Diagnostics, datalogging and pre-remap health checks for cars that need answers before tuning, repairs or power testing.

Diagnostics & Datalogging Wigan

Diagnostics before tuning

A remap should not be used to hide a fault. Wraith Performance can check fault codes and live data before tuning so problems are found before extra load is added.

This is especially important on cars with unknown software, warning lights, misfires, clutch slip, boost leaks, poor service history or previous hardware changes. A healthy car gives a better result and reduces avoidable risk.

Identifying faults before remapping

Boost leaks, misfires, weak sensors, clutch slip, fuel pressure issues and poor maintenance can all stop a tuned car performing properly. A health check gives the best chance of a strong result.

The team can review scan data, live values and symptoms before advising whether the vehicle is ready for tuning, needs a repair, or should be datalogged under load.

Datalogging sessions

Datalogging records how the car behaves under load. This helps with low-power issues, cars not making quoted figures and vehicles with unknown previous tuning.

Logs may be used to review boost request, boost actual, ignition correction, air temperatures, fuelling, rail pressure, torque request and other values depending on the vehicle. That gives a stronger basis for decisions than guesswork.

Cars not making quoted power

If a car feels flat or has failed to make expected numbers elsewhere, a dyno and datalogging session can help narrow the cause and build a repair or tuning plan.

Common causes include heat soak, poor fuel, boost leaks, tired ignition parts, blocked intake paths, exhaust restrictions, slipping clutches, gearbox torque limits or previous software that is not suited to the hardware.

Low power investigations

Low power does not always mean the car needs a remap. Sometimes the best result comes from fixing the fault first, then tuning when the vehicle is stable and repeatable.

Wraith Performance can use diagnostics, road-style data checks where suitable, and Dyno Dynamics testing for FWD and RWD vehicles to understand what the car is doing under load.

What to send before diagnostics

Send the registration, fault symptoms, current modifications, any warning lights, previous dyno figures and when the issue happens. Photos or screenshots of fault codes can also help before the appointment.

The clearer the starting information, the easier it is to book the right amount of time and avoid turning a tuning appointment into an unexpected investigation.

Fault codes

Scan and live data checks before tuning decisions.

Under load

Dyno and datalogging checks for suitable vehicles.

Repair plan

Clear advice if the car needs work before tuning.

FAQs

Questions customers ask

Should I book diagnostics before a remap?

Yes if the car has warning lights, unknown software, poor service history, boost issues, misfires or feels down on power.

Can datalogging find low power issues?

Datalogging can help narrow the cause by showing how the car behaves under load, including boost, fuelling, temperatures and torque behaviour where available.

Can you fix faults found during diagnostics?

Wraith Performance can advise on mechanical repairs and next steps if a fault is found before tuning.

Can I book a dyno test for a low-power concern?

Yes, suitable FWD and RWD vehicles can be checked on the Dyno Dynamics 450DS with datalogging where required.
