at what temp does 5.0 goto closed loop?

[jetuomi]

PKRWUD will probably nail this in his sleep (its awesome to have you on this board) but at what temp does the computer switch modes at? is it 195* (same as the thermostat?) or is it higher/lower?

and if you dump a bigger rad that keeps the car around 190-200*, but say closed loop comes in at 205*, then will the car EVER go into closed loop? or does it goto closed as soon as it hits 205* (irrelevent of what happens after that?)

also, does it make a diff what year the car is?
(94-95 vs. 87-93?)

thanks !!
