REMAPPING TERMS AND CONDITIONS
Please read this information carefully before booking a remap.
Thank you for choosing Fast Road Tuning to carry out your engine remap. We are dedicated to bringing you a quality service with which you are fully satisfied. However, it is your responsibility to read and understand the following points.
By booking your remap with us, you are accepting these terms and conditions.
Expected improvements
All power, torque, and MPG figures quoted and shown on our Remap Calculator are estimates/expected gains based on our extensive experience and prior testing (sometimes at dyno centers). If you dyno your vehicle after our remap without having a dyno before, you accept that without an original figure (baseline), the final outputs cannot be questioned.
The gains you experience depend largely on your vehicle’s condition at the time of remapping/testing. The quality of fuel used in your vehicle can also make a significant difference in the gains achieved.
The percentage gains for fuel economy are stated as averages and may vary from car to car. Many external factors affect MPG figures, such as driving style, fuel grade, tire pressure, ambient temperature, altitude, etc. Fast Road Tuning cannot be held responsible if your vehicle does not meet the expected MPG gains.
Where we dyno test your vehicle before and after your remap, the purpose of the figures is to show the power and torque improvement (both peak and “under the curve”) from the baseline test (before tuning). All tests will be completed with the highest level of repeatability possible, but since every dynamometer has different tolerances, calibrations, and correction settings, Fast Road Tuning is not responsible for the final figures. As such, dyno test results may vary from estimated gains on our Remap Calculator.
Warranties and liabilities
If you choose to remap your engine or transmission, you do so wholly at your own risk. Fast Road Tuning does not provide a warranty on your vehicle. If your vehicle has over 100k miles on the odometer, we reserve the right to decline to remap it.
Remapping sometimes emphasizes underlying issues already present in a vehicle’s engine or transmission. For example, while a vehicle may not have any known problems or show any faults on the dashboard or during our Pre-Tuning Health Check, it may have a component approaching the end of its serviceable life. This will not be outwardly evident to the customer or to Fast Road Tuning. Applying a remap may cause a component to fail sooner than it would have otherwise. No refunds or liabilities will be provided for any such problems after a remap.
We take every precaution to minimize risk, but in the extremely unlikely event of an ECU failure during the remapping process caused by an external factor outside our control, Fast Road Tuning cannot be held responsible or liable for any costs. For example, an unexpected power outage/surge.
The software warranty covers you for software re-installation in the event of a fault in the code, valid only during your ownership of the vehicle (non-transferable). Fast Road Tuning will make the final decision if the code is faulty, and we do not accept third-party opinions. If our remap is inadvertently wiped by a software update applied by a garage or dealership, we can reapply the remap at a flat rate of £99. Where a software update has applied an OBD lock or tuning lock to the ECU, Fast Road Tuning is not responsible for removing this lock. Additional costs to remove the lock will apply, charged per hour with a minimum charge of £50.
If we need to remove any components to gain access to your OBD port or ECU/module, we will take the appropriate level of care, but Fast Road Tuning is not liable for any damage that inadvertently occurs. As the vehicle owner, you are responsible for the underlying condition of your vehicle. For example, removing a plastic scuttle panel at the base of your vehicle’s windshield, which is commonly poorly refitted or previously damaged during windshield replacement.
Where an ECU security cage needs to be removed to reprogram your ECU in bench or boot mode, an initial fee of £30 will be payable, and £30 per hour for additional time spent.
If your vehicle has a warranty, you are responsible for checking if a remap will invalidate all/part of your warranty. Fast Road Tuning accepts no liability for a voided warranty after we have installed a remap or after we have installed any parts you request us to fit to your vehicle.
30-Day No Questions Asked Money Back Guarantee
If you are unhappy with your remap or change your mind for any reason, our 30-Day No Questions Asked Guarantee entitles you to a full refund if you instruct us to remove the remap and return your vehicle to the factory ECU calibration. The guarantee commences on the day of remapping and expires 30 days after. For example, if our remap was added on the 1st day of the month, it expires at 11:59 on the 30th day of the month. Any claims beyond the 30 days will not be considered. Beyond 30 days, the Software Warranty applies.
Exclusions:
Cars with over 100k miles on the odometer are not eligible for the guarantee.
This guarantee is not valid if your car was previously remapped, as we may not be able to reapply the other tuner’s software.
This guarantee is not applicable to stage 2 or custom remaps.
This guarantee is not available for emissions solutions.
This guarantee does not cover any claims for damage to your vehicle during the 30-day period.
