Does anybody have a spare TCU they are willing to send for him to use as a testmule?

I'll try the Alpina file later on.

I took the plunge - updated with WinKFP in Comfort mode, selected the alpina file and crossed my fingres. 2 minuter after - SUCCESS!

I have only driven it for a short drive, but man it shifts quickly! D shifts earlier than standard which is fine by me since I have 512Nm, should help on MPG. D1,D2,D3 etc. are awesome. I have not tried to give it the full beans yet, so I cannot tell the revlimits in S and D modes just yet.

..But I can confirm the Alpina file (7615835) work on a 325d with AT hardware: 7591971

..There is no such thing as free lunch.

When flooring it - it doesn't change gears, it just keeps the revs at 5100 rpm. This goes for both sport and drive. I *think* this proves my point from earlier that the way the torque curve is shaped also gives the chnage points at full throttle as the alpina file is made for a petrol engine reving higher.

But the way it changes gears in D are just absolutely awesome. (when not flooring it) The downside is that it is a bit slower to select a lower gear (in D) if you give it some pedal.

I'll try to adjust my remap to give me a different torque curve at 4000+ rpm, to see if that helps

E91 325d with retrofitted paddles, shifts like it is possessed by some sort of animal. In D it's smooth, in sport it's a bit quicker - but in manual with paddles, it almost "hammers" the gears in - in a good way. Man, it feels nice.

That kinda makes me want a better firmware for my E91 pre-lci 330d (6 spd zf 26 unit) - my god, it's slow as f*ck.

Although petrol software for a diesel driveline probably isn't that smart of an idea. As mentioned elsewhere, the TCU in the diesel takes into consideration the less smooth nature of a diesel, to make sure the driveline is "handled with care".

Mik325tds you have a PM

Anybody know ZUSB for an Alpina B3 ? (The 2L biturbo diesel). Does it also use the ZF6HP19?

Yes, WinKFP will flash any calibration as long as the "hardware" number (7591971) is the same. However, the hardware number is really the base software of the tranny. The 335d uses 7591972 and has very little change in it. So I'm hopeful that we can maybe flash the 7591971 base SW into our TCU so it would accept the map file of the Alpina (7615835). Reading through WinKFP users guide, this should be possible in Expert mode. But I really don't want to brick a TCU by trying this. So we need Roberts service to be able to restore the original memory content of the TCU.

One 'funny' thing. When I did the first update from the ancient 07 SW to the newest the flashing took ages. I got the progress bar three times total. When I flashed the Alpina file I only got the progress bar once and the flashing was done in about 3 minutes.

Do you know what the differences between the two are?

Hmm, I suspect 330 uses the same, correct?

What about downshifting? My biggest issue with this transmission is when I command a downshift but it doesn't respond, presumably to avoid overrevving the engine.

That said, my concern with your flash would be that because the RPM limits are based on a gasser's redline it would willingly initiate a downshift that might overrev the engine.

You put your foot down slightly it will downshift in S mode it down shift even quicker.

Compared to the standard auto transmission it is noticeable quicker downshifting

I was referring to downshifting using the paddles or the shifter while under braking, like at the end of a long straight away where you need to go from, say 120mph down to about 45mph and drop 2 gears.

Haven't tried that, I'll try it on my way to work with the legal speed limits and update you

Unless you're in D and "only" give it about 65% throttle - then it's slower than the std. map.

Have you changed the configuration settings of WinKFP? You can force it to reflash the base program even though it is the same in comfort mode. You can also choose to update the bootloader. That would then make three separate flashes.

Nope, no Changes

Just a word of caution for you guys flashing various software with WinFKP.

Please understand that there is a good chance something will go wrong at one point. Bad Cable, Battery etc. We all know this, just be prepared and watch your nerves when it does.

It's a horrible feeling when a flash fails and WinfKP decides that it can no longer communicate with the processor.

At least one of you should have a really good understanding of the WinfKP Expert mode and document the following for your TCU.

ECU Address
P-SGBD File for flashing this is a *.PRG file
PABD file for flashing this is a *.IPO file

You will need this information to recover from a bad flash.

Somebody with a 335i og 325d/330d (not running alpina flash)- can you please try and log the following for me in Test-O.

ECU: GS19D
Job: STATUS_MOTORSOLLMOMENT
value: STAT_MOTORSOLLMOMENT_WERT

I'd like to know if this is the Torque limit reported by the gearbox - or if it's just "something else".

Maybe if we'd tweak the DAT, HIS and HWH files, we could get WinkFP to flash the GKE215/Alpina soft onto the 7591972 hardware? The base program is only a few bytes apart and the risk to brick the ECU with a 0da file is quite low i guess.

No need to mess with those files. Expert mode will flash just about anything. If it's incomparable, you have a brick.

Probably recoverable but for some reason I can't get winfkp to talk with my TCU. So I'm far from an expert.

INPA communicates fine, too busy with the DME tuning to look into that problem right now.

[RBT-Tuning]

I never tried Expert Mode, but that means we just need a brave guy to try that.

That's just torque vs. drivers wish. Not the limiter.
