FIAT remapping gains; improved BHP and Torque.

Remapping the Fiat 500 X (2015-2018), 1.4T MultiAir 140HP.

The Fiat 500 X (2015-2018)'s 1.4T MultiAir 140HP sees a torque-led Stage 1 remap: pulling power climbs 17.4% to 270Nm, well ahead of the 7.1% rise in BHP from 140 to 150.

Turbocharged petrol engines have plenty of scope for a Stage 1 remap, and this impressive improvement is best felt through sharper throttle response across the rev range. These figures apply to 2015-2018 models.

Questions about remapping your 500 X 1.4T MultiAir 140HP

How much power and torque does a Stage 1 remap add to the Fiat 500 X (2015-2018) 1.4T MultiAir 140HP?

A Stage 1 remap typically takes the Fiat 500 X (2015-2018) 1.4T MultiAir 140HP from 140bhp to around 150bhp, and torque from 230Nm to around 270Nm. This is a impressive gain achieved entirely through software, with no hardware changes required.

Is the Fiat 500 X (2015-2018) 1.4T MultiAir 140HP a good candidate for remapping?

Generally, yes: as a turbocharged engine it has the headroom to respond well to a quality remap, and the impressive gain shown here reflects that. The main caveats are condition, not the engine itself, a healthy service history, no outstanding fault codes, and (for diesels) a clear DPF and EGR are what actually determine whether this particular car is ready for a remap.

Will remapping affect the warranty on my Fiat 500 X (2015-2018)?

A manufacturer can only void the parts of a warranty that the remap directly affects, not the entire vehicle, under the Consumer Rights Act and EU Block Exemption principles. In practice, on a Fiat 500 X (2015-2018) 1.4T MultiAir 140HP this usually means engine and transmission-related claims are the ones worth discussing with a reputable tuner before booking.

What should I check before booking a remap for my Fiat 500 X (2015-2018) 1.4T MultiAir 140HP?

Before booking, confirm the tuner uses a custom or bespoke file rather than a generic off-the-shelf map, ask whether they do a pre-remap health check, and check service history and mileage on your specific Fiat 500 X (2015-2018).

What's the difference between a Stage 1 and Stage 2 remap for the 1.4T MultiAir 140HP?

Stage 1 is software-only and is what the figures on this page reflect. Stage 2 builds on that, but on a turbocharged engine like this, Stage 2 usually adds further gains but requires supporting hardware such as an upgraded intake or exhaust, so it is a separate conversation with a tuner rather than an automatic next step.

Will remapping my Fiat 500 X (2015-2018) affect my insurance?

Yes, always, a remap is a modification and must be declared to your insurer regardless of size. Given this impressive gain on the 1.4T MultiAir 140HP, expect a likely premium increase, and it is worth getting a quote from a specialist modified-vehicle insurer before booking the remap itself.
