FLAWLESS Performance Flash - KTM - EXC
The FLAWLESS ECU Performance Flash for the KTM EXC optimizes the software of the original engine control unit – for the two-stroke EXC 125, 150, 250, and 300 models with TPI and TBI. The result: more power and torque, cleaner throttle response, and smoother behavior in the partial load range. Every software optimization or flash for your KTM EXC is individually tailored to your vehicle and configuration – no off-the-shelf maps. Developed in-house and Made in Germany.

How do I know if my KTM EXC is TPI or TBI?
The two models differ in their injection system: in TPI, the injectors are located in the transfer ports, whereas in TBI, they are in the throttle body. TBI was introduced with the newer model years, while TPI is found on the older models. Both systems use different engine control units, which is why there is a specifically developed optimization for both TPI and TBI.
