The first job of the day in Porthtowan was this brilliant little Fiat Abarth 595 1.4 Turbo, our very first of this specific model — though we’ve tuned dozens of other Fiats over the years.
At Kernowsport, we always enjoy working on performance-oriented vehicles, and the Abarth range never disappoints. Small, light, and punchy, this little hot hatch has loads of potential — especially when paired with the right remap.
ECU Tuning: When OBD Just Isn’t Enough
While the Abarth 595 uses a relatively common Bosch ECU, it turns out it can’t be tuned via the standard OBD port alone. Instead, it requires what’s known as a bench method ECU modification, where the ECU is safely removed and connected directly to our professional tuning equipment.
Although this might sound complex, it’s actually one of the safest and most reliable ways to work with an ECU. It allows us to create a complete backup before applying any performance changes — meaning the vehicle can always be restored to factory settings if needed.
For this job, we used our Alientech Kess 3 tool, though we also keep our Magic Motorsport Flex available for vehicles that require alternative communication protocols. This flexibility means we can handle virtually any car, van, or even HGV that comes our way.

Results: A Punchier, Sharper Abarth
After reading and modifying the ECU file, we uploaded a Stage 1 performance tune tailored specifically for this Abarth’s 1.4 Turbo engine. The results were immediately noticeable — quicker throttle response, stronger mid-range pull, and a sharper overall driving experience.
The owner was thrilled with the results, describing the improvement as “night and day.” That’s what we like to hear — another satisfied Kernowsport customer!
Why Bench Tuning Can Be the Better Option
Bench tuning may take a little extra effort, but the benefits are worth it. By connecting directly to the ECU, we ensure:
- ✅ Full data access for a safer and more precise tune
- ✅ Reliable backup before flashing the new file
- ✅ Compatibility with vehicles that OBD tools can’t read
- ✅ Reduced risk of communication errors or failed writes
If you’re thinking about a remap on a modern performance car like the Abarth 595, bench tuning may be the best route for you.
