That E30 though :party:

Nice work Harald; impressive to see it working, but I guess that's what doing things properly gets you. Eager to see that in "fast" mode.

P.S. Got any more details on that E30?

That e30 has 840awhp and runs a stock dct with upgraded clutches:)

I did a little test with higher boost and quicker gear changes yesterday.
I didnt have to room to stay in it for several gears ør high rpm but it's fast.. 1.9 bar boost.

2nd to 5th gear

Awesome

Looks awsome congrats!!! Is there anyway i could buy or have made a controller for the dct gearbox like yours?
Thanks.

Maxx ECU will have a standalone DCT ECU soon. This one is designed to PnP into a BMW BMW E90/E92 DCT

Maxx ECU also has an ECU that will control the K24 now. Our project will get a Maxx ECU. Cost more than Harald's system but easier.

That's awesome! I'm running a maxxecu race right now... So if I ever decide to go K24 (which I really want to), this is a nice incentive.

A local bike shop that I work with uses the MAXX ECU on Busa's. We are planning a build for a 750whp EFR Busa build this winter using one. I am hoping to get one into my personal miata either in the winter or spring. It looks like a fun ECU to play with an has some decent features built out of the box that make it cost competitive.

Jesus man, that's fast. Really fucking fast. Can't wait for some good daytime videos, great work!

These gearboxes will get stuffed into a lot of cars very soon. a PNP solution is much easier, but when i started this there was really no options for me. And the M4 gearbox is still not controlled by maxx.
I am thinking of upgrading my cars ECU, but i will probably wait until there is a well proven solution that also controls my M4 DCT :)
We have several gearboxes now and plan on running these in rx7s, and cosmos as well.

For a k24 with high revs the m3 gearbox will be really nice.

Also.. my friend with a turbo LS chevy nova has been running his DCT box with stock clutches and around 700 whp for a couple of months now with no issues even launching with 325 wide R888s. so they should be plenty strong for our small cars :D

What about speed signal? Does the DCT box have a sensor or from where do you get a speed signal?

No speed signal from the transmission as the newer bmws use the abs sensors.
My car has never had ABS, but i have retrofitted a couple of hall effect sensors for wheelspeed (senses the wheelbolts passing by) and i will be running that signal from the rear into a dakota digital unit that translates and calibrates the signal to a signal a NB cluster can use, i then will install a NB cluster with custom gauge faces etc in my car to get everything working, and get a 300kph speedo and 9k rpm tacho i want

Not too difficult to put a hall sensor or input yoke of diff. Simple square wave signal. Converting tone ring signal into required format for ECU can be more difficult.

The V8 miata guys use a dakota digital unit that can translate my existing speed signal to something the NB cluster can understand.

i already have 2 hall effect sensors going to my ecu for tractioncontrol.

Great to see,

Ive now started on my build now. Ive been using the RX7 gearbox on my K20 turbo RX7 but the gearbox syncros always take a smashing.
MAXXECU and M3 DCT box going on mine next.
Look forward to playing with it. 1 worry is the width of the box. not allot of room for an exhaust now.
My exhaust fits down the other side of the trans tunnel... ohh well might be a bonnet exit next haha.


Keep up the good work

width and height is an issue if putting it in a mx5 chassis. you will need to widen the tunnel to fit a exhaust past the transmission, and probably raise the engine a little bit. but its a freakin cool swap when its done :D

A friend of mine is swapping a DCT onto a 4Liter jaguar inline 6, supercharged and turbocharged and north of 1000whp. in a old opel blitz truck that weighs about the same as 3.5 mx5s and its still within the limits of the gearbox according to those that have tested big power :D

Holy moly. My m3 is DCT and this is a fucking win. Impressive fab work and a hell of an idea.

If parts were made available for sale, would there be any interest? i can make and supply 7075t6 billet flywheel adapter with ss2541 Splined adapter for DCT transmissions. Will bolt on to a miata 1.8 flywheel and mate to a DCT perfectly.
Engine mounts to raise the engine the correct amount could also be made, and probably the trans mount. custom driveshaft can be made but shipping would be expensive from norway.
A kmiata 6speed e46 bmw trans plate would have to be sourced in the US(no point in shipping it back and forth).

I would be interested if parts of a kit would be available separately.
I live in Turkey and shipping + customs is a major ordeal for me.
I can source the transmission and make the adapter plate and the driveshaft. What's difficult is the sexy bits - controller, paddle assembly, etc.

BTW, I am following your project very closely.
If there was a way to combine our systems, the end result would be nothing short of fantastic.
