OEM ECU tuning

OEM ECU Tuning

Not full-on track racing and heavily modifying your car? We can tune your factory ECU to get more out of your vehicle on the street. 

We can tune your OEM Bosch, Siemens, Transtron, Delphi, Delco and many other ECU’s.

You won’t need to buy any new parts, just get in touch and we can walk you through the steps to upgrade what already works in your vehicle.

Reflashing is a technique that allows modification of the factory engine management map through the vehicle’s diagnostic (OBD2) port. This allows us to alter the factory ecu mapping the same way that the factory engineers do it. There is no wiring required, none of the factory components are removed or changed and the factory map can be returned to stock at any time if required.


  • Cost Effective – No need to spend thousands of dollars on a standalone ECU. Reflashing uses the hardware you already own.
  • Discreet/invisible modification – There are no wires to cut, no sign that your ECU has been modified and you can always return to your stock map at any time.
  • Retain factory driveability – With a reflashed ECU, your car will drive and start just like stock. This can be difficult to achieve with some standalone ECUs.
  • Retain Factory Safety Features – Reflashing retains factory safety features such as knock protection, active knock control and dual octane maps for fuel and ignition timing. Great for peace of mind!
