• Trouble in paradise? Vishnu/FFtec N54 335ii Single Turbo kits experiencing issues as a BimmerBoost member runs 12.5@121 with misfires and having to short shift

      BimmerBoost would like to thank member GeorgiaTech335Coupe for his openness and honesty regarding his Vishnu/FFTEC single turbo setup. Recently, this member took his single turbo upgraded 6-speed manual 335i to the PBIR (Palm Beach International Raceway) dragstrip in Florida to do some testing. His best run was a 12.50@121.6 alongside a 12.8@117. Yes, these times are quite a ways away from the 10.8@131 glory pass from Vishnu demonstrating the kits capability.


      This is in no way the fault of GeorgiaTech335Coupe who experienced misfires on his car and had to short shift at 6300 rpm in order to avoid them. Now, Vishnu has basically portrayed this kit as perfect and ready for sale with nobody having any issues. The reason BimmerBoost is bringing this issue to the attention of the community is for potential buyers to understand what they are getting into.


      There is absolutely nothing wrong with having issues when modifying a car to this level and BimmerBoost is confident Vishnu will resolve them. There is something wrong with pretending nothing is wrong. A few cars with the single turbo kits have gone up for sale and apparently a total of three people, that are willing to open their mouths, are having misfire issues with these kits.

      These issues will no doubt get resolved but potential buyers and current customers needs to be aware of the process, effort, and that progress is being made. Pretending nothing is wrong and collecting money simply is the wrong way to go about this and once again (it's becoming a trend) BimmerBoost is the only site bringing these issues to the attention of the community.

      For the record, a member by the name of @tmo335tt says he has a hardware solution for the misfires that he will likely share with Vishnu (hopefully not for free). Interesting that it isn't Vishnu but the community solving this.

      Thanks again to @GeorgiaTech335Coupe for sharing his details, good or bad, as we all learn thanks to honesty and openness. There is more to tuning than just collecting money.

        Misfire and knock detection are two different animals. Are you saying the knock factor table plays into the misfire detection sensitivity?
        I got banned on E90 for saying that lol

I've been unable to find any commonality that would explain why most cars don't and some cars do. But I think we are close to having this resolved one way or another. I appreciate the support from those who are actually looking to advance this platform.
        What the hell took so long for you to say this? So now only once it's out in the open and basically forced you decide to expand on it? It shouldn't take this.

        Has anyone stated why this is a 6MT only and not AT issue?

        The 6MT revs higher right? So are we narrowing this down to rpm dependent hardware?

        This would be so much easier if the thread wasn't filled with pages of guessing games.

        Sticky can you give Shiv 3 posts per day so he can expound on this and at least answer a few questions?

        i concur, i almost repped him.

        I hope he gets it sorted out. I would love for him to bring his car east to the ER event. I would love to see it stack up against legit fast cars

        you sound very familiar, and your approach is common. im willing to bet, again, that you DO NOT have a solution, and are merely attempting to quiet down was is obviously a growing trend, and publicity.. something a certain few wish to avoid. problem is, its public now.

        btw, gotta pic of your 2 cars side by side yet?

        cheers,

        You don't have a 335...why are you even in here? Go pound sand

        come back when you have some useful information...I'll share mine soon.

        i hear that a lot, funny it usually is said by those that have run out of legitimate comments to refute my statements..

        useful information? oh, you mean like i had that issue, fixed it, ran the car hard and did some notable things with it?

        id rather take your approach and say i have a fix, but im gonna not tell anyone..

        btw, got pics of said cars, side by side yet?

        You mean depending on which time zone he uses. Your timezone or mine doesn't matter.
