M135i DMS Remap + Eibachs

Post by R5YUP » Sun Jan 31, 2016 10:39 am

Posted this earlier on PH.... thanks for all the advice chaps :)

Bit of context.... I've had the car 3 years from new and although it's perfect for my needs (labrador + my wifes daily drive), the handling is really quite suspect (read: very) when you're at maximum attack - and it's certainly not got the character, charisma or finesse of the best m cars (well, it's not actually an m car is it...!)

However it's still a really compelling package and before starting to look again at replacements with considerably higher running costs (RS4s and C63s) i though i'd give the baby M one more chance to shine.

The remap is lovely although not mind-bending (however my bar was a ballistic 996 Turbo with 525bhp - that car reset my understanding of acceleration). My car dyno'd at 322bhp pre-map and 376bhp post-map. However i must say this was on cheap 95 supermarket fuel (i can only blame my wife for this) and i understand from speaking to other mod'ers that putting some proper fuel in makes a tangible difference with remapped cars. After 'negotiations' with my wife it's now running exclusively on VPower and it does feel sharper - and DMS have welcomed me down for another dyno run, which i'll do at some point in the future. Subjectively, i'd guess around 390bhp now - but i will get this verified and report back!

It is fking rapid.... but the real gains are in the higher gears where the additional torque means you can pull hard in 4th and 5th from low down. It absolutely shifts. And above 100mph it's a completely different monster (although obviously i haven't done this).

Do you need a remap? Probably not, the car is already seriously swift, but for me, totally, yes! I love the power and it just makes the car that bit more exciting. There are cheaper options (JB4 seems very popular) but i wanted the reassurance and warranty from DMS, who were superb all-round, i'd recommend them, excellent service and passionate guys. Also they have tasty machines down there and mine was by far the cheapest thing around!

As for the springs......

fk ME. They have totally transformed the car! I have never modified, or even been tempted to modify a car before - and i must admit i was totally totally sceptical about the gains of doing this, imagining i'd be left with a terrible ride. But after reading loads of postive reviews on babybmw.net (the best m135i resource out there), they seemed like an inexpensive way to dip-my-toe in and see if i could sort out the dodgy handling.

Wow.... noticeably less roll in the corners, it really sticks to the road and the jittery ride that sometimes felt like it was about to spit you off the road has completely gone. It's firmer but not crashy, still a very supple ride (i have adaptive dampers), I am hugely surprised but even more hugely impressed - i did not expect this.. It's now got a go-kart feel, in a funny kind of way almost similar to my old JCW. When my wife first drove it to work afterwards, she called me half way to tell me the car felt AMAZING...!

It now feels like a proper m car, and i've gone from being a bit non-plussed about the car to loving it.

So in summary, if you have concerns about the handling of your m135i, stick some Eibachs on and let it blow your mind. The car is now keeper...... smile

The question is now, whether to go all out on one of the Birds suspension + LSD packages smile

Cheers

Nice little writeup. Glad your pleased. I agree the difference in 4th 5th and 6th in my manual is absolutely epic. 6th pulls like 3rd used to.

Imagine another remap on top of that to what some of us stage 2 folk are running :lol:

Eibach's are the future, very nicely balanced. Not too low, not too uncomfortable, not too rolly, just right. Goldilocks Springs!

Thanks for the DMS feedback, did they remove the ECU to reflash it?

I've got to admit that I'm already thinking about more power..... It's really seductive!

Nice review!
I'm very tempted by a TMC/JB4 at the moment. Whilst my standard car is quick I do miss that - Wow feeling I got from a few previous cars but that's probably down to the linear way it delivers its power as I know the standard x135i is just as quick.
How does the car put the power down with the open diff? Any issues with traction?

What drop did you go for with the springs? If I lowered mine I wouldn't want to lose that every day ability or compromise the 5 adults in the car relative comfort.
I'm only up the road from DMS too!

I feel like a photo is in order of yours on the lower springs!

Thanks, Neil.

I think so, although I must admit I was relaxing in the lounge at this point watching Fast N Loud on Discovery Turbo!

Took a couple of hours, they showed me where it was under the bonnet (I always assumed it was the obd port in the footwell) and explained a few things needed removing to get there at which point I left them to it.

I was also a bit distracted by the Carrerra GT, GT3 RS and Challenge Stradale they were working on at the same time, lovely!

I should add that they also fitted my springs, did a Geo and a brake fluid change for me too

No traction issues so far, although has been a touch damp so not 100% floored it in first yet. Little bit of slip in 2nd but minor and and very controlled. Must say the springs have really helped with traction, not sure how or why but feels much more stable when dragging from the lights.

Not sure on the drop actually, I didn't check! From others on here I just know it's not as low as the h&r which is why I chose them. Will sort out a picture soon, I actually don't think it looks a huge amount different!

You won't lose any daily ability on the eibachs. In fact you will gain more.

Hopefully if you go back to DMS with your cars DME fully adapted to SULP, DMS will adjust the remap else you won't get best remap gains after moving from ULP to SULP

Yup, should of said, I had the springs done a few days after the remap and it was during this time I was running vpower. They tweaked the map when they had the car back but sadly not enough time for another dyno run that day.

Was this Dms in Southampton by any chance? I'm only 10 mins away, did they fit your springs for you? And if so how much? Cheers

Is it worth putting eibachs on a lci with adaptive dampers? I've been looking into it but don't really have the appetite to spend the money on a full birds package
