Trusted by leading brands
KESS V2 Master — Fast OBD2 ECU Remapping
OBD2 Read/Write for Cars & Light Trucks
Ideal for everyday tuning jobs.
KESS V2.80 V5.017 reads and writes ECU maps directly through the OBD2 port, so you usually don’t need to open the ECU. Perfect for stage 1/2 remaps, EGR/DPF off (where legal), speed limit changes and more.
EU Red PCB with Upgraded Components
Better stability and safer flashing.
The European-spec red PCB uses quality components (BCR112, NUP2105, BC817, BC807, etc.) for clean power delivery and strong communication, reducing the risk of interruptions during programming.
Wide Protocol Coverage with Anti-Tuning Protection Handling
Supports thousands of vehicles.
The latest K-Suite software includes expanded protocols for many ECUs and can handle numerous ECUs with anti-tuning protection, giving you access to more vehicles than older clones.
No Token Limit & “Online” Working Capability
Work without counting operations.
KESS V5.017 is an unlimited token Master version, so you’re not restricted by usage counters. It can work while the PC is online, but you must never run official online updates on the tool.
KTAG V7.020 — Bench & Boot Programming for Tough ECUs
Bench/Boot/TRICORE/BDM Support
Reach ECUs that OBD tools can’t handle.
When OBD programming is blocked or unsafe, KTAG V7.020 allows direct connection on the bench using TRICORE, BDM, JTAG and BOOT modes for full access to internal flash and EEPROM.
Multi-Platform Vehicle Support
Cars, trucks, tractors, motorcycles & boats.
From passenger cars to heavy-duty trucks and agricultural machinery, KTAG supports a wide range of ECUs from Bosch, Siemens, Marelli, Denso, Delco and more — ideal for mixed-fleet workshops.
Safe Read/Write with Recovery Function
Minimize the risk of bricking ECUs.
Automatic checksum correction, battery voltage monitoring and recovery functions help restore ECUs in case of problems during writing, provided a proper backup file is available.
Unlimited Tokens & Stable Red PCB
Designed for intensive professional use.
With no token limits and improved red board hardware (4-LED version), KTAG V7.020 is built for daily use in tuning shops where reliability is crucial.
