    Can anyone figure out on what he did for solving the fueling problem?

    I would really like to know how he is fueling his turbos.

    He posted this on the other forum.

    Crazy guess-

    1. Reflashed fueling tables.
    2. In tank fuel pump.
    3. 4 nozzles of meth with some large tank.

    I would like to see what this means without the meth and how the fueling upgrade works there.

    Has he provided any results of the fuel upgrade on a non-single turbo N54? Or is this just something he is running on the single turbos.

    Yes that is what I want to know as will, plus I know on other platforms they are getting there HP on pump gas alone, before they even think about meth and the other stuff.

    Yep, that is my guess also. It might make sense to replace the OEM low pressure regulator with something that supports a higher pressure, and to use a booster pump that can be triggered on demand vs. an in tank. But overall I imagine these are very simple updates. Will be finding out for myself soon enough.

    Yeah and I think that would explain why you need to have him do the reflashing/tuning at his place. Unfortunately as far as a true fueling solution it doesnt mean anything for pump only guys... its an unfortunate shortcoming of DI.

    So you guys are all on the same page of a flash playing a major role in this?

    I think this was obvious to all flash tune owners 3-4 years ago. The rest were in denial.
    From all the things I've lost,
    I miss my mind the most!

    At the moment, a combination of the two (flash, piggy) is the only way to make things work... does it suck?? yes it does, do u want 600 whp? Then live with it or buy a different car (which would be my recommendation).

    Are you implying Shiv uses a flash in conjunction with the Procede on the single turbo cars? None of the customers have made allusion to such a thing, so far.

    From what I have heard from tuners addressing the DME in some way is going to be necessary so that this works properly. I think we need a lot more info but I'll go talk to people about this again and this time write it all down.

    None of the customers have said anything, and when asked they defer to Vishnu so clearly it was covered with them and they were asked to remain quiet about it.

    Is tuning the single turbo really so complicated that Shiv has to do it? I figured the reason he had to touch all the single turbo cars so far was because he had to do the flash work in person on them...

    You can call me a liar on an internet forum. I've read you say worse on other forums. But while you are doing that, I'll keep on developing comprehensive engine control systems for this platform. That being said, I've been developing a flash since last year for the MSD80/81 with the hopes of it being the "basic" engine control option for our single turbo system.

    So when I say what I say, i'm saying from personal experience based on actual testing. This means countless hours on the dyno, on the road and on the phone talking to many other flash tuning shops overseas. And as the only person who has experience with tuning single turbo N54s through both flash and Procede approaches, I'd like to think to my statements are justified. There are some advantages of MSD 80/81 ROM editing. Although perhaps not as many as you believe. But there are also many disadvantages as people are seeing with respect to just about every aspect of boost control, torque limit/actual deviation, and throttle reaction. And I'm not even talking about the obvious issues involved with rescaling load variables, integrating methanol control/monitoring and isolated boost control. We've done the work and learned the lessons. Others will do the same as their schedules/interests permit. Everyone who works with this DME knows how interdependent the tables/limits are and what compromises must be made to make things "work" on a basic level.
    So let's leave name-calling for kids. Because kids don't do what we are doing. Instead, kids like to call other peoples names on internet forums.
    Best Regards.
    Shiv
    He's flashing the dme for the single turbo cars. It's no secret he just doesn't talk about it. It would be hilarious if he's waiting for ATR to come out before releasing the single turbo kit to the general public.

    Why is he flashing when the Procede is so OMG amazing and does everything better than the DME supposedly?

    He took it back and said that he had been working on a basic flash since last year. But he emphasizes BASIC...

    It is not too difficult to get a piggy to do a basic flash as well. You can think of the stock parameters to be a kind of flash. It is not much different to flash another set of parameters than those "flashed" by BMW for the stock cars. Piggy works on top of the flashed parameters no matter if the flashed parameters were from BMW or from someone else.

    The easiest way to tune a car well is to flash part of the parameters and manage the other part by piggy. Both flash and piggy have their own strengths.

    Edit: As an example; flash by Cobb and meth + gauge hijackings by JB.

    yep, I agree best combo is piggy/flash. Just need some user flash tuning and we'll start getting some great combo maps. really the only flash tables that need altering are the fuel mass per load... other than that I'd have piggy do everything. depends on how the piggy is setup though and I hope Shiv starts optimizing piggy logic for stacking if/when he reveals a basic flash solution.

    And timing is best handled through the ECU. I say boost control and doohickeys/meth safety through piggyback.

    yeah if you're doing both then you're just adding complexity...if u dont need big single power, stick with a piggy solely... To me, it's really stupid to essentially introduce that many variables that you may later need to troubleshoot if you start to run into problems.

    Im running a piggy only right now. Seems ok until you really crank the boost. Then meth becomes a band aid.
