HELP WITH TIMING
 

I have 93 with msd optispark want to know what degree of timing would be best for performance would like any help

RE: HELP WITH TIMING
 

Old school teachings tell me, depending on elevation, 5 to 7 degrees.

RE: HELP WITH TIMING
 

if ya got the "tuneup specs sticker" under hood use that as a base then advance till ping then back off 2 degrees

RE: HELP WITH TIMING
 

Timing is ECM controlled on Optispark from the factory, not sure about MSD.

That's what I was afraid of...
This 'puter controled stuff really leaves me in the dark a lot of times.
Sorry I couldn't have been more help.[&o]

RE: HELP WITH TIMING
 

maybe i misunderstood with the msd. does it have a stand alone msd box [controller] it may have rotary switchs for adjusting timing

RE: HELP WITH TIMING
 

the msd optispark has a set screw that lets you adjust timing afew deg i have not messed with it yet wanted input first

okeedokee .a few ways to play with the timing. first check it with a t light and mark it down so you know where your base is. follow the how to on timing and advance it 2 degrees then road test it. most important is no "ping or knock" .come back and advance it all the way [it has 5 degrees max if that is your system] road test again .ya want no ping or knock. if ya get it back off [retard] 2 degrees. with a max of 5 degrees i doubt ya will hurt anything
