If the ecm "remembers " BLM & adjusts from reading the stored cells, What 'remembers' the settings for cold Start up, when in open loop & the ecm not adjusting ?
 
Not sure the question is understood. Are you asking about startup fuel?
 
Yes Jerryl , sorry for the confusion. If I run & drive my Rig around , then I park it and don't start it for another week, what tells the TPS & IAC to keep their settings ?

There is a constant 12V feed to store settings in the memory, similar to the radio. On a stock setup, the orange wire at the battery positive connection can be interrupted to erase the previously stored settings (memory).

Make sense?
 
Um ... Er .. Is it that the TPS & IAC are mechanically set & disconnecting the Orange wire just clears the Code memory ?
 
Some good info. here.
