I suspect both from your experience and the above circuits that the 123 is not a replacement for the 111 and someone made a mistake when that was published.
I only ever got good used Bosch modules to work properly but I never tried the BERU. I now longer own a V6 Alfa so I will not be doing any more experiments.

I appreciate your help and will see if the four used modules I ordered from three different sources fix my problem. I have one used Bosch 0 227 100 111 that does not work in either Milano. I call Larry Dickman at Alfa Parts Exchange and he calls me the Milano guy and hope that he stays in business for a long time.

OK, it seems we have been looking at the wrong place! Looking for inductive trigger replacement, while actually the need was for a hall trigger replacement. I have a distributor for 3L 75, which I opened up and it has the drum with 6 slots arrangement for hall trigger. So this distributor which then possibly have also been used on late GTV6 s, has the Bosch number of 0 237 322 001. So the correct ignition module for this is 0227 921 036. The one to look for, according to Bosch catalog. Hopefully better luck with this one!

I received two used Bosch 0 227 100 111 ignition modules from Germany and both modules work. I also received another used Bosch 0 227 100 111 module that does not work. I have not received a coil/module from Israel and will see if it works. I currently have one spare module and coil and two broken modules with a new Bosch 0 227 100 123. I will probably return the new module to the BMW shop because it can be used in BMW cars. I purchased a used Bosch distributor and should install it and see if it works. This is the problem of owning two old Milanos and I buy parts wherever I can find them. I have many new and used Milano parts in my garage including a used 164L engine. I have given serious thought about buying a new Giulia QV and retire the two Milanos. I have been driving them since 1988 and they are good cars as far as I am concerned. I would caution anyone who thinks that they can buy a used Milano because of the parts situation. I also put heat conducting paste on the bottom of the module.

The ignition module 0 227 100 111 will work as a direct replacement for the alloy cased 0227 100 017.
I have swapped mine over, My car has the two-wire VR inductive pick-up distributor. I used the module from my written off ALFA75 which has the three wire hall effect pick-up. It works perfectly with no over-heated coils, poor performance or misfires as long as you have the whole ignition system correctly wired.
My alloy box 0 227 100 017 amp had these colored wires they connect to the 0 227 100 111 as follows.

black/white.......................................connect to #1
black...............................................................#2
green/black .....................................................#4

The 2 wires From the distributor are as follows
green and shield

green...............................................................#5
shield...............................................................#3
#6 and 7 are not used
You can use a BOSCH 0 227 100 111 a Tridon TIM 017, Fuelmiser CM413 or a BERU ZM 001 as a direct replacement for the 0 227 100 017 alloy box.
You will need a Bosch EV1 7 pin male connector. No other parts need to be replaced or modified.

Could it be that the sine wave pulse generated by the earlier inductive pick-up is still read by the ignition module because it only receives a signal once every engine revolution?
So be it a sine wave pulse from the two-wire inductive pick-up distributor or a square wave pulse from the three wire hall effect system the ignition module reads the pulse because they pulse at the same rate.

Cheers Sportiva

Have you seen a sine wave from the VR sensor? I have not had the exact one that is used on the early GTV6 on the bench but I have had other VR sensors and they made short duration voltage spikes.
It is a mystery to me how you have got yours to work.

It doesn't just work for me it is a very common swap. there are more inductive pick-up GTV6's around the world than the hall effect models. From 1983 American GTV6'S used a hall effect distributor the rest of the world kept the inductive pick-up until 1986.

Maybe that is why it only works outside of the US :wink2:

I just received a Bosch coil and ignition module Bosch 0 227 100 111 from Israel. I installed it in the car and it started and ran great. I now have two extra Bosch coils and two extra Bosch 0 227 100 111 modules. I also have an extra Bosch distributor. The problem of buying used electrical parts can be a problem if they do not work and that is why I purchase used parts on eBay. I can always return the part and get a refund but, I usually have to pay for shipping.

That should be a lifetime supply of critical ignition parts.

I have purchased many Milano parts because I knew years ago that you needed them in order to drive the cars. I buy new parts as much as possible and buy used parts from Alfa Parts Exchange, ABB, eBay and other sources. I still want to buy a new Giulia QV because I can buy new parts from Alfa and the car comes with a warranty.

I just received one more ignition module attached to a Bosch coil. I was able to start the Milano with the latest module and coil. I now have three modules and three Bosch coils. I had only one working module two weeks ago and now have three spare modules and coils. I thank Larry at Alfa Parts Exchange and eBay for finding another three modules. This is a good example about finding parts a 30 year old Milano.
