Hi all new to the site.

I have a 3.2 V6 Gsi in a calibra which im running off a 3.0 superchipped omega Ecu as the connections are the same for the calibras loom.

I have asked loads of places about mapping to obviously get the fully spec from the engine but i have been told i need to have the ECU for the engine for the original software for the 3.2

Im not sure what year vectra the engine was taken from and also would it matter if i just purchased a 3.2 ecu so i can get a base Ecu map to start from when i get remapped.

My current ECU chip will need to be replaced or a writeable chip put in as it is currently unreadable by remapping devices.

Any info or help will be great.
