[Diy_efi] Ignition retard

[James Seabolt]

Is anybody aware of a DIY ignition retard system I could build?

There may be more to it that meets the eye but I'm thinking it's possible 
to install a device between the negative pole on the ignition coil and 
control module and use a 555 timer chip circuit to delay the time it takes 
the ignition coil to collapse creating a retard effect. In order to switch 
from non-retard to retard mode, I could use a Hobbs pressure switch so when 
my turbo kicks in, it activates the delay timer. Then use a potentiometer 
to adjust the amount of delay.

Sounds simply but is it possible?
