In our latest dyno test we have this 2012 Audi A3 in for stage 3 custom ECU mapping. We adjust the software and fine tune the results from the rolling road dyno testing, to really maximise every part of the rev range. The result… Some pretty impressive performance gains!!
Now it was already running stage 1 mapping. But had since had a few hardware modifications, including a hybrid turbo and a Pipercross induction kit. So firstly, we take the A3 with its current mapping and get it strapped up on to the rollers, conducting the first set of tests to establish what the current mapping is producing. You can see the results of this below. You can see that power and torque are running at 183hp with 414Nm of torque. These are dialled in, so we know exactly what base we’re working from.
Once we are happy that we have everything logged and the base figures entered, it’s time to connect to the ECU. We use our Autotuner system to connect directly on to the ECU. The process of this custom tune is very much a hands-on, ‘fine tweaking’ procedure. We make several alterations to the software, adjusting the exact parameters we need and configure the software files to give us that increased power and torque. Once we are happy with our alterations, we take it for further dyno testing, allowing us to monitor the engine responses in real time, data logging the entirety of the test.
Once the first few tuned runs are complete, the data is analysed and conclusions can be made as to where further adjustments and alterations can be made. Again, we configure this directly within the ECU, changing the exact parameters which are necessary to reach the requirements.
After these adjustments, there are further tests and it’s once again taken for more tuned runs. The data is logged and gains are recorded. This process is repeated several times, as we will constantly analyse and fine tune, right down to the final requirements, until we are happy that we are getting the very best results from this remap.
The final tuned dyno run can be seen at 0:38 in the video below, where we have finally finished altering everything, giving us the complete results. Dyno testing before and after shows healthy gains across the rev range, with a significant increase in power and torque, really transforming how it feels to drive.
Peak power was increased significantly. We were able to lift it from 183hp, up to 239hp after the custom tune. Taking a look at the tuned dyno graph below you can see how the curve changes (dotted red and blue lines), bringing that power in right down from those lower revs, and showing improvements across the whole rev range. We give real consistency here, really opening up that mid-section, right up to that top end where we provide that additional +56hp at its peak, really transforming how it feels out on the road.
Torque also saw huge improvements. With the current mapping the engine produced 414Nm, and now 477Nm after the remap. Again, taking a look at the graph (solid lines), you can really see the difference in that curve. You can really see that consistency, where we hold those gains across the entire rev range, delivering those increases exactly where it’s needed, adding that +63Nm at its peak.
