So wait the alpina flash raising shift point from 6800 to 7000?

Seems that the 7603537 slipped when really pushing it (24psi) so maybe not as good as its been described and as wedge says its an older flash anyway.

Same post however does have a +2 for the 7601494 flash where it looks like it been running a stage 2 motor for almost a year.

Im temped to give it a bash but the 7603537 slipped out of gear and RPM's hitting 8000rpm would be a sh!t yourself moment!

Eh, well, then I'm really confused now then because Wedge was the one that told me 1494 wasnt for the tranny in my car and one of the alternatives was 3537 which seems ok. Perhaps I'll just go back to stock for now.

7603527 is a flash for the E82 N54B30ATL and release in 2009, so I'm not sure how anyone made the assumption it was a 2011 sport flash.

7603541 is from an E89 N52B30OL. Not even an N54 transmission flash.

7601494 is also an E89 N52B30OL. Still not an N54 transmission flash....

I dont think it is, its for a Z but folks have been using it. Seems there is no best of all worlds flash and the B3 is rubbish in drive due to emissions regulations. Shame someone cant work out how to edit it in drive mode and we would all be happy!

Here is a good thread where all flashes have been tested:

http://www.n54tech.com/forums/showth...t=22180&page=4

For me im going to leave it with B3 flash since above post has conflicting opinions again. Maybe ill just drive about in S mode more often! Im going to do a muffler mod and quad tips next!

What power are you running? Seems that most of the flashes on the list are OK to run on stock power and that problem creeps up when power gets much higher than stock. I dont want to risk it as wedge gave me a tune thats 21psi and im pretty sure its running 420hp+. Not been Dyno'd but vitrual dyno checked out for all tunes i tested bang on what its supposed to be when i ran it against all my logs (stock, stage 2, stage 2 FBO, JB4 etc)

I'm pretty stock and currently only have JB4 G5 running map 5, with 2 or 3 gallons of E85 and the TCU flash. I already have a hard time with wheel spin from second to third, I am on run flats, with the way it is now so the fact I see guys on here running 5, 6, 800+ HP blows my mind but more power to them.

I have DCI's coming Monday and I should be getting DP's and a FMIC in February. After that I dont plan on any more modifications that will impact HP and will simply focus on suspension, brakes, and maintenance.

My butt-dyno (and research/reading here) has me in the low 300's but I've never had it tested. From what I'm reading low 400whp is feasible with the upgrades I want and seems to be pretty standard on the DD's I read about here.

I agree, I am a bit shocked that with all the 'coding' that can be done no one has ventured to create TCU flash that is similar to the Alpina but perhaps with a higher shift point in D. Maybe, the fact that once it makes its way onto the Internet there is no way to profit from it.

I saw another thread with a bunch of talk about throttle mapping and torque request in relation to D mode of the Alpina B3 flash but it seems to be a pipe dream.

I'd pay for a flash that had D stock shift points but the smoothness of the Alpina D mode, 1494's S mode and again, to beat the same horse, I dont use M really so meh.

Dude, no joke but ditch the JB4 (i did for various reasons including ECU lights and poor timing). Dont get me wrong its a very nice device and with all the options with amazing boost control but its no match for the MHD flasher app and wedges tunes. Im sure they have a E85 tune and its cheap so no big deal to try out and once you have all your bolt on bits ask wedge for a custom based on best fuel you can get and you will be blown away. You guys make me well gel with your ethanol content fuel. We get 5% max here.

Regardless of what your running (JB4, COBB, Proceed, MHD) you should log and see if your car is happy doing what its doing. That's a must in my opinion and easy to do with any tune option.

800hp on a stock internal N54 is not sustainable for long, pistons are not up for it as not forged, shame really. 500/600hp yes for many miles if its running right.

Im very temped to go meth over here. I want RB turbos as well so need to choose as cant afford both!.

I wish I could flash my trans. I have an early build (01/07). Its my understanding it can't be done unless I find a TCU that is dated 03/07 and beyond. They are at least $750.00 or more and that is a used price.

Oh well.....

That sucks indeed. You would be cheaper buying a full fooked tranny. Maybe an idea to ask about breakers and see what comes up.

Also maybe you can try one of the flashes for other gearboxes as I understand its just about ROM space so if you can find a flash small enough....

I switched from Alpina to the Sport flash, it's definitely stock-like in D. I hated the Alpina for daily driving because of how early it shifted.

IIRC, S mode doesn't shift into 6th on the Sport flash like the Alpina did.

I wouldn't know, my car is bone stock right now (selling it).

How long have you been running the 'sport' flash and wich ZB number are you running?

