lol true that. I'm with Jonmartin on this one, PG is no better when it comes to what he's accusing Jonmartin about..
He even manipulated my comment on when I wondered the coincidence of him posting about how dyno operators cheat right after my Gintani dyno thread. I just stated it was a coincidence and he deleted my comment. I'd rather have anyone else regulate the thread than someone who can't seem to accept superchargers will probably make more power, and that full bolt-ons on the 4.0L V8 has the potential to hit approximately 500hp.

Guys, let me clear this up: This is not the right place to bash each other or to slam other tunes/systems or to rehash old threads and arguments. This stops right now. The OP has been quite specific in his questions, so please address them or just move on. Any further attacks are subject to infractions. I did let some comments go in this thread, but won't do so any more.
Best regards, south

Southlight,
I have nothing against Robert or RD sport but Robert stands up for RD sport/Stroker motors like there is no tomorrow, which is fine. But you should also let the other members discuss how they feel. This is a forum, we all come on here to voice our opinions. Threatening the members and saying further "attacks" are subject to infractions is just shutting us down to voice our opinion. We are all grown men, I'm sure we can handle a argument. If we are going to get infractions for speaking our mind then what's the point of being on this forum? We all get "attacked" but all of a sudden it happens to a moderator, the sudden change of heart?

The lag is not an issue for me and never has been. I am curious what the DCT remap is that most supercharged cars seem to be getting. Maybe sammy can enlighten us?

So Optherion, what are your thoughts so far? Would be great to know and see how the mods come along.

I'll stay out of the big argument, but I was in the shower after the gym thinking about what I should do in the future with the M...and for some reason another thought came to my mind about OP's question...since it seems like E9X M's are going to be the last NA M's, why don't you just leave it stock, go with bolt on's which will give you more torque, and/or in the extreme case go with stroker? Since it seems the next M3 will have a turbo engine you can get that one in the future and enjoy it then?...don't know, just a thought...
btw, I'm absolutely 50/50 on stroker vs sc...I love them both. From my experience, car's with turbo's always perform higher vs NA which have similar HP and torque numbers, but since BMW is sadly but smartly changing their future M engines to turbos, I think we should enjoy this last one as it is...NA! plus, in OP's case as in my and I'm sure many others, we don't plan to race or have THE fastest car..so no point going for slightly more performance at a slightly higher risk... |

I guess some helpful information in this thread can help keep it open For those asking about DCT software I can help shed some light on it. We have been working with the DCT software for about 6 months. We have done lots of testing with several different software versions and have figured out the issues around DCT and high HP.
The factory DCT software was designed to keep drivers safe. This is done by delaying the downshifts by almost 2 seconds to the transmission and slightly slipping the cutch. This is done so that drivers in certain situations dont flip the rear end of the car out. This is also what customers experience as lag when the car begins its downshift cycle and you get on the gas, you sit there waiting. The problem this software will cause when you add high TQ and HP to the car is when you downshift under WOT the built in delay along with added TQ confuses the tranny and your 2 sec delay becomes a 3+ second delay until the clutch gets engaged. During this time if you do not let off the gas your RPM's will shoot up and when the clutch does finally try to engage it tries to engage as it would with 400 HP and it slips causing a transmission overheat / malfunction. This happens in D mode when you floor it sometimes as the transmission tries to downshift and it happens in Manual mode also. There are no issues with upshifting when you run the stock DCT software on a supercharged car as the stock DCT software engages the clutch very quickly during upshifts. There are a few solutions to this problem. One is to have a custom DCT file built that will slightly impove the clutch engagement during upshifts but will also remove the built in delay on downshifts. By having the software engage the clutch as soon as it is told to downshift and also slightly reducing power to the engine during this very quick period you can have the transmission perform flawlessly in all conditions. The second is to limit the power and torque in the car so that the transmission can handle the added power during downshifts. We have found that the limit for power on stock DCT software is about 575 chp and about 380 ft/lb tq. If you keep power at this level the DCT performs ok during downshifts under WOT with the factory software. Once you raise power to 600 + chp and 400 + ft/lb of tq the transmission begins to have issues with downshifts. The other issue with DCT once you figure all of this out is being able to provide the customer with a custom DCT software file. The interface to access the DCT control unit is extreamly difficult to get. It is not a simple interface like the ones that can be purchased for loading engine software as the DCT ecu is in a difficult location to access and can only be flashed thru the OBD port. It also requires factory knowledge on how and where to load different version of software into the DCT ECU without erasing the current file and crippling the car. If you try to load a unauthorized file into the DCT ECU the ECU will lock you out and the transmission will be shut down. If you do this and fail to correct it you will need to buy a new $10k transmission. This is why we currently can only load DCT stage 2 software into cars that are brought to us for installation. I hope this information helps. Last edited by sales@ESSTuning; 11-13-2009 at 04:39 PM.. |

The point is the 1/4 mile illustrates power gains quite well. If the strokers really were so powerful don't you think they would have headed out to the strip to show what they could do and compare the results? We don't have a single slip from them. |

What you keep failing to understand, is no one said a stroker gets more power. Nobody said that. If you are 1/4 mile junky then yes SC would be the way to go. But honestly around a track, no question I would prefer to be NA. |

The point of a stroker is not to get more power? What is it then? To give you something to type about everywhere you get a chance? You go ahead and stay NA, the top E9X performers will be boosted, end of story. |

The forum is a riot. What jonmartin said to you has nothing to do with me, maintain your focus. Who called you an NA fanboy? You said you would rather be NA, did you not? What is it exactly you are saying because you continue to type and provide nothing of substance. |

Maybe you should speak to people who have FI on the M3 and have tracked the car? PM niterider, ask him about his experiences, and then you will have a base from which to speak from. The 1/4 mile and highway belong to the SC as you said. The track does as well. |
