Engine Stage 1
If you are not already aware, power figures on Rolling Roads are part measured and part calculated. For the purpose of this article we will be showing Flywheel and Torque figures. One last point worth mentioning is that both peak figures (regardless of measurement) and to a degree even full graphs of delivery do not tell the whole picture. How the car responds and drives on the road in real life driving scenarios, is equally as important. As and when (when applicable) we will also be driving the car and testing on the road during major steps in the Engine Modifying process, to get more feedback and information.
STAGE 1 – ENGINE MODIFICATIONS
Re-mapping
For this stage of testing and comparison we will be looking primarily at bolt on modifications, with the exception of ECU remapping. Any ECU mapping will be completed using the standard OEM ECU in conjunction with the ECUTEK software, this allows access and change of the ECU parameters as desired. For obvious reasons this needs to be done professionally by people that know exactly what these changes mean and what they will affect. With this in mind, ECU re-mapping will be undertaken by Powerstation.
The standard ECU on newage Impreza’s is incredibly flexible and comprehensive. It was not that long ago that the only way to achieve full control over various parameters, was to purchase an aftermarket ECU, primarily one aimed at the motorsport market. Luckily for us and with the development of ECUTEK this is no longer an issue for our level of modifications. This is all good news for us guys, as it means we can then spend our money on other things!!
For the majority of us we don’t really care what this side entails. As long as we get the expected results who cares what parameters have to be changed and for what reason……but equally there are a number of us who are interested.
The black art of engine management has moved from the old days of physically changing ignition and fueling, by means of spanners.... now a new tool is being used.... the all powerful Laptop!
