Resetting TPS baseline with PCV? powering ecu w/12v battery

Can i reset my TPS baseline or at least get the baseline voltages with my PCV if i power up my ecu using a 12V battery? If so, anyone know where the connection is to hook up a 12v to power on the sled. and how to do that? I know you can check the tps idle voltage with your power commander when the sled is running, but i wanted to reset the baseline first and i dont have a TPS tool.
THanks

you can get the baseline voltage but you cannot change it. you can do it with the 12v battery. down by the exhaust valve solenoid you will see 2 flat white plugs. One has 3 wires going to it and the other has 2. you will want the plug with 3. put the possitive to the orange wire and the negative to the other wire on the outside (can't remember what color it is. i think it is black with a blue stripe). this will power up the ecm. make sure you do not touch the power cables together or your ecm will go poof.
