    That's what they said, and they appear to be very competent.....To quote Larry David "Having said that", we've seen similar promises made in the past which amounted to nothing. Fingers crossed because I for one am so tired of this damn 6AT.

    Stucks started a thread Nizpro cracked N54 6AT tcu? in N54
    Apparently it has been officially stated that Nizpro in Australia has finally cracked the 6AT tcu and will be able to flash them. If this is in fact true, i wonder what the future holds for us 6AT guys. I also wonder if the flashing will work with those of us who already have level 10 valve bodies and converters. Interesting and fun times ahead.

    haha, no doubt. and definitely. i only know of one way to do things. and its the right way. haha. But i'm taking a brief Pause on this which should total no more than 1-2 weeks max to complete an ECU project for another set of vehicles (non BMW). then i'll get back and finish this up. Because after that i need to complete the new upgraded XI trans case mount. Stay tuned though, will not be long. Thanks.

    A 70/30 water/coolant mix is going to reduce the BP to 104.4c and reduce corrosion protection (BMW actually think 40% G48 EG is the minimum) - that is kind of low. Are you thinking the gain is in the increased heat transfer properties - higher proportion of water ?

    Yeah I have that too and it drives me nuts. It's probably due to the rouge mounts since that's one thing we have in common (i got brand new motor mounts Reg Left IS Right). I thought it was a panel buzzing so i was looking for an offending panel and dampen it. Please let me know what you find tho,

    Our turbo kit only replaces that side. I will grab an IS mount for the drivers side and see what happens.

    You said difficult gear changes not un-smooth gear changes. The motor mounts cannot affect gear mesh, hence my comment. Swapping mounts is a quick thing to do, so you'll know soon enough. Hope you find the issue.

    That is strange that you only replaced/upgraded one side. It might be worth your time to just swap the other one out with a new one to rule that out.

    BMW coolant is G48. Coolants of the same standard would work fine. Liqui Moly coolant for example is G11 - the BMW water pump does not like that one.

    No, no other solenoid other than the OEM pierburgs will work. The OEM are highly specialized, "proportional" style valves, designed for vacuum only operation, and operate at 300Hz. The valve you linked is not proportional, is designed for positive pressure, and operates in the 15-40Hz range.

    Just flash the Dme to back to 98g0b and your Cobb device would be happy. If not - update the Cobb device then try again. For the n55 - the older roms seemed more aggressive from the way it burbles and accelerate ....

    Thanks, I totally agree. I just ordered some mounts. Hopefully will hey them in sometimes next week. I was just looking for some tips before I install. I will definitely report back and share my results. jyamona@motiv How old are your engine mounts? If they are bad enough, I'm pretty sure that you'd have bad vibrations ok decel like you describe.

    I'll take it back, stress on the linkage due to collapsed motor mount making the shifting clunky makes sense to me. Either way, doing motor mounts is much easier than opening up the tranny again. Do them first and see if the symptom remains. I would do it as preventative maintenance anyway.

    Edit, the first picture I saw looked like an aluminum body but when I look a bit more it seems like they are not. Either way, I would think that they would have to be of higher quality. The pierburg units feel so cheesy

    Have the typical signs of a bad solenoid. It's hard to justify the 200 dollars or so for a pair of oem solenoids when for a few dollars more I could buy something like this http://www.grimmspeed.com/electronic-boost-control-solenoid-3-port-mitsubishi-evo-8-9-10/ In theory, it should be a simple part and these should do the same thing, right? Anyone have any thoughts? They look to be made of billet aluminum and have MAC valves which are made for industrial use so they may be a bit more robust. Aside from modifying the harness and finding a good mounting solution, does it seem worthwhile?

    I should also mention that I sometimes have perfectly smooth shifting, even at high load because of the motor moving into a certain position. Once the motor moves, shifting goes back to a little less fluid. I'd also like to note that I'm not struggling to get into gears, it's just not normal like it should be. Why do you guys keep saying that bad gear selection is not a symptom? An incorrectly supported and/or misaligned motor will put stress on the linkage and make shifting sucky. That, along with clunky noise I'm getting post shift from the motor moving seems pretty evident to me.

    Unsmooth gear selection is a symptom of bad mounts for manual transmission car so I'm not really sure I understand why you're saying that. No I have no done that but I will when I do the mounts. I have experienced that as well. When I am at a stop and have the car in gear with the clutch depressed and rev the engine, there is not a clutch smell which is a sign of the clutch dragging. It's a spec 3+ with their smfw.

    Engine mounts shouldn't affect gear changes. With collapsed engine mounts, you'd feel vibrations even when you are not in gear and vibrations should be directly related to RPM. However, i do think it's a good idea to change engine mounts anyway. Even simply for the peace of mind that your PS pulley wont hit the subframe.
