These day's you'll be lucky not to go into limp home mode.

You'll also need your own starter switch, and possibly some way of fooling the body computer into ACC.

Nothing on my Renault can be done manually, while I can do an engine off roll start, I then can't start the engine with the starter button until I come to a stop.

I think bump starts are going to be bad for the DMF, too.

You'll probably also find that if you add a kill switch, Stop/ Start will keep cranking the engine so you'll have to find a way around that.

Lots of PITA issues in your future, I see.

My Renault returns under 7l/100km city, which is pretty fine for a 2 ton van. I don't see mods as really being worth the effort. P&G doesn't work as there's too much fuel during the P and even EOC wouldn't be enough to make up the difference.
