KT200II Supported Vehicles and ECU Protocol Search Guide

KT200II Supported Vehicles List 2026: How to Search ECU and TCU Protocols

The official KT200II Supported Vehicles Finder helps technicians verify compatible vehicles, engine control units, transmission control units, processors, memory information and programming modes before purchasing the tool or beginning an ECU or TCU operation.

A supported vehicle brand does not mean that every ECU, TCU and programming function used by that manufacturer is available. Professional compatibility checking should identify the exact control unit and required operation instead of relying only on the vehicle name.

What Is the KT200II Supported Vehicles Finder?

The KT200II Supported Vehicles Finder is the official searchable compatibility database for the KT200II ECU and TCU programmer. It allows workshops to research the available protocol before preparing cables, opening a controller, loading a file or placing an order.

At the time this guide was prepared, the official finder displayed the following database totals:

6,023Total Records

5,477ECU Records

546TCU Records

The database is updated as product coverage develops. Always use the live KT200II Support List rather than relying on an old screenshot or copied third-party list.

What Information Does the Database Show?

Database field	How it helps the technician
Category	Distinguishes ECU, TCU and other listed controller types.
Vehicle brand	Provides the manufacturer or application direction.
Vehicle type	Helps distinguish cars, trucks, motorcycles, agricultural equipment and other supported categories.
Model	Narrows a protocol to a vehicle model where that information is available.
Engine or transmission	Connects the controller record with the relevant powertrain application.
ECU or TCU manufacturer	Identifies Bosch, Continental, Delphi, Denso, Marelli and other controller manufacturers.
ECU or TCU type	Shows the controller family or exact variant.
Micro or MCU	Helps confirm the processor and distinguish similar controller versions.
EEPROM or memory	Provides useful memory information where listed.
Read and Write	Indicates the type of operation associated with the record.
Connection mode	Shows OBD, Bench, Boot, JTAG, BDM or another listed access method.

Why Compatibility Should Be Checked Before Purchase

The number of supported brands is less important than support for the exact controller and operation used in your workshop.

Before choosing KT200II, prepare a representative list of the ECUs and TCUs you service most frequently. Search each controller and check whether the available operation matches your work.

Questions to answer before ordering

Is the exact ECU or TCU family listed?
Does the processor match the physical controller?
Is the required Read function available?
Is the required Write function available?
Does the operation use OBD, Bench, Boot, JTAG or BDM?
Is a Virtual Read or physical Read provided?
Are Flash, EEPROM or Micro operations listed?
Does the job require cloning or only calibration programming?
Which KT200II version matches the vehicle coverage required?
Are additional adapters or connection accessories needed?

Do not purchase or program based only on a vehicle brand. One vehicle model can use different ECUs according to engine, production year, transmission, emission level and regional market.

Information to Collect Before Searching

Vehicle information

Vehicle manufacturer
Model
Production year
Engine size and engine code
Fuel type
Transmission type
Regional-market version

Controller information

ECU or TCU manufacturer
Complete controller family
OEM part number
Manufacturer part number
Hardware number
Software number
Calibration number where available
Processor or MCU where known

Required operation

Identification
Virtual Read
Physical Read
Calibration Write
Flash Read or Write
EEPROM Read or Write
Micro or MCU operation
Full backup
ECU or TCU cloning
Supported recovery

A clear photograph of the complete ECU or TCU label is normally the best starting point. Avoid cropped, blurred or reflective photographs that hide secondary numbers.

How to Search the KT200II Supported Vehicles List

Step 1Start with the exact ECU or TCU family

Enter the complete controller designation when it is known.

EDC17C64

MD1CS004

MG1CS001

DCM7.1AP

SIMOS 18

DQ250

8HP

Searching by controller family is usually more precise than entering only a vehicle manufacturer.

Step 2Compare the controller manufacturer

Confirm whether the result belongs to Bosch, Continental, Delphi, Denso, Marelli, Siemens, Keihin or the correct manufacturer for the physical unit.

Similar controller designations from different manufacturers must not be treated as interchangeable.

Step 3Check the processor

When multiple results share a similar ECU name, compare the Micro or MCU field. Processor information becomes especially important for Boot, JTAG and BDM operations.

Common database processor directions can include:

Infineon TC17xx
Infineon TC2xx
Motorola or NXP MPC
ST SPC
Renesas SH
Renesas RH850
ST10 and C167 families

The same processor does not prove that two ECUs use the same protocol. ECU family, hardware, memory and pinout must also match.

Step 4Combine keywords

When a general term produces too many records, combine the controller with a vehicle, processor or operation.

Audi EDC17 OBD

BMW 8HP

EDC17C49 TC1797

DQ250 BENCH

EDC7UC31 JTAG

Use a small number of precise terms. Adding too many words can hide a valid record when the database uses different abbreviations.

Step 5Check Read and Write abbreviations

Database notation	General interpretation	What to verify
R	Read operation	Which memory or file type is read?
W	Write operation	Which file and memory area can be written?
R/W	Read and Write are listed	Confirm whether operations are physical, calibration or memory specific.
VR	Virtual Read	Confirm what original software is provided and whether it is sufficient for the job.
VR/W	Virtual Read and Write are listed	Do not describe the Virtual Read as a complete physical backup.

The exact functions shown inside the current KT200II software and controller-specific protocol take priority over a general abbreviation.

Step 6Confirm the connection mode

The database may list one or more programming methods. Review the official KT200II Operation Modes page before preparing the job.

