DDK - Die Deutschen Klassiker

Who’s running one and they as good as the hype will lead you to believe. And is the Bluetooth one available for 912?

I am Yes and Yes

So looking into it, it would appear I would need a Tune+ 4-R-V-V which is same for a 912 as it is a for a type 1 VW. Is that right?

I have one in my 356 and like it a lot. Noticeable improvement in performance and consistency of running.
912 is this one:

I've got one in mine which is a typeIV engine, the bluetooth+ is great as you can alter the curve

Thanks both, inaglasshouse that appears to be same one I have said, is it?

If it is the cheapest on line are...........

I think the only difference is that the variant I linked to includes the spacer ring.

The ring is also available separately:

Have been running one on my 912 for about 6 years now, have not had to touch it in that time. Had several issues prior to that with ignition niggles.

Put one on my fuel injected VW Type 3 too, and runs really sweet, also eliminated some small ignition issues in an instant.

I spoke to the people at 123ignition for advice and they were super helpful before installing it on the Type3.

I got that spacer ring as well, but it had no benefit. When mounted it sat loose on the distributor shaft, so took it off.

Thanks all, sounds like it’s the way forward. How did you all get a starting point for the curve maps?

356/912 advance curve are on here taking the BR18 as the unit fitted as standard.............just plot the middle of what it shows is the norm as a starting point?

This post should help from the 356 Registry as they talk about it on their 912’s

Thanks all, have ordered one including the spacer ring. Hopefully will have my car running again soon!!
