    Hey guys, Spent a couple hours on the dyno today with our 2012 335is DCT development car. The car is 100% stock except for a dual cone intake. The car is running 91 octane fuel with no octane booster or E85 mixed in. Otherwise known as the worst gas you can tune for. All runs done in 5th gear. Temps in the 70s. First up was testing on the stock tuning for a baseline. The JB4 was installed by in "flash only" mode for logging purposes only. e.g. white subconnector left stock and JB4 on mode 4/4 so it can't influence the tuning at all. I was surprised by how choppy the timing was on the factory tuning. That's 91 octane fuel for you. I've seen the 335is factory tune go anywhere from 315whp to 335whp on 93 octane so we're at least in the ballpark here. Since the car was in "flash only" mode I decided to give the MHD v6 Stage1 ACN map a whirl. We frequently test competitive maps to ensure our customers are getting the best product available. In this case the off the shelf flash map was disappointing. We work with MHD on back end flash stuff and always look to maintain a positive relationship so I'll leave it at I think this specific map needs more work. Next up I flashed it back to stock, reinstalled the JB4 in full control mode, and grabbed a few runs on JB4 map2 and map5. I failed to capture one in JB4 only map1 although as I'm writing this I wish I had. Results were about as expected. Good power across the board with timing drops fairly similar to the stock mapping. If I had taken the time to do more runs on map5 I suspect it would have detuned itself a bit. Finally I loaded up the ina0s PUMP back end flash map and did a couple runs on JB4 map1. After these runs I spent another hour working on ina0s BEF improvements but I'm not quite ready to share info on that yet. But as a cliff notes I was able to get timing a little more stable and fix the torque limiter causing timing to go negative at 3000rpm. Still, these runs/logs on the currently available map provides a good indicator of where the JB4+BEF 91 octane DCT tuning is currently.

    Hey guys, It seems that there are more and more reports on rod bearing failures so I am starting this thread to understand which factors correlate the most to failures of rod bearings in N54s. As our engines age, this may be an impending issue if we don't address it. I am hoping to collect data to find the common factors to this issue which will help us prevent it. The most obvious factor is oil dilution. Please read this if you want to know more: https://www.amsoil.com/techservicesbulletin/MotorOil/TSB%20MO%202004-07-02%20Fuel%20Dilution.pdf So for those of you who had rod bearing failures please answer the following questions: Which N54 car do you drive (Model and Transmission) Miles on the car/engine when the rod bearing failure was detected What HP/TQ were you running when you detected a rod bearing failure (Name the modifications if you don't know.) How many miles were you running the previously stated setup What tune / who tuned Did you have leaky injectors What fuel did you run Did you often turn the car off before it reached operating temperature (short trips) Did you idle the car a lot What is your OCI (Oil Change Interval) What kind of oil and viscosity do you use External factors (e.x. Shop forgot to put oil back) Much Appreciated!

    Both cars are stock! Pretty impressive for the M2 even at high speeds. I think a simple drop-in filter would do wonders :awesome:

    Not going to get into this as I have for over a year on the subject. First off, vacuum as we all know is ideal in the crankcase in all situations, if possible. The VTA solution is never providing this PERIOD. You are essentially creating an exit hole for the pressure to escape but not actually drawing it out through vacuum. Although the above setup will "work" its not ideal. I have tried every type of PCV setup (including the AD fittings) on this platform and the RB design was the only one that actually showed positive results in all fields. It draws vacuum at idle/low load which is then routed through a high particle OCC, I use a Mishimoto, then routes back into the intake tract. This is the best case setup as you are retaining vacuum, but you are also adding an OCC to separate the oil from the vapor which was not possible at all before. As a precaution as well, I have the ports in the head blocked off to prevent unnecessary boost pressure into the valve cover. The BMS OCC only works under load and boost where the check valve closes and vents through the flapper valve. On this side, I am running the flapper off the valve cover WHICH IS NEEDED to properly regulate vacuum in the crankcase. There is an orifice in the flapper which takes on this task. If you run a full VTA setup as Jake does, then the flapper is not necessary as there is never a situation where vacuum is being drawn into the crankcase and at that point, it will just be a further restriction. If you choose to go VTA, go with the largest size hosing possible with the least restriction. From the flapper, I have a 1in line going to my BMS OCC and from there I initially had it routed to my intake on my turbo. This was working fine but it was making my filter filthy and oil was getting everywhere in and on the outside of the turbo and surrounding area. Since then, I have just going VTA on the flapper side after the BMS OCC with no ill effects. This went longer than I wanted it to but in conclusion, I know that the RB PCV setup is currently the best setup. It single handedly stopped my oil consumption issue which was caused by excessive crankcase pressure. Oil was not properly draining from my stock turbos which is why I chose to go single turbo. Low and behold, I went through 2 brand new single turbos to still have oil being pushed though the seal and burn. This is when I knew there was an underlying issue. When I considered my engine's wear/age, I thought about possibly having more crankcase pressure due to worn piston rings or who knows what not allowing my engine to lubricate and drain properly. This setup relieved the pressure and allowed my oil to drain properly finally putting a stop to my smoking problem. This is how I know this setup works....

