MKV Supra G8x LCI Steering Wheel Retrofit

[nanaisu]

I can make a wheel heated and have the revenant plugs needed, the coding would be on the customer. In terms of distance adjustment I’ve tried every conceivable combination of Oem bmw button combo’s, none will work with the gap adjustment. Its so minor of an issue most people I’ve spoken too have it to set to the shortest gap anyway, I’ve yet to meet someone who actively changes the gap distance they use on a high enough basis to make it worth the possible investment of making it somehow function.

Hi, nice to meet you! I'm one of the people who actively adjust that based on if I'm doing long road trips, if I'm driving in town, or if I'm driving to work.

Perhaps the correct path forward isn't brute forcing it and hoping one button option works... Rather we should take a more scientific driven approach. We can observe what signals the OEM buttons sends to whatever module to adjust the distance, we can observe what signals the aftermarkets send. Using this information, put a SBC in between the aftermarket buttons and the connectors, write a small program that listens and translates the sent message to the expected message.

If you don't want to supply the SPCs, that's fine. You could always work with whoever manufacturers the electronics for the wheels and let them know you need the two button signals remapped and give them the required information. i.e. what signals need to be sent.

Alternatively, add a new device someplace on the can-bus/k-bus/i-bus/whatever bus that listens for whatever signal the aftermarkets send and send the right OEM signal.

I don't expect you to be super into finding a solution as it's more work for you and people are buying it as is. But I'm not a fan of "just accept it doesn't work" and I suspect most people aren't as this isn't the first time the questions been asked. I'll put it into perspective. You could earn a customer, or several here and give your business an edge over competitors by not half-assing it and coming up with a solution.

Again, this coming from a potential customer - People care about retaining all OEM functionality. Leaving 2 buttons there with no functionality that should work but don't is half assing it. If you care about gaining customers here, don't half ass it.

Consulting the BMW crowd is also an option. Though, I suspect they'll tell you much of the same. They're smart folks, we're playing on their platform and I'm sure this is something they've messed around with before.

This should be a good read too for getting started into figuring it out - https://archive.org/details/thecarhackershandbook

Good luck, hope you don't disappoint.

I don't "half ass" my work, and the hundreds of steering wheels I have sold to people on this forum speak to that. I have done more innovation, research, and testing than any other vendor making steering wheels for this platform and have sold more steering wheels than any of the vendors out there combined.

No one is brute forcing anything, there are only a handful of oem bmw button combinations that fit for the g series wheels and I have tried and tested each one of them individually to see if that can solve the issue of the gap adjustment not working, they don't. I also have done hundreds of BMW specific wheels and very familiar with what it takes to make those buttons work, supra's are not my only market. The Supra uses F series technology, the G series uses a different canbus system and entirely different harness. We are lucky that any of these buttons even work as theoretically they should not. You are right, with enough time and money it can definitely be made to work, would it be doable without serious coding, harness changes, wiring work and modification to the supra canbus system and harness, no it would not. It would not be realistic or even viable to do from a practicalality standpoint.

While I do appreciate your input, as one of the few people that use the gap adjustment, from a business perspective the 1 in 50 people that will want a g series wheel, have an auto with ACC, and need to use their gap adjustment, it does not make sense to invest the time into R&D to make it a viable option, and again if I was to make it work, I guarantee you would also void the warranty by doing what it took to make it work and be extremely burdensome with installation and coding, opening up a whole new can of worms and possible issues. If you really want to retain gap adjustment, I would advise you look at the thousands of Supra core wheels I do, they are great and retain all oem functionality. In Terms of heating, I am happy to supply wheels with a built in heating element, that is not an issue at all.

It is much easier to say, just do it, provide it, make it, until you actually have to do it. Modifying cars is not a one way street, there are drawbacks to almost any mod you will do, it is very rare to find a part that will function like oem, have 0 drawbacks, and still meet financial constraints in a market that is extremely tight. I've spent tens of thousands out of pocket on R&D for this platform, for much of it be stolen months, if not weeks after I release it publically, or copied poorly, or maybe a vendor who reaches out to be a dealer, gets access to proprietary information, and immediately goes and steals media and sells it as their own product. I would love to be able to make all these issues go away, but it just isn't feasible, especially for such a small market share that the cost of making this issue go away, would exceed any possible profits I could make, these wheels are not cheap, these modifications are not cheap, when I make between 2-400 per steering wheel, even selling a dozen with this fix would not come even close to the cost of developing a viable solution.

