Is this possible? i have heard you can adjust +/- 5 degrees by the flat head screw, but then some say there is no possible way to adjust timing. i want to run a little nitrous but dont want to spray without adjusting timing.
Thanks

 

Dont do it...just not accurate enough to be used for nitrous IMO

your sig shows you have the 6AL...MSD makes an add-on module to add timing retard to that unit

think thats the one

 

does this retard timing? From what i can see it only adv timing?

 

nvrm yes is does reatrd timing. thanks for the help! does this just plug into the 6AL?

 

yes it will install with your existing 6al per the instructions that come with the unit
