The ECU designed for
Yamaha YFZ450R Sport ATV
 
Yarara is the plug & play ECU developed by AiM for being installed on the Yamaha YFZ450R. Thanks to its high technology 32-bit core, it is a good help for improving the performances of your ATV, without sacrificing reliability and smoothness.
Yarara is specifically designed for:
Yamaha YFZ450R Model year 2021 and 2022
 
High technology 32-bit core
Engine control requires precision.
At 10,000 RPM Yarara guarantees a precision of 1/10 of degree: this means an accuracy within 1.6Ásec 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 exact result
A perfect reactivity at every minimum change
of any point of a map and, at the end…
More power
