Re-Mapping, your experiences.

I think its bullst to be honest. "Torque map" If its a good map it would create good torque AND power. Good power is made by maintaining that torque up the revs, god knows why you would intentionally not maintain that power and call it a "Torque map".

I would guess they actually got a more aggressive, peakier map. A lot of tuners offer a map with a flatter torque curve and only slightly reduced power levels, but the standard clutch gives up at 300lb/ft.
This map sounds like it has more torque over a narrower power band, so big numbers, but not as progressive.

(All IMO etc. not a mapping expert or anything, just interested PH'er!)

Eh? Why would having a higher peak torque give you a narrower powerband?

But the focus can rev higher...........

makes sense, although my 330d running 270bhp against my mates stage 1 focus rs running 340bhp are virtually even in performance, and we've tried a few times! he literally gains a car length on me from 60-140mph (tested on an autobahn)

I've a Bluefin remap on my 1.8 Mondeo. Probably no more power, but it certainly made a huge difference in drivability. Lots of low end torque, gone is the huge hole in the power curve at 2500rpm, and it'll rev hard right up to the limiter. Best £300 I ever spent.

After a year or so, I decided to go back to the factory map for fun, to see how bad it was. Felt like I was driving around with the handbrake on. Map went back on pretty quickly.

Any bad points of doing this?

Why don't manufacturers do this in the first place?

Does anyone really declare this on the insurance?

Not sure I understand how it works, surely the same engine tweaked to be quicker would use more fuel?

Would you have to let say Ford know it's been done before a service? (so they don't change/fk it up)

Mondeo ST TDCi, how many horses would I be expecting to gain?

Sorry for throwing them questions at you lot

Lots of reasons manufacturers don't do this, emissions etc.
Yes, sensible people do declare it to their insurers.
A remapped engine is theoretically under lighter load therefore uses less fuel UNLESS you are using the extra power available of course!
No, you wouldn't need to inform Ford, they should have no reason to mess with the ECU & they should be unable to tell.
Your TDCi should see some pretty impressive gains, look around & see for yourself.

I remapped my Smart roadster, gave her a bit more oomph and speeded up the gearchange.
An added bonus was the place doing the remaps was also a Pagani dealer, so blagged a nose around and sit in a Zonda.

My Focus ST is remaped using Dreamscience. I have 5 different maps to pick from. Currently using DSci map. Bought it when it was on sale back in January. Should have got it earlier as the car feels soooooo much better. In standard form, it feels like its holding back but not now.

Bluefin say a 30bhp & 32ft.lb gain

Increased stress/wear on drivetrain

Emission regulations

Sometimes.. Often a leaner mixture can produce more power.

No, wont really make any difference to servicing with just a remap.



Assuming yours is the 155Ps version, Superchips (as an example) claim an extra 30bhp and 32lb/ft.

[FellowPazzini]

Thanks. Oooh £400 seems allot to pay for an extra 30bhp but I'll probably (eventually) still go for it although mine has done 70k miles already (should have had it done years ago).

Is the emissions a problem to the extend of the car could possibly fail an MOT?

This.

This is the one thing that puts me off mapping modern turbo cars.

I bought my Alfa JTD remapped, not long after i bought it the clutch was slipping in the high gears.

I think modern turbo diesels are 'pushed' as it is anyway.

Plus it drove much better standard, not 'on/off'

That doesn't sound good. I got a few quotes the other day for a new clutch etc and they was all coming in around the £7-800 mark for the Mondeo. It's never had one so at a guess this might edge the clutch towards breakdown.

Did my 944 S2 last weekend, I cant detect any difference !

Also factor in a DMF to that price.

Its the huge torque spikes the maps create that kill them, in the higher gears when coming on boost around 1800rpm thats when it would slip, under WOT of course.

You could always get an uprated clutch, but then id start to worry about how hard the fuel pump, injectors and turbo are working.

But thats just me.

Had my monaro remapped and it transformed it, but it was understressed to start with and the drivetrain was built like a tank.

I don't want to start another 67 page power/torque thread or a petrol diesel one but if you mate really has 70 hp on your car and the significantly lower weight the focus should batter the BMW in straight line. Something must be up somewhere

[A.J.M]

Have my freeby td4 remapped. Has the BMW M47 engine and has been remapped for 27k now.

Much better throttle response, better mpg and stronger torque curve.

No issues with clutch or transmission from it, does smoke a bit when coming on boost when i have the foot flat, but no smoke no poke.
Did kill 2 hoses off which was interesting for the audi behind me when one let go at 0.9 leptopns.. One second i could see him, the next there was a massive cloud of black smoke.
Silicone ones fitted now so no issues, i change the oil and filter every 6k anyway to keep the turbo healthy.

[thiscocks]

there seems to be a lot of misleading torque on this issue

[S6PNJ]

I've been considering a re-map for our workhorse as it's a bit slow but then it wasn't bought for its speed! Its Citroen C5 Estate, 1997cc 90 BHP HDI. It is going to be worthwhile just buying a cheap plug in chip or getting one of the local chaps to visit etc? 130 Euro from racechip.de

Same.
