Software upgrades:

With sport button on, engine is in the ''aggresive mode'' having 1.5 bar overboost, 1.2 constant and 0.85 at 6000 rpm. With sport button off there are many choices. It is recommended that the pressure is adjusted at 1 bar without oveboost, whereas at high rpms pressure is a little lower so that engine and turbocharger work safer. Also, throttle response can be adjusted differently with sport button on and off.

Track use:
In this case, the setup is the same as Stage 1 with different ECU mapping. The overboost function is turned off so that pressure is constant at 1.3 bar from low rpms until 5000 rpm ending up to 1.05bar at revlimit. This results to less torque output (27 Kgm) in order not to have excessive Wheel spin. Also left foot braking function is turned on so that expert drivers have better control of the Car!

At last the OEM mapping of the Abarth 500 SS can be installed, since they share the same mechanical components except the ECU mapping.

All above upgrades apply to Abarth 500 SS as well.

Boost control is achieved using the OEM ECU and N75 valve

Use of 95/100 octane fuel is mandatory
