Alright i did search this and i came up with a few hits one seemed to be cutting #66 on the dme. But i want to make sure and check with all of you.
Basically im almost done with my s50b30 swap the motor is in everything is connected PROPERLY, and i have done alot of troubleshooting. The Motor cranks but there is no fuel and i dont think there is spark either. I jumped the fuel pump from the relay and it went on, I even bought new relays just to be sure. so now it has come down to EWS or a bad DME? Now the Ti that the motor is going in is production date 5/95 so would it have ews-2? the Original dme ended in 282 so i believe it did would this be the definite cause of my problems? if so i would just have to get it aligned? correct?
Or could i just cut wire #66? leaving my car with no ews.
thanks in advance

I tried to jump the wire. I have a spare module I could open up and take a pic for you, any progress? | | | | | 05-22-2010, 11:16 PM | #4 | | Senior Member Join Date: Feb 2009 Location: new york Posts: 511 |
I cut #7 already it still cranks but no fuel and no spark I just need to know which connector behind the glove box is for the ews so I can jump #1 and#3 together because thats seems to be the way to delete ews 2 from the chassis itself | | | | | 05-23-2010, 12:43 AM | #5 | | Moderator Join Date: Mar 2007 Location: Maryland Posts: 3,220 |

Basically what i believe the problem is as i said earlier is that the Chassis is ews II and the Dme/motor is ews I so i need a way to either bumb down the chassis or delete it completly. | | | | | 05-23-2010, 12:54 AM | #8 | | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 |
Meh, use a red label dme with s50 software. EWSII wouldnt even be an issue as the DME wouldnt look for the DME to begin with. Ive done this on all my chassis' except the 95 which was cut the wire and done. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Well from what i read i also read your OBDII writeup is that the EWS II in the chassis of the car is preventing it from starting. and the silver label 506 is not supposed to have EWS so i should'nt need to switch DME's but from what i see your the Guru on this part.

Im pretty sure that my write up says red label is EWS0, prime dme to use. Silver label in 95s are EWSI which can be cut on an EWSI chassis. On an EWSII chassis, a red label should be used and wire cut or you have the option to just have the system aligned by the dealership. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

That is correct the silver label 413 has ews II but from previous thread i read that the silver 506 is also EWS0 so i just cut pin #7 lime green and still nothing. from what i read on rev limited was that there is a way to over rider or bypass ews in the car through the ews module behind the glovebox but im not sure anymore i thought this was simple but this is becoming more confusing as it goes on. So from what your saying i need a red label 413 with an s50 chip? but also my Prod date on the m3 was 7/94 so is that still ews I? | | | | | 05-23-2010, 01:17 AM | #12 | | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 |

So either a chip or a red label 413? as it seems the 506 has ews 1 i need to instal an s50 chip into the 413 though correct? | | | | | 05-23-2010, 01:28 AM | #14 | | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 |
