I finally got round to taking my white 1M over to Southampton today to have DMS remap the car, after starting a thread about it a few months ago. I just wanted to say thank you to DMS who were very professional and did a great job. The numbers were astonishing..... Stock, the car was producing 346 Bhp on the rolling road. After the remap, 406.5 Bhp and a frankly astonishing 530 ft/lb torque. It now makes my Mk1 GT3 feel slow, and Monday will be interesting, as I am taking both to Silverstone ! Thanks to the guys who contributed to the previous thread. Great advice- I would recommend DMS to anyone. They have transformed my car. Mechanical alchemy!

It sounds fantastic! I think the 1M coupe is an epic car.
Are you able to take some footage when on track with it? Will be interested to see/hear it

Seriously, 530ft/lbs torque?! That's mental... What do they produce in standard tune?

I didn't see the pre-map torque figure and they are going to email me the graphs of the results next week, but DMS did say it was one of the strongest torque figures that they had seen on a 1M. BMW figures for a standard car are 335 bhp and 369 ft/lb. DMS told me most 1M's they have put on the rolling road have around 350Bhp standard, so BMW are being a bit pessimistic in their power claims. Interestingly, the technician I spoke to today was of the opinion that only 350 1M's came to the UK and not the 450 that we were originally promised, (like the plaque states in the car- 1 of 450 ) Not too sure about that, but they may have better information than I do ! I didn't believe the graph when I saw it, but it is a totally different car to drive since the map was put on. I can only relate to you what I saw today on a screen.......530 ft/lb.............

I have a feeling that the 1M will be highly valued in 20 years time as "the first proper turbo-charged M car".

Used prices have stabilised after plummeting for a few months and there are only 5 on AUC now available and 7 on Autotrader, there were 19 at one point.
Sorry for OT.
Am considering a remap myself but warranty etc always concerns me.

Do DMS offer you an iron-clad warranty on engine/transmission damage? I'd also hope that sellers will be honest enough to point out the remap & want them of potential warranty issues on the engine & transmission to potential sellers - but I doubt that will happen

What is the gearbox rated at in terms of maximum torque? Feels quite risky to me to uplift the output by that much without considering the other elements of the drivetrain.

S i have to agree, ive boosted up an ///M car and the amount of work i had to do to nail down the rest of the package and make it a genuinely reliable product was frankly insane.... Alot of work..... id love to see what the AITs look like (i know youve stated already) on a summers day with prolonged track use, the n54 was already known to throw alot of heat out, interms of AITs and oil temps.... Im sure its fine as i trust DMS, that must be a ball to drive!!! well done..... id defo look into water/meth injection, this can lead to proper winter day type AITs, and as you only spraying to cool charge its completely safe....

Please don't think I'm raining on your parade, but I'd be very surprised if the torque figures quoted are real. There have been numerous cases of 993, 996 and 997 GT2s and Turbos producing phenonenal torque figures on rolling roads. A certain Warrington based Porsche specialist fitted uprated turbos and a remap to a 993 GT2 some years ago. It allegedly produced circa 600+ft lbs of torque on the rollers. No one familiar with Porsche engine tuning believed the figure and many toys were thrown out of prams in the subsequent discussions on the topic. Check TB993Ts numerous threads on Rennlist for his indepth views on the subject. Many think the software used on these rolling roads cannot accurately process the torque figures produced by a turbo engine.
The torque figures you mention equal those of a 997 Turbo on temporary overboost (and as the previous owner of 996 GT2 that was mapped and fitted with an uprated Ruf exhaust, believe me I do know what 550hp and similar amounts of torque feel like ! !)
I've recently purchased a VO 1M coupe, I have to admit I've been taken aback by its overtaking prowess ! As the owner of a Manthey K400 converted Mk1 GT3 too, I think the 1M is probably the better overtaking tool ! !
As I said at the beginning of my post, please don't think I'm trying to rain on your parade, I suspect your hp figures are pretty realistic as the cars do seem to produce more than the factory specified figures in standard form. However the torque figures mentioned seem "unlikely".
If they are realistic I suspect that if you use the car to its full potential you'll be having clutch and transmission issues in fairly short order. In the event of any issues, should DMS abandon you (and I'm not suggesting for one moment they will) you'll not find BMW sympathetic to any claims.
They know what they've produced in the 1M, they'll have reined in the horsepower and torque figures to ensure longevity of all the transmission components, and any "failures" will be treated with suspicion. In the event of a gearbox/clutch failure (or worse still engine failure) they won't think twice about sending the cars ECU back to Germany for interrogation.

lb/ft or N/m I wonder?
The stock engine makes 335bhp@5800rpm and 332lb/ft@1500rpm, and 335/5800x5252=303lb/ft at 5800rpm also.
Say the 406bhp is produced at the same 5800rpm, that would be 406/5800x5252= 367lb/ft@5800rpm which is +64lb/ft over stock. But it is more likely the peak power was made higher, say 6000rpm, so 406/6000x5252= 355lb/ft or + 52lb/ft over stock. Either way somewhere between 50-60+ lb/ft.
Now if we talk Nm; 530Nm x 0.72= 381 lb/ft or + 46lb/ft over stock.
Probably Nm IMO, but a good result all the same.

Thanks for all the replies to the thread. Regarding the torque figure I was given for my remap- I must admit to being very sceptical about it myself. I saw the screen and it said 530 ft/lb on the graph. It was a rolling road, etc and I have no idea how accurate these things are. I have nothing to check it against, apart from the feeling from the driving seat. Having had a day and a half driving it now, and the car is much quicker after the remap. The software is excellent as it's as tractable as before, but throws you down the road if you are in the mood. I scared myself a bit in it yesterday, if I'm honest ! DMS did a fantastic job. They have a selection of maps, and pair their most appropriate one with your particular car. They are true car enthusiasts too. These guys love what they do, and they are obviously very good at it. Regarding transmission and warranty issues............ I accept that these both may come back to haunt me at some point. I knew that when I took the car over there. If I break something, it can be fixed - It'll just cost me. Silverstone tomorrow.........my first trackday in the 1M -and my GT3 is going for comparison !

Impressive figures. I'm so tempted to get mine done. My main concern is the standard car struggles to put its power down in 1st and 2nd gears. What must it be like with all that extra power/torque?
A good point has been raised about early clutch/gearbox problems. Are tuners able to keep standard power in 1st and 2nd and then give the full monty from 3rd upwards? It works for cars like the Focus RS (fwd I know).

Although the 'same' gearbox surely the diesel will be geared longer?
Correct me if I'm wrong, but if we're talking at the flywheel figures then a diesel with 500lb/ft will put less torque onto the road, via the gearbox, than a petrol with 500lb/ft beacuse the diesel will be longer geared due to lower rev range?

At what point in the rev range is peak power? (The 1M doesn't have a problem with headline figures..... it's problem is that peak power happens 1500rpm shy of the red line. If they have fixed this i want one, otherwise not for me) edit; just saw it's still at 5800  meh
