Any member with a "30 Jahre edition" M5? We can code all of our M5s if we get info!

[lfelunden]

Hi guys

Is there anyone with the M5 "30 Jahre edition"?

It has shown to deliver around 605-610WHP stock!!
If we gain access to the DME information like I have gotten from a M5board member on his M5 CP we can code/flash our cars with whatever flash we want
Now we are digging a bit more into the CP flash. Why stop here, the 30 jahre sounds more promising - ALSO, no hardware changes has been done from M5 to M5 CP to M5 30 jahre - A higher sounding exhaust will not gain anymore power.

If anyone want to help out here let me know, PM or post!

Thanks

How do you know there is no Hardware change?

Because the new M6 CP will feature the same amount of HP with no HW changes. It's based on the competition package, we all know the difference is steering changes, suspension changes and the exhaust for more sounds. BMW called the "15 HP increase" a gain from higher boost.

"The foundation for these upgrades was provided by the Competition package – itself a car that already came with a power upgrade."

that would be the best thing in the world

[A_]

Competition Package "+15 HP"
575+ ~12~15% more

30 Jahre / Competition Package "+40 HP"
575+ ~22~25% more

check your pm

I have a new CP and was just reading up about CP vs Jahre as well. It does appear there are no hardware changes at all... just 'software tuning'. But how on earth do we prize that off a BMW dealer... willingly?!

Qadhi79 has a access to one of these 30 jahre M5's, hopefully we will be able to gain info about the CAFD in the DMEs (ECUs).

From what I've seen, the tuning changes are in the dme ecu firmware itself, not in the coded cafd.

Meaning that we can't flash cp/30 onto other vehicles. You may be able to flash the dme values but it won't have an impact, like how you can code the top speed limit higher but it won't do anything because the ecu itself is locked.

Only known way of doing it is how all the flash tuners are doing it now, physical access to the dme and drill.

Sorry but, this is possible and people charge upto $500 to flash your car from a NON CP to CP.

Go search before posting The limiter has something to do with the DME timer, but CP can be retrofitted, if that is possible why shouldn't it be possible to attain the 30 jahre flash too? Same story, no HW changes.

[v3n0m]

You're free to try. I'm aware that people have (and charge) for this type of flash, but there hasn't been any evidence of it in fact working (no dyno proving an HP change, etc.). Honestly, you're not going to tell that there's a 15 hp gain from a CP without throwing it on a dyno.

I'm just providing the information I've found while digging into this.

re: DME timer, it locks down certain aspects of the DME (including top speed limit) after the vehicle has been driven a certain distance/time. From what I can tell, the CP/30 tuning params are also locked down in the same manner.

Edit: See: http://f10.m5post.com/forums/attachm...3&d=1375812205
It's only top end torque/hp that's impacted, so pretty hard to tell (and small enough) that you'd really have to measure it to know if it's actually there.

Sorry man, but as you think I'm doing all this for 15HP you have to think again.
The CP is pusing out 649HP crank and measured many times, the 30 jahre has around 605-606WHP (700HP crank). NO, it is possible in Europe to retrofit the Competition Package, if THAT is possible, it is also possible to do the 30 jahre flash Know your facts, the limiter is a different thing vs this!

I know my facts. It's not codable as you mention (ie getting the ncd/cafd is not going to help you as I've dug into both cp and non-cp ncd files and nothing there impacts performance).

If you believe otherwise feel free to point out the actual coding params that you believe impact engine output.

Not sure why you bring up crank horsepower as bmw's are known to be underrated from the factory.

[v3n0m]

I'll even kick it off. Here's my DME CAFD (non-CP).

Feel free to run it against a CP or 30 jahre, or modified CP tune DME file using ncdtool and point out what coding params are different (literally 1-click).
http://www.bimmerfest.com/forums/sho...d.php?t=749668

You seem to be convinced there is a difference in these files, so I'm assuming you have at least the CP file?

Same story with the CP

[v3n0m]

Yup, aware of that thread. As I mentioned in a previous post, this is a firmware flash, not coding. You don't need the ncd/cafd files as you mentioned. You need the VO and SVT of a CP/30 Jahre to figure out what you need.

Problem is (from what I've tried), is that I can't activate the FA since you need appropriate FSC codes.

I will do a DIY for those interested or assist them remotely when my car is back. Has been at the dealer for 24 days now..

[Wills2]

Has any magazine figured the Jahre? IIRC Motor trend figured the M5 at launch with a 7.8 sec 0-100mph time others have been in and around that figure give or take 1/2 a second.

It's great to talk about crank or wheel HP, but the proof is in the pudding.

[Phatcat]

I have from Sport Auto, individual test.

CP Jahre
0-100km 4.2 4.1
0-160km 8.4 8.3
0-200km 12.6 12.4

80-120km 3.6/4.4/5.6/8.5 3.4/4.5/5.6/7.9
80-160km 7.2/9.3/11.5/16.4 7.2/9.2/11.5/15.9

However, there's a curveball, Sport Auto once did a comparison between the M5 CP (different car than the one above) and XFR-S, and that CP turned in:

4.1
8.2
12.3

3.4/4.3/5.4
6.9/9/11.2

Of course, weather conditions might have been slightly different, but throw in engine tolerances, there's practically no performance difference between the CP and Jahre.

Not many have vbox data and or dynoruns from the 30 jahre. Would be very nice to see those. Only one german magazine has done a dynorun on the 30 jahre, it did around 605hp to the wheels!

Maybe all those CP press cars have the Jahre tune, who knows. Guess it would be nice to have a private Jahre and CP data to compare, otherwise according to Sport Auto, CP cars can be faster, it was quicker around the Hockenheimring than the Jahre too, 1.13.0 to 1.13.2.

Compared to the non CP those two sure are beasts in performance! Nice comparison yeah

What if the 30 jahre actually has the same flash as the CP but downpipes with race cats??
