Mobile ECU remapping

Ford Fiesta,
woken right up.

Britain's little hero has always punched above its weight, and whether it's the EcoBoost, the TDCi or a full-fat ST, there's cheap thrills waiting to be unlocked. We bring the proper dealer-level tools to your door, give the little one some attitude, and keep your original file backed up so the whole thing's reversible.

Typical Stage 1–2 gains — up to

+50

bhp

+80

Nm torque

Estimated peak gain across Fiesta engines. Your car's figures depend on spec, year, fuel & condition — we quote honest numbers, never fantasy dyno bragging.

So, what's in it for your Fiesta?

Even the humble Fiesta gets sandbagged from the factory. Whether it's the 1.0 EcoBoost, the 1.5 TDCi diesel or the ST's 1.5 EcoBoost, Ford tunes them conservatively for every market, fuel quality and neglectful owner going — which leaves a tidy slice of performance untouched. Our job is to hand it back.

On the little EcoBoost turbo petrols and the ST, that's real, feelable pace — sharper throttle, more punch out of corners, the kind of cheap thrill that makes you find the long way home. On the 1.5 TDCi diesel it's more about mid-range torque, so it pulls cleanly without a downshift and often sips a touch less fuel when you drive it sensibly (we know, we know). Small car, big grin, either way.

We come to you, plug in genuine dealer-level tools running off a stable power supply, and back up your original file first so it's fully reversible whenever you like. DPF, EGR and any emissions kit stay put — intact, road-legal, MOT-safe. Gains vary by year, spec, fuel and condition, so we'll give you an honest estimate for your Fiesta instead of quoting some heroic dyno figure from a car that isn't yours.

The numbers (the fun part)

Standard vs remapped, per engine. Bars are scaled to peak bhp — the red is what you've been missing.

1.0 EcoBoost petrol (125 PS)

+25 bhp+40 Nm
Standard125 bhp / 170 Nm
Stage 1 (est.)≈ 150 bhp / ≈ 210 Nm

1.5 TDCi diesel (120 PS)

+25 bhp+50 Nm
Standard120 bhp / 270 Nm
Stage 1 (est.)≈ 145 bhp / ≈ 320 Nm

Fiesta ST 1.5 EcoBoost (200 PS)

Standard200 bhp / 290 Nm
Stage 2 (est.)≈ 250 bhp / ≈ 370 Nm

Stage 1: ≈ 230 bhp / ≈ 340 Nm · Stage 2 shown (needs supporting hardware)

Typical estimates for a healthy vehicle. Stage 2 needs supporting hardware (intake/exhaust/intercooler) — we'll only suggest it if your car's up for it.

The small print (yeah, yeah): always tell your insurer about a remap — it's a mod, and "forgetting" can sink a claim. If your Fiesta is still under manufacturer warranty, a remap can affect powertrain cover, so weigh it up first. We keep your original file backed up either way.

Questions you're about to ask

Will a remap improve my Fiesta's fuel economy?

It can, particularly on the 1.5 TDCi diesel and 1.0 EcoBoost with an economy-focused map. The extra low-down torque means you carry gears longer and use less throttle, which often shows up as a few more MPG on steady motorway driving. Drive it harder and you'll simply enjoy the extra pace instead.

Is a Fiesta remap reversible, and does it keep the car road-legal?

Yes. We read and store your original file before writing anything, so we can return the ECU to factory at any time. Our performance and economy maps keep the DPF, EGR and emissions equipment fully intact, so the car stays road-legal and MOT-friendly.

Do I need to tell my insurer about a Fiesta remap?

Yes, you should always declare a remap to your insurer, the same as any modification. It's usually a small adjustment, and being upfront protects your cover. We're happy to provide details of the work carried out for your records.
