As title really, will a 2.5 run with. 3.0 ecu and vice versa?

[biggriffin]

Will work fine,   

Something's telling me immobiliser?? Might be a problem.
 .


I've done 3.0L into 2.5L worked fine, gearbox (ar35) worked with 2.5 gbox  Ecu.

[JamesV6CDX]

Yes

[zirk]

There not all the same, PFL,MFL, FL, but I cant remeber which for which now.

[Stige]

I also have 3.2 with 3.0 ECU and works just fine, the differences are so small.

Not without other drastic changes you haven't

It'll need recoding to match config.

Yep, I recall the TPS wiring being completely different with some 2.5s which causes "issues".

What changes? Only difference is bore and stroke, nothing else. It works just fine with a 3.0 ECU with such tiny difference.

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.

[biggriffin]

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.

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'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.
