Default For those who don't like the Alpina B3 trans flash - 11-10-2013, 07:32 AM

I like the Alpina B3 trans flash with the gear indicator even in D and S mode, and for the fast response for upshifts and downshifts.
But I don't like it in Drive mode because it upshifts too soon, approx. 1500rpm.

So for those like me who don't like this upshifts in D mode, but still want faster upshifts and downshifts, follow this DIY:
http://www.n54tech.com/forums/showth...ghlight=Alpina

but instead of uploading the ZB 7615835 (Alpina B3 trans flash), upload the ZB 7603527 ( BMW 2011 trans flash).

You'll not have the gear indicator ( D1, D2... S1,S2...) but you'll have upshifts and downshifts as fast as Alpina B3, and upshifts in D mode will appear at 1800-2000rpm, which is much better for me.


************************************************** *********************

UPDATE November 2015:

here is a good summary, found on another forum:

ZB 7603527 (BMW 2011 Flash)
- No gear indicator
- D shift rpm raised slightly ~1800-2000
- Downshift rev match not like Alpina but better then others
- 6800rpm shift point


ZB 7615835 (Original Alpina B3 Flash)
- Gear indicator (D1, S1)
- D shift rpm relatively low ~1500-1800
- S mode shift rpm 2800-3000
- Great rev match downshifting
- 7000rpm shift


ZB 7603537 (New Alpina B3 Flash)
- Same as 7615835 except:
- Smoother
- Slightly higher RPM S mode upshifts ~3300-3500


ZB 7603541 (Euro Sport Flash)
- No gear indicator in Drive, M/S still have it i.e. S1...S6 / M1...M6
- D drives just like the stock
- S a bit more aggressive than stock


ZB 7601494 (US Sport Flash)
- No gear indicator in Drive, M/S still have it i.e. S1...S6 / M1...M6
- D feels stock
- S stays in gear longer than the B3, Shifts at ~3300-3500
-M is more impressive than the B3 at shifts



I'm using the Alpina 7603537 trans flash, and my custom trebila performance flash tweaked specifically for AT with alpina trans flash, and here is the results in D mode at very low pedal input, upshifting between 2000 and 2500rpm, as it should be:

Default B3 Alpina does actually adapt to your foot - 11-10-2013, 01:07 PM

In my experience, the B3 Alpina TCU flash does actually adapt to your foot. If you baby the throttle driving around town it'll shift at ca. 1500 rpm. If you drive more aggressively it'll up shift and downshift at higher rpms in D mode as well as S mode. Really! Try it!

Yes, All the trans flash do that, but I prefer to shifts at says 2000 rpm, even at very low throttle.
I've been using the 2011 BMW trans flash during 5 month, and the Alpina B3 one during 3 month, and in my opinion, the best trans shift behaviour is the BMW 2011 one.
The Alpina b3 one have 2 advantages: the gear indicator in D and S, and the high rpm shifts at 7000 rpm ( 6800 with the BMW 2011).

Agreed...in drive with the B3 flash it shifts a bit early...I hated it at first but like it for a few scenarios.

1. Wife driving
2. Freeway cruising (in sport it'll shift down to 5th at 75mph if you set the CC)
3. Loafing around town

However, I have paddles so for the most part I'll leave it in sport and use those.

The other thing is that since going with the N55 mids, a shift at 1500rpms sounds a tad bit raspy...so I typically avoid that. May try this flash and see how it does as 2k+ shifts sound much better...

Thanks for the update and info Trebila...

I didn't post this information on this site, but you also have the option of Sport AT also. You get the standard D in Drive, but you also get the S1 S2... in Sport. It's a bit more aggressive than stock in Sport, but D drives just like the stock D.

Try 7603541 Euro or 7601494 US

I honestly don't know if there is much of a difference, but you won't hurt anything trying them both. Just disable UIF write so it doesn't update your UIF... Hopefully someone can post up the differences if any.

Thanks Wedge...also, do you happen to recall which file was the stock one? Somebody was asking me about it and I know it's out there but figured you'd know.

Will do, but I probably won't play with this for a bit. Much prefer turning a wrench to playing with software and I want to get this testing done so I can move on to supplementary post FMIC injection

Tried this (ZB 7603527) today on mine (05/2007) and it was a no go. I had to go back to the B3.

That one sounds much more interesting to me.

Good information.
But can you confirm the shiftings (up and down) are as fast as the Alpina B3 one?
What is UIF?

Did you not like it or did you have problems flashing it?

Gave the "car on lift" error in the dash. Didn't shift properly. Started out in 2nd. Wouldn't go into S mode and the paddles didn't work.

It's working fine for me so far. Shifts are not as crisp but still quick. D mode is a lot better than alpina, for me at least. Shifts around 2k. I still need to test it for a few days to make a decision.

Low speed shift points can also be manipulated by adjusting torque request tables (Requested Torque %) in ATR and probably the BB flash. For instance, lowering the factor in each of the Pedal Position % columns will cause the trasmission to upshift later. It also makes the car downshift more easily when pressing the pedal down. (I believe the DME observes pedal position for shifts, not throttle blade position). However, the downside to lowering the factor is that it lowers pedal sensitivity and makes throttle feel a bit laggy, which is not good if you like a snappy throttle. It works well for me though, because I don't have any torque down low with the single, so a later shift helps keep the car from straining and moaning under light throttle.

Flashed the 7601494 successfully. D mode feels much more like normal. S mode stays in gear longer than the B3. Mine would shift at about 2800 - 3000 RPM on flat ground with minimal throttle. It now shifts at about 3300 - 3500. M mode is more impressive than the B3 at shifts. The car slams into gear and I had wheel spin from 1st to 2nd on both occasions when letting it shift by itself. This is new for me since I am an xi. However, it is too early for me to say that I will stick with this one. Lets see how it goes once adaptation happens. But for now, I like it!

Ok. Can you explain more?

I'll try 7603541, 7601494, and let you know compared to 7603527.
