If you are the owner of a Volkswagen Up, Skoda Citigo or any other 1.0-litre car, then you’ll know that these machines are excellent for navigating towns and cities and can more than hold their own on the motorway. But, you’ll also know that they need an awful lot of revving and gear changes to really get moving. These cars are obviously not about speed, however more torque and power would no doubt improve the driving experience, right?

The truth is, remapping a car with a small displacement may not really be worth it. But, it may be worth it if your car has forced induction, such as with the Ford Fiesta 1.0 EcoBoost or Vauxhall Adam 1.0 Turbo. We’ve written in-length about the pros and cons of having an naturally aspirated car remapped, and our view is that a smoother power band and a freer revving engine makes remapping worth it – but customers won’t be blown away by the results in the same way that they would be after a forced induction car has been tuned, as a 5-10% increase in power and torque is the limit that can be extracted from a remap.

Having said that, if you want to benefit from increased throttle response and better overall performance, then by all means get your 1.0 naturally aspirated car tuned.

Hyperchips knowledge base: “If your car is pre-2000, remapping your car will not be possible as back then there was no standardised way of reading and writing an ECU (OBD).”

Instead, if you are the owner of 1.0-litre naturally aspirated car and you want to extract more power out of it, you could be better off carrying out engine performance mods, such as cylinder head upgrades and spark plug upgrades. Such performance modifications will increase your car’s power potential and will enable tuners to extract better performance.

Now, if you are the owner of a 1.0 turbo, petrol or diesel, then a remap will be one of the best things you ever did. This is because the turbocharger’s boost can be increased safely on top of fuelling parameters. The result will be an increase in power and torque of 20-30%. To put that into perspective, our Ford ECU remapping service for the Ford Fiesta 1.0 EcoBoost increases power from 123bhp to 154bhp and torque from 147 lb /ft to 181 lb /ft. Those are huge gains that will be extremely noticeable during every day driving.

Perhaps the main reason you are considering getting your 1.0 car remapped is not for power, though – perhaps you want to improve its economy. To this end, remapping is a great way to get more miles out of a tank of fuel. The way this works is simple – with more power and torque, your engine doesn’t have to work as hard shifting weight. This saves fuel, and because your car will respond better from low revs, you can drive in a higher gear more of the time, which again saves fuel. Basically in like-for-like driving, a car will have better fuel economy after a remap because your engine and you won’t have to work as hard.
