGR, catalyst light-off)
- Implement OBD-II diagnostics (readiness monitors)
- Calibrate on dyno (VE table, spark map, fuel map)
- Validate emissions (FTP-75, HWFET cycles)
- Certify for ISO 26262 ASIL-D (if applicable)
tcm_development:
description: Develop TCM software for automatic transmission
steps:
- Define transmission type (AT/DCT/CVT)
- Design shift strategy (upshift/downshift maps)
- Implement shift execution (torque phase, inertia phase)
- Develop torque converter lockup control
- Implement adaptive shift learning (clutch wear compensation)
- Develop manual mode (paddle shifters)
- Integrate launch control (DCT high-RPM slip)
- Implement fail-safe modes (limp-home 3rd gear)
- Calibrate shift quality (jerk <10 m/s³)
- Validate on vehicle (shift timing, smoothness)
emissions_certification:
description: Certify powertrain for emissions compliance
steps:
- Run FTP-75 drive cycle (cold start emissions)
- Run HWFET cycle (highway fuel economy)
- Validate OBD-II readiness monitors (catalyst, EVAP, EGR)
- Measure tailpipe emissions (HC, CO, NOx, PM)
- Verify on-board diagnostics (MIL illumination logic)
- Test durability (150k miles aging)
- Submit certification to EPA/CARB
- Monitor in-use performance ratio (IUPR)
calibration_workflow:
description: Dyno calibration for optimal performance and emissions
steps:
- Baseline VE table (volumetric efficiency vs RPM/MAP)
- Optimize spark timing (MBT vs knock limit)
- Tune fuel injection (pulse width, wall-wetting comp)

guidelines:
- Safety first: All control algorithms must have failsafe modes
- Emissions compliance: EPA Tier 3/CARB LEV III mandatory
- Calibration accuracy: VE table ±3%, spark timing ±1°, lambda ±2%
- OBD-II: All readiness monitors must complete within EPA drive cycle
- Diagnostics: Two-trip fault detection for MIL illumination
