Ive just scoped another DIS one on a Saxo and the other a Punto same sort of set-up the only difference being the Punto has got 2 seperate coils where the Saxo's are all moulded into one and im still only seeing 80 volts on the primary ??
The scope has setting for primary and secondary & also has max voltage setting in scope and DMM of 400v, If i select primary I cant see nothing on screen, I have to go out of that setting go to scope and then select 125v, set the trigger then have a play with the time\volts untill I can see a good wave on screen, I'll a pic of the screen tmorrow
There wasn't an issue with ignition on this car, the misfire was caused by something else.
Without being able to click on the picture you have attached & expand it its hard to see,the only thing i do see is turbulence in the cyl & a near enough straight burn line & an obvious switch to ground .
