cutting off injection going downhill was [Vwdiesel] Why gasss cars

I guess can understand this whole concept.  It just seems counter  
intuitive to me!  I will just  need to find a good manual on the TDI  
injection process and work this out in my head.  I have witnessed the  
same kind of cooling process that you talk about.  I was towing a  
popup camper behind my 98 Jetta TDI through parts of New Mexico.  We  
climbed uphill for several tens of miles until we reached the town of  
Cloud Croft.  Then there is a long downhill section into Alamogordo.   
I simply put the car in 2 or 3 gear and we rode down the other side  
using gravity.  The EGT went to rest at the bottom of the scale and  
the oil temp went below 100 degrees.  My Geologist brain works in  
different ways from those more mathematically inclined so it may take  
a while to glacial move some new thought on this into my brain.   
Especially an old brain like mine.  :^)  Hayden