    V8Bait replied to a thread 335is 91 octane dyno testing in N54
    I'm gonna have to echo Martial, a stock car on 91 octane should be right around the 335is factory levels, maybe a touch higher, made more consistent without the overboost. Too much more on 91 when you're totally stock leads to some ugly logs after a gear or so. I don't like to go over 350whp on 93 even, it's not that much better than 91, and once the heat sets in logs get just as ugly. FMIC is such a necessary mod for these cars.

    I would suggest adding a line for 'owned car since new' or 'CPO/lease turn-in'. Id bet lease returns or CPO cars or possible trade-ins have had the worst oil changes. 15k or more between services, which definitley will not help bearing life.

    Dalvin Cook - 5.011 206* RB, FlaSt Positives: Looks the part. Thickly built, muscular athlete with good bulk and overall build for an NFL lead tailback. Compact, lean player. Looks to have legitimate sub 4.5 field speed, routinely outruns collegiate players to the boundary. Difficult to catch or chase down once in the open field, has another gear to separate in the third part of the field. Flashes nuanced, patient vision as a zone runner. Routinely identifies the backside opportunity. When needed, presses downhill adequately in man and power concepts. V good play strength, secondary-level players want nothing to do with him (see Mackenzie Alexander in the '15 game). Runs with forward lean and delivers compact strike to would-be tacklers. Unafraid in the box, not at all a finesse runner. Sufficient fluidity and lateral movement in short space; good hip and ankle flexion. Soft feet allow him to redirect with control and suddenness. Highly productive and can contribute in the passing game. Tenacious but raw as a blocker. Kid brother is a rising soph. at the same school. From the Little River area in Dade. Negatives: Not many from an on the field standpoint. Checks almost all the boxes you'd like. Doesn't carry quite as much weight as would be ideal; frame is likely maxed out. Field speed will need to be confirmed but appears to be v good. Sometimes shows some hesitance pressing the LOS in power concepts. Has had multiple off field incidents, one of which involved an assault charge against a female student in the area. Was dismissed from the team only to be re-instated; will need to be J flagged for that reason. Lingering concerns about a bone spur injury he suffered in highschool.

    Terry@BMS replied to a thread 335is 91 octane dyno testing in N54
    I was mainly focused on JB4 development but while it was strapped down wanted to see where the suggested MHD flash only off the shelf map falls. Out of respect for MHD I've chosen just to post the result and not get in to my impression of the tuning itself or how it drives on the road. Which I have also tested. One interesting thing I've found with the DCT torque limiter triggered on the JB4 DCT BEF is I've only noticed it on the dyno doing 5th gear WOT pulls at low RPM. Was not present during 4th gear pulls and I've never been able to recreate it on the road. It's hard to notice in a log if you're not also measuring torque on a dyno. But, glad I got it sorted out. Several other PUMP specific changes/improvements were made as well and again out of fairness I've not posted that data in this thread. Since we've been working on the ina0s DCT BEF I've also made some adjustments to the throttle mapping. It's smooth, strong, and shifts hard. Even more so now than before. But don't worry, we'll distribute the map changes to our JB4 DCT ina0s customers and continue development until they feel they are perfect. In terms of whether or not you'd personally benefit from a JB4 it all depends on what you're looking to do. This is a development thread not a sales pitch and it's clear you don't have a genuine interest in the JB4 so I'll leave it at that.
