Flash Remapping (ECM)
OBD REMAPPING BENEFITS FOR TURBOCHARGED ENGINES
Turbocharged engines have always been regarded as the sports flagship engine for good reason. They boast far higher power & torque figures than a non-turbocharged power-plant with similar displacement and are usually fitted to the manufacturer's flagship models. They are also ideal candidates for remapping as the ECU also controls the wastegate (turbo boost pressure control).
After your ECU upgrade via OBD or direct to ECU flash to your turbocharged engine, you will enjoy:
- Increased horsepower
- Increased torque
- Better throttle response
- Smoother power delivery
- Safer overtaking
WHAT DO YOU ACTUALLY MODIFY IN MY VEHICLE?
We do not change any hardware in your vehicle, we just modify the operating parameters in the ECU's program or MAP. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and the casing opened, our technicians will then use specialist tools to read the original map straight from the processor chip.
We then will then upload the original map to our editing software then adjust the parameters to maximise the performance, fuel economy or a clever blend of both. Depending on the vehicle and ECU type the reprogramming process can take under an hour and if at any time you wish to return your vehicles ECU to its original default settings, this can be done easily and free of charge as we always keep a copy of the original software as a backup.
SAVING FUEL WITH OBD REMAP?
When we remap a vehicle, especially when fuel saving is the priority we focus on improving the low end torque in particular and widening the power-band as far as we can.
This increase in low end torque will mean less throttle pedal input is required to maintain cruising speeds, when fully laden or when on a gradient. It will also mean that the vehicle will be more comfortable in higher gears at slower speeds as well requiring fewer gear changes overall.
If you combine these factors with adjusting your driving style to make the most of the extra low end torque you will see an improvement in fuel consumption. This is most effective on turbo-diesel engines where the savings could be as much as 20%!
