Calling all S50 convertors !!! Spagetti !

[bigpimpin]

Recieved my Evo engine today but not sure If I have got everything. Can anyone tell whats missing? I can't see a "big box" for the main ECU. I should have ECU, Vanos ECU and EWS module/antenna. Please help!!!

Firstly, if it's an Evo 3.2L engine, you won't have a separate ECU and Vanos controller. It was only the 3.0L M3 that had these. On the Evo they combined it all in the main ECU. Have you checked the ECU is not with the engine, as the main ECU connector is part of the engine wiring harness, not the in-car harness you have there.

Not sure what the box is in your first picture, but it's not what you need. The unit in the second picture looks exactly the same as my Tracker unit. It's certainly not a BMW part. I don't recognise anything in the other pictures either. Looking at the steering column, it appears that the EWS antenna has been removed from the ignition as well.

Here's a photo of the EWS antenna and transmit/receive module.



I don't have a photo of the EWS module, but it looks like this:



The ECU is a silver alloy box with a large multi pin connector on one edge. It's made by Siemens, not Bosch.

Cheers,

Ian.

Ian, Do you have a photo of the ECU so I can send it to the guy so he knows what it looks like?


I'll have another look tonight for the EWS stuff. I definately dont have the ECU. I looked at the engine harness and saw the long plug that attaches to the ECU but cant find the box. I'm chasing up the seller now. If its gone AWOL Can EWS/ECU's from different vehicles be made to work together?

Cheers.

As long as the ECU, EWS module and ignition key are from the same car, it will work fine. It is possible to align an EWS module to a different ECU, but the EWS module and keys are coded for life and cannot be changed (although you can disable keys, you cannot add them). To code the ECU and EWS together, you would probably need to find someone with an E36 Evo who is happy for you to code the units on his/her car.

Ian.

Hi,

As Ian has stated, the parts you listed are not shown.

On the EWS, ECU and Ignition Key, you will be able to source a '' Thief Kit'' as its referred to, expect to pay around 275-325.

A Z3M Coupe or Evo 3.2 can be donors.

It is essential that you get a matching Key and ECU, otherwise, I do not beleive you will ever be able to make it work.
BMW will not supply Keys for ECU's unless you have the Supplying Dealer paper work, and then they sometimes refuse.

Wiring, unless you know what your doing, my advice, is find someone who does.

This may sound harsh, and not want you want to hear, but in not knowing if the EWS, ECU was even in the 'jumble of wires' then I would think long and hard if I was you, on how you tackle this project.

Getting the engine / box into the car [plumbing it in and bolting it all, etc] is the easy bit, even including the Exhaust Manifold and Steering issues.
Wiring it up, intersecting the Engine loom into the car loom, converting the pulse for the Rev counter and making it all work and function correctly is the really clever bit.

No, not scare mongering, just telling it as it is.

People with the depth in knowledge and the first hand experince of this conversion are not around every street corner, Ian332i, is quite unique in being a, Planner / Converter / Owner / Reference, in regard of this conversion.

And just so you know, yes I have done it, and the wiring was the most expensive, frustrating, time consuming part of the conversion.

Regards,

The Gorilla.

I don't have any good pictures of the ECU. You can see it sitting on the engine in this picture which may help.

Ian.

My engine came without keys (although it did have the matching ECU and EWS module). My dealer was able to supply me some keys after I proved that I had bought the engine. I showed them the receipt for the engine, as well as my V5, driving license and address etc. I also had the VIN number from the car that supplied the engine. I also had my car serviced at that particular dealer, so they knew who I was. I guess if some bloke wandered in off the streets they may get a bit funny about it.

Thanks Ian, I've sent the pic so fingers crossed!
Gorilla, I know what your saying, It is a BIG project for me but I'm gonna give it a go. And everyone on here is very helpful especially Ian and James.

I certainly don't want to be advertising an "unfinished Project" in 6 months time!!!

[buster]

this is the ecu from my 3.2 evo engine.
EWS box
Loop antenna
Transmit recieve module
Key.



These are what you need

[bigpimpin]

Cheers buster, nice clear pic.
I've got the Key, EWS box and the Transmit recieve module so thats a start!

Need to chase the ECU now!

[bigpimpin]

Well, looks like the ECU has been crushed with the donor car

Spoke to my local dealer, got a quote for new parts but I aint paying Ԛ£600 for an ECU so looks like I have to find a "thief kit" mentioned above. What a ball ache

Hi,

I have sent you a PM which may or may not help.

[bigpimpin]

Thanks Gorilla, got a set from a Z3M coupe from the place you mentioned.

Engine and box went in this weekend and everything went like clockwork!

[buster]

looking good there.Its a while ago since i was at the stage you are at now,good luck with the rest of it.

[bigpimpin]

Cheers Buster, think I'll need it ! Probably not get much done over the next few weeks but will start in earnest mid January.
