KESS & KTAG Devices What are KESS and KTAG devices? They are devices for copying and programming car engine control units (ECUs). These programmers copy the computers or extract the software from the engine computer itself. For example, if you brought a used or new car computer and replaced the car's main computer, will the car work? The answer is no. What is the solution? You need to transfer or copy the original software and transfer it to the new computer. You can do this through these programmers by transferring the complete software or transferring the operating information, key information [EEPROM]. Then the car will work. When using these programmers, we do not need online subscriptions to program the ECUs. We just copy the old one to the new one, and that's it. These KESS and KTAG programmers also help us extract the software if we want to modify the car's software. For example, if we need to disable a system, disable a fault, disable the key code, increase torque, unlock speed, program for fuel saving, and many other things. The programmers help us extract the original software and rewrite the modified software.
