Ditron 812D D-Jetronic Tester, Searching for instruction Options

[nordfisch]

Hi,
this forum was recommended to me... and this is really a great place for guys like me, interested in the D-Jetronic system.
We have a forum in Germany, German and English language "oldtimer.tips", too.
We are more conservative than you are, mostly just trying to find out everything about the system and how to repair the components. We are hobbyists mostly MB, but also BMW, VW, Opel, Porsche, Renault, Citroen, Lancia... all the car brands D-Jetronic was installed in.
I by myself designed a tool for re-adjusting the trigger points to the original values. Simple to be rebuilded if you have a lathe - I will send you a figure on request.

Now my own request:

Does anyone here own a Ditron 812D tester, too?





I own such a device, but without any instruction.
It once came to Europe with the instruction, but it got lost.
I bought the Ditron some months ago on ebay from switzerland - the seller told me he had bought it many years ago at ebay USA.

It's no problem for me to understand and use the basic testing functions, but this tester is not only a testing - but an ECU-simulating device.

I don't really need the Ditron 812D to diagnose or optimize my car - I own some other testers.
But because the D-Jetronic-system is my hobby, I would like to understand the additional function, i.e. what the manufacturer intended the user to test / adjust with it.

Hope that someone still has the instruction for the tester...
My tester has serial #119 - don't know how many were built at all.

P.B. "Brad" Anders described the tester: D-Jetronic Testers as being similar to the Janbo Model 112 he described more detailed.

Does anyone own the tester / the instruction?

Please help...

Regards
Norbert

Hi Norbert,

Brad Anders had that tester at one point, you might email him, he might still have it and the manual. I just have the EFI Associates 9100 (MPC) and 8100 (AFC) testers

Compliments on the VERY nice D-Jet website you have created, I will definitely spend more time on it.

I also build D-Jet (and L-Jet) FI wiring harnesses, and rebuild/recalibrate the MPS using new diaphragms available here in the USA. See my website in my signature below.

(IMG:style_emoticons/default/agree.gif) Wow, I just checked it out. Another great D-Jet reference! With your site and the sites I already go to all the time (Bowlsby, Anders) I may actually figure out how this damn system works, particularly the MPS. I may yet have a promising career waiting for me as a D-Jet technician someday.... (IMG:style_emoticons/default/smile.gif)

I need to learn more about your trigger points set tool. Trigger points are like the only thing I haven't replaced before. Is setting them correctly in place normally an issue?

Thanks for checking in Herr Nordfisch.

Hi,
it's absolutely no problem to replace the trigger-points-set because it is being adjusted not by the mounting-screws but by the sheet the points are mounted on.

Bosch said the trigger points are not adjustable at all- and people believed in this for about 45 years.
I had a trigger-points set I had misadjusted by myself many years ago, made some re-engineering and designed the tool I will introduce soon here in the forum. It has been well approved now on four continents...
