How to set timing on 1987 D100 with 3.7L six?

My 1987 D100 has a slant six, 1 barrel carb and a computer. How does one set the timing since it is controlled by the computer? I know on some of the newer cars you have to unplug certain connectors, etc. What do I need to do to this one?

Thanks,
TD

Get it warmed up, make sure it's running at normal idle speed, then throw the timing light on it. Adjust as necessary, should be a sticker under the hood saying what to set it at. My 80 says 12*.

Lol better be gold-plated vacuum line I think he meant the computer.

You can set the initial timing by turning the distributor, like most distributored engines.

Speed is correct.....

You can set the INITIAL timing on most anything that still has a distributor...
Even completely computerized/FI engines.... And the initial timing will have an effect, even after the computer takes over.... Mostly with starting/idle....

Of course, if you get the dist really out of wack, even the computer can't make up for it...
