    nothing hard in upgrading a SMG clutch, you can upgrade it like a Manual transmission.
    But i know nothing about the hydraulic pump.

    well, there are some questions such as:

    can we install a tripple plate clutch on a SMG?

    any modified SMG clutch will require a re-programming of SMG ECU.

    any tuners out there remapping SMG 3 software for upgraded clutch system?

    -I don't know, maybe. but certainly you need to tweak the pump for that.

    -G-power do that, but don't expect a good price.

    If i were you i would email G-power to see what they are saying, AFAK they are the only company which upgraded SMG III.

    You should have, it was great.

    No, it's a single clutch hydraulically operated sequential system.

    It would be like upgrading the clutch in a manual car, should not be a problem.

    There are tuners playing with the software but the amount of control they truly have is unknown.

    I would look to what HPF does with the SMG II in the E46 M3 to get an idea of what is possible with the SMG III.

    True, but they successfully upgrade the clutch.

    Thats right HPF use their stage 2 clutch on SMG 2 cars. I have personally installed them in HPF car and they are fine. No probs at all. I think you can safely upgrade the clutch to a stage 2 clutch but single plate. That should be good enough for an NA M5. The programming will be OEM clutch bite points and should work fine like the HPF cars.

    This is what I would think as well.

    This is the kind of tuner behavior that makes everyone so interested in doing thing themselves, like when open source software came out for Subarus and Mitsubishis. If you know stuff and want to keep it to yourself so as to make money off tunes, fine. I understand some people put a lot of time into decompiling factory data, and are loathe to give another tuner their data, since there are always those who will buy chip tuning hardware just to copy and sell others' hard work. But don't mock the end user or amateur who wants to do everything to their own car themselves. Some of us just want to know as much as we can about our hobbies and passion for modifying cars. I don't see how telling us about the various parameters of SMG software relating to clutches and what can be modified, could possibly affect your bottom line. Unless it is not about money, in which case I cannot imagine the motive for that type of post.

    I'm a little confused how Evolve fits into your stereotype? They have been extremely open with information regarding both software and hardware upgrades.

    If you take offence to somewhat cryptic responses, you could tear a strip off my back. I'm notorious for giving fragments that don't tell the whole story, but peak people's interest in a topic.

    Anyone can figure what's going on with any of these transmissions by spending under $1k on a good data logger. There are 5 or 6 signals that control what's going on, and once you see what they are doing, the picture gets a lot clearer. Trying to figure out how the transmission controller interacts with the rest of the vehicle is a bit more tricky.....I've seen code that actually changes the shift firmness based on steering angle.
