I recently upgraded my 540i with MPPSK. what a huge difference it made.

Was checking the sport display as I knew in other models have been changed after MPPSK; mine is the same as stock (picture below).
Anyone with MPPSK software update seen any change to sport display?

Not that I use it, I just need to verify that the dealer did what they were suppose to do. It's been quite a journey with them and I don't really trust them.

Love to see your pictures.
Thanks.

You might try resetting your IDrive. Press the volume button for about 30 seconds and the IDrive screen should go blank. Let go, wait a few seconds, and then press the button again. The IDrive equivalent to the well known three finger salute for a computer.

See if that does it for you.

Tried it and still the same!

Forgive my igorance, what do you expect to change in these display with MPPSK installed? I'd presume that the added power/torque fits into the dial range displayed?

When you call the extra power, is it reflected on these dials?

Usually on other series with MPPSK this menu gets an upgrade. Higher torque and hp.
I just wanted to make sure my dealer did what they were supposed to do. I had plenty of issues with them!
And you're right. This menu is enough for the upgrade I've gotten.
On 5 series with B58 sport display is maxed at 400hp before and after. On 3 series with B58 max hp is 360 before the upgrade and then changes to what I currently have.

ok, but to be certain they effectively activated the power upgrade, when you floor it, do the dials effectively show higher numbers then before?

Tried it yesterday. It does!

That's good news! It demonstrates that the extra boost/torque is not conflicting with the identical range of the scale (or vice versa).

When you keep doubting the effect, you could consider to get it on a dyno. That would be a 50$ good spent to get your peace of mind?

If it pops consistently in Sport+ you know they did the software. They gave back the old torque converter so I think between that you can be confident everything was installed.

Why do they install a new torque convertor, I presume there is at least a 8HP50 installed in a 540i, no? That should be able to cope with the 500Nm of the MPPSK?

A change in the stall speed likely. The torque converter in the MPPSK is the same one they use in the ~380+ HP configured B58 ZF8 cars (M340i, etc).

Update of this menu is completely independent of the tuning done on the ECU. Some may just change the sport displays alone without any tuning on maps. Or some may modify maps but left sport displays alone. Also, this displays are not accurate. My 1.6lt G30 520 hits up to 320 HP at WOT

Hi all - I read about the mppsk upgrade and is there anyone in Southern California that have did this? Talked to a few BMW dealers and they never even heard of it :/

To order the part, it will have to come from Germany as well as it's all out of stock

Yeah I remember even in my case, I had so much trouble with dealers. Most didn't know about it. I've got the last MPPSK in NA at the time ( I think from NY) and CF tailpipes came directly from Germany.
From my experience, don't tell them MPPSK; for 540i, the know it as power and sound kit.

Would it be detrimental to run the stock converter with a higher HP/TQ flash tune (e.g. BM3, MHD, MG Flasher, etc.)?

I've been running BM3 Stage 1 and then 2+ for about a year and a half on my stock converter. I do have xHP TCU tune to remove the torque limiters and increase line pressure due to the added torque from the flash tune. The transmission has been holding up fine, but I'm wondering what I'm missing (if anything) by not having the uprated torque converter?

Unless anyone's a BMW engineer who knows the detailed specs of the two torque converters my guess is as good as theirs.
Specially with these cars being relatively new, I haven't seen a single thread anyone changing torque converters because of issues.
All I know with the MPPSK I've got a way faster gear change which is similar to BM3 stage 1.
We gotta check maybe xHP has a higher TCU tune for M340i because of the torque converter.

I am curious also...I have the free mppsk from bm3 and stage 1 93 for a yr now without any issues... and certainly bm3 aren't suggesting torque converter change for their tune

I have 480 and 560 respectively on my 540...idk if this is the original or it changed after my flash

[SEA6MT]

480/560 are the same values on my 540i with BM3 s1 93octane with XHP installed.

Anyone know how accurate or not these displays are? I recently reflashed to 93 octane and am getting 475hp/490tq readings from slow rolling start. Prwviously was getting close to 420/420 on 91 map. I know the difference in values isnt the octane just noting the only changes.

[Chappers 71]

It’s my understanding that the display reads 2 parameters from the ECU, that is torque and RPM and calculates the HP based on these numbers using a very simple formula, so yeah it should be accurate.

My G31 540i also shows 480bhp & 560nm of torques & easily reaches both.
The G31 was already mapped when I bought it & has a cat back AC Schnitzer sound pipe & exhaust.
I know that it’s quicker than an F82 M4 in a straight line
