Here is version 1 of the system.
http://www.gadgets.co.nz/mjv/fiat/images/ign-v1_s.jpg http://www.gadgets.co.nz/mjv/fiat/images/ign-v1-7_s.jpg Needless to say it didn't work.
Being stubborn I didn't give up and buy a Toyota. Instead I built version two.

Distributorless ignition, version 2

After some serious thought I decided it would not be reasonable to use discrete ICs to design the ignition. There were just too many things I was not sure about with regard to the Jaycar ignition. What signals were produced, when, level-triggered vs. edge triggered, it was all a bit foggy. So I decided to use a microcontroller. This would let me fiddle with somftware and not have to design new boards each time.
It's based on an Atmel chip which I had to order from Digikey in the US - they don't seem to sell them in this unfashionable end of the world.
http://www.gadgets.co.nz/mjv/fiat/images/engine-3_s.jpg As you can see it's housed in a die-cast box where the old ignition used to be. You can just make out the 20 pin Atmel chip and a D9 connector. Yes, my car has a serial interface...
In order to decide which bank of cylinders should fire I use a cam sensor. This was mounted in front of one of the cam wheels. Tim at Fixations helped with the mounting of the sensor as well as fitting 'timing marks' onto the cam wheel itself. The timing for these does not have to be exact as I only need to know what 'quadrant' I need to be in. The sensor is just visible in the photo below (right hand cam wheel).
http://www.gadgets.co.nz/mjv/fiat/images/engine-1_s.jpg The two coils I used are from a model of Holden which is pretty common in this part of the world. As it turned out, the low voltage connectors on the coil are very close to, but entirely different to any sort of commonly available connector. It's a female connector so there's no easy way to fudge something. I went to Holden to enquire about the mating part, but of course it costs $600. It turns out it's more than a connector; it includes electronics too. Gee wizz, that's just great. Staring at the coil for a while I decided to fabricate a connector. Hanna helped, and cutting and filing at small pieces of brass for some time we had some really nice mating connectors.
http://www.gadgets.co.nz/mjv/fiat/images/engine-2_s.jpg All hardware installed I set about writing the software. Some experimentation was required in order to get the system running. It's amazing how many parameters there are for such a simple system. Also, it's amazing how loud it can be when an air/fuel mixture explodes at the wrong time (say in your exhaust) when you are testing in the garage. After much spluttering, coughing, head-scratching and thought I finally reverse-engineered the Jaycar system enough to figure out what I needed. A few versions of code later (presently the car runs MartinOS V1.03) it burst into life. Yippee!
It ran pretty well for the next few months. A nice professional PCB is in the works to replace the hand-made in the garage at home one I have been using.
Then bad things happened
:thnkr::fun_36_1_7[1]:

Where is all the water going?

MAD

After changing to the distributor-less system the car was pretty reliable. The only thing I noticed in the following months was that it would consume spark plugs a little more regularly than it used to. Number four always appeared a little discoloured. See the photos below; left is a plug from number one. Right is a plug from number four.
http://www.gadgets.co.nz/mjv/fiat/images/plug-1_s.jpg http://www.gadgets.co.nz/mjv/fiat/images/plug-4_s.jpg I had changed a stage hotter in plugs in an appempt to prevent this fouling. It kind of worked, but not very well. The car kept consuming plugs. The plugs above are NGK BP5ES from memory.
For what it's worth, many people with older cars have problems with the current fuel in New Zealand. It causes fouling quite badly so it is quite common to run slightly hotter plugs than in a country where decent fuel is available.
After some time without any body repairs that dreaded rust started to appear. So I took the car in for work. I'm amazed how a new car gets repaired in a day or two, but as soon as the car is old, the panel-beater gives it lower priority. Anyway, after being passed over for a few weeks, the car is finally ready. So I'm driving home and the temperature rises above where it usually sits. I stop and check the water level in the radiator. Oh no, there is no water... This reminds me of another story (there are so many) about a colleague of mine who had his car worked on. When he picked up the car he noticed that the temperature went up higher than normal. He stopped to have a look under the hood and noticed the radiator was missing. Yes, the garage had removed it and not replaced it. Good 'ol NZ eh.
My car still had its radiator, just no water. So had the water been drained or had it disappeared by another means? Well, in the days that followed I kept a close eye on the water level. It appeared to be disappearing. Oh no, head gasket? The oil looked fine though.
Of course this happens when your mechanic takes a three month leave to go to Europe. So it's off to another mechanic, in fact the guys who service my 911. As it turns out they pressurise the system and water blasts out number four spark plug hole. Oh dear.
They remove the head and find a leak between the water jacket and the inlet of number four. Number four. That explains it. Looking at the rather clean valve on number four it's possible to see I've been running with water injection (unintended in this case).
http://www.gadgets.co.nz/mjv/fiat/images/head-1_s.jpg http://www.gadgets.co.nz/mjv/fiat/images/head-2_s.jpg http://www.gadgets.co.nz/mjv/fiat/images/head-3_s.jpg http://www.gadgets.co.nz/mjv/fiat/images/head-4_s.jpg Since the leak is in a low-pressure section I decide to have it welded up. The head will then be skimmed to make sure it's flat again. All the Abarth gasket bits (130TC) and new bolts are ready. Just have to wait on the engineering shop now.
I took some photos of the car without its head. It really does look poorly.
http://www.gadgets.co.nz/mjv/fiat/im...eadoff-1_s.jpg While the head is off awaiting work I decide to have hardened valve seats installed. There is a bit of a story behind this. A few years ago the government stopped the sale of leaded petrol in New Zealand. This of course was a bad thing for classic cars that rely on the lead for lubrication. As a band-aid, most garages started selling a fuel additive called Valvemaster. This is added to the fuel tank each time you fill up. It's a hassle of course to do this. The price of Valvemaster has also been rising steadily. I've paid NZ$2 (about 1 Euro) per Valvemaster at some garages. One shot does 20L of fuel. The alternative is to replace the exhaust valve seats with hardened versions that mean the car can run on unleaded fuel without any additive. Less hassle that's for sure. Since the head is off the car it makes sense to do it now.
Here is a photo of the carbs as they lie on the bench at Autothority.
http://www.gadgets.co.nz/mjv/fiat/images/carbs-1_s.jpg We're about to start week five since the car was taken in. I'm trying to remember what it was like to drive. I think first gear is left and forward...?

