The 2020 370z needs a DCT

-ZS-Carpenter

If there is still a slot open I'm in. Shoulders are to fvcked for rowing gears, not interested in the new Z and don't want to trade for an auto. I'll be the guinea pig on an NA car for a bit

How many miles is the cutoff when shopping for a transmission? I'll be NA for a couple more years so no worries about overpowering it for a while.

Its totally open, it never actually ended up going into production. The company that made the transmission controller that was used in Sebs car for R&D lead us on for a very long time but ultimately never did produce any more TCMs and has pretty much fallen off the face of the earth.

This means that, for the foreseeable future, it is not possible to provide any type of assistance or support for wiring and controlling the transmission. I can produce and sell the parts that allow for a physical bolt-in solution for the transmission. But wiring and controlling that transmission and shifter solutions etc, will all be dependent on the individual installer, who will have to use one of the other standalone TCMs available for these transmissions. This will take a lot of research on the matter, which is honestly going to be quite a bit out of the scope for 90% of DIYers. There is a whole lot to have to learn about to do it, and its a real shame for any human to invest that sort of time into it learning it and figuring it all out, to merely do it just once.

The hours that go into it will also make it unviable for most customers who would consider having a shop figure it all out for them, unless such shop was willing to invest their own time for the sake of learning it and supporting it. But if someone was going to be paying hourly rate for a shop to learn it from scratch and do it, we are talking about probably 10K + in time.

So for these reasons, I have sorta let it sit on the backburner not really sure if its worth producing a batch of them or not.

Andre_ems on IG. Tuner in S. FL. is DCT swap and shifting. HR S14. Has videos of it shifting. Might want to hit him up.

LOL sorry for the misunderstanding but we have already completed the swap with a running and driving twin turbo 370z long ago. Andre learned of the DCT swaps from my facebook posts about it.

You may find this interesting....

After I posted the video where I was controlling the G37 gauges via the CAN bus, Daniel from SU2 Performance in Olsztynek, Poland asked for some CAN bus reverse engineering help for his TWIN TURBO 370 with the ZF8HP!!!

He sent me some CAN bus logs and in a few hours he had what he needed.

Here is a video showing the car from their youtube channel, but is isn't in English:


Here is a pic from under the car:


phunk is correct... that is the best transmission for the 370z!

Not good. Hate it that the TCM folks ghosted everyone.

phunk

Well just the one company anyway. The main player for standalone TCM for the DCT is HTG and they are still around and very active. But its still a pretty complex wiring project and I dont know if the swap is really going to be something the community is after if there is nobody providing and wiring package for it.

Probably will be easier and cheaper to swap in the new z34.5 9at assuming it proves to be decent (fingers crossed it is). Bell housing adapter, custom trans crossmember, and new driveshaft. Nissan tcu electronics should be easier to work out.

Nobody wants a slush box. DCT, YES.

-ZS-Carpenter

I don't see how people think a couple extra gears will make much if any difference. 7, 9 whatever, a slush box is a slush box. I'd rather go through the growing pains on this and have something great than trade for an auto

The 9G Tronic, if anything like the ZF8, would be a massive jump up both in shifting behavior and torque capacity from my current 7AT. It'd most likely still need an adapter plate, TCU, mounting, and new driveshaft though, plus will be into next year before we can get a hold of the new Jatco designed one from the new Z.
Would rather have a DCT at that point, plus actually have one just sitting in my garage.

Is there not enough interest for any tuners to help pioneer with HTG instead?
Their FB group and support has improved a massive amount over just the last few months, to the point where I'd just be concerned about wiring and not software control.

I think that the incentive is low for platform specific tuners to get into it. They don’t have much to gain or money to make for all the time they will invest. Seb is in the perfect position because he’s at a good Z shop, is a tuner himself, qualified/experienced with technical wiring, and even has a personal interest for his own car. It’s easy to imagine though that the idea of starting again from scratch now only to switch TCMs, at great expensive of time of money, is probably discouraging. He has never implied that he will not, it’s just that no discussion has taken place over this, because there has been no defined moment where we gave up on the original TCM supplier. Last contact with them was more about how it’s coming, but alas it never comes. What happens is you wait and wait and wait, and then you just stop thinking or talking about it.

The DCT swap community is full of overall support for swapping the trans into any vehicle, and then it’s up to the user/installer to take any additional platform specific steps. I see this as a generally more likely and viable business strategy for companies in the DCT swap scene over platform specific shops.

I did fire off an email today to one of the more well put together DCT swap shops in Europe to see how complete of a wiring package they offer these days. If not by now, then at some point somebody is going to have as plug and play of a universal kit you could viably have.. and then someone like myself (or preferably Seb haha) can supplement it with the necessary additions for the platform that we need.

Awesome car and a cool dude
You can tell he's passionate about modding cars and he's definitely caught the bug for life now. (Edit: probably should've worded that last part differently for post 2019 society, but whatever...)
