That'll just help reduce ERDTT. It works, I use it all the time, but I don't think it'll help the issue with the ECM deciding it still needs an EMM occasionally in the conditions we are having right now as the engine WILL still run in ERDTT, especially at startup.
Although I know how you feel about unnecessary use of gas...sometimes you have to let it do it's thing in the interest of keeping the engine longevity intact - you don't want your engine sitting with a bunch of water in the oil.
If you want to completely eliminate ERDTT (and the EMM's that will eventually come with it after enough of them) you may want to look into the defeat solutions out there.