Mode	Connection concept	Main preparation
OBD	Communication through the vehicle diagnostic connector	Stable battery support and correct vehicle conditions
Bench	Direct connection to the ECU or TCU connector	Verified power, ground, ignition and communication wiring
Boot	Processor-level access that may require opening the ECU	Exact board diagram, Boot point and controlled power sequence
JTAG	Direct processor communication through dedicated points	Correct adapter alignment and stable board-level contact
BDM	Background Debug Mode access on selected controllers	Correct pad orientation, adapter and processor support

Step 7Confirm the available memory data

Do not stop after finding R/W beside the controller. Determine which data the supported protocol actually provides:

Calibration
Internal Flash
External Flash
EEPROM
Micro or MCU
Password or protocol data
Full backup
Dedicated Clone data

A tuning operation may require only calibration data, while cloning or recovery may require several physical memory areas.

Broad Search vs Precise Search

Search style	Example	Expected result
Too broad	Volkswagen	Many unrelated ECU and TCU records
Better	Volkswagen EDC17	Narrower Bosch diesel ECU results
More precise	Volkswagen EDC17C64	Results focused on the controller family
Operation focused	EDC17C64 OBD	Records associated with the requested connection direction
Processor focused	EDC17C64 TC1797	Results narrowed using controller and MCU information

What to Do When No Result Appears

A zero-result search does not immediately prove that the controller is unsupported. The term may not match the spelling or abbreviation used in the database.

Check the spelling on the physical ECU label.
Remove spaces, punctuation or unnecessary words.
Search the controller family without the vehicle name.
Try the family prefix before the complete suffix.
Search the processor or MCU.
Search the ECU or TCU manufacturer.
Reset all active filters.
Send the complete label and required operation to official support.

For example, if a long vehicle and ECU query returns nothing, try the exact ECU family alone before concluding that no protocol exists.

Never select the nearest-looking protocol after an unsuccessful search. Similar names can represent different processors, memory structures and connection diagrams.

Does “Supported” Mean Every Function Is Available?

No. A database record indicates an available protocol direction for the listed controller. It does not automatically mean that every possible operation is supported.

A record can provide:

Identification and Virtual Read
Physical Read and Write
Calibration-only access
Flash and EEPROM access
Processor-level backup
A dedicated cloning operation
One connection mode but not another

Confirm that the exact function needed for the customer job appears in the current protocol.

Virtual Read vs Physical Read

Read type	General meaning	Main limitation to check
Virtual Read	Obtains matching original software through the supported software workflow rather than reading every byte physically from the connected ECU.	May not include vehicle-specific EEPROM, Micro or complete recovery data.
Physical Read	Reads data directly from a supported memory area in the connected controller.	The result still must be verified for completeness, repeatability and memory type.
Full backup	Protocol-specific collection of memory data intended to provide deeper coverage.	Confirm exactly which regions are included instead of relying only on the label.

Use the correct terminology when organizing files. A Virtual Read stock file should not be mislabeled as a physical original or complete backup.

How to Check Support for ECU Cloning

Cloning normally requires more data than calibration programming. Before purchasing a donor ECU, verify:

Whether a dedicated Clone operation is listed
Which original memory areas can be read
Which donor memory areas can be written
Whether Flash, EEPROM and Micro data are required
Whether the donor hardware is compatible
Whether separate vehicle coding or adaptation is required

A matching connector and file size are not enough to confirm donor compatibility.

How to Check TCU Support

Use the TCU category or search the gearbox controller directly. Useful search terms can include:

DQ250

DQ500

8HP

TCU BENCH

After finding a result, compare the transmission application, TCU manufacturer, controller family, processor, memory and connection mode.

Programming a replacement TCU may not complete vehicle coding, initialization, clutch learning or gearbox adaptation. Those procedures can require a separate diagnostic platform.

Check the Protocol Before Opening an ECU

Opening a controller unnecessarily increases the risk of cover damage, circuit-board damage, contamination and sealing failure.

Use the following selection principle:

Use OBD if the required supported operation is available through OBD.
Use Bench when direct external-connector access provides the required data.
Use Boot only when the exact operation requires deeper processor access.
Use JTAG or BDM only for the supported controller and processor procedure.

Best practice: Choose the least invasive supported mode that provides all data required for the job.

Prepare for Programming After Confirming Support

A matching database record is the beginning of the workflow, not permission to write an unverified file.

Before connecting

Photograph the complete ECU or TCU label.
Open the controller-specific KT200II protocol.
Review the exact connection diagram.
Prepare stable vehicle or Bench power.
Check the required adapter and cables.

Before writing

Save the electronic identification.
Read every useful original memory area.
Protect an untouched master backup.
Verify the file source.
Compare hardware and software information.
Confirm the memory operation and exact file size.
Confirm checksum handling.
Prepare a recovery procedure.

Common KT200II Support-List Mistakes

Mistake	Why it creates risk	Better approach
Searching only the vehicle brand	The brand may use hundreds of controller variants.	Search the exact ECU or TCU label information.
Selecting the first similar ECU result	A suffix or processor difference can change the protocol.	Compare the complete controller and MCU.
Assuming R/W means full cloning data	The available operation may cover only one memory area.	Check Flash, EEPROM, Micro and Clone functions separately.
Assuming every supported ECU works through OBD	The listed procedure may require Bench or Boot.	Read the connection-mode field.
Using an old copied support list	Coverage and database presentation can change.	Use the live official KT200II finder.
Buying a donor before checking compatibility	Matching housings can contain different hardware.	Compare part numbers, hardware and processor first.
Writing immediately after finding a record	The file and memory operation may still be incorrect.	Identify, back up and verify before Write.
