Petrol ECU Tuning
What benefits will I get from ECU tuning and remapping a turbocharged petrol engine?
Turbocharged petrol 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 waste-gate (turbo boost pressure control).
After your ECU upgrade to your turbocharged petrol engine, you will enjoy:
- Increased horsepower
- Increased torque
- Better throttle response
- Smoother power delivery
- Safer overtaking
Improvements in fuel consumption on petrol engine vehicles are smaller and nothing like that achieved by diesel vehicles.
What benefits will I get from ECU remapping a non-turbocharged petrol engine?
The normally aspirated petrol engine, whilst not being the easiest of engines to tune, can still benefit from a 8-15% power increase with added torque by careful reprogramming of various engine parameters within the map. Parameters such as the fuel and ignition curves can be fine-tuned to give better power & torque output. On some engines the camshaft timing can also be tuned within the map, giving additional improvements.
In many cases, 'after market' tuning items such as freer flowing exhausts, high flow air filters and re-profiled camshafts can only be fully utilised by the engine once the necessary adjustments have been made within the ECU. Careful re-calibration of the correct maps can unlock the potential of your new engine parts. Further power gains may also be available when a higher octane fuel is used, allowing for more ignition timing.
