Frequently asked questions
What tuning stages are available for JCB?
Most JCB engines support Stage 1 (software-only) remapping, and many also support Stage 2 once supporting hardware (intake, exhaust, intercooler) is in place. Availability depends on the exact engine — you'll see which stages apply once you get to the engine's performance page.
How long does JCB ECU file work take?
Most files are turned around in a few hours once uploaded through the member panel, though it depends on the ECU and how busy the queue is. You can track the request's status in real time from your account.
Is remapping safe for my JCB?
Every file is worked individually by someone experienced with that engine family, not matched against a generic archive. Stage 1 in particular is designed to stay within the engine's mechanical safety margins.
What do I need to send for a JCB file request?
Your original ECU file, read with a compatible tool, plus the vehicle details (model, generation, engine) so the right base file and stage options are offered.
