hi i need your help with my 2.0 16v. I need an ecu (well im still waiting for confirmation which i should get within a couple of hours) so if anyone has one that would be great. But i also need to know if i need the ecu mapped of anything changed at all even if its second hand, im pretty sure the garage will need to do something to a brand new one but don't know what. Also if i could find a chipped one would that make a difference, and if you have one for sale that would be great.
Any numbers or web pages would useful.
the cars a 88/89 f reg astra gte 16v although i think any ecu from a non-cat engine would work.
