Smile 95 318ti to 98' 328i single vanos swap

Hello,

I'm doing M42 to M52B28 swap, everything is swaped,
I've switched EWS and engine wiring harness plus DME
together with M52. First there was no sign of life from starter.
Then I've switched chip from donor car key to mine and starter
is working (so I assume EWS - DME - Key is algned?)!
My problem is that there is no spark and no fuel pump reaction.

What I'm still mising?

Also I don't have one round connector close to fuse box.So ths from
the engine wiring harnes is unconeccted.

Any help, plase !

No reaction, so I try this:

Could OBD-II engine to OBD-I chasis swap be done?
I've read posts all over, and found that there is only
OBD-I engine to OBD-II chasis instruction. My 318ti is
from 10 october 1995 M42, how could i check which OBD
it is (did OBD I had EWS II like mine has?).

Help please, I cannot sleep

I believe the OBDI to OBDII is a lot more difficult than keeping it the same or going back, if it's a 95 model year it's OBDI

Great, thank you !!

Now I need to be sure that my M52B28 is OBD II or maybe I,
since I bought it without papers i don't know from which year it is
seller claims that it's from 1998 but I doubt it. on wiring there is
"lieferdatum 06.09.95 20:35". I spoke with friend, and he told me
that easiest way to recognize OBD is connector - round one in engine
bay for OBD I and similar to rectangle for OBD II located in cabine - is
that true? If it's OBD I to OBD I then i don't have to do extra work with wires?

Regards !

Most people convert OBDII engines into OBDI rather than converting the chassis into OBDII.

Default 328i to 318ti OBD I swap

Still fighting with wiring.
I found out that I have OBD I engine.
Is there anyone who made M52B28 OBD I ('95 or '96)
to OBD I 318ti '95 ?
Engine cranks but no spark and no fuel, and I'm running out
of options.
I've made horrible mistake connectingo G117 ground to battery
positive. I've reversed it but could I fried my ECU or some fuse?

maybe there're some differences in x20, or I need to add UNL (I cannot
find one in my car or the engine harness) ? ECM an Fuel pumo relays are not
kicking in, there is only low voltage on them (2 or 6V).

Engine spoke to me !!!
Problem was simple, no positive for ECU.

If someone needs x20 pinout for 328i 96' to 98' and 318ti 95'
(i couldn't find it on internet and it took me 4 hours to make them from ETM)then I'll post it later.

Thanks for all replies !

Question Working MPG on OBC [318 to 328i]

I've serched forum but I cannot find a clear answer, is it possible to make OBC MPG working correct? I have still 4cyl instr. cluster (new 6cyl. is on it's way) and my OBC is showing 3,8L/100km (around 60 MPG ). Anyone have accurate readings with M52B28 on board?

So? If it's question, I don't know, after long reserch I assume my '96 M52B28 is OBD I and '95 318Ti also (or both are OBD II). 318Ti had very accurate MPG readings, after swap it's much to low. Is there any way to correct it?

a 96 is OBDII and a 95 is OBDI, just noticed you're from Poland though, so I might be wrong
