Calling campagnolo experts
I have the campagnolo tool
I have the torque wrench
It's the last part on the frame
I even have a bruise on my face from where I wacked it with the wrench
However the last cup on my ultra torque bottom bracket just won't shift, I have given it loads of extra torque.
Going to the LBS for this project is cheating so that's not what I want to do.
Any ideas?

@Mike - bugger, forgotten about that "trick"
It goes against every instinct but, after soaking the thread, you might try tightening the cup a fraction (anti-clockwise) before attempting to loosen it once more. For reasons known only to the gods of spannerisation, this sometimes yields results.
The LBS is more than likely simply going to apply more torque than you have currently... going there is only to try and claim off their insurance if it goes wrong I guess?
My approach would be lots and lots of leverage and gentle application.
Scaffold pole would be my go-to for this.
it is looking likely for LBS, we do have a bicycle kitchen cooperative here in Reading and I might see if they have a vice but the project is to build a bike all from second hand parts and get it custom resprayed and as I now have all the bits I don't want to knacker the frame at this stage. I don't mind buying new BB cups if needed though.
watch this space...
when the only option is the application of a Birmingham spanner or excessive force it is time to get it to the LBS.
concur with the lbs option ... too much torque and you could damage the
frame
You may not want to take it to your LBS, but they should have the experience and tools to sort it out. I've had to accept defeat and do this for a stuck BB before.
Having said that, I recently managed to get a BB out with a 2 foot breaker bar and a lot of effort, but that was on a steel frame. And a bench with a vice would have been easier.
Dumb suggestion are okay here but yes everything removed! Have tried the hammer method. Don't have a bench vice so running out of options...
Dumb suggestion and stating the obvious but have you removed the spring clip that sits on the drive side of the bottom bracket ?
You don't need a torque wrench to take it off. Use a big open ended or adjustable spanner. Hit the end of the spanner gently with a hammer. That should budge it, unless someone's used loctite (why?)..
I am guessing here as i don't know what frame, alu cup into alu insert bonded into the carbon bb shell.
Proceed with caution, i am aware of frame inserts falling out, depends on which is stronger the corrosion or the glue.
It's drive side, English thread so clockwise removal, carbon frame, soaking in wd40 at moment
what's the frame made of, i am assuming this is a metal frame and threaded, you are trying to undo the cup the right way??? Could try using plusgas/etc to soak into the thread and try again after a few hours. If it really is seized, be prepared to risk the frame.
drive side or non drive side?
