High Technology 32-bit Core
Engine control requires precision. At 20,000 RPM the Yarara ECU guarantees the precision of 1/10 of the degree: this means an accuracy within 0.8 uses for turning the spark ON!
This precision is the key to guarantee :
A very consistent engine rotation.
The possibility to repeat dozens of tests at the bench, always obtaining the same result.
A perfect reactivity at every minimum change of any point of a map, resulting in more power at the wheel.
UC Bridge Tuner - Optional Extra
The UC Bridge is the connection between the CAN bus of the ECU and the USB port of your PC.
Tuner License :
This is the Tuner that is required to configure the unprogrammed Yarara ECU.
With this license, the tuner can create different maps, configurations and strategies. The tuner can then flash them directly onto the ECU or send them via email to allow the rider to download and install them in the ECU.
*Please Note: For information regarding the UC-Bridge Tuner, please contact one of our AiM technical team for further information.
