What is an ECU?

ECU Remapping - Mechanic in Dubbo - T & A Mechanical Services
Simply put, the engine control unit (ECU) is the computer, or computers, which collects information from all the car’s sensors and driver inputs. It uses this wealth of information to define the operation parameters for the engine and deliver the optimum output (engine performance). The ECU measures:
  • Exhaust gases
  • Throttle inputs
  • Ambient & engine temperature
  • Fuelling requirements
  • And much more!

What does ECU remapping do?

When your car comes out of the factory, it’s ECU, and by extension engine calibration, is set to deliver performance in a wide variety of operating environments and allow extreme tolerances. In other words, your vehicle isn’t optimised for your particular style of driving or your location. ECU remapping adjusts these factory settings in the car’s computer, tweaks the parameters and tables to meet your desired outputs—improving performance or economy in the process.

Many new vehicles might also have been ‘de-tuned’ to lower levels as the manufacturer may want to have varying power levels within their product range, while still using the same base engine. This means your vehicle may have a deep reserve of untapped performance which can be accessed through ECU tuning, still within the engineering tolerances built into the powertrain.

Using the latest technology, T&A Mechanical can use ECU remapping to modify:
  • Fuel pressure
  • Fuel injection timing
  • Ignition timing
  • Absolute boost & delivery
  • Throttle input maps
  • Torque limiting maps
These are just the beginning, there are thousands of other parameters we can adjust, allowing us to take full control of the vehicles systems and deliver a superior driving experience.

What are the benefits of ECU tuning or remapping?

Whether you’re on the road, at a track day in a high-performance race vehicle, or off-roading in a turbo diesel 4WD—ECU remapping can dramatically improve engine torque and power among many other things. At T&A Mechanical, we think it’s easily the most cost-effective modification you can make. By removing unnecessary engine restrictions and other adjustments ECU remapping can improve:
  • Power – up to 30% increase, depending on other modifications
  • Torque – improvements across the rev range & low-down drivability
  • Response – better throttle response times, reduced turbo lag
  • Diagnostics – helps analysis to resolve ongoing DPF & EGR issues

How do you do it?

The ‘map’ that ECU remapping refers to, is an industry term for a table of hexadecimal values stored by and accessed in the car’s computer. These tables store information relating to fuel usage, boost, injection timing and a host of other inputs that affect how the engine operates. How we actually access this data is through the On-Board Diagnostics (OBD) port.

Often working closely with engineers trained by the car’s original manufacturer, T&A Mechanical spends hours identifying and modifying the maps which control all the engine’s variables. These files are then developed and tested using our dyno and high-tech software to ensure the remap (the new tuning setup) delivers optimum engine performance, eliminating a lot of trial and error.


Can I revert my vehicle to standard tuning?

If, for whatever reason, you wish to return your vehicle to its factory standard tuning (or how it was before the remap), we always keep a secured version of the file as a backup. It’s simply a matter of replacing the tuned file with the original one—and we’ll do this at no extra cost to you.

Is there a warranty with this service?

T & A Mechanical offer a 30-day Total Satisfaction Guarantee. If you are unhappy with the results of the tuning, speak to us within 30 days and we will return your vehicle to standard (as explained above), at no cost. All of our team has undergone extensive training and has plenty of experience—that’s why we can offer this guarantee with complete confidence.
