    A 30/70 or 20/80 split F/R would be fun to play with. Do the XI differentials actually lock though?

    Dan,

    I'm not aware of any development we're doing on driveline management at this time.

    Thanks,

    Gary

    BASELINE,

    We're seeking cars to test this no. So far we've been having difficulty getting access to these cars in Austin. If you know of anyone, please send them our way.

    Thanks,

    As far as I know, the xDrive cars from 2006 on continuously vary torque split and can send up to 100% of available torque to either axle. My complaint is that when I roll on throttle while cornering, the car understeers so severely that the first time I got on it hard on a freeway ramp I thought I was going to go over the high side! (Turns out it detects the understeer and corrects, probably with a combination of brake application and reduction of front torque.) Wouldn't it be nice to start with 90-100% rear and feed torque to the front as much as possible while maintaining neutral balance?
    More available torque will only make me wish harder for a modded torque split map!

    You're reading my mind on the torque split thing! And yes, 6 kids. One wife. Really.

    SlicktopTTZ,

    Our headquarters is in Austin, TX. That's where our AccessPORT engineering, performance part engineering, R&D, customer service and warehouse is located. We also have retail sales and auto service colocated with them there. We have three other retail sales and service facilities in Plano, TX (COBB Tuning Plano), Portland, OR (COBB Tuning Surgeline) and Fountain Valley, CA, which is in the LA area (COBB Tuning SoCal). All of these facilities contribute to R&D as well.

    The main R&D tuners we have working on the BMW AccessPORT is Lance Lucas in Austin, TX (who works alongside Rob Irish, our BMW ECU Guru) and Tim Bailey up in Portland, OR. But it would be most convenient and efficient to have an IS and 1M be in the Austin area.

    Thanks,

    Gary

    I'm looking into getting into a 1M as soon as possible, and I've considered moving up to Austin to either expand my HVAC career or get deeper into my passion for performance automobiles.

    It really is a hard decision as I am 20 years old and can continue to further my father's HVAC business, or do something I truly love to do, modify internal combustion engines and sport vehicles. I would likely not even consider it work. I've even looked at positions at Boost Logic, but I don't really know where to start.

    I have a background in light IT work, building science/thermal management, HVAC system engineering and data entry. I work on my vehicles in my spare time, and have done great amounts of research on my own in order to improve my knowledge of the automobile world. Given the data, I can work out most engine related formulas, and picked up how to plot an engine onto a compressor map for turbo selection.

    I'm just curious, could Cobb ever use a person like me? What would you recommend me to do to get into the field? I would love to do work like you guys, AMS and Boost Logic do.

    I work a lot with computer software and could most likely pick up computer modeling and fluid dynamics software fairly quick.

    Or maybe one day I will have a nice AWD dyno of my own down here in Corpus Christi, next to our business, AC Distribution. With proper training, would it ever be possible for me to be part of the authorized Cobb dealer/tuner network?

    Anyway, thanks for coming into the N54 market, we appreciate your work and dedication to improving your product.


    Sincerely,

    Chris Mundahl

    mucho respecto!

    does anybody realize the possibilities this product opens up?!?!?! you all should be STOKED! custom kits, custom tuning, custom engine builds, multiple maps, etc...

    We are all stoked, but is there still the issue of the 17 psi or so limit with the flash tune? If so, what good will it do for those wanting to run custom turbos with more boost?

    Ahhh. I was not aware of this limitation. Interesting.

    Well stage 1 is piece of cake and there are lots of them out . The real challenge is stage 2 upwards.
    By the way the limit is at 14.5 psi . after that you need to rewrite all new boost tables . so there is no limit (well is 22psi because of the TMAP Sensor) when you have passed the factory ECU limit.

    I would think they just flash the limit away. It was said first that flashes have a limit of 14.5 psi. There is always a way to lift the limits in tuning.

    Exactly and if you upgrade the TMap sensor, you can probably lift the 22psi limit as well.

    yeah but i doubt you can run more than 22psi on stock internals safely without lowering compression , adding fueling and running race gas / meth.

    Of course, but this is more just future discussion on how the Cobb could be used for people who have custom built motor setups.

    My AP arrived and, as I expected, the xi is not yet supported. ECU data is on it's way to Cobb.
    Gary,
    Any guesses for when xi support will be released?
    Thx,
    Dan

    The AccessPORT should install on your Canadian model without issue. We are nearly complete with our XI testing and should be announcing XI support very soon.

    Thanks,

    We just saw a vid of an xi accessport car running so how could it not be supported?

    The AP readout said it was identifying vehicle, then said it wasn't supported, and then offered to record ECU data.

    How does this tune read performance numbers?
    Does it have built in GPS? Accelerometers? How acurate is the data it puts out?

    That's weird, so which year xi's are supported?
