If anyone is transplanting a Euro s50b32, it's now possible to run the motor without the EWS module, receiver, and key/ring. I've managed to get a car running without those items. :devillook

Wow...

Thats all I have to say...and... way past time.

I recall well the day that Pierre Collet bragged to me that he had an EWS bypass from PTG in the form of a black box.

When it was opened, there was an EWS II module, key and key-ring inside.

Hi Alex,

I had this done for some time, but finally tried it out on a car here.

Is this different than when you said you could do this 2 years ago?

Was it that long ago? I don't remember saying that 2 years back. Maybe I said that I would work on it. Until about a month ago, my OBD-II serial programmer wouldn't even read the MSS50. There was an update recently that allowed access to it. What I had done a year back was remove the FLASH from the DME and read it, then dis-assemble the code to look for the EWS-II code, and disable it. I didn't actually test this till now as I wanted a serial programming solution for this. It's finally available. Next I'll make software for aftermarket cams.

Two years ago I figured out how to disable EWS-II in the Bosch DME 0 261 200 413 as used with the m50tu , maybe that's what you are thinking of?

you are the man!!! can you do the same for an s54 in and OBD1 car?

I have not tried to do it, but I should be able to. It's just a matter of spending lots of time doing it. There may be no payback on it, just as I doubt I'll ever recover the time spent on the MSS50 EWS delete by selling it.

WOW, that's pretty impressive, Mark. Check in with Alex Lipowich, I'm sure he can use this functionality for those who buy engines from him.

Hi James,

Alex was the first to reply to my post.

Yes it was about 2 years ago (unfortunately I had a computer crash about 18 months ago so any emails before that are gone) and yes it was relating to the MSS50.

I have nothing else constructive to say.

So is anyone going to spill the beans!?!? :D

YES!!!


I have a 03/94 build M3 awaiting (for quite some time) hook-up of its S50 B32 powerplant (specifically, retrofitting EWS II and all other wiring/plumbing) and this is EXACTLY what I wanted to hear!

Mark is my hero. :)

OR you could have just swapped me harnesses' and taken advantage of the fact my MZ3 one has EWS bypassed.

I assume that NickG did that? If not, where was it done?

I had the method figured out early this year, but was not able to re-flash the DME till recently. I wasn't planning to do this by de-soldering the FLASH and then re-installing it.

No, that harness came with the motor. It was originally in a LTW racecar but I could not track the original guy who did the swap though. (I am the third owner)

Nick aligned my EWS so I could use an M3 harness I bought. But until it was aligned, the car would not crank. It cranked with the MZ3 harness before that though when the EWS was not aligned.

Why go thru the effort of bypassing the EWS though? It doesn't take long to have it aligned, and the dealership probably wont charge more than $100... so how much could a bypass cost?

Do you have a perf chip for the Euro EWS2 S50B30 ?

OR you could have just swapped me harnesses' and taken advantage of the fact my MZ3 one has EWS bypassed.Now why would I want to trade my fully intact harness for a hack-job harness that doesn't fit in the E36 engine compartment properly?? Thanks, though. ;)

But seriously...what exactly is done to your MZ3 harness that bypasses EWS II? Does it have a Pierre Collett-like "black box"?

For any pre-EWS II chassis you don't have to retrofit the EWS II system (antenna ring, key, module, as well as plugs and harnesses.). Mark's bypass will save people like me hours of wiring. I'm glad I didn't do it earlier.

I've made one for the EWS-I ECU, and could transfer the maps into the later EWS-2 code. I won't have time to do that till mid to late October at the earliest.

I realised today that maybe that's what you were asking. I was first thinking that you were meaning that soemone else already cracked this, and that I didn't know.

I dis-assembled some of the code and figured out what to change.
I tried it out on a mechanic's street car which originally was one of the 45 Euro M3's that came to Canada. He has swapped in an s50b32 a few years back, and had the EWS bits tucked in beside the DME. He sure was surprised when the car started with the spare parts disconnected. :buttrock

It's not a hackjob. Side by side, it's actually nicer than the M3 harness I got and looks identical once installed.

Very cool, thanks. How would you rate the job for difficulty?

I'm not aware of any hardware fix that a harness could incorporate that allows EWS II on a euro S50B32 to be bypassed... course, there's a lot I'm not aware of.

I may have just gotten a hold of a bypass of sorts that allows DME's to be swapped around at leisure, as long as a EWS key and matching EWS box are in the circuit... but its a long shot, and even then, it would only mean that you could swap around DME's, and carry a spare without having to align them... you'd still need the key and EWS box (matched) to be in the car's harness and digital stream so to say.

(if this does work, I'll share)

Alex.

Have you tried to crack the MSS52 DME? Can you get rid of EWS and any other electronic nannies that put it into limp mode?

I just noticed that you were probably directing the question at me.

Now that I figured out how to do it, it's not hard to implement. But figuring it out was very hard, at least an 8.5 out of 10. :eyecrazy There's probably only one or two people in the USA that could figure out how do it, if even that many.

That's probably why nobody has said they can remove EWS from the MSS50 before.

I've got the MSS52 and MSS54 figured out to the point that I can get an extra 25 hp from the s62 in an E39 M5, and about 13 hp from an S54.

I worked on the ECU that was used in what I figure is the first e36 328 that got an s54 transplant, that was in 2005. It definitely isn't in limp mode, it has an 8900 rpm rev limit and it's taken there often.

i take it this was using the ECU that originally came on the s54 motor?

That's correct. I posted about it on BF soon after it was finished.
