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 ??

Is there a preset in your scope for primary ?

The ones i capture are through a 20:1 attenuator & a preset probe because the 4000 has a max input of 100V, what is the max input of your scope ?

I know on my Sykes Smart there is a preset for ignition as it is attenuated internally.

You should be seeing more than 80V on the primary kick .

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
