The Fiat 500 Abarth Esseesse is a powerful car: Strong engine and lightweight – the perfect combination for a pocket rocket. But it can gain more power with an Etuners Stage1 ECU remap, on completely stock hardware. The 1.4TJet engine does not mind 95RON fuel either. Boost levels are increased by 0.2bar. Together with improved torque management and direct throttle pedal response, this software upgrade makes your 500 faster and much more responsive.

We provide upgraded software solutions for the 1.4TJET and the 1.4Multiair engines, which the Fiat 500 is equipped with, either for 95RON (91Oct) or 98RON (93oct) fuel.
