Ever feel like car looses too much traction with the tune?

I drive very rough and 99/100 of times I'll be able to control the car when it looses traction. However, those 1/100 times can be the difference between a nice car and a big paperweight

proTUNING Freaks responded to a similar set of questions within 24 hours, though they've been slightly less quick at responding to follow up questions. Other BM3 users reponded to PMs very quickly though, so I went that route.

I'm sure that VF's solution is good, but the thing that killed it for me was the fact that I got no response from ANYONE on if Start / Stop was disabled with the Hex tunes. BM3 also doesn't prevent Start / Stop from working, and so far at least, hasn't given me any carbon deposits... I might check again though, it's probably too early to say for sure on that one.
Interestingly, my start/stop is disabled after the tune.

I think the traction control in stock form is WAY too aggressive and intrusive, and I really like the way it is now, other than it still being too restrictive in 1st gear (almost impossible to get hard acceleration in 1st, since day one). Sometimes I miss my tuned S6 for the awesome launches it was capable of. I do enjoy being able to slide the rear around a bit with the throttle with this car now, though.

Code in M4 GTS EuroMDM and then it's a huge difference. I can spin through 1st and 2nd.

How do you go about coding in the M4 GTS EuroMDM?

I just installed stage 2 last week and also notice that Sport Plus is way too intrusive to have any fun. I've been using DSC fully off most of the time and I've noticed the throttle response is very sluggish in that mode. Is there a way to improve throttle response in the DSC off mode?

I'd like to know the answer to this too. I coded the M2 Euro MDM, and that's better than US, but it's still a little restrictive.

Another topic maybe, but I'd also like it if my tune set the behaviour of Sport+ to be exactly the same as Sport, but with MDM mode for the DSC. You get used to the Sport throttle response and steering, and full DSC off is an option, but as it is by default, if you want to use MDM, you have to choose between comfort mode response (traction mode), or over sharpened throttle response (Sport+ mode).

Almost all M2's produced should have that option in there. Use Esys or bimmercode expert and look inside the DSC module. Gonna upset some coders in here but yeah....

Code:
3000 DSC_CODIERDATEN_ALLGEMEIN (DSC CODING DATA GENERAL), 20 

C_Variante_Fahrzeug_e (C variant vehicles)
F87 = 08

Comment = 

OPTIONS
  F80 = 00
  F82 = 01
  F83 = 02
  F87 = 08
  F80_CP = 03
  F82_CP = 04
  F83_CP = 05
  F82_GTS = 06
  F80_CRT = 07
As for throttle response that's all in the tune. Send me a PM Nezil

So what do we have to put in to get sport&mdm on the sport+ setting? The sport+ pedal sensitivity is way too sensitive

Just wanted to give some Stage 2 feedback regarding cruising - not sure if there is any concern out there about this, but here's what I just experienced:

Mods:
- CSF Intercooler (Black)
- Fabspeed Sport Cat
- VRSF Charge Pipe

Weather
- mid to upper 80s (F)
- mid-range humidity
- 700-800 sea level

Settings
- AC on about 25% of the trip, windows up always
- Comfort mode the whole way

Stats:
- 190 miles
- Average speed 68.5mph (in a 70mph zone mostly)
- 27.4 mpg

This mpg was better than I expected and I was well pleased!

I believe that I am starting to feel some misfires at full throttle - not every time however. I am starting to wonder how I diagnose. After testing it out again during a track day in two days, I am thinking of going back to the stock tune to see if it happens then - and if so, I will roll some dice and take it to the dealer. Thoughts from the smart people reading this thread...? I have 7,300 miles and always run the same 93 octane fuel - perhaps I should wait a tank before updating the tune which I will take care of during my next track event...?

7,300 miles seems early for plugs, but this is my first BMW. It'd be disappointing if that's what's wrong. Not sure if I should take it to the dealer for that or just do it myself because of the warranty situation. Would a tune cause the plugs to go bad this soon? If so, then I'll do it. If not, then I'll bring it to the dealer.

O2 sensors

I added Stage 2 Hex tune this week. Bolts-ons are Dinan intercooler, FTP charge and boost pipes, Fabspeed sport cat, and AFE ProDry filter.
Seat of the pants improvement is very impressive and I'm happy so far but not 100% blown away as there some mild surging at light throttle. Nothing I can't live with though.

I was setting up data logging in Torque Pro to see if I could spot this and noticed that now only one 02 sensor is showing up as available (bank 1, sensor 2). Is this a function of the tune? Or could a sensor not have been reconnected when the cat was changed? Is 1x2 the cat in or cat out sensor, and should bank 1 sensor 1 be the other one available? If a sensor is disconnected, does it just disappear from the list available via scan?

That's either an issue with the data logging software you're
using, or possible installation error from the exhaust system.

All factory functions will remain intact with our software as the
O2 sensors serve multiple tasks aside from emissions functions.

Just recently started to log on Torque and I am stock and I think it just showed O2 Sensor1 for me as far as logging.

Maybe it's an issue with a Torque update... I'm pretty sure I've seen both sensors some time in the past.

So far, it seems that it was a bad tank of gas from a gas station that I don't normally go to (it was out of town where I am guessing people don't normally pay for 93 octane). It took what seemed to be two full tanks to go away. HEX was very helpful throughout, by sending me their thoughts and helping (via direct mail) - I am very pleased with them in this regard!

Can you please clarify what "is now backfiring" is or sounds like? What differentiates it from "burbles?"

I'd like to help brooke1972, but he's notorious for posts criticising tunes, usually promoting Hex, and being negative about others, but I'm not not sure if we should be taking him seriously or not.

I'd suggest getting some logs first to see what's going on. I realise that the Hex platform doesn't support this natively, but if brooke1972 has MHD, that does doesn't it? Otherwise Torque Pro had some logging capability.

No one else is having similar problems with Hex, based solely on the brief description alone, so I think logging is the only way to get more info at this point.

8,000 Miles on My M2 Hex Tune.

I call BS on "backfires".

Both have been flawless.
