I don't believe there is any "best economy" setting for the AMM, but have found that about 365 ohms gave good emissions test results on 240s that were in an otherwise good state of tune.

If you do the Base Idle setting (link below), it's 700 rpm with test point grounded not 725. The ECU should then bring it up to 750±20 rpm when the test ground is removed. This is according to Volvo Service manual TP 31003/1 for B230 engines, 740/760 from 1985 up.