In short, while I appreciate where you are coming from, I don't appreciate you coming onto here and claiming I am half assing anything, as many can attest here, I am one of the original few on this forum, I have had multiple supra's, created and developed hundreds of parts for this platform, and have constantly pushed the envelope of what is possible. As much as I would love to earn you are a customer, at the end of the day you can not make everyone happy, and I have learned that over many years. So if someone else can figure it out and make it happen, more power to them, I have tried, and at current state can not provide a viable solution, simple as that.

And as a future disclaimer, if you are going to ask a manufacturer to develop something for you or a small group, it will help not to insult said company with disparaging remarks and condescending comments such "Hope you don't dissapoint".

Well a few months ago I had an OEM G8x LCI wheel turned into a supra wheel and think it came out amazing! So far I have done a handful more of these and it really is a great looking swap! Been meaning to post this sooner but life has been busy as some of you know I started law school, it has been a hell of a journey so far and time has been hard to come by, but still very much active in our groups and in this community!

Going to be running some aggressive Black Friday/ Veterans Day/ Thanksgiving sales over the next few weeks and a lot of great deals on in stock stuff. In the mean time check this out, I love it. Like with all G series swaps, you risk loosing your gap adjustment for ACC, but from personal experience and dozens of customers, it is not a big deal, 99% of people have it set to the shortest anyway. As always, whenever you have any questions or to place an order you can reach out through here or my website (berktuning.com).

Nice wheel. Of course the ACC distance set is a moot point for the manual cars.

i'll definitely buy a steering wheel from you Phillip.

Thank you for the texts back and forth, as well as the kind words for my little guy. I can’t wait to finally get rid of the BMW “Sport” wheel, one of the few things I’ve lived with since my “M” was totaled and the wheel gone. Funny thing, it was the F series, lol. Can’t wait for you to finish these and glad I ordered asap.
Keep up the awesome work, appreciate you.

When we are talking about gap adjustment, we are talking about the adaptive cruise control gap adjustment?

Does that mean that steering had no drawback for a manual car?

 

[Dven11]

Bump for Phillip! Great communication and kept me updated on my order. I went with carbon fiber top, carbon fiber flat bottom, and alcantara sides with matching air bag. I love the wheel, and it's a huge upgrade compared to the stock wheel.

PS I went back to matte cf paddle shifters to tone it down.

besides the error codes, no, you will loose no function. This mod works better in that sense for manuals.

Thank you for the kinds words, it was a pleasure working together!

Could you be a little less of an ass yourself with those comments? You are talking about someone that always does his best to accomodate and help anyone that needs a special steering wheel for their Supra. And he has been doing it for much longer than you have been in the forum.
So grow up and learn to be a little more professional on your comments even if you dont agree with the other person!

My question on all of these, which I don't think any of the modders can adequately answer without a lot of expensive testing, is how safe is that airbag after having a custom cover with a plastic badge sewn onto it?

Airbags are, at the best of times, a carefully controlled explosion next to your head designed to inflate a bag that's safe for your face to impact into. If you attempt to contain that explosion in ANY way, it will turn what's containing it into a grenade. If the plastic beauty cover of the airbag doesn't fail at the built-in weak points which allow flaps of the material to get out of the way of the airbag in a controlled way, that airbag cover is going to break apart in an uncontrolled way, and it will send fragments of plastic at high speed into your eyeballs.

This isn't even easy for huge corporations to get right all of the time, ask Takata. What are the odds these cottage industry guys modifying airbags are going to get it right at all?

Hey, very valid question! And one that I have had tested already a handful of times inadvertently, So these airbag covers do not go over the OEM cover, as you said that would inherently hinder the airbag and result in unexpected possible consequences, instead, I provide replacement airbag covers that are wrapped in leather instead of the faux vinyl/ rubber toyota uses. This is still an oem airbag cover that has an extremely thin layer of leather and an OEM toyota badge installed the same way you would find on the standard airbag cover. For the LCI wheel in particular, the OE bmw bag that comes with it is leather wrapped as standard. For the supra airbags I provide a leather airbag cover, it functions the exact same way. Some vendors/ manufacturers, do provide overlays, or I have even seen Carbon airbag covers, this is extremely dangerous, and as a law students, boggles my mind as it opens people up to unthinkable levels of product liability. This is why I use OEM Cores + oem airbag covers.

[PRMANManman]

Very interested in your black Friday deals for the LCI wheel.

 

[LanceW]

Can vouch for the quality of the airbag cover. I questioned it as well when I was ordering. Looking at them from the inside there is no difference that I could see. Looks like an OE cover, just better. Has all the scoring? for the breakaway that the factory one has.

thank you lance! yes it is just an oem cover recovered in an extremely thin layer of leather with stitching, and the emblem is just an oem one painted if so optioned!
