My Byteronik ECU tune definitely has all three modes. And green still feels like green, that's for sure. And it still has the coast function. The question is whether it accesses the same map, but uses a different throttle sensitivity. I don't know.

 

I asked these questions when I was dyno-tuning my F56 at ByteTronik. According to Mike, the tuned map applies to all three modes. The only differentiation which makes each mode feels the same way is in transmission behavior and shift points (for automatic, manual is still up to you). I suspect the response in throttle sensitivity is differentiated by the way adaptations are picked up after the tune.

All 3 modes stay, tune applies to all 3 modes, but transmission shift points remain the same.

 

Thank you for the responses.

I figured all 3 had different settings, boost, timing air/fuel, etc. I never noticed this until my observant 11 year old son said, it sounds better in sport mode Dad. Then I noticed that it does have a throatier sound in sport.

 

All 3 modes are still intact as if there’s never been any modification to the ECU.

Green modes still slow and unresponsive, standard is now where the sport mode always wished it wanted to be, and sport mode is just on a whole ‘nother level.

 

This is a great topic for discussion because it involves us giving best guesses as to what we think happens. Of course it would be a lot simpler if the manufacturer (or a tuner) could answer a couple questions. I think all three driving modes access the exact same engine performance ECU map. The same timing, boost, fuel etc.Green feels so much different simply because most of it's throttle positions are way down the demand curve for power inputs, and you have to push the throttle nearly to the floor before the computer reads WOT (wide open throttle). In theory, as long as green eventually sends the same WOT signal, a dyno pull in green mode will be the same as sport. (Hint, hint to Byteronik at their next dyno tune...try it out)

It feels so punchy in sport because the first portion of throttle pedal movement sends a much steeper curve of throttle position input request to the ECU, but it's still the same map. I also get the feeling that the throatier engine growl sound in sport mode is 100% achieved by artificial sound the speaker system generates. Where green has very little artificial sound. But the shift points are definitely changed in the different modes.

Does our steering feel (assist) change? I haven't noticed.

Actually: I'm repeating a bunch of what yupetc already said. Sorry

 

The steering feel does change with higher driving speed, at least in the factory manual it does say that as I remember.

The suspension (if you have the electronic dampening option) does become stiffer in sport mode. And maybe, just maybe, it's a placebo effect, but when I'm driving in sport mode, the whole car just feels tight and stiff (I'm referring to both suspension and steering). I also want to ask, do you lots feel like the steering is a little too snug? as in the way the steering wheel is clocked with the rack/pinion and to the wheel knuckle? There's absolutely no play and no delay in steering control, and I'm having a hard time driving with such setup when I'm going up and down between 90-120mph on the free way. It feels like I need to do a lot more to keep it straight.

 

The ECU tune adjust maps that affects all 3 modes. Power delivery under each mode will react differently depending on the predetermined shift points specified by BMW under each mode.

Does this work for upgrading from a stage 1 to stage 2 tune?

 

Sorry, this is for Stage-1 or Stage-2 tunes only.

 

So, I uploaded my stage 1 tune to the car on Sunday morning.
Drove it to work this morning, And have to say I was underwhelmed.
My car doesn’t feel any different at all.
I had installed a boost gauge, for reference only, before I uploaded the tune, it sat between 6-8psi of boost, now it never gets above 5psi
Any thoughts?

 

Well it certainly doesn't sound right. My stock to stage 1 upgrade, you could not mistake that it was tuned and pulled harder. I only use the phone app for boost (now when my laptop isn't logging), not a gauge, but it shows it going up. Are you able to send logs to them. I ended up buying the Palmer software they suggested and put it on an old laptop, I then direct wired it to the OBD port so it had fast readings. Using the Palmer I was able to log the exact parameters they needed to look at. It took a little to figure out how to record the right logs, but it was kind of fun too. Good luck.

 

To start off, with an IC and intake, 6 to 8 psi sounds a bit low. With the Stage-1 tune, your car should be in the 15 to 16 PSI level (unless there are mechanical issues). Is your MINI registering any DTCs? Any boost leaks?

Hmm, it would definitely help to inform your tuner of the boost issue so they can help you figure this out. We sent you the tune back on March 2nd and received an email this Sunday requesting the stock map... but there was never any mention of your boost issues. lol.

 

Back in my R56 MCS, I have had an experience where I couldn't get extra boost after a tune, but at that time, I was replacing a turbo, and turns out that the wastegate was bad and the flap didn't get to close at all, yet it gave me 4psi at max. Looking at what you're describing here, could you have any boost leaks due to that boost gauge installation? Or did you do any mods right before loading up the tune? I've had very good experience with most tuners on NAM forum, ByteTronik did my F56 at their shop, met them in person, absolutely don't think they will leave you hanging like that. Just pm these guys and they'll square you away. You don't find that many good honest, anti-drama vendors out here in the modding world, ByteTronik is definitely a rare find; and they have so much technical expertise to offer.

 

Thanks to everyone for the advise.
I chose Bytetronik because of their reputation and attention to detail.
It was a thread on spark plug upgrades that sealed it for me!!
The car was boosting higher before the tune, if only by 2-3psi.
Now it gets to 5psi and holds steady there.
The guys at Bytetronik have been in touch and I am going to supply them with data logs so they can see if there is a specific issue, whether it be mechanical or electronic.

 

does this work on the F56 2020 ECU?

 

Sure. The ECU will still need to be sent off for bench patching regardless of where you get it tuned.

 

The 2020 Model uses the MG1 ECU. We are working on a solution at this time.

 

Cool looking forward to it.

 

Well, after sending a few logs in to the guys at Bytetronik and them using their wizardry with the map.... what a difference!!
My Mini now pulls like a rocket ship!! It puts on speed way faster than you realise as it’s so super smooth at delivering it.
Just first class service from them all the way.

 

Good to hear another strong result. I love my BT tune, really effortless passing others on the highway after the tune.
