Here’s one of the very first Land Rover Defender Td5’s we remapped, back in with us at Alive HQ to see how it’s still performing after all this time, and to give it a refresh with our latest super clean tuning.

The Td5 was still running well, although a faulty crank position sensor was causing the engine to cut out at higher engine speeds. With a new, genuine crank sensor installed, we refreshed the mapping to improve its overall drivability and we also significantly reduced the visible exhaust smoke, making this super clean 90 look more socially acceptable.

Stewart also gives some details on how we strap cars down to our dyno, and also explains the lines on our dyno graphs and what they mean.
