Correct me fella's if I am wrong, but logically this would make sence right? If the ETC has a compression ratio of 16.3:1 and the ETH has a compression ratio of 17:1 that would make the ETH have an easier cold start right?
Here is my logic....higher compression=more heat since we all know how our engines run, more heat at start up makes it easier for that diesel fuel to ignite. correct?

keep in mind this if you were not to have the aid of the grid heater. I guess it should have the same affect if you were to use the grid heater....just at a lower temp.

 

I have know idea, but mine starts easyer than any other vehicle I have ever had. I have only been in temps down to about -5* celceus
