Tuning potential
Fiesta ST potential depends on generation, engine, turbo, ECU and hardware.
Relevant engines: 1.6 EcoBoost; 1.5 EcoBoost
The Ford Fiesta ST has used different turbo petrol engines across generations, so the engine and factory output must be confirmed before tuning. S7 Remaps provides mobile ECU tuning across Preston and Lancashire, with the vehicle checked before programming and the calibration matched to its exact specification. Your registration can be used to confirm the engine and ECU before quoting a figure.
Engine codes and ECU
1.6 EcoBoost, 1.5 EcoBoost. The exact ECU and software version should be confirmed before programming.
Turbo and supporting hardware
Mk7 and Mk8 use different turbo and cooling arrangements; intake and intercooler condition matter.
Gearbox and clutch considerations
The manual gearbox and clutch should be checked before increasing torque. A worn clutch can slip once additional torque is applied.
Stage 1 information
Stage 1 can improve response and mid-range on suitable standard hardware.
Stage 2 information
Stage 2 depends on generation and supporting intake, intercooler, exhaust and cooling hardware.
Economy considerations
Fuel use depends on fuel, route and how often performance is used.
Suitability and condition
Check cooling, boost, plugs, clutch and service history.
- Confirm 1.6 or 1.5 EcoBoost
- Check clutch
- Assess cooling and intercooler
