    I still don't understand the benefit to "on the fly" map switching?? I've never had the need or desire to instantly switch maps & in all hoensty, how many people with the JB4 have switched on the fly?


    Regardless which way you go, eventually you're going to need a flash to adjust fueling, timing advance & VANOS tables. Without a doubt, the COBB AP is the most convenient, user friendly & sensible flash solution (allowing for multiple maps to be stored on the AP & easily flash/code read/code clear) available for the N54.

    Not really talking about "on-the-fly" ... just to be able to change maps a bit quicker than with Cobb AP. It's a stupid thing anyway for me, because I'm using Stage 1 Aggressive with no other mods. Guess I just want to have a new toy!

    I only use map switching to turn off meth nowadays.

    Other things you might want a piggyback for:
    - meth integration (yes it is safer)
    - launch control/traction control
    - 2-step rev limiter (you can get this without a piggy)
    - overriding your gauges
    - flex fuel sensor (I know it's only on the procede and no one needs it, but I like the idea)

    Flash tuning seems to be the way of the future. I've got high hopes for RombinHood to provide some flash tuning competition to move the platform forward. (and I don't mind paying a little bit for his hard work Click here to enlarge)

    I think Vishnu see's a limited future for piggybacks. JB4/Procede offer a bunch of useful features for upgraded turbo's and meth, but a solid flash tune is the best starting point IMHO. I might take my JB4 out and move over to open source when it becomes available. Never felt the power has come on 100% smoothly with my ISO unit. Just want to see a few numbers and logs when the OTS OS maps are released. I'm pretty optimistic though.

    Does anyone know if BMS is going to support the Open Source platform? It would be cool if there was a way to upload their flash without buying a Cobb.I still like the idea of direct boost control over load based biasing. Maybe if there was a way just to control boost through the JB4 and have the flash do everything else, i'd be a happy camper. Is that possible?

    For those that are putting stock in the future of the open source project, not trying to be a pessimist, but i wouldn't hold your breath. At best, the open source will reveal the locations of tables - but that's only a very small part of the global picture. Things like on the fly map changes, load scaling for larger turbos that support of 2.5 bar etc will probably take years, if not EVER to become available.

    In terms of reality, the open source will hopefully create a more practical solution for piggy back users, that is more cost effective than buying a Cobb. Unless your blind and think Shiv is really trying to support the community in his efforts... He sees the future in terms of an at home flashing solution that doesn't involve Cobb.

    I don't want my question to get lost in the Shiv hate. Lol. Can you control boost independently with JB4 and have a flash tune do everything else?

    The short answer is Yes. The issue comes in terms of getting the JB4 and flash tune to work together, its a long discussion.

    Great Thread. Just signed into the site and this is the first thing I came across.
    I'm currently running Dinan stage 1 software but have been looking at all of these options for future, including Dinan stage 3...
    Glad to see all the different opinions without the petty drama. Glad I found this place.

    I'd say maybe 2-3x per month we get JB4 customers who run it on top of the Dinan flash tuning. Works pretty well now with the JB4 G5 ISO. When/if you get bored some day and decide to throw a JB4 in the mix just drop me a note for how to enter the settings. Click here to enlarge

    Repped, well outlined. I might add ease of tuning with boost targets instead of load, and change flex fuel sensor to simply ease of integration with e85, for both camps. Flex fuel sensor may not be needed but hey if you have the cash it's one more toy and a good diagnostic tool. Glad someone understands that difference.

    A few more days and hopefully much of the debate will be put to rest. I think that one thing that will come out of it with shiv so close to the project, is clear reasons to stack. Whether or not they are "needed" items or not, I have a feeling he's not going to undercut his own bread and butter. This translates well for jb4 users as well.

    Hi Terry.
    I just got the Dinan Stage 3 software installed and remembered this post.
    What can the JB4 G5 ISO get me in terms of performance?
    Does this fix the throttle lag issues as well?
    Thanks

    Well your best bet is to remove the Dinan software and run a JB4 with our free back end flash. But if you are stuck with Dinan you can use the JB4 on top of it along with map 2 to start. Similar torque but much better top end power. And all the JB4 features.
