Is a remap worthwhile on a car of this age?
It depends entirely on engine condition. On a well-maintained example the DTi units respond well, but remapping does not compensate for wear.
What is the 2.5 TDi?
It is the BMW-sourced six-cylinder diesel fitted to some Omega versions. It is present in our catalogue.
Do you work with these older ECUs?
Yes, the DDE, EDC15 and SIMTEC units of this era are covered in our catalogue.
