Kt200 Ecu List May 2026

The primary reason tuners buy the KT200 is its coverage of the Bosch EDC17 and MED17 families. These ECUs are notoriously difficult to read via standard OBD due to "Tprot" (Tuning Protection).

The KT200 list covers these ECUs via Bench mode efficiently:

| ECU Model | Protocol | Notes | |-----------|----------|-------| | Denso 89661 | CAN | Many models | | Denso 89663 | CAN | Bench for full backup | | Denso 275800 | K-Line | Older engines | | Mitsubishi E6T | K-Line | Some Asian markets | | Bosch ME17 (Toyota) | CAN | Limited support | kt200 ecu list

| ECU Model | Protocol | Notes | |-----------|----------|-------| | Bosch ME7.3.1 | K-Line | Ferrari 360/430 | | Bosch ME9.7 | CAN | Maserati QP | | Marelli IAW 5SF | K-Line | Fiat/Alfa | | Marelli IAW 7GF | CAN | Diesel support |

When comparing the KT200 to tools like the Kess V2 or Ktag, the list of supported protocols is surprisingly similar. In fact, many users utilize KT200 hardware with "cracked" versions of Kess software, effectively mimicking the Kess V2 protocol list. The primary reason tuners buy the KT200 is

The Pros of the List:

The Cons:

Bosch represents the largest segment of the KT200 list.

EDC16 / EDC15: Legacy diesel ECUs are fully supported via OBD and Bench.

ME/Motronic: Support for older petrol injection systems (ME7, ME9) is robust, including support for various checksum types.
