Any EWS experts..... EWS 3

[jmc330i]

Hi guys.

I have an engine from a 98/99 Compact 318ti. Up until 09/98 the compact had EWS2, but after they had EWS3, something called EWS 3.D to be precise, which seems to not be the full EWS3.

My understanding was that EWS3 does away with the separate transmit/recieve module (as on EWS2) and has an all-in-one EWS module that the antenna ring plugs into.

The version I have (EWS3.D) has the EWS module and going by the ETK, also has the transmit module that the antenna plugs into - Im waiting for the transmit module and associated wiring to arrive.

Does anybody have any experience with this EWS3.D?

Basically Im hoping wiring the EWS3.D will be the same process as the EWS2 I wired in for my S50 conversion??

Can anyone help??

Cheers

I had this problem with my compact, i had to convert an EWS3 car to run an EWS2 engine (M52)

From memory, i literally had to cut the wires and match them to the correct pin numbers on the EWS2 module.

pins and colours on both modules, from my notes when i did the swap.


EWS 3 pin configuration (pin no. - colour - function)
1 - BLK - Ground
2 - RED/YEL - Fuse 31
3 - Auto only
4 - WHT/VIO - Diagnostic
5 - BLK - DME control unit
6 -
7 - BLK/YEL - Starter
8 - GRN/BLK - Ignition switch
9 - VIO/WHT - Fuse 45
10 - YEL/BLU - Toroidal coil
11 - YEL/BRN - Toroidal coil
12 -
13 - BLK/GRN - ZKE control unit
14 - GRN - DME control unit (immob. device)
15 - BLU/RED/YEL - Control unit, remote control


EWS 2 pin configuration (pin no. - colour - function)
1 - BLK/YEL - Starter
2 - WHT/VIO - Diagnostic
3 - GRN/BLK - Ignition
4 - GRN - DME control unit (immob. device)
5 - RED/GRN - Fuse 31
6 -
7 - BRN - Ground
8 - BLK/GRN - ZKE
9 - Auto only
10 -
11 -
12 - BLK - Instrument cluster (engine speed input)
13 - BLU - Transmitter module
14 - BLU/RED/YEL - control unit, remote control
15 - BLK/GRN - obc

Pins 9, 10, 11 in your EWS 3 module do away with the transmitter module required to run the EWS 2 - so, you've got to put one in, in order to convert back to EWS 2. Go to a scrappy and grab an EWS 2 transmit/recieve module, if you don't already have one.

The transmit/recieve module takes the VIO/WHT Fuse 45 and an earth for power. It recieves the signal from the toroidal coil around the ignition barrel - so the YEL/BLU and YEL/BRN. Then it gives a single output for the EWS 2 module - the BLU in pin no. 13.

Might be more info in my build thread.

HTH.

Nice one, that does help having the pin numbers etc

Pins 9, 10, 11 in your EWS 3 module do away with the transmitter module

Im not going to run EWS 2, I will be using the EWS 3.D that came with the engine - this version has the same antenna ring as EWS 2, as well as the separate transmitter module.

Im hoping I can use the info you gave above to use the EWS 3.D that came with the engine.
