wait, how do I enable this?
@ForaFrank - how do I code this in?

@ForaFrank Cable came and managed to get the road sign recognition working it displays the road signs on the top left of the cluster.

Im also going to play around with the original camera and see if the lane follow can be turned on with keeping the original hardware, will report back.

Which cable did you get and how did you code it? can you share a step by step guide for people that are new to this?

@ameeno Hello! You're asking about a process called "variant coding," which is essentially venturing into the car's digital back rooms. As @dan_UK discovered, some features like LFA and road sign recognition are present in the hardware but were deactivated in the software from the factory. By "coding," he was able to tell the car's main computer to turn those features on.

This isn't a setting you'll find in the regular user menu. It requires a specific diagnostic cable and specialized software to connect to the car's control units and rewrite parts of their configuration. Since it involves altering the car's factory programming, it's a project best approached with a bit of research and a steady hand. I see you've already asked the pioneer of this thread for a step-by-step guide, which is the perfect next step, as the hands-on details are best learned from those who have successfully made the journey.

@ForaFrank this is great where can I buy a cable, and what'sIit called? what should I google to find the right cable and software?

Hi everyone,

I'm looking for someone to help me enable Lane Following Assist (LFA) and road sign recognition on my 2020 Ioniq Premium EV.

I was inspired by dan_uk's successful retrofit thread here.

I'm based in West London and am happy to travel to someone who has the necessary coding tools and expertise. It seems like it might be a straightforward coding job for someone with the right equipment.

Could anyone in the area be able to help?

Thanks in advance!

Hi @dan_UK, this is very helpful info.

I may need to visit you, but I'd prefer to do it remotely. Could you share what settings I need to configure in the software and what variant codes I need to put in? From what I have read up on variant coding, you need to know the actual hexadecimal values to code, as well as which modules to write to.

I'm happy to jump on WhatsApp or Zoom with you if it's easier to discuss. Once I complete this project, I am happy to document everything and do a full write-up with a proper guide.

Thanks in advance.

(Does one need to buy a licence for the software you linked?)

Hey @dan_UK thanks for the tips. I managed to code it in today, both the speed thingy and LFA. It was actually just a few button taps using the thinkdiag Bluetooth dongle connected to the
15.MFC (Multi Function Camera)

Under special functions, click variant coding and then enable

ISLW Option (None): Intelligent Speed Limit Warning/Information. -> Enable

That gives you speeds.

And LFA Lane following assist to give you that option.

It's basically a simple on/off switch and so easy with the correct device!

Not sure I actually like the LFA now that I have it.

Is there a quick way to turn it on/off, as I like SCC at lower speeds but only want LFA on at motorways.

 

[ameeno]

Yes I did it via thinkdiag app. After loading up your VIN and going through the options you go to MFC (Multi function Camera) -> special functions -> variant coding -> and enable ISLW and LFA. And then save after.

All very easy and straightforward. Even enables ISLW on my friends Kia Niro.

I can't figure out how to enable HDA though. But with LFA it's basically self driving on motorways.

 

[ameeno]

I used a standard Thinkdiag to adjust the forward camera on my Kia. Look for the setting called FCA (Forward Camera), not MFC. It was an easy change.

The Thinkdiag worked because it can do ECU coding. Be aware it has a £100 annual subscription, but you could potentially buy one, use it, and return it to get the fix done for free.

Yea I couldn't enable HDA either and have not yet figured out why, I have a sat nav head unit and would love proper HDA, but not sure how to get it going.
