    Hi All

    I have recently put a 1996 s50b32 3.2 evo into my September 1994 M3, 3.0

    The evo engine was running fine when removed and diagnostic read with no faults, the engine came complete with harness, DME, EWS modual, transponder, key chip and antenner ring.

    Engine all in connected up and earths from engine to chassis checked,

    Next was to wire up the Ews II

    EWS II wired in, EWS modual to permanent live (checked), and earthed
    EWS transponder and EWS modual connected via blue wire.
    EWS transponder connected to ignition live and earthed.
    EWS modual connected to DME via thin green wire, (PIN 7 in 20 pin plug)
    Key chip secured inplace.
    Can here the EWS modual and starter relays clicking when key hits P2

    Turn key in ignition, lights come on, fuel pump primes, engine cranks and then fires up, 2 secs later engine dies. Injectors and spark looses power? Dispair

    To add to this current confusion!!

    The car starts and the dies even when the EWS II modual does not have any power to it, which I thought was very strange?

    How can it start if EWS II is not wired up

    The green wire going out of the EWS modual was also live after key had been turned, is this correct? Did modual get its power from here?

    crank / cam sensors all checked and working fine, if crank disconnected engine wont fire, new cam senors purchased and swapped around, no difference.

    My latest thought

    Could the EWS I originaly installed on s50b30 be interfering? I have read the PDF on the EWS series, and on the EWS I the starter immobilisation relay required signal from

    the door lock mechanisum & GM
    the board computer, (the OBC)
    The DME - through pin 7 on the round 25pin plug. (Thought on this, would the fact that this original DME is no longer there be upsetting the EWS I system.

    An added feature of EWS I drive away protection system was a reading from ther Engine Speed senor, on the 6 cylinder models if EWS did not have all correct signal it would cut power to injectors and ignition spark, was the car got over 1200 rpm.

    When the engine starts the revs just about get above this level before it dies...

    Can EWS I be removed / disconnected?



    I also had diagnostics run

    00156, DME cant alter engine torque
    00066, Alarm - could this be issue, with fuel cut off
    00041, MAF
    00073, Throttle valve potentiometer ( throttle position sensor)

    Also when diagnostics run, we inserted a bulb into the injecter rail power socket for number 1, it lit up intialliy indicating power, then went out after a few secs,

    any help / thjoughts much appreciated.

    The evo does that with the EWS, it will fire for a short while then cut off.
    As it cranks, the EWS box is happy with the key, but the ECU isn't getting the right signal to release it.

    Thanks for the info,

    So essentially this means I don't have the Green EWS wired to the DME correctly.

    I have taken the wire coming out of the EWS Modual, and attached it directly to the thin green wire coming from pin 7 (round plug). I have attached with a normal spade connecter.

    One thing I did notice was there was another thin green wire which came from the DME and into the harness, this ran the length of the main black box which houses the wirirng harness to a dead end. I did try to connect the EWS modual to this;

    Which stopped the fuel pump priming, and the engine cranking, so I put it back, which returned to fuel pump prime and engine crank plus fire and die.

    Is there a certain way the EWS modual green wire needs connecting to the DME?

    Or could it be the pin connection (no 66) on the DME which is bent or damaged, hence why error 0066 showed on the code reader.

    I will check this out and report back.

    It is slightly more than coincidence that the pin number often tends to be the fault code number from that component.
    I've noticed that on quite a few ECUs now, but it is not entirely perfect.

    Things to do -

    check the wiring to make sure that the EWS output wire from the EWS box is going to the correct ECU pin, and also double check that you have the correct ECU Vs. EWS/Key, as it is acting the same as if the ECU was swapped.

    Will Check, EWS and Modual are the same, I bought the engine of Chris of CR m tech, who I think is a top bloke, and helped me with originally understanding how to wire in the EWS. I'm confident it should not have been mixed up but will double check.

    Would their be an extrier code on EWS modual, DME which should match to indicate they are from same car?

    Thanks

    Nothing obvious on the EWS or chip key, it's all electronic and inside the boxes in codes.

    I had an issue like that too. The EWS isn't happy as the good man above says. I ended up giving the two brown wires their own earth.

    Also are you using the 3.0 engine connector car side with the 3.2 engine loom? If so the wire's not quite match up properly and you'll find a few pins missing off the 3.0 that are on the 3.2.

    If you PM me your email i'll send you a copy of the wiring diagram I made to get mine running.

    YER YER all sorted

    Massive thanks to Enda for his help today.

    So what was the issue, well me being a clever dick had set the ews transponder up under the steering column, I had then tapped the key chip on to one of the relays, about 4-5 inches away from the antena ring...

    And there people lies the issue, the key chip has to be right next to the antenna ring, even to the point where it must be on the correct side of the ring, other wise she is not happy and will start run for 1.2 secs roughly then die.

    As my key is none chip i'm going to try and take it apart, remove the light and place the chip in its place.

    Now to fit

    FK tunning fully ajustable suspension
    Camber / caster topmounts
    Simota induction
    Arb
    Rear adjustable camber arms

    ring trip in August can't wait
