    • 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.

        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.
        It's always been a problem of "Red Herrings" that lead you off on tangents. But with the "flatline fix" I think we're finally making solid progress. The first step was accepting it was an actual mapping issue and not just knock. It took me 2 years to get to that point. Click here to enlarge Then I realized it was coming up more frequently on the ISO firmware which pointed me towards the analysis that led to this potential fix. Anyway I'm hoping for the best on it. As I told Chuck I've been fooled before so until we get a few previously "flatlining" cars out doing 1/4 mile pulls with the new firmware we won't know for sure. At the very least we're on the right track.

        On the manual trans misfires, in my experience it's different every time. We have a few manual cars putting out 500-520rw without reporting any misfire codes so I'd be surprised if there was some inherent hardware issue that affects all manual transmission cars in that power range. Beyond that power level I have not personally explored much so I'll defer to those who have. I do understand the mechanics and electronics of the N54 very well so if anyone wants to throw a theory out I'd be happy to give it a thumbs up or thumbs down.

        This is nothing but a hobby to me. I have no business in this market and don't plan to make a dime. Everyone has been skeptical so I don't want to "jump the gun" here. Be patient.

        As a matter of fact I help people out a lot for nothing in return. One guy just emailed me and has a blown DME, he is coming to my house to have me fix it and I don't expect anything in return. All that I get is the satisfaction that the dealer didn't get to take another person for a couple thousand bucks when it can be solved for less than $5.

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.
        Doesn't really give anyone much confidence in you. Kind of immature behavior.

        Or at least something basic regarding the central idea here?

        Why not the AT's?

        Wow, I didn't think there was another person who thought like me. If my turbos take a $#@!, then I will try to CPO it and enjoy my bolt ons again. If it gets denied, then I will consider RB's but definitely won't go past that as it would be a better idea to look into a different platform for more power (Z06 in my case).

        If this guy really did have a solution to the problem, he would have shared it..what reason would there be to keep it to yourself? Its not like hes going to make any real money off of it, and he did say hes not in it for the money, so why hold back?

        My guess is this guy doesnt have any solution to the problem, and just wants to feel special or something, who knows..

        And if he did have an answer or atleast an idea of what the problem could be, and still decided not to explain himself, then sorry but this guy is just being a drama queen, its really not that serious..dude is acting like he has nuclear missle launch codes

        God damn this forum is ridiculous. As he said when the solution is totally tested and works he'll explain what the deal is. Until then I'm getting the biggest kick out of you guys complaining, it's awesome.

        its not a matter of complaining, I dont even have a 335 anymore so it doesnt affect me at all..but its just funny to me all the drama you guys try to create acting like you have secret to cure cancer

        Well, definitely much more noble than saving Vishnu.

        Regardless, perhaps you opened a bit of a can of worms by saying you for sure have a fix yadda yadda but then saying nothing about the actual fix if it exists. You can't blame people for asking you to expand on your own claim.

        Like I said, if this is the piss poor attitude youre going to take, I would rather wait and find a solution elsewhere. No one is going to bend over, palms to the floor, and take your drama. This is a forum for the future development of the platform and for the communities benefit. The entire purpose of a forum is to share knowledge. You cant complain anyone is a "computer jockey" but yourself if you're going to come into a forum, announce you have a solution to the problem, then not share it. Google forum troll.

        Seems to me that tmo335tt feels confident he has a solution but doesn't want to release it until he has a chance to test it out and verify it works. Makes sense to me. If it doesn't work, I'm sure he'd advise everyone what he thought it was.

        The amount of $#@!ing, whining and complaining on these N54 forums is unbelievable.

        exactly..some people are getting a little defensive which leads me to believe Im on to something, but Ill bow out of this conversation and watch from the sidelines..

        Theres an old saying "two heads are better than one". If this guy really does have atleast an idea of what the problem is, then the best bet to further the N54 platform is to share the idea with people who might be able to expand on the idea, and really find a solution to the problem. I think its a pretty safe bet that this problem would be fixed alot faster if more than one person was working on fixing it, instead of just one guy saying he knows whats wrong, but doesnt explain what it is..sounds pretty selfish to me
