Terms of use: ECU Tuning Gain Results
Estimated power gains provided in relation to a particular vehicle variant on the ECU Tuning Page, are estimates based on what has been achieved previously. Customers purchase the Add On or remapped file, rather than the achievement of a specific power (BHP or NM of Torque) figure. Refunds will not be issued solely because a vehicle has not achieved a specific BHP or NM of Torque figure.
Data logs may be requested from the customer when investigating issues reported by customers. VJ’s Auto Clinic reserve the right to suspend investigation into a customer issue or complaint if the log data is not supplied by the customer.
Where a customer is submitting a third-party opinion relating to the use of a SOFTWARE file, VJ’s Auto Clinic reserves the right to request a written report and details of the organisation / company providing the report, as well as contact details of the author for verification purposes. Third party opinions can only be considered from sufficiently experienced / qualified and VAT registered vehicle garages, specialists, and tuning workshops.
VJ’s Auto Clinic is an authorised dealer of “Max Tune Software” and reserve the right to refer customers to other authorised “Max Tune Software” dealers.
Where the customer has commissioned a third party to complete additional work to rectify a suspected software fault with VJ’s Auto Clinic product, no payments will be made by VJ’s Auto Clinic to cover the work performed by a third party.
Where refunds for Add-Ons or files are due, a refund will not be issued where the vehicle has not been returned to stock (standard) first by an authorised DEALER.
Where refunds are due and issued, it may take up to ten full working days for the refund to be processed and reach the customer’s account. This is largely due to third party secure payment system provider timescales. Refunds will be issued to the payment card used to make the original purchase payment.
Vehicle Status, Mechanical / ECU Issues and Faults
ECU SOFTWARE is used by the customer at their own risk. VJ’s Auto is not responsible for any damage to a vehicle, or faults following the use of the ECU SOFTWARE.
When tuning / remapping / modifying a vehicle, the customer is likely to be asking more of the vehicle to achieve increased performance. Customers should be aware that any underlying mechanical issues could become more apparent or be exacerbated once a vehicle is tuned / remapped. These issues may not have been noticeable previously.
Customers and vehicle owners are responsible for ensuring that their vehicle is in good condition, well maintained and mechanically sound before and after any tuning / remapping / modification work.
VJ’s Auto Clinic is not liable for any issues with a vehicle or ECU where the customer has failed to put in place the necessary supporting hardware modifications for the remapping option they have chosen. The customer is responsible for ensuring they have the correct, high-quality modifications in place prior to using a remapping option that requires supporting modifications.
VJ’s Auto Clinic is not responsible for any issues where a vehicle ECU has been opened or tampered with previously by a third party. The customer is ultimately responsible for their ECU (and any resulting issues) if they use the ECU SOFTWARE, or any other tuning / remapping tool, or an ECU has already been opened, tampered with, or damaged previously.
If a vehicle has significant Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR), or Petrol Particulate Filter (PPF) / Gasoline Particulate Filter (GPF) related issues, these issues must be resolved before remapping the vehicle. Customers should be aware of this.
The customer is responsible for checking their vehicle tyres before using ECU SOFTWARE. Customers must ensure that their vehicle tyres are in good condition and (as a minimum) road legal prior to remapping their vehicle. This primarily for safety reasons.
The use of good quality fuel is very important for a tuned / remapped vehicle. If poor quality fuel is used, maximum power gains are unlikely to be achieved. Customers should be aware of this before using the ECU SOFTWARE. If further information is required regarding fuel, customers can approach VJ’s Auto Clinic for further advice.
Any information provided related to the ECU SOFTWARE is based on the assumption that vehicles being remapped are in good condition, well maintained and free from any mechanical / ECU issues. The customer should be aware that a basic diagnostics scan / diagnostics session may not identify every potential problem with a vehicle. Customers wishing to procure more in-depth diagnostic or health check services have the option of contacting VJ for advice prior to purchasing ECU SOFTWARE.
An ECU performance remap designed to increase performance will not resolve existing mechanical issues with a vehicle (in isolation). Customers should be aware of this before remapping a vehicle or using the ECU SOFTWARE.
Gains in fuel economy are only likely to be achieved where a vehicle is in good condition, well maintained and free from any mechanical and ECU issues. Gains in fuel economy will also only be achieved when driving the vehicle conservatively.
Customers that want confirmation / documentation of their vehicle’s power figures (at stock and / or after tuning) should contact VJ’s Auto Clinic prior to purchase. VJ’s Auto Clinic may be able to offer a Dyno Session, depending on location.
Although very rare, ECUs can fail when any software is written to them, or at any other time. Customers should be aware of this very small, but real risk. VJ’s Auto Clinic is not responsible for any incidents of ECU failure.
Where there is evidence of previous water damage to an ECU, the customer is advised not to use the ECU SOFTWARE.
VJ’s Auto Clinic is not liable for any issues with a vehicle or its components where advice provided by VJ’s Auto Clinic has not been followed by a customer. We recommend that advisory points (where provided) are followed up as soon as possible.
