Csl ecu

[The Gorilla]

Hi,

Its not quite as simple as Cantfind1 makes it out.

If you obtain any S54 ECU without the keys or EWS
to that ECU then you will have to have the ECU
reflashed.

BMW can supply replacemnet keys around 175.00
each and then you have to sort out your EWS if
you want the Car on the 'Key'.

Loading on the CSL Files to a non CSL S54 ECU will
not be free unless you know somebody and then when
its that's all done what do you have and what was the
real costs?

I would source a ''theif'' kit ie] CSL S54 ECU/EWS/KEYS.

Primate being helpful.

Regards,

The Gorilla.

I have 2 keys too, is ews a separate unit? If so I guess u need to set it aside, anyone know where it is in the car?

Actually it is quite simple, you can delete the EWS from the ecu and the CSL software can be written onto the chips in the ecu. Plug it into your car and hey presto works with all your original keys, ignition barrel and alarm/immobiliser.

EWS is part of the software. Not a separate unit.

I will not go into any further details on this on an open forum.......


There are people who can do this, its not too costly. Much cheaper than buying an uncoded new CSL ecu from BMW that's for sure, then finding someone to code it to your car.

Hi,

By Passing the EWS is not some big secret.

Just one of many examples.

Writing the CSL software on to the S54 ECU can
be undertaken but add up all the costs and what
you do when it goes wrong or corrupts.

As I said if you have the oppurtunity to purchase
a CSL thief Kit, then its a no brainer.

No bypassing with modules or wires or relays required, that's a lot of hassle. Just simple modification of the software in the ecu....deletes the EWS coding. There are not many people who can do it this way though.....but if you know one of them then hey its easy....

That's actually incorrect ... EWS-3.3 (which is the one in the E46 is a separate module).

[It's the white box in the picture below - which is located near the OBD2 port behind the same panel.



Both Prime mate and Cantfind1 is sort of right and wrong on this topic ... I don't really want to get into it on here as it'll open up a can of worms on how to steal our car

Suffice to say that the 'proper' way of doing things is you'll need to code the DME for the correct EWS and the EWS will need to be authorised for the correct keys, so when it goes through the starting procedure it works as intended (i.e. key, talks via the antenna, talkes to the EWS, verifies that the key is authorised, releases starter relay, sends ISN to DME (which checks the rolling code table to make sure it's the correct EWS) for starting procedure, then the engine comes alive and we all live happily ever after ) ....

Hi,

I know some Guys in Germany who will
re-write the S54 ECU to what ever you
want.

Vanos Optimisation
EWS Delete
Dash Pod Delete
Immobilzer Delete
Set in Sport

The EWS is a type of Transponder that
makes the ''field'' when the key is
inserted in the Ignition which also has antena.

The ECU sees the signal from the correct
key, does not activate the Imob as the
signal from the EWS is complete and the
engine starts.

By defaulting the ECU to start up, the
EWS and Imob are in effect by passed.

And so on.

But the point I was making is costs.

Most charge 300/400 plus for Re-Flash
then you have to have a ECU which
Coding [ Original Poster] does not,
so another 200/300 + and where are
you ?

Most who play around with the S54 ECU
are fitting S54 engines into other cars,
E30/E36 etc but want to retain the std
loom and ECU etc.

S54 engine is a cheap power unit but the
electrics make it a little off putting to
some.

Huh? Really? How did he by-pass the EWS 3.3 rolling code that gets burned into the MSS54 DME once when you first align the two?? As far as I know that can't be done on a stock DME (which is why you always have to pair the EWS with a DME).

Also it's not the DME that sees the key it's the EWS - it has a coded table for 10 keys (4 pre-loaded from the factory), and the loop merely powers up the transponder inside the key which sends the EWS its unique key code. The EWS then compares this to the coded table to see if the key is authorised or barred - if authorised, it releases the relay on the starter and then sends the ISN signal to the DME for start up procedure - even if it sends this, the DME still compares the rolling coded table (some 200 of them) to the one burned into its once only memory - if the EWS's rolling code table isn't matched to the DME , the car doesn't start (this is the immobliser portion within the DME) - (to stop people swapping out precoded EWS modules in cars that are paired to stolen keys.)

This is why when you order a new EWS from BMW they code it to exactly the same as the one in your car - so the rolling code table matches up. Which is also why when you've used all 10 keys pre-stored in the EWS you have no choice but to buy a new DME and EWS and start the alignment procedure from scratch.

Your friend must be fairly smart to be able to crack into the rolling code table and wipe it from the start up procedure ... as far as I know that can only be done on EWS 1, 2 but not 3.

Couldn't have put it better myself Tom.

Hi,

NZ_M3 -Yes its been done by them and works well.

EWS completely by-passed.

They are currently working on a MSS60/65 whereby you
do not even require a key, or 'Card' whatever
you want to call it.

All the EWS etc is again all by-passed.

Even on the May 2008 ? onwards versions where
by the Diagnostic port is supposedly 'inactive'
for ECU access.

Forgot to mention they have just done the ECU
for Guy who fitted the V10 into an E30 M3
and have made several modifications
etc.

Clever and some.
