This is my first post and its for help. I have just imported an XJS 5.3 Convertible from the UK to Australia.
The car is in super condition having only done 63k miles.
my problem is the car has no catalytic converters so need to upgrade. after weeks of reading I’m a little more informed but more confused. From what I have read my car will be comp ratio 12.5:1 but need a DAC 4585 ecu which is from the 11.5 engine. Which they say fits but should not be used on that engine. However elsewhere it says this ECU can be modified and indeed some did come with engine management sensor links. So which direction do I go in.
Then having determined this point I need some additional harnesses and or wiring modifications. I have ordered the Jaguar Electrical manual but again experiencd is better than reading.
The Cat I think will be the easy bit thats assuming no body work difference between models.
Finally can any body give me a contact to purchase the NINE LIVES CD.ROM as I have had no success so far.
