Toyota claims 0 to 62mph in 5.5 seconds for the 261PS GR Yaris (2020 to 2023), and 5.2 seconds for the 2024 facelift, which was lifted to 280PS. The engine is the G16E-GTS, a 1.6 litre three-cylinder turbo, driving all four wheels through the GR-Four system. A Stage 1 remap takes the 261PS car to around 305PS and 400Nm on our rolling road, on standard hardware, which trims the 0 to 62 figure again and makes a much bigger difference to how it pulls out of a corner.

FAQ's

Motorsport-exclusive components are explicitly designed for track use. While they can be installed on any vehicle, it’s important to note that using such parts renders the vehicle unsuitable for road use and may result in MOT failure.
No! Our remaps are designed specifically to improve the performance of your vehicle whilst remaining within the tolerances of your vehicles’ components.
Sadly, in attempt to achieve ‘big numbers’ some other companies over tune engines, placing excessive stress on the engine, transmission, cooling systems, etc, leading to reduced life span and reliability of the vehicle. We pride ourselves in producing reliable remaps which do not over stress your vehicle but still produce impressive results.
In any case where a customer is dissatisfied with any ecu remap software supplied, within thirty days of the supply date, the customer can request their money back. In order for any refund to be processed, the customer must present their vehicle to our workshop and allow our technicians to restore the vehicle to its original state. On successful completion JF Automotive will refund the cost of the remap to the customer.
No refund can be granted unless the vehicle is returned to the original state by JF Automotive. The 30-day money back guarantee only applies to stage 1 remaps and does not apply to other services like pops and bangs, parts or dyno sessions.
If another modification is purchased alongside a tuning file, which relies on a remap to operate, only the cost of the file is covered by this guarantee. We reserve the right to withdraw this 30 day money back guarantee.
Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.
No problem, simply bring the vehicle back in and we will take a fresh read of your ECU and write you a new map file free of charge. We offer this as part of our lifetime software support.
Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle. Many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased economy however a failure to disclose modifications may invalidate your policy. You may wish to enquire with your insurer if the modification will affect your policy prior to choosing one of our services.
We get asked, “Why do some tuners charge as little as £150?” There are a few factors as to why we do not offer remapping for £100-£200!
We supply custom written files for each vehicle that we remap that take in to account condition, milage and customer request of each vehicle. Our services are fully insured with a 30-day money back guarantee and lifetime support for the tuning software supplied. We constantly invest in the most up to date tuning and diagnostic equipment and software and we offer a quality service to all our customers.
Overall our custom supplied tuning software is of the highest standard that we know of, so if you want the best of the best, choose JF Automotive.
Questions we get asked
What is the GR Yaris 0-60?
Toyota quotes 0 to 62mph (100km/h) in 5.5 seconds for the 261PS car built from 2020, and 5.2 seconds for the 2024 facelift with 280PS. The 0 to 60mph figure is fractionally quicker than the 0 to 62 one, which is why you see slightly different numbers quoted.
What engine is in the GR Yaris?
The G16E-GTS: a 1.6 litre turbocharged three-cylinder, the most powerful production three-cylinder of its kind when it launched. 261PS and 360Nm in the 2020 car, 280PS in the 2024 facelift.
How much power does a GR Yaris make remapped?
Around 305PS and 400Nm at Stage 1 on our dyno, from a standard 261PS car, with no hardware changes. That is roughly +44PS and +40Nm, and the torque arrives earlier, which is what you feel on a road.
Is remapping a GR Yaris safe?
On a standard car with a healthy engine, yes. It is a small, hard-worked engine, so we do not chase the biggest possible number: the file is written to keep temperatures and knock margin where they should be, and we prove it on the dyno rather than on the road.
Does a remap affect the GR-Four four-wheel drive system?
No. The engine ECU is a separate unit and the centre coupling keeps working exactly as it did, including the Normal, Track and Sport modes. Nothing about how the car puts the power down changes.
Is it worth tuning a GR Yaris or should I buy the Circuit Pack?
They do different things. The Circuit Pack gives you the limited-slip differentials, suspension and wheels, which change how the car corners. A remap changes what the engine makes. If you already have the chassis you want, the map is the cheaper way to add pace.
