Latest
Major architectural overhaul: all 548+ definitions embedded in executable, pre-flash safety validation, vehicle-aware UI, Boost Auto-Tune, and expanded vehicle support.
New Features
- Boost Auto-Tune: automated boost control optimization with stability analysis and per-RPM tuning
- Vehicle Context System: features automatically filtered by vehicle type (turbo/NA, MT/AT)
- Pre-flash safety validator: blocks wrong-ROM/wrong-ECU flash attempts
- Processor-aware patch system: SH2, RH850, and HC16 instruction encoding
- Kernel integrity validation: SHA-256 hash verification for all 24 flash kernels
- Checksum validation added to pre-flight checks
Improvements
- All 548+ XML definitions embedded in executable - no external files needed
- O(1) Cal ID lookup via VehicleDefinitionRegistry (was O(N) LINQ scan)
- Inheritance resolution at startup - parent tables merged into child definitions
- Patch conflict detection: blocks incompatible patch combinations
- Removed ~1,850 lines of skeleton definitions with fabricated addresses
Vehicle Support
- Levorg (2014-2020): 19 definitions, SH72543 Hitachi
- Crosstrek/XV (2012-2014): 6 definitions, SH7058
- 2022+ WRX VB (FA24DIT): In development - coming soon
- 2015-2021 STI: 9 new definitions from SubaruDefs Alpha branch
- 13,780 tables propagated across 278 Cal IDs via automated scripts
Safety
- ROM size validation prevents flashing wrong-size ROMs to ECUs
- Processor family cross-check blocks wrong-architecture patches
- Blank/zeroed ROM detection prevents bricking ECUs
- Price corrected: $200/vehicle (was incorrectly showing $499 in Consumer Mode)