حبيى واخويا الفاضل ادماير
من ناحية صورة الاسبراتير ومكانه
فى 132 نوعين نوع الاسبراتير العالى اللى عند الكامات وخصوصا الكامه اليمين ودا عندى دلوقتى واما جينا نشترى العربيه دى قعدنا ندور فتره على اسبراتير عالى ودا لان حصلت معانا حكايه
ربنا لا يكتبها على احد من قارئ الموضوع نهائى
وهى ان والدى من هواة ركوب 132 من قديم الزمن وهو بيركب عربيات من سنة 75 وركب 132 اكتر من 7 عربيات كان اولهم 77 زيرو وبعدين سنتين وباعها نظرا لسفره للخارج
المهم لحد اما انا بدأت افهم الدنيا يعنى كان عندى 4 سنين وقتها
كان عندنا عربيه 132 GLS 1800 بس كانت تحفه مفيش فيها قلم بويا لا برا ولا جوا
والحمد لله سكنا بيتنا الجديد وكانت العين لازم تيجى فى حاجه
والحمد لله جات على قد كدا العربيه يا سيدى واقفه فى الجراش لا بيها ولا عليها وكانت الصيانه الدوريه شىء لابد منه لحد ما فى يوم كان الجراش ليه باب من داخل البيت غير الباب العادى بتاعه
وكنت من عادتى انزل ادور العربيه وكان وقتها كنت فى 4 ابتدائى لقيت ريحه بنزين لا تخطر ليك على بال نديت والدى وقولته المهم هو بعتى مشوار وميبقاش غيره فى البيت واخويا الصغير كان وقتها عنده 5 شهور نايم فى الاوضه اللى جنب الجراش وهو لوحده مع العربيه
وساعة القدر يعمى البصر زى ما بيقولوا فتح الكابوت وبص ملاقاش حاجه قال انا كنت مفول وجايز فايظ التانك نزل شويه وقام مدور العربيه وهو مش من عادته يدور العربيه والجراش مقفول
المهم دور مفيش نص دقيقه لقى حوض العربيه كله نار لان السبب هو الاسبراتير الواطى اللى تحت الرداخ دخل فار وقرض خرطوم البنزين بتاع الرداخ والخرطوم فضل ينقط فى الاسبراتير لحد ما عماه
وكان ويله يطفى النار ولا يفتح الجراش ولا ينزل سكينه الكهربا ولا يأمن البيت المهم عما امن البيت طلع برا لقى باب الجراش طرشأ من السخونه والناس اتلمت من هنا وهناك ويحاولوا يطفوا لكن البنزين بيشم النار خلصم يجى 8 طفايات ولا اى شىء وبقى همهم الشاغل هو عدم انفجار التانك لان انفجاره فى دمار للبيت والدنيا وكلها جه جرار زراعى وشد العربيه من الجراش بخطاف حديد وطلعت برا وهى شديده الاحتراق واحنا اساسا كنا قاعدين فى طنطا لكن والدى بنى لنا البيت فى بلده عشان يبقى قريب من اخواته ودى بقى نقطه ليها مغزى جه جرار محمل بمقطوره رمل وفضاها على العربيه ومع الطفايات قدرنا نسيطر على الحريق تماما والحمد لله التانك ما نفجرش وانا كنت وصلت ساعة ما طفو العربيه وكانت عباره عن قطعه من الخرده أكلت النار كل الاجزاء وسبحان من بيده كل شىء النار توصل لحد التانك وتلاقى بوية العربيه زى ما هى وبقيت الاجزاء على الحديد
وبعد اما انتهى الموضوع تذكر والدى اخويا الصغير اللى نايم بالداخل وسبحان من بيده كل شىء لا يصحو اخى منه نومه وسط هذا القلق والاضطراب رغم اشتعال النار ببعض اجزاء من العفش بالداخل وزياده الحراره
لكن هى ارادة الله ولا احد يستطيع ان يتدخل فى ارادة الله
ولذلك اصبحت لا احب الاسبراتير الواطى تماما
ونصيحه منى للاشخاص الذين لديهم اسبراتير واطى التأكد من سلامه الخراطيم يوميا وضروره عمل عزل تام لها لكى لا يحدث بها اى خلل ويحدث ما لا نحمد عقباه
انا لم اسرد القصه لاخذ شفقه او نيل احسان من احد
ولكنى سردها رغم اثرها النفسى السئ على
ولذلك اصبحت الان اراجع كل وصلات الكهرباء والبنزين يوميا
واردت ان انبه اخوتى الكرام لهذا الامر ومدى خطورته

الحمد الله انك سليم واخوك والوالد الكريم وفمليون داهية العربية حتى لو كانت جاجوار !!
برضه الاسبراتير فين ؟؟!!
