Hi,
I would like to know what ECU system can be fitted to my 1985 SD1 efi to replace the existing flapper unit. I have been told that the flapper leaves a bit to be desired on the performance side of things, but am not sure what I should be looking at as a replacement.
Would something from a later 3.9 efi Rover such as a Discovery fit the SD1?
Any advice appreciated.
Regards,
