    Alpina DSC Flash - is it any different and is it possible?

    Just wanted to start a discussion the the Alpina B3 DSC software. One thing I have always been disappointed with on the 335i is how intrusive the DSC system is. So was thinking about it and about how much better the Alpina trans flash is and started wondering if Alpina tinkered with the DSC programming.

    So the questions are:

    1. Does anyone know if the Alpina DSC software is different and if it is if anyone has experienced it?
    2. If so, then what is the alpina ZB number for the software?
    3. Can it be written onto our cars?

    The DSC90 folder in the V48.1 Daten seems to contain the files for the DSC module. Unfortunately, the files do not contain headers like the GKE215 (6AT) files that might give an indication of what the file is for. For instance with the 0DA file programmed to my US 6AT, you can clearly see from the headers the file is for a US vehicle. The Aplina file is clearly for an ECE vehicle (Europe). You can then link the 0DA files back to 0PA files using the GKE215.dat file.

    You would need an Alpina B3 owner to read the car's modules with INPA, then we could identify the ZUSB number and/or the 0PA file used.

    Why don't you just hit the TC button once and go to DTC mode?

    Just want to point out if anyone could correctly alter this software it would be Alpina.

    It would be nice to have a traction control that actually lets you push to the limits of traction and not like a typical GM style nanny that cuts all fun at the first sign of an issue. Smoking the tires doesn't put power down to the ground and neither does suddenly cutting 60% of the power. I've owned several NA cars like this, my Acura TL I could floor it in the rain and sometimes it was so quick I wouldn't even spin at all. It never had a hiccup or noticeable sudden cut of power it just felt a little slower than it should have been.

    I do hit dtc a fair bit, but I would actually like the standard mode with stability control to allow a bit more fun while maintaining stability control, thinking this is what I would allow if I was alpina, kinda like the m3 does, allowing fun but saving my ass when needed!

    dtc is ok, but still a little intrusive and not progressive, it is still a bit like a light switch when it comes on, the m3 is much more progressive as it comes on.

    I have not found any specific reference to what alpina does to dsc, but lots of Internet chatter about how it is different and more progressive and allows a bit more fun.

    A little known fact is that ALPINA work on the DSC settings as well as engine management stuff. Specifically, they have extra settings that sense when the car is being driven "progressively" such that the DSC will allow more slippage than the BMW system before intervening. It isn't a huge difference bu allows a driver to lean the car more enthusiastically through the twsity bits and allow for the tail to slip a bit more than usual.

    It's nice to have a close relationship with BMW. Too bad Alpina doesn't use it to build monsters.

    I can't imagine how much fun could be had having access to all of BMW's source code and being able to build whatever you wanted!

    They certainly seemed to go a bit further with the new B3 than they had on the previous version!

    Twin turbo N55? No problemo. You want to upgrade N63 turbos? No problemo.

    A shame BMW is such a $#@!.

    It must be a bit frustrating at Alpina with all that access and info and then BMW legal probably has a book a foot thick with all the rules they can't break so as not to compete too much with BMW products etc. Such a shame.

    Well the new B3 (F body) has electronic dampers so they must have seriously hacked the DSC to get all those acronyms to talk to each other. I do not believe this was available on e90 B3.

    The suspension set-up of the new B3 Bi-Turbo provides excellent ride-quality and comfort while simultaneously offering sharp and dynamic handling. The adaptive ALPINA sport suspension solves this conflict of interest by means of electronically adjustable dampers in collaboration with performance springs, bump stops and stabilisers. The system allows the driver to use the Drive Performance Control (Eco Pro, Comfort, Sport, Sport+) to select the suspension setting and driving dynamics to match his mood.

    Certainly way different from the relationship of Porsche and RUF, which Porsche pretty much lets them do as they please.

    Porsche is way more enthusiast geared than BMW that is for damn sure. RUF has done some pretty cool things.

    With certain cars they do. They have a lot of leeway.

    Hi man. The DSC Flash from Alpina is same! But they have different coding in version b3sGT. b3sGT have StopTech brake system front 355/32 rear 345/28 and this data must be a coding in DSC90 pump ECU.
    Thank you.

    Is there also a difference between the B3, the B3S and the B3 GT3 with the AT flash?

    I drive the car pretty aggressively in DTC mode and don't find it intervening much at all. The DSC mode is horrible. Why wouldn't you just go DTC again? I read the comment, but I don't get it. What do you want that the DTC mode doesn't provide? More or less intervention?

    I thought they made some improvements over the B3 since 2007, especially with the B3 GT3 (2012), which is meant for track use...

    Less intervention, more the the M mode on the M3 where it will let it get more sideways before cutting in and a more progressive intervention would be nice instead of making it feel like you hit a wall!

    Very strange. I haven't experienced this hitting a wall thing you talk about (with DSC off). I definitely get it sideways too, but not at very high angles. Actually I dont think DTC mode limits your lateral movement. I think it just reduced wheel spin to maximize traction using brakes where as DSC clearly downs the throttle/timing. Why wouldn't you just turn it all off if you're concern is a high slip angle and wanting to spin wheels? I guess I just don't see a very big difference between DTC and all off unless you're trying to get more wheel spin or less intervention over a bumpy curve which would have wheels spin for instance.
