BENCH TUNING is simply remapping by another name, but involves the physical removal of the program chip from the main ECU in the vehicle and either re-programming or replacement with a new chip modified with a Quantum remap. Technology developments mean that Chip Tuning is rarer now, but is still the only way to programme certain vehicles. Nowadays most remaps are carried out via the diagnostic OBD2 Socket, or direct into the ECU using special adaptors on the bench.

OBD Remap

Three phrases that essentially mean the same thing are used within the vehicle remapping industry: “Chip Tuning”, “ECU Remapping”, and “OBD TUNING”. They all relate to the process of altering the parameters within a vehicle’s ECU to gain performance. “OBD Tuning” refers to the use of the vehicle’s diagnostic port to access the ECU code, rather than physically removing the control unit. Modification via OBD is the most common form of chip tuning.

When car warning lights illuminate on your dashboard, an engine diagnostics check can help identify the problem before more serious damage occurs.

Most modern vehicles today contain an on-board computer known as an Engine Control Unit (ECU) which continually monitors the performance of the vehicle. Sensors all around the vehicle report back to the ECU if there are problems such as low fluid levels or increased engine temperature. When an issue is identified the ECU generates an error code. The relevant dashboard warning lights will then be displayed.

DPF Clean

If you’re experiencing the following symptoms your DPF may need cleaning:

  • The DPF warning symbol has appeared on your car’s dashboard
  • Loss of power
  • The automatic stop-start system isn’t working
  • Poor fuel economy
  • Cooling fans run more than normal
