ECU Service Functions

ECU service includes 2 major items:

1. Chip Tuning: Chip tuning is to improve engine performance by modifying the data read out by the equipment. The data is divided into:

• Stage 1
• Stage 2
• Stage 3

2. ECU Maintenance: ECU maintenance data is to repair software errors in the ECU and some identity data of the ECU by modifying the data read by the device. Items include:

• DTC code Removal
• EGR & DPF Removal
• IMMO OFF
• Releasing speed limit
• Mileage correction
• Hot start or Cold Start Vmax

Stop Turning Away Jobs. Start Tuning the Untunable.
The KT200II (Generation 2) is not just a hardware refresh—it is a complete protocol revolution. Engineered for professional tuners who demand access to the latest locked ECUs without the risk of opening them.

Whether you are fixing a VW DCM6.2V in Europe, tuning an Isuzu D-Max in Thailand, or deleting AdBlue on a Kubota tractor in South Africa, the KT200II gives you the power to say "Yes" to every customer.

 2026.01 Massive Protocol Update (Exclusive to KT200II)
The old KT200 cannot do this. Upgrade now to unlock these high-profit services.

1. VAG Delphi DCM6.2V: Real Read via Pinout (No Open/No Risk)
Forget dangerous Virtual Reads (VR) that might not match the car's actual software version.

The Breakthrough: KT200II can now perform a Real Read of the full flash and EEPROM directly from the ECU pins.
Why it Matters: Essential for safe VAG 1.6/2.0 TDI tuning and perfect cloning. No need to break the factory seal or struggle with VR file mismatches.
2. Isuzu & SAIC Bosch MD1CS089: Full Bench Mode
The locked ECU found in the 2021+ Isuzu D-Max (RZ4E/4JJ3) and MG Extender is finally cracked.

Capability: Read/Write Micro + EEPROM completely on Bench.
Application: Perfect for DPF/EGR/AdBlue removal and Stage 1/2 tuning in Southeast Asian and Australian markets.
3. Agricultural Giant: Kubota Denso AdBlue Unlock
Servicing farm machinery? The new Kubota Denso 2760xx driver allows you to fix critical AdBlue failures on tractors and skid steers (like SVL97).

Function: Full Read/Write via Bench for AdBlue off solutions, keeping farming equipment running without costly downtime.
4. FCA TPROT V14 Protection Bypassed
Tuning 2021+ Fiat, Jeep, and Alfa Romeo models (ME17.3.0 / EDC17C69) used to be impossible due to the new TPROT V14 RSA signatures. KT200II bypasses this automatically in Bench mode.

 Key Features from 2024 Updates (Included)
VAG FRF/SGO Downgrade: Restore VW/Audi ECUs to pre-dieselgate firmware to unlock OBD read/write capabilities or fix software bugs.
Mercedes 9G-Tronic Cloning: Exclusive Bench driver for VGS-NAG3 transmission. Clone expensive TCU units without online SCN coding.
PSA SID807/EVO Real Read: Safety first. Read the actual data from Peugeot/Citroen via OBD instead of relying on risky server files.
 Why Choose the "Full Version" with Offline Workstation?
For tuners in regions with unstable internet (Nigeria, South Africa, Vietnam), the Offline Dongle is a lifesaver.

Black USB Key: Offline Software.
White USB Key: Hardware License.
Benefit: Tune trucks on the roadside or tractors in the field with zero internet connection required. (Note: Dongle requires online reactivation only once every 15 days).

 What's in the Box?
KT200II Master Unit (Blue PCB with NXP Smart Chip)
Offline Workstation Dongle (White) + Software Key (Black)
