8HP76 swap.

[Thraxbert]

No way a 51 can match that. Only the 76 can do that.

No. All ZF 8hp transmissions shift in ~200ms. The 76 is nothing special. Have fun wasting your time for nothing, little boy.

Then why does xhp advertise dct level shifting speeds for the 8hp76 maps while the 51 maps don't mention that.

DCT shifts at ~80ms

But for me honestly to get a trans built in ozzieland costs 15k not including install.

This option with xHP and the 76 wont be more the 6k AUD.

This thread is going pretty much how I thought it would.

I had a little hope it wouldnt go this way...

It's going towards the direction i explicitly said i didnt give a F about.

Oh well.

I will update this thread with my progress if anyone cares to hear...

I have bought the transmission!!

Workin with xHP to get a custom map and then will do the install myself.

If i had a hoist the job would be easier...fuck me dead.

Nothing a few beers wont fix ?

It's the internet. It will naturally go opposite of what you ask. Why ask if you were just going to attempt anyways.

It fits. TCUs are a bitch.

jesus fuck.....yea it is.

jesus fuck.....yea it is.

Goes through the whole list of tools but the tool he really needs are some nail clippers.

Looks pretty straight forward ?. Pcb boards and soldering is my work background so it's nothing.

Tbh the 76 and the 51 are both gen 3 transmissions so there is no need to physically mess with the TCM or the valvebody for that matter. As long as xHP can create the custom code successfully for my vehicle itll be fine.

If they can't then im stuck ???.

Xhp does hexadecimal?

If they don't, you can flash the S58 M3 CSL TCU software, or any of S58 car that has an HP76 via E-SYS. It'll probably work fine.

You don't need to touch the mechatronics unit PCB to install it onto another BMW. It's quite literally plug-and-play in terms of installation, unless you're going with an external TCU like the HTG/TurboLamik/Maxx.

There is a chance you might need to interface with the TCU directly through the standard milspec port, but that's only for removing the immobilizer, and IIRC it can be done through the car VIA OBD.

In Europe there are plenty gen 1 b58 which swapped the 8hp50 for the 8hp70 since you find the 70/75/76 in diesels over here(more torque). Afaik it was pretty straight forward, for going from 50 to 70 you need the 70 flywheel and you need to modify the downpipe bracket. Im very interested in what you are doing since I can get a 76 for cheap here in Europe, let us know how it is going on

edit: some more info here on the 70 swap

Thank god for not having to bypass the TCU to use a standalone.

 

[whoop_ass]

keep us updated i might also be going this route

Or here’s a crazy idea… just build the 8HP51 that’s already sitting inside the car, instead of giving yourself an aneurysm with TCU and coding headaches.

Any updates on the project?
