Re-mapping the latest BMW ECU software

Here's a question for the mappers out there.

I've heard that the new BMW ECU's cannot be re-mapped legally. This, I think would apply to the 123d at the moment.

I think you can hack the existing software which is totally illegal but there is no easy workaround....

There is no tuning solution I know of that will succesfully work on the 123d and 120d 177bhp engines.

Legally or illegally I dont know of any tuning company who can remap the later EDC17 ECU.

Due to the "legal" team of BMW getting rather "heavy handed" I wouldnt even like to discuss this topic on a open forum

Dr crap, you can tune them, just not via a re-map of the ECU. A tuning box can be purchased then fitted and will give you a good horsepower and torque gains similar to that of a re-map

How can it be illegal to modify the cars software?

I know that this can be the case in terms of intellectual property with computer software, but it's not as if there is a EULA (end user license agreement) for the bmw code .... or is there?

In any event, the person who developed the idrive software has nothing to protect. I don't understand how something so simple can be so slow. Why don't they stick a dual core chip in it?

The new BMW ECU is encrypted. It can be 'hacked' using the official BMW software but this is an illegal use of their product.I don't think there is a third party workaround. So the issue is the use of BMW software in an illegal way. You can do anything with the codes on the ECU, its just a question of accessing them

Ah .. so the only way to hack the ECU is to use BMW software against the terms of it's EULA?

It's not very illegal though is it?

The question is how are they doing it, there's one thing re-mapping a car and accepting the warranty issues, there's another running a map that has been made illegally.

Also, i seriously doubt the re-map on the new ECU will be 'invisible'

I would'nt want to be an early adopter of this mod

CAA don't do the remap themselves. Bit dangerous to say where/how it is done as BMW these days like to pursue engine tuners through the legal system... however, the CAA remap is effectively the same map as that offered by some other European-based companies. Of all the cars I know about that have had this remap (admittedly not many - eight cars I know of) there have been no issues/reliability concerns. One such car has covered over 10k miles on the remap.

The Superchips offering is not a remap - it is an external tuning box that connects to the ECU to modify fuelling and boost. It is £599 on their website. As such, it is a different product to the CAA offering, and offers only a moderate increase in power (hence its reasonable pricing in comparison).

The Procede / Xede / JuiceBox offerings from the States are much the same, with varying levels of power and adjustability, price dependent.

Oh... I didn't know that, I just saw that they are offering it on their web page, and presumed it's a chip, not a tuning box. Thanks for the clarification.

But the gains are quite decent - 343 hp and 490 NM (they started with 305 hp and 419NM).

Probably. And the fact that there are almost certainly no more than two companies that can actually remap the ECU (that's not to say there are only two companies offering a remap though - just that the work is outsourced to probably only two companies)
