Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓No-start after installing a used/junkyard Honda or Acura ECU
- ✓Blinking immobilizer/key light after an ECU swap
- ✓Immobilizer system fault with a donor ECM that won't run
- ✓Replacing a failed PGM-FI ECU while keeping your keys
- ✓Donor ECU coded to a different car's keys
Won't fix:
- ✗Emissions or readiness-monitor defeat - no cat/EGR/O2 deletes
- ✗Performance tuning, K-Pro/Hondata jailbreaks, or remaps
- ✗Physically failed donor hardware (we clone data, not repair boards)
- ✗Mechanical, sensor, or wiring no-start causes unrelated to the ECU
