2008 125i  [10.00]
EvolveR tune for 125i

Had the tune done through SouthernBM - thanks Andrew
Before and after Dyno attached - a bit dodgy and out of calibration but the improvement is consistent and significant across the range. Blue is power and green is torque
Conditions similar, if anything, the later dyno was on a hotter day - 18 vs 23deg air temp.
Peak power 121kW vs 96kW
peak torque 2850N vs 2600N
The car has been tested previously at Advan in Sydney and produced 129kW peak power about a year ago.
I have aFe intake and BMW PE exhaust installed.
Personal impressions - not much change at lower rpm, but past 3.5K feels more eager to rev and noticeably faster to pick up speed. Overall the character of the car is slightly more aggressive, but not markedly so unless you flog it mercilessly. I haven't taken the car to the track, but that's where the improvements would show better I guess.
For the cost - $1299 installed - I am actually pretty happy. Over 20% gain and across a decent rev range. For a NA car that's remarkable.

Congrats! Glad you are happy with it. This kind of power increase on a NA car is rare so enjoy.

Awesome stuff. This will be one of the first things I'll be doing when I pick up a 125i.

Now, if only I could find a decent one!

Manual. There's a few nice ones I've seen for sale recently but I'm not into the colours. I'm pretty fussy with what I'm after.

Ideally:
  • Manual
  • M Sport
  • I-Drive
  • Black, White, or Gunmetal
  • Less than 90,000km
  • Less than $40,000

Just a matter of waiting for the right one to come along I think.

Hi morris86 and welcome
I bought a 2010 125i coupe earlier in 2013 with similar criteria to yours, although I wanted low km (<40k). As you may be discovering, there are far fewer MT cars than autos available, so in the end I settled on a non M-sport car (with some regret) as it ticked all the other boxes. Be patient and you will be rewarded
In the meantime, enjoy researching & contemplating possible mods ...

People in the tuning business will tell you not to look at the top numbers but rather at the area under the curve and consistency of improvement across rev range. Either way its 23% more killer wasps and much more responsive.
From about 3K revs the difference in attitude is noticeable with the seat-of-the-pants dyno
4.5K on - its a different car, almost
no idea what made BMW de-tune 125i compared with 130i....

Very accurate description of the change in behaviour of the car. My mate had his auto 125i tuned by Imran a couple of months ago, and he's very pleased. The "different car" thing quoted above is so true, and it sometimes catches him out. But a good indication of how refined this map is, rather than it being a brash, undrivable, hectic drive, his wife drove it sedately for a couple of days (without knowing about the tune) and didn't notice!

So a sophisticated and refined tune that can rip your face off at the press of a throttle.

Two years on, and my "mate" is still very happy with his evolve tune. It's been at BMW dealer a few times and nothing noticed, nothing overwritten. Thanks Imran.

I took advantage of the low GBP and bought this tune a couple of weeks ago.

Had a bit of drama installing the tune, car wasn't starting for a few days but after a new stock tune file, it's been working without drama since.

Only thing I felt was lacking was that the delay in throttle response from when you actually press the pedal to the car accelerating is still very noticeable, even after the tune. I had hoped that this would be reduced or eliminated but it seems that it hasn't.

Also, not sure if I just didn't notice it before but there is a distinct knocking sound on downshift (AT) at low speeds, i.e. around car parks, coming to a stop, etc; will continue to monitor.

Sorry to drag up an old thread, but I'm very interested in this tune.

I have just sold a 130i, loved the power, didn't like the hatchback body or the fact that the car was getting old and tired.

I am about to purchase a 125i and am hoping to get similar amounts of go with the Evolve tune.

Imran has quoted 595 GBP delivered. Is there any benefit to purchasing from a local provider (besides the warm fuzzy's of supporting Australian). My understanding is you receive a tuning device and its just a matter of uploading a copy of your tune and downloading a copy of the upgraded tune from Evolve and applying it? Do I need to supply a trickle charge to the battery?

I'd really love to hear from anyone else who has applied this tune. The dyno results from the OP are impressive, I'm hoping I can achieve the same.

Maybe you are not well versed on bmw product positioning. Historically they will often do dubious and questionable things to reduce the appeal of the low end cars. It redistributes the perceived value, so the base models can be attractively priced, while the upmarket models become worthy of a higher premium price.

As far as I'm aware, there are no local dealers for this Evolve tune specifically.

It'll also be a lot cheaper purchasing from them overseas due to our strong dollar and lack of tax.

You are right in your assumptions, I would definitely suggest using a treacle charger while tuning.

any issues so far with your car after the tune? Did you buy direct from Evolve?
