Is it Magneti Marelli or Rochester ECU ?

I found by quick Googling  that 145/146 1.3 uses the same ECU as last AR33 with 1.4

Citāts:

Alfa Romeo    145 - 1.3 / 1.4    MARELLI - IAW - 8F.6B \ 46456318

I got at least 2 ECUs from AR33-907 1.4i

The info from the ECU box i have:

Magneti Marelli IAW 8F.6B
001  - EM1LJV23 - 057-93
Alfa 33 1360 MPI CM ECO
61600.088.03E 12V

And I remember - you`ve got 1.7 16V 2 years ago?

Hello Real Alfisti!!!
I am from Estonia and i am olso Alfisti. I have got an Alfa romeo 33 Permamet 4 but my engine has broken. So i am looking for the working motor BOXER 1.7 16V. Thanks for the he ...

Does it mean that this 16V finally died and You gonna make a downgrade with 1.3 ?

Hi Alsi ,

33 is in good condition, driving somewhere in Estonia, but unfortunately  i sold it .

So it is another car and another problem. But unfortunately 33 and 145/146 has a different ECUs. 145/146 have some kind of updated engine using new camshafts and gearbox. So they are not the same. But thanks anyway!

 
My numbers from ECU:
Magneti Marelli IAW 8F.68
IAW8F.68/0909-A6 B
46456318
61600.324.03Z 12V

What happens with old one?

What happens with old one?

When i got a second engine, i installed it in to a car. On new engine i changed timing belts and pulleys, spark plugs and other necessary stuff, also car had a new clutch plate and bearing. so when the car was almost finally ready i made some test drives to ensure that every thing is working properly. And on the last one when i pushed a littel bit harder something broke in clutch mechanism. I was so mad!    because i knew that i have to remove second time engine with gearbox! so decision was simple: to sell a car! And actually i sold it in a one day. After selling a car, i realized that it was a very stupid decision it was mistake! but it was to late.    So i now that problem was in clutch disk. and it was simple problem.....

So my small advice to every one when you repairing you car do not get mad, and do not try to sell a car!

some video of my first engine start, ..... memories.....
NB!! On a video car has not got exhaust system installed yet so it is very loud!!!

 



 



Memories...

I mean - what happens with old ECU from 1.3 145?
Old ECU are almost bulletproof and it is really hard to destroy its electronics...

Car has not got idling speed. You have to always push the throttle .
At first diagnose showed that the Mass Air Presure numbers are totally wrong, so i had another MAP sensor to try (working one). But problems has not gone. After that i checked ECU and it showed that ECU is generating signal it self, instead of receiving it.

Do not relay on number incorrectness - the MAP could be good anyway.
Do you hear some sounds from Idle Control Servo Valve (stepper motor onto throttle axis) during ignition ON/OFF?

All of that is OK. The main problem is when you push the throttle ECU receives/generates wrong MAP sensor signal. And as a result engine do not work properly and there are not idelling speed of engine
