Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓No-start after fitting a used or salvage-yard Denso ECM
- ✓Failed engine ECU needing a like-for-like donor swap
- ✓Immobilizer mismatch / key-not-recognized after an ECU swap
- ✓Donor ECU with the wrong VIN or immobilizer data
- ✓Keeping your original keys while replacing a dead Denso ECM
Won't fix:
- ✗Emissions or readiness-monitor defeat - we do not delete cats, EGR, or O2 monitors
- ✗Internal hardware faults on a physically failed donor ECU
- ✗Engine mechanical, sensor, or wiring problems unrelated to the ECU
- ✗Tuning, horsepower, or performance remaps
