if you used the 325 loom and ecu....surely the chip key part from the 318 wont be connected?

cossiecrew

ive used the engine managment loom basically same as a cossie when you buy the managment loom you dont get a complete car loom

Graceland

The engine management loom should be seperate like on a cossie, a big round plug near the fusebox to get it to the car loom

Just double check that the loom plug is the same pinout on the 325 loom and 318 loom as I feel there are slight differences.

cossiecrew

i know its seperate ive fitted remember lol. the pins look the same to me the fault on my mates snap on tool came up with a code called dwa? which is the anti theft code

Jim Galbally

these guys will know:

few ways round you problem

cossiecrew

already on there jim no help as of yet

AAman

you snap on tool will tell you that because the car is showing that fault, the engine control isn't getting the imomobiliser code, because the ecu isn't there.. if you get me... you really need to find out what the immobiliser cuts out, fuel relay, starter relay etc.. and get round that... if you can power up your fuel pump, and starter, and have seperate power to your management you should be able to get it to run...

AAman

btw, i'm in the midlands, and have a garage if you are stuck....

Jim Galbally

its not an imobiliser, its a coded ECU, he can't bypass it with some wiring

your best bet is to get the modules off the old car TBH

cossiecrew

the old car didnt have it. and it has fuel and spark so must screw the timing or something like that ive thought about ripping the dash out and trying to remove anything ews and just using the barral and key off the old 1 failing that im going to push it in the canal because im getting to that point with the fucking car lol

the ecu your using isnt the coded one though is it?

JTECH James

if the barrel has a chip reader it surely plugs into the ecu loom to imoblilise it....?

in which case it wont be plugged in, as your ecu loom doesnt use the code key jobbie....


the car loom wont stop it running

AAman

i'm not trying to bypass a coded ecu with some wires... I'm sure the ecu isn't coded on early beemers.. what i was getting at is that the cars body control unit may cut the feed to the fuel and or ignition, and without the signal from the engine ecu the immobiliser willl not come off... however, if the old engine ecu and wiring is standalone, as the cossie type is, then all it should need is a live and an earth to the ecu... providing the engine has fuel and it cranks over, it should start.... the immobiliser is never going to mess with timing...

Jim Galbally

later E36s do use coded ECUs yes.

but i see what he's doing, uncoded ina coded car, in which case just do what you said and switch the stuff out!

JTECH James

but if the loom and ecu are standalone, how can it be imobilised by the code....the code stuff shouldnt plug into the loom....

AAman

some stuff 'talks' between body control and engine control ecus depending on what systems are used, like if the body control units works the fuel pump, it will take a signal from the engine control and other things like crash control ecus etc.. beleive me, when I worked for the AA I came across some of the most bizarre setups that have you standing at the side of the road scratching your head!!!! you'd be amazed what can be acheived with a fused length of wire!

JTECH James

that to me is far from standalone....and therefore has no resemblance to a cossie loom

AAman

all i'm saying is that the engine part of it, as in the bit that controls injection and sparks is on a seperate loom....thats what I meant by similar to the cossie loom... however the car in it's original state may require all of the matching bits to function properly...

e36 bmw car looms are the same some have ews some dont the ews runs into car loom which has as jim said theres a round connecter with loads of pins where you plug your engine management loom hence my saying same thing as a cossie and probably alot of other cars one of thos pins must have the ews running into it had i of changed the complete car loom(a big fooking job) i wouldnt have this problem but as im past that now i dont want to go and do that so there must be a way round it

JTECH James

a cossie loom plugs into the engine sensors, plugs into the ecu, give it power and earth it runs, standalone....

your bmw loom is nothing like that, you may have canbus, or fibreoptics floating around in there as it comprises of more than one ecu i expect, the imobiliser being in one of them,

far from simple to overcome, goodluck

cossiecrew

so you think trying to remove the ews is a no go then?

lardypants

i really do feel the easiest way out of this is to get the remainder of the loom out of the earlier 325

the ews system is a reet fookin basitid, been there done that on a convertible i had, ews fooked up.

cossiecrew

what route did you take ? did you remove it from the loom?

lardypants

no in the end i sent it to bmw new ews 2 module new transponder bit and coding


seriously the ews is a fooking coont to get pass

it all depends how it works, it is possible its just a feed cut, or on the otherhand you may need the whole lot changed over...

try getting the two cars wiring diagrams, and compare.

i expect your older ecu is being fed coded info it doesnt understand, you need to find where this is going into the ecu, and what it needs in its place.it may be several feeds..it may even be impossible...


without diagrams im guessing tbh

lardypants

i asked everyone possible for a bypass no fooker knew how to do it, most said it wasnt possible, but then spose theres allways a way some how

cossiecrew

well cheers for everyones time ive fixed it

cossiecrew

took me under a minute to get past

lardypants

you better pm me the details as allways handy to know how to do them

lee

cossiecrew

you have pm

good stuff mate!

cossiecrew

it came so close to me getting the cutting gear out and ending its life mate i tell thee lol
