What is it?

ECU flashing is the process of adjusting the settings on a motorcycle engine control unit (ECU) to suit the rider’s preferences. There are several different approaches to flashing. One approach is to flash the ECU with basic adjustments, such as increasing the RPM limiter, then using a piggyback controller, like a Power Commander, to make finer changes to fuel and spark tables to improve performance. The second approach is to make all changes in the flash which negates the need for a piggyback controller. At TL Tech we can do either, however, we use a hybrid approach, i.e. we make subtle changes to limiters, fuel, and spark tables. If more precise adjustments are needed, we can setup remote tuning using an interface on the customer’s ECU. If you are interested in remote tuning, please contact us. Our flashing and tuning services are for racing and off-highway / off-road use only, we follow all applicable environmental laws and we do not disable emissions controls.

Supported ECUs for Tuning and Flashing

Flash the ECU on your Yamaha, Suzuki, Honda, or Kawasaki motorcycle and get the benefits of:

  • Increase engine rpm limit
  • Remove speed limiter (racing applications)
  • Improved throttle response
  • Faster acceleration
  • Eliminate exhaust popping
  • Prevent lean fuel conditions due to increased airflow

What settings can be adjusted?

Late model ECUs have more features than older ECUs. The settings that are available for adjustment depends on the ECU. Here is a list of settings that can be changed by flashing a typical late model ECU:

  • RPM and speed limiters
  • Traction control settings
  • Fuel and spark tables for each power mode
  • Exhaust valve and air intake valve opening/closing
  • Idle RPM, fan temp switch
  • Quickshifter/auto-blipper control
  • Launch control, pit speed limiter
  • And much more!
