    ba114 started a thread Flash only anti-lag in N54
    Proceed at your own caution: i do not have as thorough testing capability as businesses. Note: Most of this credit goes to Terry of course. I had originally posted this in the anti-lag thread however it was removed as not officially supported by BMS/Jb4. Thought id post this here as i've been did a bit of limited testing with it prior to receiving my jb4 anti-lag kit. It worked just as utilising the brake pedal method used in beta testing for jb4 except rather than using the brake pedal to trigger, it utilises a momentary switch. I have since moved to the anti-lag kit to utilise the steering wheel controls ease of use. The hardware implementation is pretty straight forward however rudimentary. I wont duplicate the flash settings required for it to work here, for more information on how to customise the backend flash for this, visit: In order to make this work for flash only, it's a simple circuit connected to the IAT sensor wire and 12v. I used a posi-tap on pin 17, and ran the wire through the same feed hole in the DME area that you would run the JB4 USB cable through, terminating the 12v end at the cigarette lighter socket. remember to fuse the line between 12v and the switch accordingly (suggest 2.5A - 5A depending on wire gauge used). Pressing the switch will trigger a drop in IAT detected and will in correlation with load, retard timing.

    eric84405 started a thread Is my COBB obsolete? in N54
    I appear to be a bit slow to the party. I have a COBB V2 for my 2010 535. The car is stock, except for the Stage 1 Aggressive Tune . I also use is to check/clear codes on my car and the wife's 2012 X35d that runs a JBD. I know many are happy with the JB4 and it seems that Terry provides stellar support for it and is still adding features. I thought about trying a JB4 for the feature set alone and then along comes MHD with what appears to be a solid, growing following. Then there are people who are running the MHD flash and the JB4 being run together. Does anyone have experience with all three of these who can give me a brief rundown of pros/cons? Thanks!

    I'm throwing the car on the dyno on Thursday and I wanted to know which gear to dyno the car in. I know the 1.1 gear on our 6mt is 5th but I notice that everyone dynos in 4th. Is there a particular reason for this?

    Hey guys , Most of you guys know me from the e92 3-series section. I just wanted to share what I have planned for my X. The tires came in today so it is almost to fruition. Hopefully the wheels will be machined to fit soon . I can't wait to try out these Pirelli scorpion tires that have had awesome reviews.

    No the DME would bug out. Also IAT affects fueling a decent amount that's a good way to go super lean if it goes up instead of down.

    of course it does. Do you understand the concept of why BOV's are usually not a working solution for MAF equipped cars? Its because you are registering air that never making it to the cylinder, throwing fuel calculations off. At idle is a BOV closed or open? Closed, all air entering the motor is accounted for. This car is a DCT it does not close throttle during shifts, meaning its not blowing off any air that is accounted for. The only time is blowing air is when you lift after building boost, at the point the dme has already completely leaned out the AFR, and thrown in a bunch of timing for fuel milage, etc. The BOV works as it should. If you have an MT and are worried about losing calculated air during a shift, we simply use a Tial QR, and recird the air back in to the inlet. Gets rid of the shitty ass DV system, and keeps your MAF calculated values happy. Nothing new here

    Weehe replied to a thread N55: VTT N55 Stage 2 testing 524WHP in N55 and N52
    So you added a BOV to a car with a MAF, made no tuning changes, and it idles and runs perfectly fine?

    "Back in December, we showed you Don Groff’s unique home-engineered twin-turbo V12 project he’s building up from a pair of Toyota 1JZ engine blocks, and we recently heard from Don with some updates on how the project is progressing along. Originally, the plan was to use four turbochargers as you’ll see in the initial article linked above, but Groff has since changed the plan to use a pair of Garrett turbochargers that will support 550 horsepower each. “I mated the engine to the transaxle and started the process of how to package everything that needs to be located. I think I have a plan and made some PVC frame rails to help visualize where they need to route. Also, there is a new linkage mechanism so the six-speed can be shifted from up front with a pair of Morse push-pull cables,” says Groff. " Read more at

    Forgive me for not reading the article on N54 tech, but in theory, could all power be disabled from the IAT sensor through a more simple switch? In most vehicles, this causes a sensor to read max one way or another...unless the DME stops using the IAT table all together.

    All of the above can be fixed in the flash with a few more tables. I just need some time to define them (currently making the XDF's 100% accurate in scaling, min/max val, etc). If someone wanted to make me one of these circuits connected to a simple button for testing purposes, that would be great too, and would re-order my priorities a bit =)
