    Is there a practical solution to the IJEOS timing flatline (flash only)?

    The Alpina flash is all well and good, but timing into 4th is still dropping far too often in almost all IJEOS logs I see. If need be I could stack with a PROcede or JB, but i'd rather not. Is there a proven flash only solution?

    I could buy MSD-80 I guess Click here to enlarge

    #1 . You cannot throw an MSD80 into a late model N54.
    #2 . Unless Cobb has TCU access, you won't fix the flatlining flash only. You can improve it but still not as good as the flash/piggy combo.

    Unfortunately, "working on it" is where it's at right now.

    Ugh. That's what I was afraid of. I was talking to Enrita a bit about an MSD-80 swap, @themyst when you say "late model" do you mean any msd-81 factory car?

    I would really prefer to leave everything to the DME on flashed tables....losing cyl 2-6 for logging would be extremely frustrating. Stupid 6AT.

    I really want to avoid a tuner war here, but for various reasons I really don't want to stray from flashing to the DME. I'll live with it for the HFS-4, but outside of that i'd rather remain flash only.

    Problem is if there isn't a serious solution, I don't really have a choice do I? In that case i'd probably give in and get a used PROcede, but then i'd have wasted a bunch of money on the Aquamist setup when I should have gotten Shiv's hardware. Click here to enlarge

    This shouldn't be anywhere close a tuner war. You have two options:

    1) Stack a JB and stop the flatline.
    2) Stay on COBB and live with it for now.

    You say you don't want to stray away from flashing the DME, but stacking involves doing so. Also, I'd stay away from anything Shiv spits out.

    Well yes stacking of course still leaves the flash in control of a lot, i'm just not thrilled with the prospect of logging using a single cylinder for corrections. Ideally of course, I have no interest in stacking. But the choices seem very limited, and very clear.

    I don't get into the whole Shiv vs Terry stuff, but i'd be perfectly open to either tune. How does the JB integrate with Aquamist?

    JB running isolated boost with the flash doing everything else is fast, i'm not denying that.

    I'm with you in not giving up the ability to see your motor's timing. Cylinder 1 tells you nothing. This is why I'm not stacking on my car. I do prefer the control the JB has over the wastegates in comparison to the way the DME controls boost but I can't lose logging values as essential as timing.

    I'm not aware of the integration Aquamist kits have with the JB. @Terry@BMS?

    Yes, I've been done with that forum for awhile. Jason gave me two infractions over some complete bull$#@!, and I'm not going to be playing games with that fool wasting my time. If he wants to hide facts to increase his profits I won't be there.

    The JB4 integrates nicely with the Aquamist kit. Better than a flash only tune ever could. Click here to enlarge

    No cyl 2-6 timing logging yet, though, but its being worked on.

    I would stack with a JB in a heartbeat for meth integration and direct boost control....if we could see what all cylinders were doing. Terry if you can pull this one out, it would be 110% awesome. And yea I couldn't agree more, the JB ingrates with meth far better than any flash can. Though I trust the AM failsafe on its own.

    FWIW, the backend flash isn't a "fix." It reduces the effect but it is still there. It sucks that there really isn't a solution yet.

    You can't put an MSD80 into a car that comes with MSD81 from the factory.

    I would "prefer" to be flash only as well, but the JB4/Cobb Stack works fantastic. Terry@BMS did some dyno testing on how much the flatline costs you in terms of power.

    why cant you log timing on cyl1-6 with your Cobb when stacking? Does the jb4 "take over" the can bus?

    Yea JB highjacks the CANbus. You lose a lot on the logging side.

    Could you get cyl 1-6 logging available for those who run the Cobb back end flash? From what i hear the issue is that not all ROM versions support cyl 1-6, but we already know Cobb fix's that. I'd honestly probably pick up a JB4 in the future if you got that feature enabled.

    If there was a practical way to have a piggyback control boost while having the DME handle everything else + full cylinder correction data logging, I’d stack in a heartbeat. Dialing in boost curves flash only is a pain, but it’s more or less a deal breaker to only see cyl 1 when logging for me.

    That is almost precisely what the stack does. Does a little bias but if your trims check out then the JB4 serves as a de facto boost controller.

    If you're running stock turbos cyl 2-6 is more or less irrelevant. If running RB turbos it's good data to have but the curves we run are well proven over the years so IMHO not a deal breaker. For large single turbos, I really want to get 2-6 working...

    You know orders of magnitude more than I do about this platform, but i'm not willing to concede that going blind on cyl 2-6 is irrelevant, or close to.

    I get your broader point though. You guys have dialed in 1,000s of cars, i'm not suggesting anything is going to explode Click here to enlarge

    Stacking is an increasingly appealing option.
