Has anyone heard of DMS Engine Tuners
Discussion
Whilst on holiday i read an article in Evo about the above company increasing a 330d from 204bhp to 260bhp for as little as £600.
Has anyone heard of this company as fancy some of the action. 0 - 60 in 5.9 seconds
You may be asking why not get the details from the mag, unfortunaltey my female other half does not value such magazines, so she left in the hotel room when we departed

Yeah, I've used them on a number of occassions. For petrol models I'm not convinced of the improvement, but for diseasels - wheh hey!!!
It really does do exactly what it says on the tin - the 330d fairly flies when its been re-mapped, and still gave me 42mpg (average). Standard form doesn't really come alive til about 2200 rpm, DMS gives loads of useable grunt from as low as 1500 rpm.
In the 530d I had it taken as far as they were prepared to go, and except for a bit more smoke under extreme acceleration (not that you notice it unless you were looking for it) it made it into an accomplished car with an average of 33mpg iirc.
I'd love to try a 535d with their mod and if I get a diseasel again, they would be the first port of call.
My only concern would be on a new car and the warranty impact if it was discovered that you had made the mod, but it is allegedly undetectable under normal conditions, only an indepth trawl of the ECU map would show the changes. TBH, I preferred their original piggy-back system that you could take off whenever you wnated to. If its a 2nd-hand car, then go on, fill yer boots!

This is where it confuses me. Currently i am driver of a Porsche and i have heard DMS used loosely on a number of occasions however I don't think they are the same company
What is more frustrating is the fact i cannot find their website. I was hoping they would have one? but so far no luck. £600 is well spent by the sound of things

I have heard good things about DMS (it is the same company as the Porka tuners - all things Turbo really!) but I was at Power Engineering last week and chatting to Mr Superchips and he said they are launching a new diesel chip at the moment that he claimed was the cream of the crop - might be worth giving them a call.

Have used DMS on an M3 and a 320d with equally pleasing results. The 320d is much gruntier and uses less fuel to boot! Recommended...

What is the system they put on the 320d? Is it piggyback or a rework of the existing ECU? Have you taken it to s dealer yet and if so did they sus you out? I'm really tempted with this but worried what it will do to my free servicing deal and warrenty.
Thanks

The piggy back (old) system was easy to remove. IIRC they now only really do the re-map on the ECU - as I said earlier, its not noticeable by BMW during normal servicing, but if you have a major engine problem they "might" do a full investigation and see the re-worked code.
It all depends on whether or not they think you've been playing with it or not. Its all done through the standard diagnostic interface, so no seals broken etc....
I wish I'd kept my old piggy-back box!

Mr Power Engineering said that the main risk with modding the ECU itself was that if the dealer actually drove the car, it would be blindingly obvious it had been fettled, so didn't advise this on cars under warranty. The piggy back boxes can be removed without a trace in about 15 minutes. The ECUs are effectively wiped so the old map cannot be put back onwithout reversing the process. Also, the piggy back boxes are often universal with minor tweaking so can be taken off and used on the next car if it is similar.
I have become an expert over night!
DMS offer on the older 330d engine a piggyback system that plugs into the ECU socket, press a swith to download new info and then remove. If you require the ECU setting to the orginal spec then plug the unit back in, hit the switch and no one is any wiser.
However this does not apply for the the 2003 upwards 330d, once set there is no turning back.....but thats not a bad thing
Can't help on the 320d though, i forgot to ask.

Thanks for the enquiry. Dual system does not operate on the 320D which uses the later Bosche EDC16 ECU. We have to programme this direct but end results are undetectable by BMW service and diagnostic equipment.
Great but will they guarentee that? IE if the dealer takes a look at the code and noticed mods have been done.
