SMC Map Voltage Clip
 

I was reading about someone having a problem with the map voltage setting on the smc. So I reprogrammed mine to make sure it was right. I was wondering what in detail this does. The more voltage = the more correction? Like could I use this as a way to lean my car out more?

if im not mistaken, it just limits the max voltage the map sensor will send to the ecu
