I also have one of these switches and would like to control multiple functions based on switch position. Example is position 1 would be normal (flex fuel, boost based on ethanol content, 7200rpm limit), pos2 would be low boost (for rain and track days to minimize heat soak), pos3 for autox (increased rev limit to 7800), pos4 for valet (minimum boost, 3000 rev limit), etc...
So I'd wire in the switch to an open AN, set the cal table, and then can I set tables in each function (rev limit, wastegate, etc...) to all reference the same table?
