if i got this right when ur car warms up u go into closed cycle right?

well my car seems to only have trouble after its warm, so can i keep it in open cycle?

i mean i drive a minimal amount to where its in that mode most the time anyway then just 1 mile of closed cycle...

but that last mile is hard to get from point a to point b, my temperatures jump up cause i either have to be decelerating or in to low of a gear for my speed, cause i cant accelerate at a normal rate, just really fast. or not at all and when going up a hill i cant even keep my speed
