What is the 2.4 JTD five-cylinder?
It is the largest diesel in the range, with a distinctive delivery and considerable torque. It is the most worked engine on this model.
Is a remap worthwhile on a car of this age?
It depends on engine condition. A well-maintained JTD responds well, but remapping does not compensate for wear.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
