is ews a separate unit?

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

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 :hahaha:

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 :thumbs:and we all live happily ever after:hahaha: ) ....

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.

Hi,

Even Bimmerworld in the States
will sell you a Std MSS54 ECU with
the EWS/Imob deleted.

Yep this has been done on my car.....this is how I know. Not sure on the intricate details but the guy I use can do all of this and more!!

Apologies about the duff info on the separate EWS module, you are correct, but it is the software in the ecu that is changed I was informed, not the actual EWS module which also contains info on mileage etc etc.

Hi,

The Guys in Germany did the
ECU etc for the Guy who has
put the M5 V10 engine into
his E30 M3 in the UK.

He started with a std SMG III loom
std MSS60 ECU which has now
been converted etc to run in the
E30 M3 but with a Manual S65 V8
G/Box and retaining the std ECU !!!

All the EWS / Imob stuff is long gone.

They have even provided the facility
whereby he can plug his laptop in
to the MSS60 ECU etc.

My MSS65 ECU should be ready early
next year.

As Cantfind1 has posted MSS54 ECU's running
which have had the EWS / Imob by passed
are done by the ECU being told, do not ask me
how, that the key/EWS etc is all good and
present, when its not.

Its some sort of Software script that they
upload.

If I remeber correctly One of the Guys
they work with did all the electrics for
a client that fitted a V10 with SMG III into
a E46 M3 which all works and functions
as seamless as if BMW had done it.

Its beauitfully executed as well.

Go figure out all the issues with that lot.

Some really clever Guys out there.

The Gorilla.

Can you provide some info on who these guys are? I have an idea for my car and I want to see if they can do it
