4.2 v8

[SILICONEKID345HP]

Can anyone tell me how the old 4.2 was made up and what fuel injection system is this ?

well that's a Jag AFM (XJS 4.2 Series III) as used on some of the fat wedges (including my 420SE)

It's likely to be a 4CU ECU, likely to also have larger injectors

you've also got 4.2's and 4.2's.........the classic range rover has a 4275cc 4.2 whilst the 4.2 (like in the SEAC) has a 4228cc

You'll need some bigger brains than mine to explain the difference lol........

Would that engine have a chip or could it be mapped ?

You want to have a chat with Mark Adams - he is an early flapper specialist and can make them sing and dance lol

He's currently testing, repairing and matching the Jag AFM to the ECU.....literally he's doing it today

Once done its rolling road time to get it all set up

He did say he can tweak the ECU, even make it adjustable if I recall the conversation correctly
