Hello all,

I am thinking of installing an electronic ignition unit in my 1980 Saab 99.

Any recommendations or advice on this?

(I am in The Netherlands)

Thanks,
Richard.

It has to be Lumenition - their electronic ignition is just lovely, and
extremely robust.

This month's 'Retro Cars' magazine has a full HOWTO article about fitting
Lumenition's optronic ignition system. It looks soooo easy ..

Hi!

Thanks for the reply, I checked on one Dutch site and found this:
 Lumenition Optronic ignition
 Lumenition Magnetronic

What is the difference between these two types?

I can see the pricediff....:)
     Lumenition optronic ontsteking  Euro 305,00 incl
     LUPMA50
+
     Lumenition montage kit  Euro 27,50 incl
     LUFKxxx

That totals 332,50 Euro ......

and the Magnetronic version is about half that price?:

     MAGNETRONIC BOSCH 0231/4C/221   Euro 166,50 incl
     LUMTK001

Is the optical system that much better?

I would actually rather go for the magnetic version over the optical.
The optical ignition system is what Lumenition became famous for, but
magnetic ignition (Hall effect) has won the day on reliability.

Interesting. Thanks for the perspective :)

:-)

Look at it this way - of the modern cars left which use conventional
ignition (as opposed to DI type setups or other 2 coil/4 coil systems)
how many use Hall effect and how many use optical? I can't actually name
a single one that uses optical. It's not down to price, because the
price difference vanishes when you mass produce.

Thanks Paul, Grunff!
I did expect some feedback here, but am really surprised about the speed of
it...!

I think you just saved me some 160 Euro's... I was thinking the optical
system would be better (because more expensive? :-) ).
Free beer time? :-D

Thanks again,
Richard.

The optical system is the old system that has a separate box outside the
 distributor with the works in it. The magnetic one is a hall effect
  system that fits inside the distributor.
I have just fitted a Pertronix Ignitor Hall Effect system in my Lotus,
and it went in with just three screws in place of the pints. I assume
they do one for the 99. Got it for US$70 form Import Parts Specialists
of Idaho; they have a web-site, as do Pertronix. I will do my 99 when I
have finished the Lotus.

I have Pertronics in my '62 Buick. I also recommend it. If you do a
search on it, you will find some detractors, though. The way  see it is:
I'll keep a set of points in the glove compartment and if it quits, I'll
just put the points in and drive it back home.

Wouldn't it be possible to use an ignition from an early 900?

Hmmm...

Your engine is a B type engine, with the distributor driven off a lay
shaft. I don't think any B engined 900s came with electronic ignition
(could be wrong, but don't think so).

If this is the case, then you'd need to install the hall rotor and
sensor from a later 900 distributor into your distributor. This is
probably doable, but may need some machining of parts to fit.

In addition to the components inside the distributor, you'll need the
ignition amp and the coil (the coil is different).

So I guess the answer to your question is yes it is possible, but may
not be as easy as fitting an aftermarket item.

Surprise surprise!
I just found out that some of the 99's from 1984 had electronic ignition
off-factory!
Can anyone confirm that?

Now if I could just find one ....

Thanks,
Richard.

Whoops, sent the first reply by email instead of to the group.

The 99 with electronic ignition was a H type engine, The 99 and 900 B type
turbo has electronic ignition, but the parts are becoming hard to find. I
just might know someone who has some..............

It reminds me that many years ago I had an old FIAT 132 without electronic
ignition. I fitted a kit that didn't replace the distributor, but it was a
kind of electronic amplifier that took the current load off the distributor.
It worked brilliantly, if only I could remember the name. These kits were
quite popular in the early 1980's.

Don't Maplin sell something similar as a parts kit these days?

Yes, I've actually made up a few of those, and used them successfully on
a variety of cars including my old Combi Coupe.

But there's a fundamental difference between these and the Lumenition
products - with ignition amps what you do is use the existing points to
switch a transistor, which you then use to switch the coil. The
advantage is no points wear, faster switching time and better quality
spark. But it's not quite as good as doing away with the points
altogether, which is what Lumenition setups do.

Oh yeah, knew the difference. just pointing out to Johan that they still
exist, so if needed he could replace a burn't out one or add one to acar
that needed it.

So did I!!! The ignition amp with existing distributor was very simple to
fit, no fuss with new mechanical parts. So I thought I would mention it.

Hello,
Someone here has a "Sparkrite electronic ignition"  for sale ... it's
cheap.... and used...
but any good?

I have Newtronic units in my '72 Sonett and the '79 96 and a Lumenition
'ignitor' in the '77 96. Both types work OK.

> (I am in The Netherlands)

Me too...
I have bought the Newtronic units from the (then) dealer in Roodeschool. I
believe they are in Utrecht now. Check 'Automobiel Klassiek' (daar wordt in
geadverteerd).
The Lumenition unit came from Chip Lamb.
