Is a remap worthwhile on a car of this age?
It depends entirely on engine condition. On a well-maintained example the DTi responds well, but remapping does not compensate for wear.
How does this differ from the other Vectra entries?
This covers the B generation specifically. Our history records the model under several designations, so check them all.
Do you work with these older ECUs?
Yes, the EDC15 and SIMTEC units of this era are covered in our catalogue.
