Took the plunge having now owned my Focus ST for two years and bought a Dreamscience unit that loads tunes via the ODU.

I have only loaded the DSCI map so far, best all rounder I'm lead to believe. Pretty rapid, the 'supposed' power is 270BHP and 330lbft. To put the latter torque figures in perspective:

E46 330ci = 221lbft
E46 M3 = 269lbft
E90 M3 = 295lbft

So you can imagine how quick it feels.

Other tunes:
Performance - 255 bhp 285 lbft
Performance Plus - 260 bhp 295 lbft
Race - 265 bhp 310 lbft
Race Plus - 270 bhp 330 lbft
DSCI - 270 bhp 330 lbft (different power deliver of above)

Torque steer does not seem to be an issue even in the wet for the quick dabble I had tonight, but I'm probably going to stick on the Performance Plus map as I'm concerned it hits 1.2 bar and sticks to 1.1 bar to the rev limit.

Other mods the chip does:
1) Torque control module adjusted to deliver instant pick up during acceleration
2) Torque control module still in place for 1st gear to protect the drive train.
3) Red shift light to indicate best gear change point activated at 5900 Rpm
4) Rpm limits increased to 7500rpm for highly modified cars which can take it.
5) Limp home mode still in place but threshold advanced to allow more continued performance.
6) All tunes clear flash counter and dash codes after programming a tune or flashing back to stock.
7) All speed limits removed.

That is all :D
 
Nice ;) A focus ST overtook me on a dead straight country road the other day and I was stunned how quick it accelerated from 60mph
 
Well not going to bother getting mine RR'ed so will never know, but these are the claimed numbers. Certainly feels very quick. Boost comes in at 2k and just does not drop off! But I was shifting at 5.5k :)

Will see what effect it has on the twisties at the weekend. I only tested on a wide A road, as I did not fancy going off road on my first try being wet outside :p
 
Not very fair comparing it to other faster cars torque.

Torque feels fast, power to weight ratio and gearing win races ;)
 
Because you would need over 300bhp to make it worth its while. Add to that the cost R&R then it does not remain affordable to the masses. Shame the RS did not adopt it mind, but hey I would like to hope Ford engineers know more than me. :)
 
peak torque figures dont tell you an awfull lot

where in the rev range is the torque increase, and is it at the expense of the torque elsewhere ?

To really understand how the remap effects the car, you need a dyno plot to see what its really done. In my cars case it added a load of torque low down which was great for pulling away from roundabouts in high gear, but not a lot of use on a hard dash down the 1/4 mile strip since its never below about 4000rpm.
 
If you're going to pick a number of out and out performance, BHP is the best number to go by. From a practical day-to-day perspective, an engine can produce 300 lb-ft and accelerate a car no faster than one with 200 lb-ft, but an engine with 300 HP will always accelerate the car faster than one with 200 HP.

Either way I bet 270 HP and 330 lb-ft makes the ST quite fun to drive, especially when rolling!
 
My friend's Focus ST also has dreamscience along with a couple of other mods (dsci induction kit and intercooler of some sort, think a janspeed catback too), but my it pulls very well, absolutely effortless pulling power in all gears...fuel economy isn't pleasant mind!
 
Uh oh, I started this didn't I, sorry lol.

All I know is...

Golf TDi 170 odd bhp 317 lb/ft torque

Vs

Integra Type R 190 bhp 135 lb/ft torque

=

Integra faster, like I said its all about power to weight ratio and gearing.
