Go reread you'll see he's using a DKG ecu, that ecm requires you to strip all the BMW controls from the trans and it controls the selenoids directly. The functionality you're describing isn't simple, it assumes there is something handling the clutch to clutch shift timing and actual shifting of the gears. The DKG is about as simple and cheap as it gets and it's neither cheap or simple.
Good catch on the ecu, and thanks for the input It seems like DKG's webshop is not currently offering products which is unfortunate. Still if anyone out there has a schematic of the inputs to the transmission(and range of allowable inputs would be especially helpful) it would drastically help with development of diy controllers. Thanks again for the response.

They never have had a way to order online, just have to email them, it was just over a grand for the ecm.
The info you're asking for only exist from ZF, the oem interface outside of the case are most likely CAN based and not what you want to do......I'm highly suggesting not going down that rabbit hole, you'll have way more than the money invested in the DKG ECU and be playing catch up to their level of development
I am having a hard time understanding the logic behind such a robust transmission mount.
This mount is secured, via a total of 8 bolts, to the trans tunnel. The tunnel is made out of maybe 1 mm sheet metal.
Considering the strength of the attachment point, does it need to be such a strong mount?
I'm sure you have good reason, I would really appreciate if you could shed some light on this.
the reasoning behind making the trans mount solid is to do it once, and never have it fail. the trans is HEAVY, and a lot of weght will be hanging of those mounts. so i mounted it with a backing plate inside the car and several bolts because it takes the same effort as making it with less bolts and weaker. i could probably lift the car up inverted from my mount.. but i know it will never fail
HTG is also a good option now, and probably the way i would go if i got the trans controller now. I used dkgecu as i was a very early user of the DCT trans in any car. HTG seems to be more into the buisness side and better user interface.
@hf-mx5t I'm curious where you got this splined insert? Is it something you machined?
I see a lot of these BMW DCT swap kits with bolt-in inserts like this. I'm curious if it's an "off the shelf" part, or if companies are machining them for their kits.
Just a few progress pictures of my ongoing DCT swap in a 92 miata.
Im installing a 7 speed dct box from a 2016 M4, "because i can".
It will fit the BP with a slightly modified Kmiata adapter plate, but pretty much everything else will be custom made.
it will fit in the transmission tunell, and for a 450whp street/trackday car it will be plenty strong, and have a higher top speed/lower rpm for cruising/autobahn driving(200mph miata?)
would you be interested in making a conversation kit to sell
