Nice thread revival batman!

Finally got one of these boxes; a 'medium price one' -- it's hard to know exactly what is the difference between all of them (if at all). I took the box apart to check what's in there, and yes there is indeed some active components, a PIC uC etc -- wether it /does/ anything is not clear.

Anyway, I've installed it, the instructions and the pic of @slyfox are pretty much enough.

Short test drive okay. I'm out for a long drive tonight, I'll see if it makes any difference, both on power and fuel consumption.
