Compression Ratio's

I'm looking at increasing the C/R of my 4A-GE however I'm not looking to upgrade from the stock ECU at the moment. I have a small port bottom end and a big port head. So I was wondering what the highest C/R I can run using the factory ECU. Any help would be greatly appreciated.

Sig wa??? Loss in your logic.

what judges the Compression Ratio per cylinder is size dimension of the cylinder, piston head, how good the piston rings are, and the stroke.

Your Factory ECU just balance the ratio of Fuel and Air.
