Tuning The Land Rover Defender - A 2012 Land Rover Defender on the dyno at Alt Tune

2012 Land Rover Defender

2.2L turbo diesel – Continental SID208 ECU

The Challenge

The Land Rover Defender gained a worldwide reputation for ruggedness and versatility. It has kept those qualities throughout the years even though the engine and design have been updated many times. The 2012 Land Rover Defender’s are installed with a 2.2L Duratorq engine that, even smaller than the former engines, still keeps up with the same power and torque output.

In this blog post we are looking into how tuning the Land Rover Defender can improve its performance. We had a customer come in with a 2012 Land Rover Defender. The customer felt that the car was sluggish and underpowered. We are going to use this 2012 Defender to illustrate the gains that a custom tune from Alt Tune can give.

The Solution

We decided to give the Defender a power tune to give the customer the extra pep they were looking for. We used Alientech KESS3 to flash the custom power tune into the Defenders Continental SID208 ECU. So, what exactly is flash tuning and how does it work? Flash tuning is a process where the ECU of your vehicle is reprogrammed to optimize the performance of the engine. By re-writing the tuning file in the software, the ECU parameters that govern things like fuel delivery, and boost pressure are changed and optimized to extract more performance from the engine.

We did a dyno test after we had flashed the tune. This is to ensure that the vehicle’s performance are optimized and that the engine’s reliability and longevity are maintained.
