another "would this DME work question?"

[yanal]

so after i searched and searched about everyone says i must get the red label 413 DME for the s50 swap, but going thru the wiring schematic i believe that this DME should work just fine, anyone tried this one ? final verdict aye or nay ?

[Danny]

Yup. I have a 506 running in my car.

[yanal]

sweet ! thanks,,, now the diagram says i need an active high input to the DME from the clutch when its depressed, did you have to wire it or i'm just going overboard with this ?

[Adrian_Visser]

You're going overboard. Some 506 dme's have ews so be mindful of that.

Mine came out of 6/1994 US M3, after little research it turns out it does have EWS but its EWS I, not EWS II, EWS I its a simple anti theft security that checks if the doors were looked from the outside, or if the gear is in neutral in automatic cars and,, etc if i understand it right, and it does have a separate EWS module according to realoem, BUT no rings on the ignition or any sort of exchange between the key and the DME.

Thats why i was wondering if i have to tell the DME, hey listen no one broke into the car

[Adrian_Visser]

EWS I still requires a chip to delete it.

[yanal]

ouch ! so i'm out of luck ! thanks for the feedback, i'll try to bypass it without a chip and i'll report back.


and if anyone is interested heres a good read http://www.unofficialbmw.com/images/BMW_EWS.pdf

It ain't Gunna happen buddy gotta get a chip. Or a red label 413.

So I wired everything up today and the car started right away with the EWS 1 silver label 506.

Nice! So did you end up getting an ews delete chip? I have the same dme but never tried starting the e30 without the delete chip. Just wondering if you got it started without one

[yanal]

No ews delete chip, it was made in 06/1994. I'm most certain if yours was made prior to 01/1995 it would work just fine without a delete chip

Oh ok that makes sense. mine was an 08/95 so i definitely needed the chip
