A bump to set the timing.Any progress?

quote Originally posted by jdv: A bump to set the timing.Any progress?

Some, I ended up pulling the engine so I could rebuild the cradle and suspension on the car. This delayed work on the DIS setup.
Here are some a pics of the sensor and bracket mounted to the engine. The sensor tucks in nicely between the water pump and the alternator bracket. I measure 14° of adjustment range. I had to file away a small part of one of the timing cover ribs to give clearance for a screw head.





The camera angle makes it look like the sensor cable is close to the belt. In reality it has plenty of clearance.
I will post the bracket outline soon.

OK, here are the patterns for the DIS sensor bracket. Print the pattern with printer scaling set to "none" or 100%. A scale is included to verify the pattern is printed to the correct size. Pick the file for the paper size you are using. The DXF file is for use with CNC equipment. I used 0.080" ( 2mm) thick, hard steel sheet to fabricate the part.
The usual disclaimers apply. This has worked for me. Your experiance may vary. The files are offered "as-is". You are assuming all risks from there use. So there.
Links are to an outside file service.

I like the fact that the crank POS sensor is in a convenient location. DIS is nice, but I still have nightmares about changing crank POS sensors on many cars. (Near an engine pull on some). If this takes off, I might be interested in getting on board. I like the idea of modernizing this very cool car... Keeping it up with the times is awesome. Almost like being GM research and development engineers.....

Thanks Gravity any specific sensor that you have ?

If you go to the parts store ask for a Standard Motor Products # PC19 crank position sensor. The mating connector is a Standard Motor Products # S-812.
-or-
At the junk yards look for a 91 - 00 Escort or Tracer. I know there are other ford engines of this vintage that also use this sensor.

I guess there will be no need for the original trigger wheel that you sent me the .dxf file for, eh? Do you have that wheel pic in a .jpeg filed to scale like you did the sensor bracket? This might be usable to help with the markings for the balancer. BTW, how is your setup working for you?

Gravitic have you done an tuning on this engine yet?

The engine is back in the car. It cranks over and fires. DarthFiero just finished burning the DIS enabled program into the memcal. I am hoping to have it running this weekend. I will post the results. Cross your fingers!

Success!
I received my freshly programed Memcal from DarthFiero on Friday. Plugged it in and cranked it over. Initially it would not start. Just fire and not run. It acted like the timing was Way advanced. The DIS module is sensitive to the polarity of the crank sensor signal, so I swapped the two wires at the plug that goes into the module. A correllary to Murphy's Law states that when given a 50/50 choice you will be wrong 90% of the time.
This time it fired up right away and idles perfectly. I have made a lot of changes to the car so I can't say what improvments I can attribute to the DIS ignition. I can say the DIS and 7730 combo has greatly improved the drivablity of my car. It is really smooth and no stumbles.

Very good work! It's nice to see someone make progress on this problem. Thanks for posting the files to help others.
