Fiat/Abarth 124 Spider TMC Motorsport ECU Performance Software Calibrations

TMC Motorsport Performance ECU Software – Abarth & Fiat 124 Spider

Give your Scorpion the love it’s always deserved with TMC Motorsport’s expertly developed ECU Performance Software.

With over 25 years in the tuning industry – and more than a decade dedicated to the 1.4 T-Jet and Multiair engines – we’ve fine-tuned our calibrations to deliver impressive gains without sacrificing drivability or long-term reliability.

🧠 Why Choose TMC Performance Software

Our software is developed entirely in-house by our team of specialists. For many models, we offer home flashing via Powergate 4, giving you the freedom to tune your vehicle from the comfort of your own garage. With years of testing and refinement behind every map, our calibrations are built for reliable performance, not just peak power.

⚙️ Software Options Explained

TMC Stage 1
No hardware upgrades are required for Stage 1. However, if your vehicle is fitted with an upgraded intake (such as ITG, Forge Motorsport, BMC, DNA Racing or similar), this can be factored into the tune.

TMC Stage 2
Designed for cars with additional hardware, Stage 2 requires modifications such as a high-flow downpipe, performance intake, and uprated intercooler.

TMC Bespoke – Price on Enquiry
Our Bespoke software is for setups that go beyond Stage 2 — including inlet manifold scaling, camshaft lift tuning and more. Please contact us to discuss your build and receive a tailored quote.

🏠 Home Flashing with Powergate 4

Powergate 4 is our preferred handheld programmer that allows you to reflash your ECU from home. The tool arrives ready for your tuned and original files, and the interface is simple to use.

Once your original ECU map is read and sent to us, we’ll return your tuned file within 1–3 working days.

If you prefer to send us your ECU, we recommend Royal Mail Special Delivery or DHL Express with insurance. Return postage (insured) is included in the cost.

Shipping charges are fully covered when selecting the Home Flash Tool option.

The Powergate app is compatible with the most widely used smartphone operating systems: iOS, Android, and EMUI, offering an intuitive tuning experience through vehicle performance customization. Once paired with the smartphone, it allows access to modified files on the Cloud.

⛽ Fuel Requirements

You must run a minimum of 97 RON fuel with all of our ECU calibrations. We recommend using 99 RON (e.g. Shell V-Power, Tesco Momentum). If 97+ RON fuel is not available in your region, please contact us before purchase.
