The uk  standard 3.2 has electronic throttle, different coil packs and no egr. All which make a difference to the ecu used?

You obviously swap those parts from the 3.0 on the 3.2.

I guess you could say you take the 3.2 long block and put the rest of the parts from the 3.0. So essentially a 3.2 on a 3.0 ECU.
But yeah you are kinda right, I wasn't specific enough heh.

The 3.2 engine itself on mine is from a 2004 Vectra.

And loom, and TCM (if auto), and reconfig ABS.  Not just a straight ECU swap

The fuelling requirements between a 3.0 and 3.2 are reasonably similar, if you put in a bigger FPR, or let the trims drift to richen.

Well ok it's not an ECU swap because I have the 3.2 long block in my 3.0 Omega, if you want to be picky about it lol. So a long block swap!

I think what stige, is saying he has a 3.2 block, with 3.0L heads, etc in a 3.0L,

If he has the above in a 3.2, then he either has late 3.0L heads on with holes for coil packs, or has tapped holes for coil packs.
And the 3.0L ecu doesn't work in 3.2L as TB said it's the wiring, totally different, loom.

I'm almost sure the heads are 3.2, everything else is from the 3.0 except the long block.
This is long block:

Long block is an automotive term for an engine sub-assembly that consists of the assembled block, crankshaft, cylinder head, camshaft (usually), and valve train. A long block does not include fuel system, electrical, intake, and exhaust components, as well as other components (see below for a more complete list).

.

So in plain English, you've put a 3.2, into a 3.0L, and using 3.0L throttle bodies.

I thought it was plain english when I said long block

 I'm use to a short engine, or a fully dressed engine, or bare engine.

Calm down opti.

[Doctor Gollum]

Bare engine then

Basically a slightly stroked 3.0 as far as the electrickery is concerned

You British people and your weird terminology

Well I popped open a 2.5 manual ECU and Anhialator sent me a pic of the innards of a 3.0 auto and both main chips have different ID numbers so as stated they are different, I do believe either will run the other engine but possibly not without issues

No, you're absolutely right:


Short block: assembled block, crank rods, pistons, oil pump and sump - basically everything below the cylinder heads. These are often available exchange from your dealer.
Long block: as above but up to the cam covers and including the cam belt and flywheel/flex-plate. These are also dealer supplied.
Fully dressed: all the covers, manifolds, accessories, belts, sensors etc. This is done by fitting your parts to one of the above.

Even if the internals look the same, the configuration loaded onto the ECU might well be different.

2.5 and 3ltr ecu's are nigh on identical   
Only the 3ltr one has slightly more fuelling right at the top end 
A few years ago, I ran a 3ltr lump with a 2.5 ecu with no problems at all until I sourced one off Lincs Rob

What were the trims doing? As I'd  expect the fuelling to be different across the rev range

Mmmmmmmmmmmm   Fair comment
