Honda Bosch MED17.9.3 ECU Clone & Programming
The Bosch MED17.9.3 is a gasoline (petrol) engine control unit used on Honda applications. When one of these ECUs fails, a bare replacement won’t run the car until its data is matched to your vehicle — normally a dealer coding and immobilizer-synchronization job. Our clone service handles it: we read the data off your original MED17.9.3 and write it onto a matching donor, so the ECU you get back is a genuine plug-and-play match for your car.
What we copy across
Working from your original ECU, we transfer the complete flash and calibration, your VIN, and your immobilizer (immo) data onto the replacement MED17.9.3. Every value lines up with what your car already expects, so the cloned ECU installs ready to run — no dealer flash, no immobilizer pairing, and no key re-coding after fitment.
Applications
The MED17.9.3 is a Bosch MED direct-injection turbo-petrol engine control unit. It is fitted to the Civic, Jazz, HR-V, CR-V and Accord petrol models (and Acura equivalents).
Exact fitment depends on the engine, transmission, market and model year, so please send us your part and software numbers before ordering and we’ll confirm your unit is an exact match.
How ordering works
- Place your order here and complete checkout.
- Ship us both units — your original MED17.9.3 and the matching replacement — using the packing instructions we email you (or drop them off at our Calgary shop).
- We read your original, clone the data onto the replacement, and bench-test it (usually same-day, within 24 hours of arrival).
- We return the finished ECU ready to install.
Turnaround & shipping
Most orders are cloned, tested and back out the door within 24 hours of reaching our bench. We’re based in Calgary and welcome local drop-off from Calgary and the surrounding communities, with Canada-wide and international shipping for everyone else.
Warranty
Our cloning work carries a 12-month warranty. If a unit we cloned develops a fault in that time, we’ll re-clone or repair it; in the rare case it can’t be put right, we’ll refund the service. The warranty applies to the original purchaser and covers our workmanship on the clone.
Before you order
We need to be able to read your original ECU to copy its data, and your replacement must be the correct matching MED17.9.3 hardware. If your original is completely dead, or you’re unsure the two units are compatible, message us with your part and software numbers first and we’ll tell you exactly what to send.
