i jsut placed my online order for my 06 H3 I did the loaner program. I failed to mention that I want to have the cooling fan come on at a lower temp. Do they program that standard? I am a little nervous I hope I did the right thing.

 

I'm assuming you mean the engine radiator fan...It's not electric, so it can't be programmed, it is engine driven...works when it wants to thermostatically

 

Ok I thought I was told sometime that Alvin could make your engine run cooler like 160 or something but I may have been dreaming. Man you are fast on the reply thanks alot. Will I notice any fuel milage increase with the PCM?

Also before I get flammed from someone I will be taking pics this weekend and uploading them lol

 

The mileage improves over time..I've only had mine on since the tune about 400 miles now, but I sense an improvemnt from times before on how many miles I get before I fill up again..seems I can go longer between now

 

u can change the theromstat out to a cooler one like a 180 maybe down to a 160 but
napa or autozone are not showing one at any heat range for the H3 or colorodo
