Problems with 914 2.0 ignition, 123igntion doesn work Options

[sebastian-914fan]

Hello,

after over 5 years of restauration for my 914 2.0 1973 the car is on the Road of germany again. I think it is very nice but I had to do much on the engine and the injection.

So now i want to improve the ignition and bought an 123ignition distributor. It is also available for cars with injection now.
So yesterday i installed the distributor, connected the red cable of the distributor with the new ignition coil checked the ignition with the timing LED, then connected the black wire with the igniton Coil, installed the cap, the cables and everything and tried to start the engine. But the engine did not start and there is no spark. Seems the engine gets fuel but no spark.
Now i reinstalled the old 009 distributor and the engine starts easily.
I posted my problem in the Forum of 123igniton and someone told me, that the ignition switch could be the problem and i should connect the distributor direct with 12v power source.
I guess i can take these 12v direct from the battery + instead of the ignition coil or am i wrong?

Are there any othe tips you may have for me?

Hope my english is not too bad and my new ignition will work like an new in the next days.
Thanks for help! :-)

Hi Sebastian and others,

I've dug up this thread with the search function and read it with interest since I've also acquired a 123 ignition with the Injection option for my 2.0.

I do have an additional question concerning the choice of advance curve maybe you or someone else can help out.

What I was wondering is which 'curve selection' you've made on the distributor and how you went ahead in timing it correctly?

Since the original distributor for a 73 2.0 is the VW 039 905 205 or BOSCH 0 231 174 009.
The Bosch code is mentioned twice in the manual, as curve no 1 and as curve no 9 (or A when I look in another manual of theirs).
Which one did you choose and why?

Also the max advance for a stock 2.0 is 27deg BTDC @ 3500RPM, the 123 has 22deg BTDC @ 2200 RPM. This would mean I have to make a new timing mark or buy one of those fancy adjustable strobes, or am I missing something?

Hope someone can point me in the right direction.
