Kwp2000 + Plus ECU Flasher Chip Tuning Tool KWP 2000 Kwp2000 + Plus ECU Flasher Chip Tuning Tool KWP 2000 Use this device you can READ and WRITE the flash data stored in the ECU. The stored data, called MAPS are responsible for things like injection timings, ignition advance, torque limiter, speed limiter and many more. By using this tool with the software provided you can read the MAPS and REWRITE the values to increase power and give you better fuel economy. Remapping a petrol engine ECU can produce 10 - 15% BHP depending on exact specification, the engine will also be more responsive on initial acceleration and produce more torque (up to 20%) through out the entire rev range, giving more response on lighter throttle. Remapping a petrol turbo engine ECU can produce 20 - 30% BHP depending on exact specification, the engine will be significantly more responsive with power coming in immediately relative to throttle input with no lagging at higher revs. This large increase in power & torque gives far more flexibility in all gears reducing the need to change down unnecessarily to overtake safely and quickly. Remapping a diesel turbo engine ECU can produce 30 - 50% BHP and 60 - 75% torque depending on exact specification, diesel engines give the most impressive power and torque gains available. Extra power is gained through out the entire rev range and under all load conditions, the turning force gained from these engines is imence. This really is the best way of changing your car without having to change your car.
