Thread: where to go for P38a spares

I was just trying to get MicroCat working so I could check.

I just looked up the parts catalogues for the details.


I really doubt the ECU would work. The P38 engine ECU communicates with the BECM for security reasons. The D2 doesn't have a BECM.
Saying that though, I have seen a GEMS engine ECU in a car without a BECM & Labtronx has a 'bypass' so the GEMS (not too sure about Thor) ECU can work in a car without a BECM.

Did the D2's come out with the 4.6 as standard anywhere in the world?

The parts listing I use shows a 4.6 crank in the D2 engine section:

Sorry it's a bit on the small side.




And Wiki confirms it too for 03/04MY but doesn't say where. I assume the US would have it though.

03/04 Discos on eBay USA are 4.6s.

I'm betting a NA 4.6 ECU wont play well in an AU spec car

Can you change the tune? NA would be high comp with o2 sensors.
