My Cooper SD is booked in tomorrow with Performance Torque tuning specialists for an ECU Remap!!! :D

I thought I would share the outcome of the £395 I will have spent on having this done as I struggled to find any feedback from people to see if it is really worth it. I have been told to expect around 35hp and 60-70nm torque increase so in theory this should be money well spent.

Will keep you posted!!

24 hours on.......... VERY HAPPY!!!!!

The difference the remap has made to the cars performance is amazing it now drives like I would have expected a cooper SD to drive!!

The torque increase is amazing and on an eco note I managed to get 8 mpg more than what I normally get on my daily motorway commute.

The car was running at 143bhp on the dyno results prior to remap and over 180bhp after.

A must have cooper SD modification!!!

I assume this is a one-off re-map. If the ECU were to be subsequently re-flashed by BME then the map would be lost.

I used to have an uploadable Evolve map on my Dooper, accessed via the OBD. That was useful as I could change the map back to standard when the car went in for a service.

But 180/370 are impressive figures and even were that to be at no loss in mpg it would be so very very tempting. Perhaps an idea for Spring when the weather willb e getting better as opposed to now, with dark nights, wet roads, leaves and icy conditions later to look forward to.

Yes it is a one off remap but the company I use said if it was to be removed they would load it back on free of charge. They have assured me that the remap is invisible to BMW so hopefully this is the case :s

As you say maybe a modification to consider in the spring now as it can struggle to put the power down if the roads are wet as it has so much more power.

jits go 202 brake horse power and around 300nm torque 1st and 2nd not much difference evry think aboth is ridiculous shes now 2 much:D
Mmm figures sound wrong to me as well, as yet mine is unmapped and has 143hp and 305Nm, so with a map I would expect around 175-180 and 370Nm.
A DPF delete adds about another 10hp.
But I certainly would not be happy if my car went for a map and came back with less torque.

Was the car checked on a Dyno? Curious to know what the starting BHP was.

also, an idea of the price would be good.


I thought a 118d and a 120d had different bits bolted to them, injectors, possibly turbo etc ?

Hi I had my paceman SD remapped by Celtic tuning it was stock and now they say stage 1 it’s 199bhp.I do not know actual figures but my car now goes like a rocket,loads of power in every gear,it pulls like a train.I did this a year ago and everything is still fine tyres are very good and engine is superb it cost me £250 best money spent,I would do this to every next car I buy no issues at all and still over 50 mpg

The main thing you have to watch out for is the clutch, how long will it last now youve upped the power?
Not a MINI, but on another car upping to power from 160BHP to over 200BHP by remapping halved the life of the clutch, just a 40 to 50BHP increase had it failing as early as 20,000 miles when it should easily do over 60,000 to 80,000 as standard.
And with all the problems that come with the dual mass flywheel types especially they are expensive to replace, well over a grand in most cases.

Just to clarify because, I FacePalmed when I read that someone thought the X18D engine like the BMW 1 Series has, the 118D (Which is the Countryman SD's engine) was a 1.8 Litre Diesel engine. This is Incorrect.

The X18D and X20D engines are both the same engine, but as some pointed out they do have very slightly uprated components and more powerful thanks to different ECU's. Just thought I would put my say out. Big mouth syndrome.

Does any one know what the deal with warranty is when getting a remap and if after servicing it can be detected or removed? Wouldn't want to pay £400 for something that could be removed....

Cooper clubman s diesel remap

Hi All
My wife is taking ownership of cooper s clubman diesel tomorrow,I was hoping it could be. Remapped? I have contacted celtic tuning and they say her car is in the change over year and the ecu could be locked.Does this mean it could never be remapped/chipped.
Disappointed maxi boy

I have just had my Cooper SD (63 plate R56) remapped by Performance Torque,

My car started with 153 BHP so it was a strong stock engine and PT managed to remap it to 197.7Bhp so a nice increase of 44 BHP. Then the torque was running at 254.8 with a remap to 312.5!

Definetly worth every penny! so much more responsive and just keeps pulling especially in 2nd/3rd

Repost to other thread :)

Well, Had my remap done today at southwestincartech. The guy I saw Mark is an agent for celtictuning who supplied the map. The figures they quote with this map are as follows

Power from 167bhp to 238bhp
Torque from 265lb/ft to 326lb/ft


All this on standard equipment. All i have done to the engine is a K&N panel filter.

