Unichip ECU 


"Power without compromise, that's what we like to see".  

Fast Fours and Rotaries Magazine  


The flexibility of the Unichip Engine Control Unit (it's a fully functioning computer, not just a chip) has to be seen to be believed. With 408 adjustments, perfect engine tune is achieved at all RPM and at all throttle positions. The Unichip ensures maximum torque, power, instant throttle response and good fuel economy. 

Unichip now available with MY01/MY02 plug in loom

Importantly, the Unichip ECU works in harmony with the factory ECU. That means cold starts are never a problem and engine protection is never compromised with fully functioning air temperature compensation and knock sensor control. Unichip is designed to work in conjunction with the standard ECU self learn facility for optimum engine efficiency under light throttle cruise conditions.

The MY01 EFI system is very advanced and in general has far greater control over EFI parameters than previous models. APS has developed a completely new Unichip utilizing 3 CPUs instead of the previous model's single CPU. This gives the Unichip tuner the ability to finely optimize the EFI strategy for optimum performance.  

Any performance enhancement such as a bigger turbocharger, intercooler, or free flowing exhaust system, demands the Unichip. You won't get the maximum benefit from your modifications until the Unichip is fitted and tuned for your engine. 

Also available with the Unichip are exciting options such as: 

  • computer managed boost control for optimized boost levels throughout the entire rev range.
  • Auxiliary injector control for high horsepower applications where up to 4 auxiliary injectors can be driven.
  • computer controlled intercooler water spray for additional charge air cooling when the engine really needs it. Will be mapped against boost pressure and engine RPM.
  • dual ignition maps for operating with different fuels or road/race applications.
