H&S cold protection

[Davemc]

Can anyone explain to me how cold protection works on the Mini maxx, and how to set it up?

I have my COLD Coolant set to 160d, so it's using the No Power tune until the coolant temperature is up to 160d+.

To use the cold weather protection just go into the defueling settings an find "Cold Coolant" and set a temp you want the tuner to use as your switching point. In a nut shell, by setting this it won't let you run any tunes that add horsepower until the preset coolant temp is reached. Once it's reached, it will switch back over that what HP setting you have it on. It's easy as pie. I also set mine to 160*

[Davemc]

so "Defueling" means no tune? that word has confused me on here a few times?

So I am guessing that the cold protection would be a very good thing mostly for us that live in the north?

No, defueling means the truck cuts back fuel being sent to the engine to prevent damage.

[Evo B]

I should clear up the confusion made by my last response. What strokinpower said is true, typically the term "Defueling" means the ECM is cutting back on fuel to stop engine damage. In the case of H&S's "Cold Coolant Defueling" setting, I believe they are just calling it "defueling" to make things easier but what they are actually doing is stopping the tuner from adding HP until the coolant temp is reached. It is probably easier for them to just stick this feature under the "defueling" catagory instead of writing in another one somewhere in the tuner itself. The tuner will display right on it that no power is being added until you reach the coolant temp you set as your "Cold Coolant" switch point. Hope that clears things up.

[Davemc]

yes that makes more sence, Thanks Evo B

So it is better to run with no tune untill the truck is warmed up?

[Beene]

This sounds like a good feature. Are H&S the only guys doing this? Spartan? Bullydog? Any one else?

[Davemc]

I have not heard of anyone else talking about this, but I am far from an Expert,
