I've had this fitted on mine for around 3 months and it's worth every penny.

The easiest way to describe it, is it's like being in the gear below. Sat in 6th at 70mph at 2500rpm and put your foot down and it pulls away like your in 5th at 3700rpm. The drivability is also excellent, it will cruise around town better than the standard car and the power is immediate, zero lag at all.

You could go to someone like Revo and get an extra 10bhp for £100 less but I can thrash the hell out of it all day everyday and not worry because I know that it's been properly tested and developed. If anything goes wrong I simply take it back to the dealer.

I'm getting the Billet Short Shifter fitted next week which should add even more to the experience

I'd love to try one of these Mountuned versions. I currently have a Fiesta Zetec S and the chassis is brilliant for handling but it doesn't have the power. I think I'd prefer the Focus ST as a daily though, even though the 0-60 figures are quite similar and this is cheaper.

I approve of the collective for Daves too.

I notice there is an intercooler upgrade too...

Im a little confused. So when you floor it the standard 180 becomes 200 but the mountune only gets it to 215 only when on full throttle again?

So a Remap and panel filter on the 1.8T gives you 215-(220 max)and about 230lbft all the time consequently raising the power/torque curve permanently (I know engine size is different)
That sounds a bit st to me considering (if i read it correctly) thats a 15hp increase for 15 seconds at a time for £619!! whereas a 1.8t remap will give you about +35hp +50lbft for half the dosh, and its permantly in use to boot and as far as i know doesnt show up on dealer diagnostics. (Allbiet without a warranty mind).

Please correct me if i've misunderstood.

ETA: the money savings could then let you buy a cat back exhaust etc etc

Ford should do this upgrade as standard fitment and stop charging people for it.

It's fairly straight forward once you get your head around it.

You get full power (200bhp standard) for a max of 15 seconds at WOT. As soon as you lift your foot up it resets so as soon as you put it back down again, you get the full 200bhp once more. Who goes flat out for more than 15 seconds at a time anyway?!

It also varies depending on temperature as well, if the engine temperature increases to a high level it will restrict the power to prevent further damage. This would only happen if you were on track at 30+ degrees for a long period.

It all means you get higher mpg, reduced CO2 and lower insurance. That means it'll do 50+mpg on a run, it's £125 to tax and I pay £600/year for insurance despite being 20.

Win win all round IMO.

Hard to argue with that.

[Andy ap]

I can see the benefits where tax (loosely considering a car is taxed on an as new basis not including mods), insurance and overall emissions are concerned but as this by the sounds of it is purely raising the overboost threshold that would make no difference to the mpg when driven normally. And thats a lot of money for very little gain. I dont think there are many 1.8t remap owners out there that are loosing sleep over peace of mind issues. I suppose its a feasible way to have a car modified when new and still keep the waranty. After warranty i would deem that a rip off.

I don't see the relevance to the 1.8T which is getting on for what? 15 years old? The remap doesn't just up the boost pressure on over boost and that's it, throughout the rev range it feels so much more responsive and eager, there's no hesitation or lag at all. Even when on part throttle (when overboost isn't activated) you can feel the difference.

I agree that out of warranty, I'd go for something else. However on a car worth £17k, I don't want to risk it.

Must get my eyes tested - I thought the title was 'Mounting a Fiesta ST'.

I thought this would be a thread on the best positions - missionary, reverse cowgirl etc...

There's always one who has to ruin it for everyone else!...

Its not only you that noticed that! Now I have horrible images of the Mountune tuning staff lifting up a standard ST's bonnet and then proceeding to tune your pride and joy via the medium of carnal knowledge! For those who've been mountuned - better check your suspension!

[Fastdruid]

Forget the Fiesta (not actually that I'd mind a go, sounds great fun), more pics of the MkIII GT40 please.

These charts are a bit rough and ready and, I doubt, 100% accurate, but when plotted against the full Tufte-compliant axis you get a better picture of the increase.

[Andy ap]

I agree on the throttle response point that will make a bigger difference than the actual numbers IMO. As for the venerable 1.8t comparison the point i was making is you could get more gains from something at least ten years ago. I dunno i expected it to of come a lot further in that time really.

That's true, look at the MK1 Focus RS, you can get a 50bhp increase with just a remap!

The problem with these small, modern turbo engines is they're designed to be much more efficient than 10 years ago due to emissions and fuel costs. Add to that the use of small turbochargers to reduce lag and the gains aren't as high as they used to be.

We had small turbos 10-15 years ago, Heres the K03 (bottom one) and K03S (top one) i believe if google images is correct fitted to the staple of 1.8t's (sorry).



No idea what size is on the Ecoboost engine (is that right?) But yeah emissions and efficiency is definitely much more of a killer now. Despite the fact that when putting that aside will get you quite impressive results for the size of engine now. 25 years ago you'd of been locked up for saying you could get +220hp from a 1.6 and it will do it all day long.

Turbo's may be more limited now - they are tuned somewhat more tightly than before. I think a lot of that may be to do with the matching that the suppliers carry out now compared to before. I can't comment on what has happened previously but the requirements for modern turbocharged motors are somewhat trickier to achieve than they were 10+ years ago. Low end torque requirements mainly. Far more aggressive than they were before!

Injectors will be the biggest thing limiting performance increases in coming years. DI injectors ain't cheap. Also, smaller injectors = better emissions for legislation. Specifically particulates. Just needs higher fuel pressure than today for top line performance.

Looks like a handful of the aftermarket companies producing ECU solutions for DI cars have resorted to offering new manifolds with a PFI fuel system attached which supplements fuel at full load? Not as effective as DI and vastly inefficient by comparison but probably still cheaper than the alternative.

Thats what I was thinking, is the remap on all the time, and you get the full 215Bhp, or does the map only come on when at full throttle?
