Leading, trailing line up to same timing mark
 

When I checked the timing, the leading was right on the mark, but the trailing wire also lined up with the leading mark. What's up with that? If I adjust for the trailing, then the leading will be off. Does the ECU control the leading/trailing time?


'86 non-turbo, suddenly running like crap.

im getting this directly from the 87 mazda rx7 n/a or turbo workshop manual.


ignition timing: 5^o ATDC for leading, and 20^o ATDC for the trailing.

if timing is off, turn the crank angle sensor to adjust.

if you want a picture of what the page says let me know and ill take a picture.
