Default timing question

I was wondering if my 86 computer has a built in timing and if I need a timing light at initial startup? Any tips with this newer computer type of engine compared to older engines without computers?

Pete K to the rescue hopefully????

You set base timing with a timing light and the EST wire (to the dist) disconnected like any older engine, the computer advances from there.

6 BTDC is stock, I find that 8-10* works better.
