R56 - Remapping a Cooper S - Jungerns

What sort of cost is involved and basically is it worth it ?? I'm all for fun and appreciate it would likely be even quicker but does it decimate fuel consumption ??

Thanks...

I wouldn’t. The PSA VTi motors in the R56 are weak and prone to timing chain failure among other issues including gearbox problems. The Cooper S is under enough stress as it is and is plenty quick enough to be all the fun you need on the road. Add more power beyond the manufacturers original specs and it’ll almost certainly bite you.

Instead of spending money on a remap make sure it’s serviced by a genuine Mini specialist and give it a diet of good premium fuel. It’ll go a bit better and it’ll give better service.

Yes fair enough it is extremely quick as it is compared to every other car Ive ever owned. I didnt quite realise just HOW quick it was. I'd driven a standard Cooper before and thought the S would obviously be a bit quicker but thats an understatement to say the least

Had a similar discussion with a friend recently who was asking about remapping his BMW 330d to match the 335d. I said that manufacturers spend millions to design these engines and why if it was as simple as just turning up the wick did BMW go to the bother of fitting two turbos and a host of other upgrades to the 335? Again his 330 is genuinely quick and will exceed 140mph with ease, so why the need to add more power?

Why do firms make bigger engines at all if you can simply remap the smaller motor? Range Rover 6cyl diesel v V8 diesel for example. Just update the smaller engine and save a few million surely? It’s not that simple, it’s about longterm durability and all round drivability. A remap will damage the engine, put added stress on a gearbox that wasn’t designed to take it and often costs drivability by altering the power curve. More power at the top but possibly it’s less tractable elsewhere.

I found this out to my cost when 'tweaking' two stroke motorcycles in my teens. They never lasted long.
