In for CustomPro remap software was this Audi R8. This is the 525ps (518 bhp) V10 version with the automatic gearbox. The owner of this car had just received the car back from the garage he bought it from, of course this meant the car had just been filled with half a tank of regular unleaded (95 ron). We asked the customer to fill the rest of the tank with Shell V Power (our closest 99 ron supplier) and he obliged, brought the car back and we began to tune it.
This car uses two ECU's, one for each bank of five cylinders. The information in each ECU is identical which means once you have read the master ECU, you can make the changes to the copy of that software and apply it to both ECU's. We performed 4 software revisions ensuring this car was perfect before it left, but it got to the point where we were battling against the ECU altering the ignition advance which was down to the 95 ron fuel.
We still ended with a fantastic result and the graph can be seen below.
Power gained: 45 bhp
Torque gained: 24 nm
