Hi, I am thinking about remapping my Focus ST. I was wondering if anyone had an tips or suggestions.
I know someone who mapped their ST and after around 6months had to replace the clutch. I dont want to be causing myself any problems in modifying it. If its going to ruin the standard clutch, I'd rather just save up more money and fit an uprated clutch at the same time as mapping it. Any help would be great! Thanks

well mine has been mapped/exhaust turbo back/filter 286bhp and in 5/6th with people in the back it will slip but when there is only 2 in car its fine so a cluch/diff will be next i think

Clutch slips in 5th and 6th. mine has a turbo back exhaust, remap and DSCi induction kit. Apparantly facelift clutches are not as good at dealing with the extra torque then the prefacelift due to a different clutchp. so spring time will be when i get my RS clutch fitted

i've had both of my st,s mapped mate, one with code:red and my current one with a "live" map which is done as the car is driving to better suit my driving style and the engine character of my car. both are excellent and i would heartedly recommended you get on and do it. as for the clutch, some get slip & some dont, think its just pot luck. but why fix what is'nt broken! get it mapped first & if you have any problems with the clutch ( which might not happen) then get it fixed.

Id just tune the car to what u wanted and when the clutch wears change it then.
But i ran about 8k on a standard clutch. Now iam getting a new clutch and maybe a new diff too, i wouldnt change it untill its broke but maybe you could do a deal if u got tunning & clutch done at the same time, then ur totaly sorted.
The question is how far do u want to tune your car??
I mean if your just going to map the car with no uprated exhausts etc etc carnt see the clutching at all untill very high miles, so why bother changing the clutch, but if ur going to go for the magic 300bhp then if u could get a deal from a company id get the clutch etc at the same time as its saving money.

i'm weighing up the choise to go either DS or mountune and so far i reckon its going to have to be the mountune. Too many people with clutch slip with DS and i know its a lottery but yes my luck is that bad

Well i have no clutch slip in any gear/revs/passengers with my 09 facelift after 15000 miles, so don't rule out DS you will be disappointed if you do


My stats are in my sig.

The issues are solely with either the clutch or the dual mass flywheel or elements of both.

And those issues are related not to bhp but to the amount of torque that has to be coped with. Some maps produce more torque than these components are designed to handle.

You then have to consider how quickly that torque develops. If the map allows for barely controlled boost pressure to be delivered very quickly then that will also effectively produce a very rapid build up of torque which will cause slip of standard drive train components.

If the mapping calls for a controlled delivery of boost and ensuing torque that is sympathetic to the drive train components you wont get slip and consequent damage.

Simple as that.

Regards, Don.

I'd agree with Don totally that it's torque behaviour which pushes the clutch/flywheel past it's limits - if you consider that a lot of people commonly experience the clutch/flywheel slip when flooring the car at say 3K rpm in top gear you're miles away from peak horsepower but right where the torque is climbing quickly or maxing out.

Don,

Can you explain why my car with DSCI map exhibits the exact same torque (381lbs ft/500+nm) curve as you describe above and i have had no slippage at all after 15000 miles.

Look forward to your reply.

Frankly, I cannot explain other than to say you have more luck than some.... mind you, you may be making your own luck by being a shade more mechanically sympathetic a driver than others....

How do you explain your good fortune vis a vis those who have posted quite different experiences?

Don.

Don't tempt fate!mine only started slipping at 16,000 miles
But as Don and others have said luck plays a part as some have slippage and some do not

Well i installed the DSCI map from new (on my 3rd ST now 06,08 and 09 with no clutch slip on any) and didn't run it in just gave it some beans from the off, living in Germany it has had VPower 100 octane fuel used (Tesco 99 when in UK) and has had plenty of use on the autobahns
and a few laps of the 'Ring so it has hasn't had an easy life.

I don't know why some people have slip and some don't but i am sure if it was torque spikes then i would definitely suffer from it.

Therefore i don't believe it is down to luck, i still believe it to be either weak clutches/DMF on some cars exacerbated by the cold/wet weather and not by the remaps (DS/CR/BF etc).

IMHO

Harmy,

As above post, i don't think i am tempting fate as i don't believe it is down to:

A. Luck

or

B. Driving styles or any of the remaps available

Plus i am chopping the
in for an
in April so if it does start to slip
it

some interesting points espeically from don and spiketheTyke, if i got the DS i'd run the dsci map (i think thats what its called) which is apparently smoother through out the rev range, which suits my driving style. Im almost desided on mountune but not totally ruled DS out given the power/pound ratio lol

Mine slipped when upped the power using Mod C map and other dreamscience goodies. Mine is an 07 plate ST and if you earch the forums alot more people report the clutch slip with 07 plate cars

Heard people mentioning dodgy batches of clutches but no idea if this is true
