Cpu???

G'day all,

Have not long gone from a 3.0 litre (2002) to a 4.2 (2000) Was at the stage where I knew the 3.0 back to front, now have to start again with the 4.2. My question is though, when did they start using computers? Does the 4.2 have CPU? I am fairly sure that my model doesn't, its old school and believe me, after the 3.0 ending up in a ploom of smoke, I am loving old school.

Appreciate any feedback.

The TD42 does have an ECU but doesnt do much
Later TD42ti models have the fuel pump advance and egr running through one, they pick up a throttle position sensor and runs security system NATS too.
I just had a crook connector to advance solonoid give problems and I too was keen to go back to older model. Didnt stop but ran poorly, to give credit the ECU shut the solonoid off after a while and it drove fine just below performance

Cheers Jet, is a 2000 model 4.2 worth chipping? Would there be any advantage? What does the CPU do in this model?

Cheers,

Ty

Fuel pump is not electronic. Find a good diesel shop and get them to play with the pump and turbo to get best out of it.