Should a customer discover a suspected fault with a ECU SOFTWARE, related equipment, or software, the customer should contact VJ’s Auto Clinic as soon as possible. Please note that software faults and issues with the map / directly caused by the remap are very rare. Where they do occur and are genuinely caused by a remap, a customer will notice very soon after the remap has been completed (when driving the vehicle).
VJ’s Auto Clinic is not responsible for investigating or correcting suspected vehicle faults where the customer, or a third party, has worked on / interfered with the vehicle, its components, ECU, or the SOFTWARE provided since the vehicle has been remapped.
VJ’s Auto Clinic is not responsible for correcting suspected vehicle faults.
Diesel Particulate Filter (DPF) Services
The DPF Delete software solutions offered by VJ’s Auto Clinic are intended for vehicles that have a the physical DPF filter removed and are not driven on public roads.

VJ’s Auto Clinic is not responsible for checking vehicle use / purpose.
Any DPF Removal and Delete services provided are done so at the independent request of the customer. The customer is fully responsible for their decision to have the DPF removed and deleted on their vehicle(s) and / or install any relevant DPF software solutions.
VJ’s Auto Clinic does not encourage the use of the DPF Removal and Delete service for vehicles used on public roads. Any customers choosing to remove and delete a DPF on a vehicle for use on public roads, do so at their own risk.
Customers must ensure that the physical DPF filter has been removed fully and properly before selecting and using a DPF Delete software solution. VJ’s Auto Clinic is not responsible for any vehicle issues associated to customers selecting the incorrect software options for their vehicle’s set up. Where further advice is needed, customers can contact VJ’s Auto Clinic in advance of purchasing SOFTWARE.
Decat Services
Decat software solutions offered by VJ’s Auto Clinic are intended for vehicles that are not driven on public roads. For example, race vehicles, track day cars and vehicles driven on private land. It is legal to provide decat services. However, driving a vehicle on public roads with a decat performed is illegal. Having a decat will mean that the vehicle concerned will not pass a standard MOT. VJ’s Auto Clinic is not responsible for checking vehicle use / purpose.
Decat services and / or related software solutions are provided at the independent request of the customer. The customer is fully responsible for their decision.
Petrol Particulate Filter (PPF) Removal and Delete Services
Petrol Particulate Filter (PPF) / Gasoline Particulate Filter (GPF) Removal and Delete and / or software solution services, offered by VJ’s Auto Clinic are intended for vehicles that are not driven on public roads.

Petrol Particulate Filter (PPF) / Gasoline Particulate Filter (GPF) Removal and Delete services and / or related software solutions are provided at the independent request of the customer. The customer is fully responsible for their decision.
‘Pop and Bang’ Options
‘Pop and Bang’ has become an increasingly popular option in terms of remapping. Customers should be aware that ‘Pop and Bang’ is not possible with all vehicle variants. For further advice customers can contact VJ’s Auto Clinic prior to purchase.
A full decat is required before a ‘Pop and Bang’ remap is completed. This is necessary in order for ‘Pop and Bang’ to be safe for the vehicle and prevent damage to the vehicle. Customers should only apply a ‘Pop and Bang’ remap if the vehicle concerned already has a decat. A Lambda Delete software solution is also likely to be needed. Decat services are intended for vehicles that are not driven on public roads. VJ’s Auto Clinic is not responsible for checking vehicle use / purpose.
Supporting Hardware Modifications and Performance Parts
Some SOFTWARE options will require minimum hardware modifications to be in place prior to remapping, or the application of the Add On (file). The customer is responsible for ensuring that their vehicle has the correct modifications in place, that all work has been completed to a high standard, and that all parts used are good quality.
VJ’s Auto Clinic is not responsible for compromised vehicle performance or running capability due to insufficient or poor-quality supporting hardware modifications completed by the customer or a third party.
Some vehicle modifications, and the software solutions available for them, are intended for vehicles that are not driven on public roads. VJ’s Auto Clinic is not responsible for checking vehicle use. Customers are responsible for their own choices regarding vehicle modification and for checking that any chosen modifications are legal and appropriate for the vehicle and the uses of the vehicle.
Any estimated performance / power gain estimates provided are usually based on the use of tried and tested performance parts previously used by VJ’s Auto Clinic and sourced through trusted suppliers. Where alternative parts are used by the customer, we may not be able to provide power gain estimates.
Power gain estimates are based on an average of what has been achieved previously. However, a range of factors can affect the BHP and NM of Torque figures and increases achieved. Post remap performance can vary from vehicle to vehicle. At Stage 2 and beyond the variances can be greater, as the modified set up of the vehicle, and the need for impeccable maintenance of the vehicle, become even more important.
When modifying a vehicle, you are likely to be asking more of it in terms of performance. Customers should be aware that any underlying mechanical issues could become more apparent or be exacerbated once a vehicle is tuned. These may not have been noticed before. VJ’s Auto Clinic is not responsible for underlying mechanical issues with a vehicle.
If choosing to opt for a Stage 2 (or beyond) Remap, customers should expect increased maintenance of the vehicle going forward.