The ECU had to be removed from the car, opened up & a bit of soldering done (F series can't be flashed through the OBD)

My verdict? Best £290 i've ever shelled out. THIS THING ****ING SHIFTS!! To say that i'm a happy bunny would be an understatement. Only drove it home so far (a few miles) but jesus! DSC was flashing like a christmas tree light! Cant wait to get out in it tomorrow on my way to the hospital :thumbup: I can fully endorse Celtic (who do a mobile service btw) and also Mark at SouthWest In Car Tech. No dyno run to show i'm afraid as the engine (2,000m) needs a few miles on it yet to show a true figure. I have an open invite to go and do a run when the car has reached the required mileage :)

I think I know my car better than you.No offence,but the map I had done had come from a paceman that had been on a dyno.My map is suited to my car and is as perfect as it can be for me.As I said,the torque is massive through every gear and you only get more torque by pressing the loud pedal,but you don’t have to floor it every gear,that is the point.If I did that,it would literally take off.I still get over 50 mpg and there is precisely no more wear on anything,not the engine or gearbox,these were built with the top tuned engines in mind,same as the clutch.Time has proved this already.On another note,the ONLY reason that timing chain tensioners fail is because the oil and filters are not changed early enough.I change my oil and filter every 3000 miles.BMW recommended every 20,000 miles.That may be ok if BMW oil is used,but if any other make is put in,it wont be good enough for that period of time.It is obvious to those that know,like anything,if you dont look after it then you Cannot be surprised if it goes wrong

no your right of course you would you drive a mass produced car,, and someone who has spent their life repairing and mapping cars would have no clue of course your right silly me.

maybe if you read what wrote,, ie its a known weakness with all n47 diesel engines timing chains its not a made up thing whether mapped or not makes not much difference only thing that does is how hard and long rev'd hard,, by a bhp map pushing the power to top end do wear them faster if driven like it, fact torque is where a diesel should set,,
other facts all no rolling road live maps are made from a one off rolling road on a similar engine ,, trouble with generic maps they are just that all fuelling were recovered and timing and air intake even temps and air pressure etc on one day on one car that might of done 50.000 miles or 5000 miles something you would not be sure of,, so a map relies on all 02 sensors being the same and mas air flow being the same and air temps being the same as your car on that day to get best results,,, hence why my pint you totally missed was live map rolling road time is always best kind of map to have as its for that one car with any of its differences in fuel and air and timing etc,, as for mapping hurting a engine no its the stupidity of some drivers who dont know what they are doing with a mapped car,, ie all increased heat and every revs more revs more wear not me just making that up its basic understanding,, below links worth reading maybe you will understand a little better,,, not a if its a when they all do, nice to be in front of something before it happens ,, was not picking your car or your post apart, but maybe everyone else who have suffered the n47 and its £4k gift when the chain slips might feel its nice thing that someone gave them the heads up before and they replaced the chain before it went and destroyed the engine,, thats all have to say now goodluck

i'm totally up for remaps i got a cooper s at moment just done goes like hell, i also know that the longer i rev the thing at top end where all the fun is it will at some point let go, hence why mapped to mid range on a rolling road for best results is better than generic map ie one mapped used on thousands of cars as a mid range one map fits all,,

If the car is standard with no major upgrade mods then a canned tune will have no problems as they'll have tested the tune many times on base cars on a dyno.

Companies like Superchips, Celtic tuning etc... are good at what they do and for the price.

Dyno tuning is best if major upgrade mods for bespoke system.

trouble is generic maps were produced on a day with one car how worn was that car what was the ambient temps and air pressure, also all the wear on sensors or dirty sensor injectors fuel used etc etc, also as it a fit all cars map that map would be trimmed with more tolerance to other cars being though miles maybe,, its until you drive a generic map car and rolling road set car that you honestly feel the difference and all maps are not equal

Go for it,unless you are going to race it,then a remap will help the engine to breath and operate how it was designed to do.My paceman was 143 hp from factory,but other BMW tunes have them at higher or lower states of hp.You can remap to a higher bhp up to 200bhp without any issues,it will not make the clutch fail or the brakes fade or any of that old fake info.Stage 1 is safe with no extra hardware required.Forget all the naff about timing chains breaking,this has no bearing on it at all,oil changes are the thing,or not changing the oil to be precise.I have done it on 3 vehicles now no issues at all,andbif there was to be it would have happened anyway,not because of a remap

I'm still fairly keen on getting my late 2012 R56 SD done, we had a REVO remap on a MK4 Ibiza for 13 years and it never missed a beat. 150k miles and sold it with the original clutch at 16 years old.

Insurance? Yes, you should notify them. Our insurers were pretty chilled about it, but at least we told them.
