I think the real reason for BMW (and Porsche and Audi) pricing being high is that few of the popular tuners actually develope the engine control system in-house. Almost all of them rely on 3rd parties for ECU flashes. Also, none that I know actualy do in-house calibration. Instead, they usually just try off-the-shelf flashes from GIAC until they find something that works reasonably well with their kit. It's unreal how many people I meet in this industry who tell me their car got "tuned by so and so." I ask them how long the tuning process took and what kind of questions did the tuner ask them only to find out that their definition of "getting tuning" was trying flash after flash, through the mail, until they find one that works adequately at best. The only BMW tuning shop I know of that actually does in-house calibration is Dinan. I've seen their facility and was given a tour by Steve himself. It's a very impressive place. Of course, you pay for it. -shiv |

Agreed. I am just glad to see the PROcede with exceptional gains at a nice price.

Shiv, If you're ever in the Charlotte area PM me. If you liked Dinan's shop I'll show you a shop that will amaze you.

Issues with the N54 motor.
Quote:
BMW is working at releasing an N54 HP motor by the end of this year. Although the platforms that will be equipped with this version have not yet been decided, it is safe to say that the E90 through E93 platforms will get it as soon as it is available. The expected HP rating is around 355PS, up from the standard 306PS of today's motor. The current HP test engines have exacerbated a problem that already exists on the current 306PS motor, where the temperatures of cylinders 5 and 6 are higher than expected and are a huge cause for concern. BMW is looking at a solution to this problem, and is also anticipating that they may experience some engine failures on the current motor. What is clear, is that they heve to wrestle the cause of the problem, and/or find a solution, before they release the N54 HP version into the market. In typical BMW fashion, these issues are monitored without being made public, as they do not want to have to answer to any unwanted warranty claim, or even worse, be forced to issue a general recall that may prove to be unecessary, as they will address the isolated cases on a one-by-one basis. This is no different than how they handled the piston ring/oil consumption problem on the early S62 motor. Don't be surprised, if they should decide to keep the standard 306PS version alongside the HP (i.e. in the 135i), to see next year's engine to be a little different than what is offered today. If any of you have driven your 335i hard, you may have noticed a tendency for the oil temperatures to be a little high. The problem is that the temperature gauge is measuring the average temperature once the oil recirculates, so you can imagine, if cylinders 5 and 6 are the ones generating most of the heat, that this is an area that could be prone to failure. Recently Alpina introduced their Alpina B3 BiTurbo at the Geneva Auto Salón. The car is rated at 360PS, and this is the level of power that BMW feels safe with at this point. We may sit here and go back and forth on who of the vendors on this board produces the most power and why, but surely nobody will try to argue that Alpina does not have the resources, nor the expertise, to extract every bit of power from the N54 motor. Just keep in mind that they have had experience with turbocharged BMW motors that goes back 30 years, and have been consulting with BMW on the development of the N54 motor itself. Like Alpina and BMW, Racing Dynamics S.p.A. and its U.S. arm RDSport are approacing this subject with caution, and our current offering is a result of many factors: the main one is the oveheating issue, but most of the others haven't even been mentioned anywhere in this thread. Good luck to all. Racing Dynamics S.p.A./RDSport Federico L. Pavoncelli President |

Addendum
Sorry, I forgot to mention that I am currently in Europe and this coming Friday I will be at BMW to discuss a few technical issues, one of which is the subject of my previous post. I will try to remember to give you an update after the meeting. Should I forget, please send me a PM as a reminder. I may be flying back to California, but I will do my best to share the information.

So the 335i will carry a HP rating of 355?? Is this still using the twin turbo set up? Seems like a bold step particularly if the M3 is going to be rated at approx 420.

If cylinders 5 & 6 run so much hotter wouldn't they be prone to detonation or is that completely alleviated by the direct injection? I would think you would still see some knock activity if they were dangerously hot.
Shiv, have you logged EGT's on these cars? 360 PS is 355hP so, it looks like the Procede is still safe by the info above. |

I have been lurking on this board for a little bit. I have finally felt compelled to post because I see that there are so many questions out there. While I see that Shiv has contributed a lot of information he is only one person and people have a lot of questions... Hopefully Shiv and everyone else will welcome someone from another company who also wants to develop product for the 335i and provide data to interested enthusiasts.
Let me introduce myself... My name is Merritt and I am currently an engineer at Turbonetics (http://www.turboneticsinc.com). Previously I was an engineer at AEM. I have had an E46 M3 for the past 3 years. I have ordered a 335i which I will be trading the M3 in for. The car is in transit and due to arrive next month. I will be collecting a lot of data on the car for product development. I will also be logging the process for media outlets. I will be happy to share my findings with everyone here. |

Nice to have you aboard. Back in the day I had a nice view of your building and Vortech's from my office in Moorpark (Kretek Intl).
