The fans do come on when I turn the key and put it in run mode. Briefly that is. Also, it they would come on irrespective of whether the AC was in "EC" mode or not. IOW, they come on when you turn the key into the run mode.

I don't know about Lightman but there were 2 versions of the chip. The one they listed or the stronger version. Guess which one I got. When you drive normally, there is no smoke and it behaves nicely. When you hit the accelerator, it will smoke like a frieght train. Also it does seem like I picked up 1 mpg with this mod.

Benifits
Wife is happy.
1 mpg more
I get to smoke out a tailgater

Cons
Costs $325 which includes overnight back and forth
