got a vaux engine running wasted spark on a 60-2 wheel single coil

after messing around with the tacho out put today i think ive got the bug now so im sitting in my shed and i see a dis pak so my question is this

1. whats the pros and cons of running one of these
2. what changes would have to be made
3. if i do change over where the hell do i start

thanx

If it runs well with the existing dizzy probably just leave it alone!!

However, if you do want to go DIS, you've likely done most of the hard work already in getting the dizzy going. In general to change you would need to add a second VB921 spark output and tell Megatune that you have two spark outputs.

The vauxhall DIS pack I may include ignitors - I forget. If it does then you may not need the VB921 at all - just run off the LED (-) signals.

i havent got a clue about the dispak james i dont no if it has or not

mine got a cap and arm at the end of the cam not dizzy so to speek but the reason i wanted to change ( apart from haveing something to do ) is i go through a cap and arm every 4-5 months and that costs me £40 a time so get rid and use dis and problems solved hopefully !

That's still a dizzy.

Do some searching here and you'll surely find info about the Vauxhall DIS packs. Checking a Haynes manual might give a clue too. If the pack is represented as a simple transformer then use VB921, if it has a transistor symbol on the diagram then it includes an ignitor.

If the coilpack has ground, 12v and two signals in then it contains an ignitor. I'm pretty sure they do.

still searching ............................

looked over the loom and the dispak the dispak from what i can see goes straight to the ecu so its got to be controlled by the ecu as theres nothing else spark side so how would i go about wiring it up

i take it i can use most of my orig settings wheel decoder etc
