*sigh* don't feed the trolls, people.

 

Here in Europe we already have a few tuners that cracked and tuned the new cooper S, I believe Evolve was the first.
On Youtube you I found that Autotune Heinz and Digiservices also have their tune ready:

then why are you griefing? (no need to answer)

 

New to the forums here, have a random question...

I don't know much about ECU tuning but how does it work exactly? I've changed out my oem intake for a NM-eng hi-flow kit and I've swapped my exhaust for the quick silver sport system. I am noticing now however that I may have lost a bit of power or that there is more turbo lag when I accelerate. The parts were all correctly installed I believe and I haven't had any functional issues with the car. I wanted to know however, if I tuned the car, would it change the parameters so that It would be optimized for my new upgrades?

Secondly, when visiting the dealer, if they have to do a software upgrade or something with the ECU, will the tune be erased?

Anyone is free to answer, greatly appreciate the knowledge.

 

Do you know if the AccessPort ECU tune will eliminate the Torque Steer Elimination Retrofit that is currently offered at a few dealers?

Apparently the 2011 models have some updated steering software, and I'm thinking about asking my dealer about installing this on my 2009 factory JCW. I'd hate to pay for that, get the AccessPort and then erase the update with the AccessPort.

Thanks

 

does anyone read the thread anymore or just post questions in the thread without reading any of it?

 

yeah - I read the thread, but it's 42 pages long now, and I didn't see if this would affect the torque steer update for the 2011 models that I may ask my dealer to perform on my 2009.

I'm wondering if you do anything other than berate posters on here. I'm getting ready to spend nearly $1000 on this thing and I'd like to make sure I've done all my research.

 

Let me ask this...do you think that the AP would override something like this? To me it seems that it is unlikely to touch any part of the ECU that deals with steering and yes....the answer is here in this very thread. You may have to go back just a few pages.

 

The way that the tuner works is that it changes the software in ECU that controlls the engine performance. This is designed the be changed, since Mini comes out with updates frequently, and allows quick quick changes.

What the AccessPORT does is it saves the stock data, and overwrites it with our performance software to make more power. We spent weeks on our dyno perfecting these maps to make sure that they are safe and make a ton more power.

The Mini isn't too sensitive to intake changes, we have found that our normal stage 1 maps work great with just about every intake and catback exhaust on the market.

Before you go to the dealer, I recommend uninstalling the AccessPORT. If the ECU is updated at the dealer with the tune installed, the AccessPORT won't recognize the vehicle.

We haven't had any experience with this fix from Mini yet, so we're not 100% sure. If it's within the ECU that our tune controls, we will get it built into all of our tunes.

 

Thanks for the helpful response.

 

Nice to know that if the torque steer programming can be utilised in the Access Port it will.

Hope the UK/EU is around soon as looking at getting FMIC and JCW Turbo installed soon to add to the ITG Panel Filter and Milltek Turbo Back. Will need a remap then......

 

Nice!, Have you guys had any advances as far as the pop and burble development? Thanks

 

Still working on it, we will let everyone know when it's ready!

 

Had to go to the dealer recently and I uninstalled the AP. I noticed that with the stock map, the idle seemed more steady than with the stage 3 map. With the stage 3 map the idle rpm on my car tends to dip to about 600rpm them bob up to 800rpm while the stock map seemed to hold steady at about 700rpm. Is there anything in the custom tune that could cause this or is it just my imagination? It's not a big deal to me but if there's a way tune the map for a smoother idle, it might be worth making some minor tweaks.

 

ive noticed the same thing on my car with stage 3

 

Lasrguy, if you could log when the idle fluctuates like that, that would be helpful. After you do that, just email it to me, maps@altaperformance.com, thanks!

 

(As a customer )

I thought I had it straight, but now I'm not so sure. Apologies if this was earlier in the thread, which I did previously read in full before purchasing.

The HP performance graphs on Alta's site and the start of this whole thread are all labeled with the words "## Wheel HP gained." I was looking at these w/ interest across the stage 1 and stage 2 graphs, as well as the JCW vs. S graphs. But then when I looked carefully I saw the words "Fly Wheel Torque" and "Fly Wheel Power" above each graph. Now I'm not sure what Alta are measuring. Flywheel to me sounds like back of motor, and I'm guessing would be akin to bhp given the indicated stock numbers compared to what BMW/Mini spec. In the normal vocabulary, "wheel" to me isn't at the flywheel but rather downstream in the drivetrain with various of the frictional losses involved. In turn of course that is what a normal vehicle type dynamometer can measure directly.

Can the folks at Alta clarify? And if it was reported at flywheel as the graphs are at least labeled, what was the correction factor used from the road wheels (where presumably the measurements were taken) back to the motor?

Thanks.

 

And separate questions on Mini stock overboost for Alta:

What is happening to the stock Mini S and JCW overboost function in the Alta programming? Nuances of a given map aside, I'm guessing Alta generally ups things fort starters in general, and then limits them by reported engine operating parameters like various temperatures, knock sensor reading, etc. That understanding is what I took away from the Alta FAQ's. By contrast, I think the stock overboost function is regulated (at least) by a short term timer. And I'm guessing that short term timer would quickly be blown through in dyno testing too. But rather than speculate further, thought I would ask.

The question comes up again more broadly in reading the Alta performance graphs, where the simplistic ones Mini publishes for the JCW kit also include a line for the overboost performance function. Can you also describe how Alta did (or didn't) deal with overboost performance in the reported baseline stock Mini S and JCW performance graphs? Mini breaks that out into a separate performance line graphically, but again I think in stock form it is time limited.

Thanks again!

 

I've noticed the same thing with the stage 1 tune also.

 

I too have noticed, at random times, that when I pull into my driveway or a stoplight and stop....the idle will go up and down by about 200 RPM. Then will drive off and it won't happen again until another random stop. It wasn't enough to have me concerned but it is there.

 

Has Alta released names of other approved tuners that are tuning the Mini with the Cobb AP other than Jan at RMW?

It would be nice to see what other talented tuners could offer if they were able to use the Cobb AP.

 

Chris,
I sent a datalog of the fluctuating idle to the email address you provided.

 

I notice the fluctuating idle too.... 2010 JCW with stage 1 91 octane tune. It does it when my car is fully warmed up to operating temp.

Will there possibly be an update ?

Thanks

 

Mine too. 2010 Stage 3 91 oct.
