All of this win and then you get DZ101s... :( Put some real tires on there! :p

Gearbox chatter is furaze. Is that how the kids spell it ha?

Still working on the wiring at the moment. We now have the starter motor working on the actual 'starter' key position and not ignition. It was to do with the starter circuit pin out differences on the loom adapter for face lift vs pre-face lift. I have a pre-face lift obviously :) a quickish re-route in the fuse box sorted the start problem out. However we are still not getting 12 volts down pin 15 or pin 16 down the diagnostic port. pins 14,15 and 16 should have 12volts running through them. We again are checking the dfferences in the pre-face lift loom. Confirmed this on Ray's M-Coupe.
Anyways so not startup glory today so instead I took a trip down to see how the new wheels are getting on.
They have finished the barrels and are just working on the inners., black bolts still to come but ill save that for when they are mounted on the wheels.
With out further ado, Arrow wheels work their magic
This is the bit they used to drill the PDC and the caps they press into the holes.

Welded and in the middle of being milled.

new wholes ready for caps to be pressed in

A new colour they have made up for me, Ill name it hybrid gunmetal :D Tested on one of their spare centers to show me what it will look like and give me approval for the go ahead. Note its tastefully darker than the standard silver (in the back ground)

Barrel win. Polished lips :)




enjoy..

Update.
More wiring (12 hours of it) and connecting up of misc stuff like booster air lines etc.
What a day yesterday was.
EWS is a steap learning curve, We started out but checking the loom and electrical diagrams for the e30 and e36. by about lunch time we had found that the pin 15 voltage problem actually wasn't a problem at all. Its just that the e30 doesnt have an EGS/IKE/etc to put 12 volts down the line back to the diagnostic port. So we jumpered it across from another ECU pinout.
The pin is only used to tell the diagnostic equipment that the ECU and modules is present and accounted for.
With that problem out of the way and confirmed, we could suddenly take reading from the ECU. YAY!
however we were having issues addressing the EWS. So back to the diagrams.
I noticed while I was looking that the EWS unit we had only had 'EWS' written on it. I asked ray to check his 2000 M-Coupe and it had EWS III written on it. AHA! we had an EWS I unit, crap.
SO out we went to search for an EWS II + key. again turned out to be a bit of a mission. We had worked out they (EWS II) were only produced between 95 and 97 so finding something was going to be hard. We searched all 5 series and 3 series cars and finally found one in a 318ti.
Awesome, so here we go again. (the sun was going down at this point)
Plugged in the EWS II and got a different bunch of error messages saying the EWS unit couldn't find the key. YAY! at least the GT1 computer had found the EWS module.
Brendon had read somewhere that you need to make sure the key is in the right position, so he adjusted it, we cleared the fault codes and tried again.
Success!
Cool so were not had a working system ready to code.
Brendon and I complete n00bs with progmanSSS ray made a 8:30pm on a saturday phone call to the dealer and he explained the start proceedure.
Reading all instructions and linking up extra batteries for constant current while programming, we set off to code.
message: you need atleast 13 volts to performing coding
Crap! .. time to bring in a running vehicle and jumper cables.
right now we had 13 volts.
We could now code. We tried and tried and tried but go stuck at the need part number for replacement module screen. so at 10:30pm we decided to call in a night.
We are going to look at using my carsoft software as its not so anal about part numbers etc etc and has a simple function to just align DME -> EWS. So will give that a go.
Once the EWS is aligned the car sould just start.

Update:

TITS!!!

P.S it was up to operating temperature before I did this :)

Woo Hoo.
Kick 'er in the guts Trev.

[HybridNz]

Haha yeah, just need to tidy up the loom / covers. Re-bracket the new expansion tanks / bottles and sort out the sway bar links and spacers we are going to need and fan and wiring then its already for the road.

[JamesE30]

AWESOME!!! Nice work, I <3 this thread.

[Ray Smoodiver]

Just picturing you rollin, flossin a tec-1 on rims that isn't stolen

[Jean]

Awesome build man! I was just following it on e30zone too :)

[Iain]

So much win... congrats!

[Jean]

OP - can you explain this further, you couldn't make sure of the existing line to the external pump? did you replace the original line from the internal pump to the external pump?

" had to run two fuel lines the one from the tank to the fuel pump was larger diameter and the one from the pump to the main fuel line was smaller. The oem pre-face lift configuration about explains why."

cheers fellas! Brendon and I have been waiting around 2 weeks for this point. Ill post all the wiring photos when I get off easter off easter holiday. We ended up using ProgmanSSS to program it in the DME section. Realoem part numbers where the key. Enter the Base DME partner number first then pick the closest 'programmed' dme part number that suits for the replacement DME .. in this case M3 s50 programmed with cats.
supply constant 13+ volts during programming as not to brick the DME.
Make sure the chip is able to be read by the reader coil. Chip position is very sensitive. The car will actually fire with no chip however it will die pretty much straight away as the DME doesnt approve.
It is a good idea at this point once the car is started to kill it and re-diagnose the modules to make sure everything is squeaky clean.
and away it goes :)

Wiring pics as promised ..
Finished up the covers weds night. Things left to do are sort out permanant earths for the engine etc, Sway bar mounts modified, clutch and expansion tanks mounted on OE brackets to body and sorting out the radiator fan and wiring.
So it starts..
Removed the e36 cover to expose the wiring. Lots of un-nessecary coppper in these things :( bit of a birds nest too for straightning out.


Separation of the loom DME plug so with fit through the firewall. I hear all sorts of stories/posts of people enlarging the firewall holes with a hole saw .. I dont get it? just pull the plug apart and feed it through and re-construct back on the other side.
Great thing with Siemens and Boshe plugs, they are meant to be pulled apart for pin additions. Taught ourselves that when doing my e46 satnav retrofit.



Through the other side.
EWS and DME wiring



Reader coil wiring and chip placement.

Fuse box wiring back to ignition

A nice little spread sheet of the e30 pre-fl vs e36 engine loom with colours.

Packing the loom together behind the new plastic shrowding for a nice OEM look and finish

[JamesE30]

Very nice!
The engine bay is really coming together@, I love those wiring harness' they finish the look of the whole thing. I even put one on my m20 hehe
Keep up the good work :up:
