Had the CSL remapped

[anissut]

So, I had my CSL remapped a few weeks back. I haven't modified a car since I was 20 years old and I'm one of these people who has never seen value in it. Also, the CSL is a bloody good car out of the box. So when it was discussed that my car be developed/tested for a remap, I went into it with no expectations and a fair bit of scepticism

Firstly my car dynoed standard at 369.8bhp which I was surprised by. Apparently at the same time a std E46 M3 dynoed at 338bhp so clearly my car is a good one. I was really happy with that as I always felt it was pretty strong. On the flip side maybe the remap would be pretty useless then as the car was already producing really good power? Then, a couple of days later under different conditions the car dynoed at 362bhp.

So as the week went along I was getting more and more intrigued as I was kept up to date with all the things being looked at. Most of it made no sense to me as I'm not a particularly technical person but I did my best to understand what was being explained to me.

So, the car turns up yesterday. I have driven it 60 miles in varying conditions but in mostly crap weather. Here is what I have noticed:

1) The car is faster. It's not "WOW this is much faster" but it is quicker for sure.

2) The changes are very discrete. You would have to know the car to know the changes.

3) Power is definitely more linear. It builds consistently through the rev range all the way to red line.

4) I always felt the CSL had some flat spots, maybe a better description would be, sometimes I'm thinking, come on get on with it low down the rev range as I knew above 4500rpm onwards was where the action was. Now, it feels like a solid, gradual build up of power with a crescendo as you get towards the red line.

5) Really liking the sport button memory. With sport button on, the car feels less razor sharp but not as jerky as before.

6) I think the car has more of a bark about it whether it be partial load or full load.

7) Under partial load the car feels sweeter to drive. More enjoyable to rev and more push in the back. Could just be me wanting to believe that but that's what I have sensed so far.

8) The CSL as std felt a little flat at times before the power came in higher up the rev range, that doesn't seem to be the case anymore, it feels more progressive.

I haven't had a chance to drive the car much due to weather conditions but as I do I will post anything more I notice with the car. I don't even know/care what the actual power output is now but it certainly feels different in a positive way. Weather is a bit crap at the moment and its hard to really test it 100% as I live in London and lots of cops and traffic around so only getting a few opportunities to really open it up.

Has anyone else remapped the CSL and what have their experiences been?

Seems like a good map Anis

SIMTIS did mine a couple of years ago and it was better but propbably used higher revs which can shorten life of motor

Simpsosn have an ESS map on mine at the moment but tbh not sure if i can tell any longer if better or not. Dyno numbers on mine nothing special, last time i think it was back at 355 bhp although i know this time last year it was 368bhp

Stick up you dyno charts Anis, I might pop over to Sal at Evolve who i believe did yours when and if i get the cams done

[DazBlackCSL]

The thornmeister did mine ( http://www.thorneymotorsport.co.uk/tuning/E46_M3_Power.shtml ) .. S2 with SS Cats and race BB... not sure the BHP as was never dyno'd but runs like a dream since it was done last year, and seems to pull a little better than the others (Rob's) and the few around me.

Not enough to get more than half a cars length, but smoother I would say overall.

Depends what your trying to achieve I suppose TBH Brakes / Tyres / Suspension in that order will make the most difference with driver ability / training included ;)

To give you an example :
Std RS Focus (engine wise ) running on KW clubsports with half cage and brake upgrade ...

http://www.raeder-motorsport.de/html/raeder_ford_focus_rs.html

I have seen this car in the flesh and it really is running std engine :smokin: Check the lap time and vid and the lovely half cage :whistle: :smt047

Daz, that's turbo car with remap

-Leistungssteigerung +40 PS +80 NM 899,00

My personal approach is to stay away from a remap in the CSL (when it's stock like mine).

That is the options... the car I saw and spoke to them about.. the one in the link is running std ;)

My personal approach is to stay away from a remap in the CSL (when it's stock like mine).

Mine came with a Thorney's map on it, otherwise the engine / exhaust is completely standard. The main aim for mine by the previous owner was the removal of the limiter and to sort the fuelling at low revs.

I can't compare what it was like as std, but yep mine seems razor sharp with the sport button on, linear-ish but pulls harder as the revs rise (in a linear way). I don't have any flat spots...


Agreed that dyno printouts mean little unless it is one car and done 'before' and 'after' some work on the same day / dyno etc.

Here is the Nordsmobile (like I said std, stage a stage 1 Thorney map):

If it was 369 standard what was the power after the remap??

[anissut]

If it was 369 standard what was the power after the remap??

It was 369.8 on a specific day. It was then 362bhp 2 days later. I believe it is 370bhp after map. I don't understand all this dyno stuff to be honest. All I have realised that dynoing at 369.8 on 1 day doesn't mean it will regularly turn that out. Same with the remap, might churn out 370 one day, 380 the next (unlikely) or 365. I'll post the before and after dyno map later on.

