Evolve 125i ECU Tune +52 BHP +40 lb.ft torque

[Imran@Evolve]

As most of you know the Euro spec 125i has the 3.0 engine and already have the 3 Stage Intake manifold/DISA from the factory. With our ECU tune we can offer 130i levels of power. Even better for those not in the UK we can offer this upgrade world wide with our Evolve-R end user OBDII flashing cable.

Dyno's below are using 99 RON fuel.





Flywheel Power



Wheel Horse Power



Evolve-R



This is how it works:

- We send you the cable with software
- Install the programme on your laptop (Windows XP/Vista/7)
- Plug the cable into your USB port and then to your OBDII port
- Click the 'identify ECU' button
- Read the file by clicking on 'read ECU memory'
- Email us the file
- Await for the modified file to be sent back
- Click 'programme ECU memory' button and select the new file

Initial read time is 1 hour and write time is 15 minutes. After this it takes 2-3 minutes when you want to return it back to standard.

You can then select the original or the tuned software. Handy for dealer visits if your car is under warranty.

RRP is £625 but we have a launch discount of 10% for orders placed in December 2012 making the price £561 GBP plus shipping.

For those in the EU VAT at 20% has to be added to the price.

mmmmmmm : ).
How much gains are there for the 128i that doesn't have the 3 stage disa valve?

Woa, merry Evolve-mas

Some Questions:

Is 99RON equal to 93 USA octane in AKI?

Does the tune utilize a retrofitted DISA manifold from 130i/125i/330i etc?

Is the top speed limited raised?

Is Redline RPM raised?

Is throttle response changed?

Can the cable be used to scan codes and use it for function Coding? ( ie DRL, hidden menu's, windows rolling up, etc)

From what I recall the 125i is rated at 218hp, so @ flywheel shows a 14hp discrepancy. Therefore the 125i can be rated at about 270hp.
If this was a 128i I predict the flywheel number to be near 215hp. So the gain for a 128i with n52 & a DISA would be 35-40 hp?

If this is true, then this is better than sending ECU to Germany for their 280hp tunes. Can I start dreaming about a 270 hp 128i yet?

For a non DISA 128i n52 the curve could look more Exponential/Concave Up, I posted (here) a find from a tuned German grey market 128i that had the same numbers euro tuners get at the top end. I am not sure how high the hp would be here, but it should be near the same top end power, just without all the DISA bonuses to hp and tq in mid-range

Would this even work for us NA 128's? And what are the actual gains to the tires and flywheel? Looks to be about $900USD though.......

[ivan-128i]

It will be great to see a dyno of 128i NA !

[631twentyeighteye]

If there are any east coast tuners wanting to dyno a 128 before and after the DISA intake, i'd be willing to be a test subject! once i buy the intake that is..

This is a bit off topic, not really tune related. However, I will post such a dyno when I can. I though I would in Oct, but I was rushed to my 17" winter wheels because my alignment was off and it ate my dying run flats. So doing a dyno on winter wheels wont be too accurate but so it wont be the same as with new summer tires. At least i will have the same wheel radius.

[631twentyeighteye]

Yeah sorry to get off topic! Just so hard to find any US tuners for us N52's. This does bring more evidence that more power can be brought out despite being NA. I'm curious to see the difference between a tuned 128 none stage 3 intake and the one tuned above. If the curves would really be as drastic as you suggested above.

Yes 99 oct is 93 USA equivalent.

This is a 125i which already has the manifold and DISA from the 130i fitted from the factory.

We haven't raised the rev limit on this one but we can if required.

Yes we can take top speed limiter off if required.

Throttle maps are changed to be more aggressive.

The cable can read and clear DTC's and flash file into the ECU. Nothing more.

We do not have any 128i's here but in theory it should be possible to get exactly this power if the car has the required retrofit parts form the 130i/330i. The ECU is the same and map locations are the same.

On a 128i without the required retrofit would have gains of around 10 BHP and 8-10 lb.ft torque I would guess.

Hmmm, I would go for this if it didn't cost $900. Thats a little much for such small gains without the 3 stage intake.

[JimD]

It's all guessing but the dyno runs of the guy who put the 3 stage on but didn't re-tune suggest to me that the 3 stage inlet is not a magic bullet (he didn't do a before and after but others have posted a stock 128 at about the same rear wheel power - but the car that was changed had some miles). Perhaps it's a lot different with the tune. I wonder what removal of the carbon filter on our inlet + possibly an intake + possibly a cat-back exhaust (i.e. magnaflow) would do versus the 3 stage. You could, of course, do all these things.

I'm wondering if the 3 stage doesn't do more in the mid range than the upper end where ultimate power is developed. Part of my speculation is that my car feels pretty strong above 3,000 rpm but a little sluggish below that. I also tend to assume 2 stage = one stage for low rpm and another for high. Same logic suggests to me that 3 stage = low, medium and high rpm intake runners.

You are correct, the untuned 3 stage DISA is not a silver bullet, but it makes a noticeable change in character even without any tune. Based on other peoples dyno's, I predict without a tune that the gain is up to a maximum 10 hp and 15 tq.
I noticed that my rears broke traction more, the power surge or bump after 3.5k prm feels great, the RPM climb quicker & aggressive after 3.5k. My father who didnt drive the car for about a week noticed too on the first drive, I don't think it was the high of a successful DIY as we kept quiet for most of the drive to stay unbiased and analyze. A few days later I noticed the low end torqe boost in traffic and parking lot situations. I'm very satisfied and as a result reluctant to jump to just any tune, especially since I know what European tuners can do.

I must admit that both Evolve and Eurocharged have been great at answering questions in detail, and AA tune has a great FAQ thread. Other tuners (mostly those that tune m3's) have responded to claim 15hp gain, but have yet to show dyno's or inspire confidence in their n52 products. I guess we are just not their market of focus.

Thank you for answering my questions. Must be a great product.

How much would shipping be to USA, Canada and Australia? Most of us here are from there.

What options are available to customize the tune? Which characteristics can be tweaked?
I have read that other tuners can adjust throttle response to be more or less aggressive from the default tune, addressing certain areas of the power curve for more or less gain and coding out the primary catalyc sensors on exhaust manifold.

If we are not tuning for the intake then the cost is $799.

[jb2178]

Those of us who have a SULEV 128i are running the N51 engine, and it does include the 3 stage intake if I'm correct, so it should be essentially be the same as the 125i but in 3 liter form. I believe the 125i has a 2.5 liter engine...

This could be VERY interesting.

[andrey_gta]

125i is a 128i 3.0 with DISA & a de-tuned ECU

The N51 engine has not been documented well with any tune

We have stock in both the US and Australia.

For US sales you can go to Evolve US

For Aus sales you can go to Turing MS

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.

Correct.

[jb2178]

So will this work on the N51 engine?

[Imran@Evolve]

I would have to do some research to see what components this engine uses with regards to the intake etc.

We don't have them in Europe.

[jb2178]

Here's a link to the 128i's (N51) intake manifold: http://realoem.com/bmw/showparts.do?...56&hg=11&fg=40

It has a part number of: 11617559523
The 125i according to realoem has a manifold part number of: 11617559523

That's a positive sign. The N51 has slightly lower compression than the US N52N but it does have the 3 stage intake and a couple of additional catalytic converters... that's about all I know.

Thanks Imran for answering the questions.
I asked alot of the same questions that are asked by others. People are starting to use catless headers and some of these questions come to mind.
