Mountune launches m400X map for Focus RS

Tuner boosts Ford's all-wheel drive super hatch with enhanced 400hp map and adjustable engine modes

---

Mountune has created its most aggressive map for the Ford Focus RS yet, extracting 400hp and 413lb ft from the 2.3-litre motor as well as making it more responsive throughout the rev range than before. The new m400X map can work with the car's standard turbocharger - although Mountune does recommend an upgrade in order to further performance - and improves on the old m400 map with more accessible peak outputs.

On the graph, that's illustrated with power and torque curves that stay higher for longer, providing the four-cylinder motor with more mid range punch than before. The m400X is the top of two new settings, with new m400R software providing slightly less aggressive mid-range performance but identical peaks. Both maps come with the same selection of hardware as the m400, including a freer breathing intake and exhaust system with a sports cat.

Other changes to the 400 software allow owners to return their RS to the OEM map or switch to power-reducing fuel save and valet maps. The engine can also be switched into a mode optimised for dyno runs or even set to an anti-theft setting. Plugging an mTune handset into the car's port also grants access to rev limit, launch control and full throttle shift functions, if you're the sort who prefers to keep your right foot pinned into the carpet.

Mountune's 400 maps don't come with a Ford warranty like its less aggressive ones, obviously, but the company does provide a parts warranty on all that new kit. Prices for the upgrades start at £595, but those who already have an m400 map can upgrade for free, while those with an mTune handset can get their cars upgraded for a reduced fee. So, Focus RS owners: are you tempted?

Are these able to handle this sort of power reliably now?

well for the first few yards

The 400hp map should be the minimum for the UK's congested roads. And for start/stop commuting a larger turbo/ intercooler and injectors giving most likely around 500hp is an absolute must...as will be a shovel and brush to clear up the drive train after detonation..

They have been for a while to be honest - although I've still got over 2yrs of warranty so I'll sit on the approved FPM375 kit for now

Yeah, losing your warranty for the sake of 25bhp would be insane. Bet it's pretty awesome with 400bhp, mind.

Ours is out of warranty at the end of the year and for the 1st time in years I’m not keen to move on to something else after 3 years ownership. It has the FPM375 pack and Mountune back box installed so eyeing up the M400 upgrade to keep me happy for a few more years.

Sounds basically like a Revo SPS box.... wouldn't surprise me if it was the same sort of technology.

Happy days !

Brilliant!

Running the Mountune MR420 map on my Mk2. Just saying

Through the front wheels

413lb ft is an impressive number. That's got to effect OE durability surely?

Sound like a good upgrade once your car is out of warranty.

Mountune use COBB

Identical to "Mountune's"

Would be interested to hear what other hardware is recommended with the map.

I'd guess induction kit, maybe intercooler and exhaust?

All on their site,-

Required m400X Hardware

mTune handset
High-flow induction kit
Sound Suppression Chamber (SSC)
Uprated turbo re-circ valve
High-flow hard pipe
High-performance alloy intercooler
3" downpipe with 200-cell sports catalyst
3" V3 cat-back exhaust
Forged pistons
Steel conrods
Uprated (1 step colder) spark plugs

[Onehp]

Sounds costly.

With similar mods but without opening the engine, the smaller 2.0 VAG ea888 g.3 will push for 500bhp...

But there is more to driving than Power (unless you live at the Autobahn or have to win at Santa Pod), and as such if I had an FRS I would setttle for the 375 kit...

Just for 400!! That motor is horrendous.

Pushing a rod out of the block for 500hp you mean

All form of tuning and increasing of output will decrease the durability, even the mountune stuff.

That is what is recommended by Mountune apparently. Plenty of cars running over 400bhp on standard internals but Mountune don't advise it.
