With the OBD-1 cars, you should be able to tune it to the rich side so that the trims are bottomed, and in that area of the map the O2 trim is running about 60 - 80 or so. That way, when it goes into open loop for the 16:1 area, it will be a little richer than it wanted when it sets the O2 trim at 100.
