I can only try to rev less but it feel like a monster when it hits the red line, lol.
Looks like 325d came with 6HP19. Possibly the reason why it took the flash?

I was surprised to see the Programmed OK message.

I now have D1 D2 D3 D4 D5 and D6 in automatic D mode

I now have M1 M2 M3 M4 M5 M6 using paddles

And when I put it in manual mode I get S1 S2 S3 S4 S5 S6

The RPM dial goes into the red line 5k or so, if I floor it

My car is UK 325D e92 it was made in 2007.....

My concern is, I'm I slowly killing my gearbox.

Let me just get this straight - you used the alpina image on a 325d with a HP19 automatic transmission?

Can you send me the Alpina file? And a short description on how you flashed it? I'd like to try it on my remapped 325d.. Do you know if it disables the torquelimit on the gearbox? Right now the gearbox is limiting me to 512Nm - but I know it will take 600Nm above 3.000 just fine.

Yes no problem I will do that for you tomorrow, I'm not sure if it limit the torque it defiantly rev into red and it didn't do that before

Yozh is right, at this point there is no guarantee if it will work or not. I'll check with Robert on how much money we'd need to raise and what else he needs.

Anyone here with a shot mechatronic unit of the US 335d? Didn't hear back from the banned one yet.

What parameters are involved for limiting the torque? Does the limiter just reduce the amount of injected fuel in r, 1st and 2nd?

Some great progress here!

Are any improvements only going to work on the US 335d or would they work on my UK 330d N57?

Did Robert give any insight into what the JR/JF Flash module does or doesn't do?

Based on what he told me about the vast amount of different SW projects for the 6HP26/28, I wouldn't have too much hope that it fits directly. But if he has your version he can check. You'll need to find the sticker on top of your bell housing to give him a first indication. In order to make sure, he'll need the hex dump from your transmission.

He said he isn't aware of any proven transmission tune through OBD.

We know that it is not a flash module. It does not change the program or maps. That is per the supplier. What it appears to do is send CAN messages to "fool" the TCU. BTW, it is the same method they use for increasing engine performance. This similar to some other ECU tuners.

And from where should the unit "send" those signals? I tried the JFA unit and it's nothing you connect permanently to the car. It's just connecting it for ~ 30sec and you're done. To cut it short: It was a total disappointment and i returned it after a week. There wasn't even the slightest change in TCC or shift behaviour.

I also mailed with JFA a couple of times, but they only gave me standard "you have to wait for 300miles" and "every customer was satified until now" answers. In my opinion this box does nothing. It's all a marketing hoax.

Personal, i just like to get rid of the TCC slip in 1st and 2nd gear and maybe there is another way of achieving this, without flashing the TCU. It's just an idea, and far from well thought over, but I was thinking of tricking the TCU with CAN messages through an external tool. The TCU closes the TCC as soon as it senses a certain amount of cornering g's. Even in 2nd gear with 10 - 15mph, you just have to do a tight turn and the clutch is closed immediately, and stays closed.

What do the pros in here think about that one?

You are correct and I was sloppy in my post. The "signals" are to modify lookup settings and create a permanent change. I operates over the CANbus and really not an OBD function. The OBD plug has access to the CANbus.

I did get you right, but I'm curious where this new "lookup settings" are to be stored? Every time I do changes with NCSExpert, or flash with WinkFP I get some kind of reaction from the car e.g. fault codes in CIC, a "gong" from the dashboard etc. Just the normal behaviour when one of the units goes Off-/Online from CAN. But nothing like that happens during the install procedure of the JFA unit. For me it's hard to believe, that this JF blackbox does anything more then possibly resetting adpations.

The gearbox (hp19) is rated at 400Nm. If the gearbox "sees" more than 500Nm it asks the ecu to limit the output to 500nm. This is for all gears, and should not be confused with the gear dependant maps in the ecu.

The ecu calculates the injected amount, the railpressure, the SOI etc. in order to give 500nm max. Only way to get more than 500nm from it is to cheat with the torque calculations - or the injecor scalings. The latter is IMHO a big NOGO as it will also offset the lambda calculations big time. The downside of messing with the torque model is that gear changes will be worse as the gearbox really doesn't know the actual amount of torque produced. This is also why I do not recommend tuningboxes at all.

I have a suspicion.. If the engine would make power 'till 5.500 it would not change gears until this. The only reason it changes gears so late is because the engine actually makes power untill ~4800 rpm - then when the power drops the engine switches gears. The reason for this is that the alpina file is made for a petrol engine, not a diesel. I think that 0-60 times actually is slower now, since you "overrev" it.

So. if the Alpina files works in a 325d, I *think* it would be beneficial to "control" the shiftpoints using the gear dependant torque limiters - this way we will not overrev the engine, but we can design shift points for each gear. ..When going WOT.

Please let me know if you have the alpina file, then I'll try it on my own 325d.

Does the Alpina flash make the shift speeds faster on your 325d? Will it work on a UK 335D?

Would love to get it on my car.

I want to retract the statement above, as I believe their description of what they are doing is misleading. I did a little research and now believe they are utilizing the following:

SAE J2178-3 (Titled: Frame IDs for Single Byte Forms of Headers) defines the message assignments for the single byte format and the one byte form of the consolidated header format. SAE J2178-4 (Titled: Message Definition for Three-Byte Headers) defines the message assignments for the three byte form of the consolidated header format.

I did a quick search for the Alpina SW version and the HW version associated with it. (edit: I looked in GKE215.dat)

Alpina SW is: 7615835, the related HW version is: 7591971

..Now I did the same with my 325d. SW is: 7603529 and the related HW is: 7591971

So my car has the same hardware as the Alpina, I'm getting hopeful now..

M17Ull: What SW/HW versions did you have before the Alpina flash?

Original version was 7576498. This was the original from 2007. This would not update using comfort mode.

So I checked with ISTA/P the version I should have used when updating was 7603529

I used 7615835 and the car took the update

I updated this by selecting Comfort Mode, and used the enter zusb function then the car took the update.

I've been using it for a week now, providing my foot isn't glued to the floor it doesn't red line

It shift with the driving speed (it does feel like its shifting faster)

I don't know if it works with 330D - but if winkfp doesn't complain when you flash it then it should work as long as your using comfort mode.

In D mode it does D1 D2 D3 D4 D5 D6

10 mph 1st
20 mph 2nd
30 mph 3rd
40 mph 4th
50 mph 5th
60 mph 6th

If you put it manual mode (gear stick to the left) it does S1-S5 and red lines under hard acceleration does have a S6

Paddle shift works like normal

Interesting, that is the same SW as I'm using. I did have another ori (my car is from 11/2007).

I'll try the Alpina file later on.


then on to something different. I just got a message on Facebook, a "colleague" is working on a remap for the BMW gearboxes. It was titled "Coming up!". I asked him about the possibilities for a ZF6HP19 remap and he said it is in the works, but he needs a testmule for the final testing.

He is a remapper doing mainly Peugeot/Citroën cars, but not limited to them. He has made his own remapping software/hardware (Lionheart/FlasherTHP) so I know he is capable of making things work.

I'm waiting for more information.
