    • 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.

        I think the achilees heel in this car is an ecu that is far too complex and finicky... if someone were to open their wallets and try out a standalone to run the turbo and all associated power components while retaining the stock ecu for traction and so forth; then we would probably be in a better position.

        The standalones that support direct injection are pretty expensive. The best bet would be to get something working with the stock ECU like undercover is trying to do with the proEFI.

        That, or you can always get an E46 M3 Click here to enlarge

        I think you should probably stick to comments on the N54 platform. This statement is so absurd I won't even justify it with a response on why it's so absurd.

        The only other cars that I could see myself in are the c63 and z06. C63 cant handle at all, I don't have enough hair on my chest for a Z06. Past that it would be a 911 turbo which is too expensive for me or just wait for the next m3 to be a year old.

        This is not an issue pertaining to the ST kit or the MSD80 or MDS81.....Since most of you guys like to talk smack and speculate then feel free to find the problem on your own. Per the majority request in doubting what I have found, I'll keep it to myself for now and focus on helping the other two guys that are in the same boat for now. After we have fixed those 3 then you will know 100% that the problem is solved.

Maybe you were just drunk last night or something, hope you come around and we all can get on to furthering this platform.
        Go find your solution elsewhere then.

        I'm not holding my breath unfortunately. In my time on this platform, if it can't be fixed quickly it will take a long time or never fixed.

        Took two years for shift bogging to be mostly fixed, two years for any work on 6AT timing flatline to be worked on, and hopefully not two years for this phantom misfire issue to be resolved.

        I am just happy all those HPFP issues from when this platform back in the early days was mostly resolved. Was the only thing preventing the N54 from being relatively reliable in stock form

        You have to understand that it wont affect us, because none of us have ST's, it only negatively affects Shiv, and FFTEC, and the entire ST platform that there is no solution.

        we are all just hoping you can get it fixed so we can see what the system can do.

        This isn't in anyway specific to Vishnu or FFtec and will continue to be an issue for any MT car making 500hp or more regardless of who made their turbo setup. This will happen with RB's, Vargas, ASR....and any others that are pushing a lot of power.

        Hey, keep in mind it still affects my car and I know of a few others that aren't ST...let's try to stay reasonable guys and stick to the facts..this is an "N54 platform" issue

        That is true, but my point was we just want to see your car's run properly. Its not hurting us as much as its hurting the users with the problem.
