There's a message with ARBID 0x315 which BMW called "Vehicle Mode". On the E60, this message is broadcast by the SZM model (center switch module). The message is two bytes. The first byte constantly cycles and appears to be a timer. The second byte is either F1 or F2. If it's set to F2, the DME will enter sport mode. Otherwise it won't. As far as I can tell in BN2000 cars, the DME itself doesn't broadcast anything to tell other modules it's in sport mode. So the transmission and cluster probably also look at that message 0x315.

In LCI E60s with the sports automatic transmission, all of the above is true, but the sport button isn't wired directly to the SZM. Instead, it's wired up to the GWS module. While the button is being pressed, the GWS module broadcasts messageid 0x28D with data "EF FF", and when the button is released, it broadcasts "DF FF" 3 times. A single "EF FF" followed by 3 "DF FF"s seems to be enough to trigger the SZM module to change the sport status to F2. There's no checksums or timing sequence on that message ID.

Now in the E90s case, the DCT models *did* have a sport button (and it seems to work pretty much like it does on the E60 -- button is wired up the GWS module, which then does its thing). So perhaps the "easiest" way to add the sport functionality would be to throw an arduino with a can-shield on the PT-CAN bus, and just send that 0xEF FF when the button is pressed, followed by the DF FFs when it's released. Should be really easy to code instead of having to worry about timers and such. You can also trigger an LED based on what's being sent on 0x315

I tried to send 0xFF 0xF2 on 0X315 ID every 20ms with an arduino, and i was able to enable sport mod on my EDC16c35, after setting up FDC self REC and all this stuff.

look like my DDE don't care about first byte.

Hey I know that there was some talk about tuning for the GM 6L45 auto transmission. I thought someone said that they needed a transmission to test or the TCU out of a trans.

I just happened to look on ebay and these transmissions are quite cheep.
Here is one=

If there is an interest in working on tuning this TCU, I can contribute.
Let me know.

[E90dima]

Any chance of posting the oda file for the x5 n52 270hp? Has it even been tried?

[hassmaschine]

We looked at it ages ago. Tune is basically the same. I speculate there must be differences in the exhaust - and anyway theres nothing there you couldn't do better with a tune.

[The-Traveler]

Are you guys selling the 330 tune yet?

[hassmaschine]

The "stock" 330i tune is available for most N52 powered models on Bimmerlabs. I haven't built a 328xi tune yet, but I will be doing so soon.

I thought you were going to offer an enhanced version without the soft rev limiter and a small bump in power. That's what I recall from reading this entire thread 6 months ago.

[hassmaschine]

Sorry, you must have misread. I never offered anything for sale in this thread - this was started for my own personal tuning efforts, not intended to sell tunes. Right now what I have immediately available are baseline 'factory' tunes for those who have done 3-stage swaps (files available free).

I can of course tune with increased power and no soft limiter - but not for free. You're welcome to inquire further if you have more questions.

I remember that you had a nice tune that you were happy with and I'm inquiring as to how much you would charge for this tune.

[The Nightman]

My apologies if this is the wrong place to ask, but does anyone know how they squeeze out an extra 5-10 kW on these models?

195 kW Applications:
2005-2008 E85/E86 Z4 3.0si
2006-2009 E87 130i

200 kW Applications:
2006-2010 E83 X3 3.0si
2006-2010 E70 X5 3.0si, xDrive30i
2007-2010 E63/E64 630i

https://en.m.wikipedia.org/wiki/BMW_N52#N52B30

I'm assuming the BimmerLabs 330i file is 190 kW (255 hp)?

[Taskmaster]

Hey Hass, any benefits in having you do any tweaks to people who have existing tunes?

[hassmaschine]

they basically have more ignition timing out of the box, there are other differences but those are the most obvious changes.

yes the bimmerlabs tunes are the 255hp version. Actually the 130i is the 265hp version, but that's because there's no 255hp version of that car.

Thanks for the info! I've set up my project on BimmerLabs and just finished setting up BMW Standard Tools 2.12 and WinKFP. Once I get the BimmerGeeks cable, I'll install the 3IM and attempt to flash the MSV80 RSA Delete and 328i to 330i file.

A few other members have mentioned a flash for the GA6L-45R transmission; is this something I can also flash myself? I don't see any transmission flashes as available downloads for my E90 (serial E127137).

Thanks for your time and help!

If there's something specific you're looking for, sure.

If the N53 software happens to use the same program version (or at least the same boot sector) as the N54 software, then there's pretty much no extra work needed on our part. Otherwise we'd need to figure out where the branch instructions we need to modify are and then locate the powerclass byte, but that's not super difficult.

I want to bring this up again...is the modified Software for n54 public? If yes, where can I find it?
Would like to compare n53 and n54 bootloader.

Shouldn't it also be possible to flash this n54 Software, change powerclass and then go back to n53? If it has the same address in eeprom, this should also work?

[hassmaschine]

Which N53 are you wanting to modify the power class on? do you have a ZB#?

I'm pretty sure the N53 runs on the same code as the N54 (at least, specific versions of it do). If so, the same N54 0pa would work on the N53, assuming we had a matching N53 0da that has the calibration you want.

[PD330]

ZB is 7642442. It is an european 325i with auto transmission. I also posted a full readout in post 1710

[hassmaschine]

right, do you have a ZB# for the file you want to flash? I presume you have an N53B30, but with a single stage?

This should technically be a simple file to create.

[PD330]

Yes, its a N53B30, currently with single stage. But manifold of 330i will be used later.

New ZB# of the 325i would be 8619314 (8619315.0da and 7612455.0pa).

I THINK ZB# of 330i should be 8619316 (8619317.0da and also 7612455.0pa). But this is only what I found online somewhere, not sure if this is correct...I could just try to flash and see what happens.

EDIT: Corrected zb#. Its correct now.

[hassmaschine]

You can flash it but it will run in limp mode.

I'll try in the next week to look at those files.

[The-Traveler]

Is there any way to get more out of the 06 N52 330I, with just a tune? If so, how much more?

I have charcoal delete, K&N and that's it.

[hassmaschine]

A little - maybe 15bhp. Best bet is a 3 stage manifold.