[Lee13]

When the air is cold,it is much denser than hot air. This raises the compression ratio which in turn produces a more complete combustion cycle and lowers the engines fuel demands. Also,the atoms in cold gasoline are more aligned and mix with the air more thouroughly resulting in better combustion.You’ve probably noticed you car having more power in the winter too. :thumbs:

Eeeeehhhhhhh heeeeeeeeeehhhhh, who's bad, I'm bad.

[anissut]

Ok, so here are the dyno maps. On 2 different days, 1 std and 1 with map. Hope it works as I'm not used to posting photos.

http://i754.photobucket.com/albums/xx182/anissut/CSL_Day2_Map-testing.jpg

I was told the following which makes sense:

2 different days, same map vs standard.

It shows the gains are consistent ignoring what the dyno readings say. Basically it's taking the correction factors out of the equation.

Also, notice the control point at 6500rpm. It's where I didn't change anything on the map so the two lines should meet in that area to show there is no BS going on.

So the gains are are around 10-12hp peak and more at around 4600rpm.

Guys, a bit of an update on this.

Car went into Andy at Murketts a couple of weeks back. Had a new clutch, flywheel, software, rtabs etc. all done under warranty. Also had the seat adjusted to tilt forward and that has made a huge difference to me, can really throw the car around even more now.

Anyway, got in the car at Murketts to drive home, turn it on and think, bloody hell, car's a bit quiet? Turn right out of the dealership and up to the roundabout and think, damn this feels a bit slow. Thought maybe I should turn around and go and get it checked out. Then I realised that the sport button wasn't on.

My remap from Evolve had programmed sport button memory. So basically the remap had been wiped when the did the clutch software. All I can say is that the remap was clearly bloody good because the difference was instantly noticeable. The remap also made the car sound louder and more mean so missing that as well.

Anyways, taking the car to Evolve next week to get it remapped for free again and may as well get my pads, hose and fluid done at the same time ready for SPA/Ring. Just thought I'd share with you guys.

He reckons he can get 300bhp out of my wifes X3 3.0d sport as well. Might get that done as well..........won't tell the mrs. though, lol.

[shimmy]

Anis

Know the feeling!!!

I think youll find BMW have a new SMG software update an dthis was installed on your box

Mine was done as well :bigcry:

I bet it slows the gearchanges down and saves BMW some clutch money;)

They've been making it slower for a while, I've got very, very early software on mine :thumbs:

;) Me as well.

[shimmy]

ive had mine remapped by Evolve and you guys coming in Wednesday are more than welcome to give it a go.

I had it done briefly before my recent visit to BMW but then returned to stock for a while but now have it back on again

Ill do a full review later after Bedford and Snetterton this week but it really IS worth doing

Hi Shimmy,

How much is the re-map and where are they based?

Best

You'll do well speaking to Rob @ DMS Automotive www.dmsautomotive.com U'll be amazed what he can get out of the S54 engine (safely) ... I was :thumbs: especially @ 6200 rpm where the CSL has a flat spot :whistle:

[Nords]

Remapping the S54 is only going to bring benefits low down. No one is going get much more than BMW from the top end...

agree regarding healine power but you have to try Evolves as the car pulls very differently

[anissut]

Nords

Totally agree with Shimmy. My CSL was the first CSL to be remapped by Evolve and they know what they are doing. Compared to STD the car feels stronger to me throughout the rev range along with a meaner noise.

We could do a few "tests" on the SPA/Ring trip as I would be surprised if my car doesn't pull harder than a std CSL. I'm sure Evolve do a try before you buy anyway, right Shim?

[shimmy]

Anis

I'm more interested if my car pulls better than it used to!

My data from trackdays should go someway to show if it is.

[_Nathan_]

Not really Shimster - you're 100kg lighter with a different diff, lighter wheels etc etc etc

I couldn't agree more :thumbs: ... mine feels much more muscular in mid range then it did before RR, so much so that I don't feel the need to go to 7900 rpm for MAX power, all of the time :whistle:

Agreed mate but I'm totally convinced mine pulls better than it used to. I knew straight away when I put my foot down on a dual carriageway on the way back from Murketts. It felt flat and didn't pull as hard at any point through the rev range.

I can't believe that people remap a CSL :banghead:
After all BMW may cancel your warranty :bigcry: I know a car they have removed the bmw warranty from after it was remapped :whistle:


Buyer beware

It depends on the dealer you go to for warranty work....

Theoretically yes, but when I was lokoing for my CSL, there were BMW AUC cars advertised with remaps, ap's and exhausts etc.

When it suits them:clown:
