I'm pretty sure the N51 has different injectors than the N52. I messed around in RealOEM one evening trying to figure out the differences between various N52s and also included the N51. I don't know if the injectors would affect power capability but they could.

Good point, it also could just be due to the lower compression. I'm still excited because this tune seems to need the 3 stage intake in order to get peak gains and the N51 should already have it. Regardless it would be a great bonus to those who have an N51 128i if we could spend $900 and gain 30 hp. If that's the case I will be forever grateful that I purchased mine while living in Rhode Island.

Evolve should send me a unit for research and development - I'll foot the bill for the dyno runs and send you guys charts and data. My N51 is still stock and only has 46,000 miles on it!!!

Hi Evolve, I am from Mexico and have a 2006 130i euro spec. how much of a gain could I see? my car is rated at 265 from the factory. and also how much is your product for my application?

Thanks for posting up this info.

Without giving away any trade secrets, how close to the factory 130i tune is this setup?

What I'm trying to understand is if I were to install the 3-stage intake and get this tune, would my 128i be making power pretty much the same way as a 130i does (fuel mixture, timing, valvetronic etc.) or are some of these items pushed further than on a 130i?

Also, if you already have the increased top speed limited with the M-sport package, is this left unchanged with the tune?

thanks for the help.

Us n52 engined ppl are so hungry for tunes LOL
here is a 130i dyno from 2010 with Evolve at about 280hp: http://www.babybmw.net/viewtopic.php?f=56&t=20642

EDIT: Woohoo 1k Posts

So real quick question for some of you that have done the 3 stage manifold upgrade, is this the only part needed? I may think about getting one if it really makes this much difference

Yes you just need the complete manifold ( manifold, small disa, large disa, 6pack of gaskets). Disassemble the used manifold and wash with soap, take your time.

As far as if you need it, well look at the German tuned 128i non disa dyno that I liked to above. Compared to the 125i or 130i they are missing the pumps and valleys in the hp and tq curve. Mid range power certainly benefits with the manifold.

As this is a new product I am awaiting details to go up on both sites but this should be done very quickly.

Custom tuning can be done but no necessary on stock cars and would incur additional costs. We pay a lot of attention to throttle mapping and have never had customers complain about the way we do this. The tune gains what it gains. If you have less low down does not mean you can have more up top on a normally aspirated car.

Why would you need to code out the primary cats if you are not removing them? If you are then of course we can code it out.
OK, I will give this a go. I want a custom map that gives the most power possible, how much will this cost?

I currently have a 6AT 2010 125i that already has an ECU flash from another tuning company but it is still too conservative. I dont mind having poor fuel economy for this tune if I can just flash it back to the previous map if I dont require max performance.

A few weeks ago on a Dyno Dynamics machine my car made 146.5rwkw (196hp). On the same day a stock 6MT 130i made 156rwkw (210hp).

As you can see the air:fuel ratio looks pretty conservative and I am sure more power could be had if you could get more fuel in.

I will contact the distributor in Australia and see what they can organize.

i think its more about parts then just tuning air:fuel ratio?

Do you have a full exhaust, cold air intake, etc?

because if you don't upgrade all of your parts they act as bottlenecks.

They can tune the engine all they want but there is a point of diminishing return. At that point you are just increasing the chance of ruining the engine for no reason.

The N52 isn't really tunable, especially since the engine is part magnesium that makes it lighter, but can handle less power load as well.

But you are right that the tunes are somewhat conservative, but I think the majority want this as most of the cars are daily drivers. So, you probably could ask for something more "aggressive" but there isn't really a point unless you have full upgraded parts to complement.

Now, if you really want to upgrade the engine itself, then it would require lots of $$, such as for bigger injectors or something.

Another thing to note is the transmission. I believe the 130i uses a better transmission then the 125i and 128i and additionally different gear ratios.

I think 275 HP is probably the normal limit. Intake, DISA, full exhaust, and a good tune. After that, you are talking about serious $$ which at that point I would just get a 135i or something :P

Intake ~250, DISA ~400 i believe, Exhaust ~1000, tune ~800.

Thats a lot of money for only ~50 hp gain

Dont need a new intake as the factory 125i airbox is fine. Dont need a new exhaust as the 125i only has one set of cats and not 2 like the 128i. Dont need a DISA manifold (already have it from factory). All that is needed is a more aggressive tune.

A more flowing exhaust always helps. Intake could certainly help more. Along with a tune and the stage 3 intake(mine doesn't have) would yield the best gains.

I will test the affects the adjusting the fuelling on our test car and report back if there is any benefit. Obviously you would lose some economy and as the stock fuelling curve is biased towards fuel economy.

I agree. On the 125i I don't think there is much more to come from changing intake/exhaust. From our experience BMW exhausts on Euro spec cars are ver well optimised. Certainly no or little gains from changing the rear exhaust. The cats maybe - but expensive part to change and not sure how much of a market there is for this.

I have some seen some good gains from the Simota intake on the 130i but am yet to test this myself.

On our dyno the 130i is still making more power so maybe the cat section of the exhaust is more restrictive on the 125i.

Don't have enough data to be sure but the 125i Auto which was used for development is not making as much power as 130i manuals which have been on our dyno.

If you already have top speed limit removed then this remains unchanged.

Imran,
Browsing http://www.evolvetuning.us/ i see that the 128i stage 1 and stage 2 tune share the same description & HP increase, except that Stage 2 mentions the 3 Stage DISA manifold.

Can you clarify why there is no difference in HP increase.

Is this an error?

That is an error. Will get it sorted out.

We don't have them in Europe.
Anxious to see if this will work on N51. It looks like a few of us have them and are interested even if the gains aren't quite as substantial.
