Hey boys,

Needing a hand I'm just finishing off my new turbo A15 build the engine is all built and ready to go the issue I have is limiting and having a good timing curve and spark to keep the engine safe and reliable.
My first thought was to just get my electronic dizzy recurved to limit advance but I want the best performance along with the safest tune.

I'm really wanting to buy a cb performance black box but the thing I'm wanting to know is will it work okay with an electronic dizzy and it says the dizzy must be locked.. Just wanting to confirm or know the best option for programable curve..

Whats the best way to lock out an electronic dizzy for a programable IGN

To lock the distributor timing:
* to disable vacuum advance: do not connect a vacuum line
* to disable mechanical advance: weld or epoxy the advance slots

Logic tells me that a vacuum advance unit should work the other way and actually retard timing when it sees positive boost pressure rather than vacuum therefore aiding in stopping detonation under boost whilst still giving more advance and better power on light throttle load as it was designed to do Z 18 turbos did something similar with their distributors
