Pulse generator contacts

Hi I'm new on here, I have a VW Type3 that is fuel injected and I have had to adjust my pulse generator contacts using the tool I made to Volker's drawing, but I am experiencing problems when trying to drive the car slowly in traffic. I have carried out lots of test on the entire FI system and ruled out all of the components except the pulse generators. The test guide on this forum says that if I measure the dwell on these contacts that it should be between 135% and165% but my dwell meter measures angle in degrees, what degree angle do I need to be achieving please?
Thanks in advance Doug.

Hi Doug,

well you should mesure in degrees 135° to 165°. of a total 360°. If you want to measure %, you should divide 135°/360° = 37,5% .However it should be more important to measure 2 equal values of a rough size like that. ECU just triggers on closing edge of contacts.

Hi Volker, thanks for the prompt reply , just to clarify with my meter plugged on to the pulse generator terminals and the engine running my dwell angle number is 45 degrees but I am on the 4 cylinder mode of the meter and am I right in saying that there are only 2 cam lobes for the pulse generators so I need to double my dwell number?
This indicates my gaps are too big but they are equal for each pair.

Doug.

Hi Doug,

just measure % or put it to 2 cylinders.

Hi Volker,
I can only measure degrees angle not percentage and my meter only goes as low as 4 on cyl numbers so do I need to double my reading?

Thanks Doug

Then just double the value your instrument shows.
