BTW, this thing connects to the air intake temperature sensor. I think all it does is trick it into thinking the air is colder, which will increase timing up to around 3deg. The ecu only increases timing there because it is less likely to knock at cold temps, so it can work more efficiently and make more power. When you add 3deg of timing across the board, you are begging for knock. This is just a theory since they would probably never tell what it is actually doing.
