Refund policy

Returns & Refund Policy

Last Updated: 10 July 2026

At JTMO Mapping, customer satisfaction is important to us. As we provide vehicle tuning, diagnostics and software services rather than physical goods, the following policy applies.

Vehicle Tuning Services

Due to the nature of ECU tuning and software modifications, completed services are generally non-refundable once the work has been successfully carried out.

If you experience an issue directly related to our workmanship or software, please contact us as soon as possible. We will investigate the issue and, where appropriate, make reasonable efforts to resolve it.

Diagnostics

Diagnostic assessments are non-refundable once completed, as they involve time, specialist equipment and technical expertise.

Where a diagnostic assessment is included free of charge with a remap or approved service, no separate diagnostic fee will be charged.

If tuning cannot proceed due to ECU compatibility, software limitations or pre-existing vehicle faults, a diagnostic or assessment fee of £50 may apply where previously advised.

Cancellations

If you need to cancel or rearrange your booking, please provide as much notice as possible.

If work has not yet begun, any deposit paid may be refunded at our discretion, less any non-recoverable costs already incurred.

Customer Responsibility

Customers are responsible for ensuring their vehicle is in suitable mechanical condition before any work is carried out.

JTMO Mapping cannot be held responsible for faults, failures or performance issues caused by existing mechanical, electrical or software defects that were present before our service.

EGR, DPF & AdBlue Services

EGR, DPF and AdBlue modifications are supplied for off-road, motorsport or other legally permitted vehicles only.

These services are not intended for vehicles used on public roads, and no refund will be given where a customer requests removal due to legal or regulatory requirements after the work has been completed.
