Hey I'm running really rich with my lt10s base maps. I have been using a digital voltmeter to read afr with an innovative lc-1 wideband. I have the lc-1 programmed to read 10:1 at 1V and 20:1 at 2V so stoich is at 1.47V. I would rather just use the microtech screen. The lc-1 says it imitates a narrowband out of analog 1 but I don't think mine does even when I set it to default. Does an lt10s need a narrowband simulated 02 sensor? If I were to set air/fuel ratios to a corresponding voltage like I did with the voltmeter guage what would they be?

 

Get a proper wide band.
If your microtech isnt setup to accept a wide band signal your not going to get proper numbers from your LC1.

As for your other question.

If you were to assume 10:1 at 1V. and 20:1 2V.

Set your cruise ratios to 1.38-1.45V(5-20HG)

Set your Load no boost (00HG) to 1.2-1.3V.

02psi 1.2V
04psi 1.18V
06psi 1.16V
08psi 1.14V
10psi 1.12V
14psi 1.08V
16psi 1.04V
18psi 1V
20psi 1V.

If your voltage correction map is correct(for your LC1) those afrs should get you going till you get a descent afr meter.
