What’s the difference between tuning your ECU with Woolich Racing and using a piggyback fuel controller system?


A piggyback fuel controller system alters the signal after it has already been sent from the ECU to the fuel injectors.  A piggyback controller then requires a harness installation, piggybacking onto the fuel injector connector, in order to alter these signals.  This is then a hardware solution which ONLY modifies the fueling and nothing else.  As the ECU does not know that the fuel values have been changed by the piggyback controller it is unable to compensate for other effects that this might have on other maps such as requested torque, etc. 

Tuning your ECU reprograms the maps and settings at the source level inside the ECU, this provides a much larger feature set and finer control over the programming inside the ECU.  Writing a complete tune to your ECU then provides much greater flexibility, performance and ultimately power to tune your bike to the limit when compared with piggyback controllers.

Yes, writing to your ECU does also come with greater responsibility to ensure that it is written properly and reasonable map changes are made but all tuners are aware of this already. 

With a Woolich Racing ECU tune, maps are individually edited and optimized either by:

  • Woolich Racing Tuned AutoTune, which uses engine data and Air Fuel Ratio (AFR) to determine if your bike is running rich or lean
  • A professional dyno tuner who combines their personal experience with the use of a dyno, and can expertly tune the maps to suit your needs
  • The individual who owns the bike and knows it better than anyone. We provide a free Foundations Training Course to new customers to help them learn how to use our products and get started on tuning their own bike 

This will give you, hands-down, the best performance from your bike.
