RE: Mountuning a Fiesta ST

[Previous]

Id love one, But I'd have to de face lift it to the MK7.

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

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?

God knows. Really confusingly written article.

Also, I seem to have lost the battle against the word 'stock'. RIP the word 'standard'.

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.

But you'd still get all of the above with the top end power being permanently there instead of all this overboost for x seconds crap. To get 50mpg your not WOT, the emissions test isn't at WOT, and insurance is based on loads of factors not just top end power and whether that power is there for 15 seconds or permanently it still produces that power at some point so the insurance companies will take it into account.

I just don't see the point, if it resets every time you lift off the throttle, i.e. change gear, I doubt you would ever hit the 15 second cut off apart from on a top speed run, and how many people are actually going to do one of those.

So why have it there.

That Ford GT is more interesting....

Must be a worth while reason or Ford wouldn't have done it.

What difference does this make to the insurance? Anyone got a before and after comparison?

Those confused about the power increase this map gives, my understanding has always been that maps do more than just increase power and torque but also improve drivability.

I have a 225 mk1 TT and I'm wondering about a chip.

[Andy ap]

Dont flame me for saying this but 'overboost' sounds very much like a gimmick to me aimed at overtaking while preserving warranty. I dont doubt that this engine would be capable of a 15hp increase permantly let alone more.... Emeye if you want to chip the 1.8t id say do it there are no shortage of reputable mappers out there and the gains are decent, throttle response much better. Some maps bring out the torque but in the tt id say go for a map that allows more revs/free'er top end.

You do realise the 225 TT produces its 225 as overboost in a similar way? Afaik anyway!

[Steve vRS]

So the over boost lasts for 15 seconds and is available each time you puts the accelerator pedal. How many times do you give a car WOT in say third gear for longer than 15 seconds?

Or am I not doing it right.

[Andy ap]

If so then im talking crap but i though it used the k04 turbo and engine from the LCR. Cheers.

Google transient overboost. It's not new - the Lancia Delta Integrale had it. I have a recollection some Lotus Esprits did too. Ford used it in their last generation of diesel Mondeos.

It's a control mechanism, which if I understand correctly may help reduce heat build up and reduce turbo lag.

In the US they don't declare it, but I believe EU regs mean they do. Not quite sure why it's so controversial - the Fiesta ST seems to be the plaudits choice of hatch and the MP215 adds a bit more to the mix to make it better.

[AARONM3]

As a slight aside I see the US ST is also a 5-door which adds a dash of extra practicality.

Agree with both of above. You never will floor it for more than 15 seconds and it resets when you come off so for all intents and purposes it's permanent. I wonder if it's a clever way to lower insurance and/or tax bracket as it's classed as temporary?

Are mountune reputable now? I recall a few dissapointed yellow badge owners in the Fast Ford dyno shootouts.

I missed the Ford GT in the background! Nice.

Still want to see more of the GT40 MkIII if its real though, rather rarer than the GT (7 built).

Rolling roads are always giving out dubious numbers. I know someone who did 3 different rolling roads in a day and got a spread of 30bhp.

I've certainly seen people happy / unhappy with the numbers they've got from a huge range of tuners, over various different car models (not just Fords).

Hmmm.....might be fun but it still looks like a shoe. Eye of beholder and all that.

It's confusing to write about! The official line is that the power gains only come on overboost and the car is at the standard power and torque at anything but full throttle. In all honesty, it feels stronger all the time but you won't get any official confirmation of that.

And Ford says the overboost applies whenever full throttle is applied. However many times you lift off, it's back when you floor it again. Bizarre way of doing it IMO.
