What do you think about this gadget.

This chip needs to be connected to the IAT. Does it tell the engine I'm cold so its ok for more fuel and it can go hotter? Where is the IAT? Anyways sounds interesting. They also have a thingy for the oxygen sensor too.

I say no...just the price alone scares me...

The chip in the picture is a $.69 "op-amp". What they will send you will be a $.10 resistor. It's basically a scam.

That's interesting. I wonder where the IAT location is on the E90.

By looking over the things they sell, a lot of the stuff is pretty legit, ie: simota intake. Although, a little overpriced and hp exaggerated...grossly. However, they also sell things like the turbonator.

Pic of the chip is not what is sold, but I wonder why they wouldn't just take a picture of the real thing.

I also did a little research and found a possible theory behind this IAT mod. Generally, it is to trick the sensor to detect at a lower temperature. See item #3 on the link below.

New to BMWworld but I've heard many say that this doesn't really do all that much.

IAT is integrated in the Air Mass Meter.... don't put ghetto mods on your bimmer. It'll only end in tears.