Don't ask me why I remember that. Anyway, UIF history for the GKE215 is massive in comparison to the DME where it only has the original and the current. Look at the history to find your most recent ZB#. Flash that if available. As long as the UIF information last entry is a ZB# specifically for your car, you don't need to select a ZB from WinKFP. It looks at the history in SPDaten and will select the correct ZB. F1, F3, GKE215, OK, F8, F3 (program).. This will prompt you of current, and new ZB # it will flash.

So I was going to flash back to stock today and I followed these steps but it says my last TCU update from dealer was in 2011 and the ZB number is 7601493. I only have 7601492 and 7601494 (which youve stated is for the Z series), how would I go about getting the correct ZB file?

I tried the US sport flash, 7601494. D is definitely better than Alpina, but Manual mode blew, it was almost like stock. Shifts were slow and mushy. I drove around for about 15 miles hoping it would get better but it didn't.

I went back to Alpina, 7615835, and despite the shitty D mode I like it much better. I drive around in Manual mode most of the time so it's not a huge deal.

Good thing you went back, 1494 is apparently NOT for our trans. I've also gone back to 7615835 since I dont have the 'stock' ZB for my car. After spending about a month on the original Alpina 760xxxx (I forget the number but its posted above) I can now appreciate 5835 a little more. 5835 DEFINITELY shifts smoother even though the shift points in D seem a bit lower. The smoothness negates the shift points in MY mind.

I'd still like to go back to stock though. Just for comparison.

[Maniac0908]

I came from the alpina flash. I hated it. I even think its what blew my tranny. I would be in 6th gear going 15 mph up my street. I switch to the us sport. I absolutely love it. Wont go back. I also read somewhere it can burn rubber in m mode.

P.s. can someone pm me about wedge tuning. I need a backend to go with my jb4.

Yea, I'm going to try the sport. I'm just worried it won't hold the power, wedge says its not for our transmission.

You think it can handle typical FBO?

I might just go back to stock actually. Alpina doesn't even shift that fast for me at WOT, there seems to be a delay.

I have the same feelings.

Went to the US Sport Flash last night, although D was better, it wasn't enough to deal with the laziness of manual mode.

I wish someone would make a transmission flash that took Stock D mode and Aplina D mode and met in the middle. It would be perfect!

So I'm back to the latest alpina.

Agreed, I went from Stock > Latest Alpina > 1494 (for the Z tranny I guess) > OG Alpina > Latest Alpina > Stock. I just use D too much to not be running stock. Stock D with latest Alpina S would be the biz.

Alpina feels like 0-40% pedal = granny mode 40%+ = all the boooooooooost
Stock feels like 0-25% pedal = granny mode 26-50% pedal = 'normal' driving 51%+ = all the booooooost

The S mode shifts in the Alpina are just so much more smoother when youre getting on it though.... arrrrrrgggghh

Yeah, I used super technical terms, I know

[335_MI6]

I swear with the alpina flash, D mode, I see bicyclist passing me when I leave a red light. The car just feels so slow. If someone told me it had 60hp I wouldn't question it. M and S are just too aggressive for daily driving

[Maniac0908]

How do you know which tranny you have. Are you guys saying if i dont have a z tranny i shouldnt be running the us sport flash?

See below, I'm sure there is MUCH more to be explained and taken into consideration but since Im new to this platform below is 100x more than I know about it

ZB # are incremental, and larger numbers are the newer files. 7615835 is the last Alpina B3s transmission flash that was released and has a direct impact on torque limiters. The Alpina flash is listed as an E90 N54B30ATL ECE flash and was released in 2010. It is the most recent N54 AT specific transmission flash that has been released for the GS19.11.0 transmission, again this is specific to the N54.

All of the 760xxxx files were done in 2009.

There are two older flashes you can try. 7603537 and 7603535... Both are E90 N54B30ATL ECE flashes.

7603527 is a flash for the E82 N54B30ATL and release in 2009, so I'm not sure how anyone made the assumption it was a 2011 sport flash.

7603541 is from an E89 N52B30OL. Not even an N54 transmission flash.

7601494 is also an E89 N52B30OL. Still not an N54 transmission flash.

There are a lot of GKE215 ZB#'s you can play with. Not all were designed for making the power our cars make. I have to laugh when people without any knowledge of what they are talking about release old ZB#s as newer numbers as if they found something new. Depending on the power you are making, chances are you'll have torque limiters in higher gears or your clutch pack will slip because the line pressure isn't high enough.

Here is a chart of what the different TCU flashes 'offer'. I've tried 7615835 and like you thought the shift points were way too low. 1494 is a lot better but D still is not quite like stock. I'm seriously considering the Euro Sport flash just to see since on my car the US sport flash seems a bit sensitive



Hope that helps a little.

That JPEG is from post #1 of this thread on N54Tech.com:
For those who don't like the Alpina B3 trans flash

Ironically, the OP of the thread referenced above got the Sport AT misinformation from you in post #7 of the same thread...

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.

I concur, flashing the TCU with software meant for an N52 application is not advisable.
