replacing the ECU with a different spec one?

I have always wanted to know if this will work
some p11s are 110kw while mine one is only 96kw
would it work if i replace my ecu with an 110kw version?
is this gonna do any good/harm to the engine?

Well, you won't get 110kW (150bhp) by just changing the ECU, I'll tell you that!

I doubt the ECU will do any harm as such, but I doubt it'll gain you much, if any, power on its own.

You need to obtain the exhaust manifold and intake cam from a 110kW/150bhp Primera AND fit the ECU to get the full power levels.

Hey guys/gals im new to the forum, I have a Primera motor in a us spec car and was wondering at what does the Primera GT redline at. I was thinking about purchasing an ECU from a GT and seeing if it would help me in performance..?

Any help would be appreciated...

Probably end up being more work than it's worth. You'll have to make absolutely sure all the wires are in the correct place on the ECU harness. Not to mention I don't think it will make any difference.

Thanks, well today I will recieve my NX purge kit...:sun: Any secret mods for the Primera....
