Wanted to write a quick post regarding the project that I'm considering/probably going to do tomorrow. We got ahold of a salvaged 135I with a good trans on it.

I was planning on replacing my solenoids in my Car tomorrow anyway & figured I'd pull the valve body out of the 135I & place it in mine. From everything I see everything would work, just not sure how the car & the DME would react the GKE215 TCU.

I know the module is tuned for MUCH more horsepower, but everyone flashes the Alpina flash to the x35I's with great results & the alpina is 60HP higher than the standard 35I variant.

As mentioned, this is purely for testing purposes to see if it's possible for a 330I to run alpina flash with a 335I valvebody TCU.

Let me know your input....

Interesting project, Is this the ZF 6HP19TU? I think the ZF 6HP19TU was the same box as the ZF 6HP19 with an upgraded megastronics units and a few extra clutch plates. TCU was upgraded to handle the additional code. I thought some of the 335 cars had an even larger box ZF 6HP26.

In any case, you are probably going to have a hard time finding a calibration file that works with your high revving N52.

Off topic, I have a few things going on in my life right now and I need to consider a newer car so I test drove a N55 based car the other day. Great low end torque but it seemed to fall on it's face at 6,000 RPM. Totally disappointed. In general, I loved the car but I can't see my self buying a car that is less fun to drive than my E85.

Both transmissions are the GA6HP19Z. There are ALOT of zb's for the GKE215 in the v59 datens. Roughly 20 or so, Im going to dig in & see which ones fit.

I've driven quite a few N55's and installed Jb4's on 6 or so of them now. They are fun cars & I love the torque, if I was in a position to get a newer car I'd definitely snatch a 435I & throw a Jb4 on it.

Just got through sorting through some of the GKE215 ZB's and there are some that belong to 330I N52's. At least I know that if the results of the Alpina flash arent worthwhile or any of the other files, I have a ZB I can flash to instead of switching the valvebody back over.....

By the way, which TCU does your E85 have? It looks like theirs a Z4 EGS sport flash.

I have the 6HP19.

It's the first generation of ZF 6 speeds. Not the TU or technical upgrade used after 2007+ in the E90.

I'm not sure about the fun factor with the N54. I expected more from a e89 335si. The build up from mid RPMs was great and when it gets to 6,000 RPMs it just leaves you wanting.

Yes I know it's pulls massive power over the N52 but the fun just seems to end early.

I'm not there yet. If I could throw a few grand at my E85 and freshen it up for a few more years I will keep it. Just won't be able to do my own wrenching anymore.

Yes, the 2006 330i and 325i use the MsV70.

You can run the updated 03/07 mechatronic on the older 335i, 330i, and 325i.
Once swapped, these cars will accept the Alpina Flash.

I wonder how those programs will work for an E85?

I know wrong forum, but we get more N52 stuff done here.

[hassmaschine]

I don't see why not. However, I think the Z4 is Can11h, not BN2000, so you would have to figure out how to enable Can11h for it to work on the Z4 (this is a simple byte setting on the DME, but finding that byte on the TCU could be difficult).

IIRC these things use an MPC500 CPU - if anyone has a complete dump of one, I'd love to see it. I kind of want to do a disassembly of one.

That's why I was asking which module your EGS uses. Pretty sure it's GKE211 like mine. That's the only EGS I see in the e85 Daten folder.

There is a Z4 EGS sport flash in the GKE215 folder though, must be what they use on the alpina roadster.

Update on the project, we got the 135 valve body out & got the new solenoids put in. I ordered a new adaptor seal & pressure seals to put in when I have my valve body out. Once they come in, we'll complete the swap & do the flash & I'll update the results.

[hassmaschine]

if you have the old TCU, would you be willing to send it to me?

I sure will. Once I complete testing with the new one & make sure all is ok. The N52 file for GKE215 that I'm relying on as a backup if the alpina files don't work right belongs to a Euro 330I. I have to dig deeper to see what ECU it uses.

But after the swap, if all works well, the old TCU is yours.

Is that for a E85 or E89? I'm pretty sure the E89 version of the N52 uses the MSV80 but I really don't know if that makes a difference. More research.

Getting really interesting.

[hassmaschine]

it is MSV70 in 2006. MSV80 wasn't until the 2007 328i.

That's what I have to dig in to. They didn't discontinue the 330I in 2006 for the Euro version.

Cool. I know they are hard to come buy for experimentation because it's part of the transmission. It should be flashable via BDM too, but that would be difficult without a lot of work.

I hear ya. The crazy thing is that today I got the "transmission temp" emblem (red gear with thermo in the center) today while sitting at a redlight, car had been running for 3+ hours straight. Let it cool for a few hours & all seemed well, but when I scanned it had zero codes?

It looks like I'm going to go a step further & order all new seals & o rings for my trans while I do this project. Probably going the sonnax zip kit route. With that said, it may be mid next week before I get the parts & can get a lift vacant to use for the entire day.
