Re-mapping a 335i, 335D or 535D, your experiences
Discussion
Hello guys,
i currently own a E46 M3, i want to buy a newer model BMW, i had (and still am) considering a E60 M5. however i do 25/30k miles per year. because of this and the DMS re-map reviews ive read about the 335i, 335d, and 535d i am absolutely intrigued. do any of you guys own any of the 3 cars mentioned, have you had them re-mapped and how are you finding them? maybe someone else out there has made the transition from an E46 M3 to one of the 3, how are you finding it?
any feedback/thoughts appreciated.

I've never driven any M car, but have spent a fair amount on mods for my 335i(LSD fitted, Downpipes and intercooler siting in the garage waiting to go on). From what I've read up on remapping, a few choice mods and good remap will take a 335i easily over 400Bhp. But am not entirely convinced regarding the cooling capacity of a stock N54 engine let alone one tuned to give produce 100Bhp over stock figures.
Even in this cold weather I can easily send the oil temperature on my unmolested engine to 130 without really trying, given the infamous "limp home" mode apparently kicks in at 150 I'm looking into getting a oil cooler upgrade before I start upping the power. My 335i cost me £20k, by the time I've finished fiddling I will have probably spent £5-6k on mods which I'll never get back come resale. If the wife would have allowed I would have quite happily spent £30k on a M3 and keep it stock but she felt the M3 would attract too much attention especially if she was driving it by her self, where as to most people a 335i looks pretty much identical to a 320d!!
I love my 335i but it's no M car, the E92/90 M3 is coming down in price quite quickly now, if you can afford the running costs I would stick with a M car. Luckily the wife likes the looks of the new F10 M5:-)

I know someone who went from an E46 M3 to a mapped 335i (don't think he's on here though) which was owned by BMW and had the re-map along with some other engine tuning (not sure what exactly), massive brakes, uprated suspension etc done before he bought it. He hasn't had it on a dyno, but the bloke he bought it from said it was pushing out over 400bhp, and the in-gear acceleration was streets ahead of an M3. Don't get me wrong, he said it was a completely different animal compared to an M3, but if you're doing 25-30k a year, I would strongly recommend them over an E60 M5.

Had a CSL and a 535d sport touring that was mapped by DMS.
The 535d is a great everyday car, but not edgy in the slightest.
Then went to just a 335i sport touring that was tuned and extremely quick, faster than the CSL but pretty dull, after being lent a 330i I realised that it just wasn't for me really, so sold it and bought another M3 and an older Merc E320cdi estate. Perfect combo!!

I have an Evolve map on my N54 335i, its now really quick in gear and very flexible too but it lacks the throttle response and top end drama of a good ( i.e M Power ) NA engine.
400+ lb-ft of torque from the map can make things entertaining in the wet and hightlights the need for a proper LSD; a Quaife diff is next on my 'to do' list.
Imho Winter tyres are needed from November to March, particularly if the car normally runs on standard run flats.
Luckily I've not seen the 130 degree oil temperatures that Gangzoom has seen, mine hasn't been over 115 yet, even when trying very hard. A bit of Googling earlier suggests that some, but strangely not all, 335is have an oil cooler which might explain the difference. Apparently with the ones with the oil cooler have vertical vents at the front of the drivers side wheel arch liner. I've checked my 2007 E92 and can see a radiator type assembly through these vents.
Fuel consumption has been 1.5mpg worse since the map but that's probably becuase the extra power encourages you to 'play'

Ive had an E46 M3 and since that car im on my 2nd 335d Tourer, both of which have been remapped
I sold my M3 as it was costing me far too much money in maintenance than i was comfortable with, and we got dogs, so needed an estate, the 335d fitted the bill nicely.
The 335d isnt as polished in the handling department as the M3, it doesnt have the charachter or the noise, but to be honest 95% of the time that makes no difference to me, i dont "miss" the noise of the M3 like some say they do, and being 110% honest here i prefer my 335d, i drove it back to back with an E46 M3 recently and i was glad to get back into my 335d
The M3 isnt as quick as the 335d either, from a rolling or standing start, which does irritate M3 owners somewhat

Seriously? Your mapped 335d touring is quicker than an E46 m3? Wow WTF

All EU spec 335i comes with an oil cooler, to get the temperature up simply do a short run ( 5-10 minutes max) with whilst keeping the rev >5Krpm constantly (e.g. what you would do on a track) and your oil temp will easily climb above 120. Equally by than your find the standard brakes would be shot and fading badly. Companies like AR design do an additional oil cooler, and you can always get a big brake kit from a company like AP racing but its all £££s. The point is that a 335i/335d is basically a normal 3/5 series which happens to have an engine thats good enough to be in a M car..but is let down by the rest of the package. I love my 335i, its good for what it is, but no matter how much I spend modding her my friends E90 M3 will always be better in every respect.If you can afford an M5, go for it!!! As said if the wife had been happy with a M3 I would have bought one, so I'm having to "make do" with a 335i..which isn't all that bad

I think the performance upgrade that BMW offer for the 135i includes an oil cooler .
The performance Kit only give you an extra water cooler and big fan, and its costs about £2K for parts along. Edited by gangzoom on Monday 31st October 16:21

Yes both my 335ds have been tourers, I've had both remapped and yes from both rolling and standing starts they are quicker than an E46 M3, not as dynamically polished obviously but who buys a diesel estate for dynamics!! I love my 335d and can't think of any other car that would be able to replace it

Out of interest, have any of you had problems with BMW and remapped engines? My car is just out of warranty and into extended, fancy a remap but the one thing that puts me off is a warranty issue.
A lot of the remap places claim to pay for any warranty claim which BMW refuse as a result of the remap. I know Evolve do this.martin mrt said:
Ive not had any engine issues with any car ive remapped, including my 2 335ds, i have an extended BMW warranty on my car and its been in for warranty work, they did pick up on the remap but there were no issues having any work carried out
How did they pick up on the remap ? Did they drive it
