i thought the maps were standard maps? surely you would have paid big bucks for a ''live map''.

I know the tuner a little (ESS tuning in Norway), they used one of my earlier cars to develop a supercharger kit.
Because I suffered from drivetrain vibrations, he had to do some changes.
So he just changed the map while I was there and we ran the car at the dyno between each new map to check the result. It took a couple of hours.
The result was the reduced torque down low that we were looking for, and 10-15 horsepower more between 2700-4300 rpm. Then instead of a drop in power above 4300 rpm, we managed to get good power all the way to 5000 rpm.
So its clearly important to use a dyno to check the result when you chiptune a car, the car felt good before the changes in the topend, but clearly there was important things to change.
The reason why my car wasnt perfect after the standard map, was that the car he originally used to develop the chip had slightly different software......BMW constantly change the software!

Personally i would be pissed off especially as it looks like you have lost all top end power with it being made at 3800 instead of 4800 which my and your 2 stock cars did. As ALL 335d, as they all rev hard and pull well to the redline.

Is this because he could not get the car to 5k due to the torque of the car forcing the rollers or because there was no more power afgter 3800?

I think your car was remapped in the factory Carlos

all this dyno talk makes me want to do it!!!

This tuning miss something important, it should have more power from 3800-5000 revs!

The tuner needs to learn the map better to be able to complete the job properly.

Has anyone spoken to simon about these results yet ?

That would be very interesting.

I have to say that the map definitely feels like a lot more than 10bhp. Surely if it was just that you would hardly notice it - but I know that my car felt as different as Jekyll and Hyde after getting the job done

[Evil Diesel]

Final thoughts - I attach the before & after dyno read at the wheels. You can compare this to Peppernicks dyno (also on a dyno dynamics machine) at this link -

http://www.ca-automotive.co.uk/show_...ucGpwZWc=.html

He is showing another 10 hp and this apparantly read an estimated 350 bhp on the flywheel. Given that my car has only covered 2,000 miles and is still fairly tight you should be careful before jumping to too many conclusions.

On the road the difference is very noticeable.

And Carlos has had a go in it!!!!

[EVOgone]

To be honest all the graphs look really poor. Huge torque spikes so it feels a lot faster than what it is. Certainly noone has proved the 320hp barrier never mind the claimed 350 everyone keep talking about.

None of the graphs show any real top end power and a loss of the flat std torque curve, not good really considering all other 320d 330d maps are all mirroring the std graph but more HP & Torque. Wheelspin shouldnt be an issue as on the same dyno they have plenty of big Hp cars on.

DMS one may be a lot better but need to see a graph of it.

[Evil Diesel]

I am neither defending or criticising the map.

The toque does feed in rather than spike - the dyno graph readings are a little misleading here as the power was being fed in between 1600 - 2000 rpm.

Thanks for reminding me that we had that particular graph Tony, mine must have got blown in the back of the car!

So just to echo Tony's sentiments's - Nicks graph on the CA link shows 269.1.

Tony's car shows 259.1 and has only just covered 2,000 miles.
My car shows 263.2 and has covered approx 4,500 miles.

So give both car's another 10,000 miles and you can draw your own conclusions.

Besides, at the end of the day, I'm happy with the resultant increase in performance, one must not forget the primary purpose of the remap, must we,better MPG, the increase in performance is merely a bi - product of the modification

[Evil Diesel]

Cheers Ian - you have just reminded me - I haven't needed to tank up since the upgrade. So any statisticians out there please draw your conclusions from that!

[dxb335d]

I will be re-mapping purely for performance.

''I care not for MPG but ONLY FOR MPH''




Mine made 257bhp at the wheels stock. But you guys do have a far bit more torque now, but still miles off what the map should deliver, 350+bhp and 530ib ft IMO.

You guys started out with more HP than nicks car when there were all stock, but re-mapped less HP.

I a decent improvement, to pull past E46 m3's at the moment i live with them easily, but want to ''pull past''

Well, if you can stick with us without a tweak then well done indeed.

If not then you can admire my shiny rear end

OK , i think im going to take my 335 DMS D down for a show down to see what the lady has under the hood. I've done 16000 miles and shes flying as the RS4 on the A49 found out today
Will try to book in asap and then show the results.

[dagjohnsen]

At 4500 rpm these 335d`s have around 385 NM, thats what a remapped
325d has!

With the big turbo (working the topend) these cars should deliver more, my guess is that this map is OK up to around 3500 rpm, then something happens that the tuner doesn`t control and the car has less HP than standard above 4150 rpm, thats crazy!

The car should have around 30 horsepower more around 4000 rpm and keep that power up to 4500 rpm, with a small dip up to the rev limiter. That would really mean alot when pushing the car hard, making the car feel way more agile and revhappy. Also top speed will suffer alot with that map!


A really fast car always has the torque as high as possible in the revrange, this map even if it will feel furious and crazy is simply terrible from a pure performance point of view. The tuner should improve it asap.

I know that torque is fun, my car has 458 Ib-ft (622 NM) torque now between 2250-2750 rpm, but earlier on I had even more and also below 2000 rpm. I took it away, too much stress on the drivetrain, vibrations on heavy loads.

i feel this map must be ''incomplete'' or not downloaded correctly?!

The Peppernick dyno looks a little better, at least the new torque never goes below the old one. But it really equals 317 hp at the crank with a 15% calculated powerloss, not more.

I think there is more power to find in that engine

[mikem]

I think before anybody says there`s something wrong with the map, it needs to be run on a different R/R.

Dag, the 335d are all autos, so you have to allow closer to 20% loss for the torque converter.

There`s def. more in the engine, DMS told me when they were doing mine that 360+ would be possible but the first thing to fail would be the fuel pump.
