It controls the amount of fuel that enters in the cylinder by changing the fueling injection. The ECU is easy to set up and it interfaces with the original gear case. The programming is intuitive. You can download the software to run the Engine Control Unit from www.polini.com website, “technical area” section. The Polini ECU, thanks to the original sensor located in the air filter, acquires the data, and it sets itself automatically according to the weather condition.

It is available in two models:
– Model for TMax 500
