Car remap preparation checklist: 10 essential checks
1. Make sure there are no warning lights
The first job is simple: check the dashboard. An engine management light, DPF light, glow plug warning or any other active warning should be investigated before remapping.
Modern vehicles constantly monitor sensors, boost pressure, fuelling, emissions systems and exhaust temperatures. A warning light may point to something minor, but it can also indicate an issue that affects how the engine performs under load. Adding more torque to a vehicle with an unresolved fault is never the sensible route.
If a light has come on recently and then disappeared, mention it anyway. Stored fault codes can still provide useful information during a diagnostic check.
