The VW Golf MK7 R is currently one of the best everyday road cars available in the UK. We knew it would become a very popular car for tuning and aftermarket parts, so we purchased our own Golf R Estate for research & development.
The MK7 Golf platform is fitted with the latest generation 2.0TSi engine is controlled by the Simos 12 & 18 ECU, similar to the Golf GTI.
First we performed a quick health check using our diagnostic testing equipment and then put the vehicle through a set of stock dyno runs and data logging. Data logging the engine in standard form allows us to understand every aspect of the ECU. Our first data log and dyno run and revealed the engine was making 310BHP at the flywheel with 400Nm of torque, up 20Nm over manufacturer figures. After checking the existing map we could see that Audi had set the torque to 400Nm.
Carefully analysing the recorded data logs we started re-calibrating the engine ECU data for a Stage 1 tune. Our aim was a safe 360bhp and 460-480Nm tune using standard engine components.
Using our specialist ECU programming equipment we wrote the newly developed software to the ECU. We then preformed a post tune data log to ensure everything is reacting well to the new map.
For this tune, we wrote between 30-40 different maps applying fine adjustments to make the perfect tune. It’s this meticulous attention to detail demonstrates the care we take when producing each one of our maps.