Existing condition of your vehicle
As the current owner of the vehicle, you confirm to the best of your knowledge that there are no pre-existing faults/mechanical issues with the engine or vehicle that may hinder or affect the remapping process or its subsequent reliability. We carry out a Pre-Tuning Health Check (visual inspection, full diagnostic scanning, and data logging where supported by your ECU) before commencing work, but this doesn’t always show every fault in the vehicle. It is your responsibility to disclose any such issues before work begins.
If your vehicle has an automatic transmission, we will perform a diagnostic check for any faults logged in the memory of the transmission control unit, but Fast Road Tuning is not responsible or liable for any issues related to the gearbox or transmission that may be revealed after an ECU or TCU remap. It is your responsibility to ensure the transmission has been serviced according to the recommendations of the gearbox manufacturer or specialist (not the dealership) and is in fully working order. Clutch slip in a manual transmission vehicle is possible after a remap if the clutch is nearing the end of its usable life or due to an aggressive driving style. Fast Road Tuning is not responsible for any clutch wear or slip you might experience. We will advise you when an upgraded clutch is required.
As the current owner of the vehicle, it is your responsibility to know its past history and whether it has been modified or remapped before Fast Road Tuning works on it. If you know it has been modified or remapped, you must inform the Fast Road Tuning remapping agent when booking. In the very unfortunate event that a previous remap causes ECU failure, triggers limp mode, or reveals a hidden fault, Fast Road Tuning will not be held responsible.
For the benefit of both parties, we reserve the right to refuse to work on a previously remapped car, and in this situation, the deposit will not be refundable. If we remap your vehicle, and it becomes apparent during the final test drive or data logging that it was already remapped, the remaining balance will still be due since we have completed the work you instructed us to. If we must source original software (known as an “ori file”) to remap your vehicle due to non-original ECU software, this will be charged extra.
If a previous remapper applied a tuning lock to your ECU, and it cannot be remapped by us (the lock cannot be overwritten or removed), the original full balance is still due.
In the unlikely event of a new or undiagnosed problem presenting itself immediately after we have reprogrammed your ECU, we will endeavor to resolve this through software changes by remaining onsite/continuing to work on your car for a reasonable timeframe. However, if we deem the issue is unrelated to our work, you may be charged for our time and be wholly liable for the costs of any third parties we hire on your behalf to resolve the issues.
We strongly recommend you test drive the vehicle after the remap. If you are unable to, or choose not to, test drive the vehicle with the Fast Road Tuning engineer present, Fast Road Tuning cannot accept any liability for faults or issues found after the engineer has left. If you request we return to the vehicle for troubleshooting after the job is completed, you will be charged a £50 call-out fee and a further £50 per hour.
Emissions solutions
If your vehicle has a factory-fitted emissions system, you should not modify it to reduce its effectiveness. Our emissions solutions are intended for off-road use only. We advise of this during the sales process, in the invoice, and in the vehicle condition report. You accept all potential penalties that may result from driving a vehicle on the road with a modified emissions system(s).
If you bring your vehicle to our premises for an emissions solution, we advise you to organize a vehicle recovery truck or trailer to relocate your vehicle afterward.
A missing or modified DPF, EGR, or catalytic converter (where one was fitted when the vehicle was manufactured) can result in an MOT failure. By instructing Fast Road Tuning or a third party to remove or modify any of the above, you accept all potential penalties.
If you instruct us to remap or apply an emissions solution to your vehicle when the engine cannot be started due to a fault or electronic engine lock, Fast Road Tuning cannot be held responsible for any engine management lights present once the engine is running again.
In some cases, your vehicle may need to be recovered to a dealership to remove an electronic no-start lock. Fast Road Tuning is not liable for any associated costs.
Booking and Payment
Clients must book appointments in advance by speaking with us on the phone.
A 20% deposit is always required to make a booking, and we will specify a deposit due date to secure your chosen date. If you do not pay your deposit by the deposit due date, your appointment time will become available to another customer.
Your deposit is non-refundable, irrespective of any change in circumstances before or on the day of your appointment. If you fail to attend your appointment or are more than fifteen minutes late without notifying us, your deposit will not be refunded. If we deem your vehicle unfit or unsafe for remapping after our Pre-Tuning Health Check, your deposit will not be refunded.
You may reschedule your remap but must provide at least 48 hours’ written notice.
Any refunds for deposits or purchases made through our website will have 3% deducted due to merchant fees.
If you financed your remap through PaymentAssist, any refunds issued by us will be less due to merchant fees.
Any supplier-related fees Fast Road Tuning incurs will also be deducted from your deposit.
Final payment is due upon completion and collection/return of your vehicle. We will not release a vehicle with an outstanding balance.
Modification of Terms
We reserve the right to modify these terms and conditions at any time and without notice.
