Improve Driving Assistant Plus by Updating ECUs?

BrBull · 02-17-2021, 08:07 AM

I have the Driving Assistant Plus.

I am wondering If I update those ECUs which are being used for this assistant; will it improve it?

For example KAFAS4, RS and so on?

Thanks!

Are you asking if a software update will improve DA+? If so, yes it can depending on how old your iStep version is installed on car.

If you're asking if upgrading modules is an option, the short answer is it will be cheaper to buy a new 2021 G30.

From what I've seen of the new system (I haven't driven a MY2021 with it yet) it looks more evolutionary than revolutionary. I wouldn't buy a MY2021 just for it ahead of the platform refresh. Such as the next major evolution launching on the 7-Series later this year called "Motorway Assistant".

I wonder if that will come to the 5-Series ahead of the platform refresh or not...

BMW still has a lot of work to do on the tech front before it makes sense to chase their evolutions IMHO.

Yes I was asking for flashing ECUs with latest iStep version. My iStep is 17-03-509 which is old.

Which ECU should I flash? KAFAS4, RS, FRR2 any other?

Thanks!

I drove a 21 with the full driver assistant and hands free driving for about 1.5wks and it is a VAST improvement over what I have in my 17. Both systems are good at traffic jams but the 21 with the 3 cameras performed great cruising in the freeway. My car got istep'd and it changed DA a bit, haven't had the chance to use it to see how much of an improvement it is though.

the old DA+ is out of service, only the new DA Prof get new Updates. Have a G20 (M340i) and a G30 (M550i) in my house, there are significant differences between the systems. The DA Prof is more "Autopilot", more autonomic driving as the older system(DA+). And, the old system is not upgradeable...

The old system is upgradable via dealer updates. It is also still shipping on the X3 in MY2021 at least...

So I won’t say it is a complete dead end. But obviously the new system has improvements.

I’ll update ECUs and compare results between 2017/03 and latest one.

Be sure to do a full programming of all modules.

Please keep us posted! I had exactly the same question, having just bought a 2017 m550i with DA+

All ECUs updated to the latests iStep. DAP has been improved. Not a big improvement but more accurate.

I got in November S15A-20-11-534.
Yes, it is right, some improvements for the DA+, but do not extpect too much. The car no longer oscillates between the lines.
my car ist a 03-2020

The-Traveler · 01-10-2022, 10:59 PM

For what it's worth I have 21-07 and it's been great! 2018 530e. Drove 4,400km from Vancouver BC to Toronto ON through the states, and the car did most of the highway driving itself. I just held my hand there to reassure it, lol.

Funny enough it was oscillating a bit in Ontario, but I felt that the highways here are slightly wider than the US ones. Those were pretty great.

Where do I find the istep version? I had coded complete hands off and am hesitant to update my software for fear of losing that coding.
