I don't know if it would cause any real damage to either your computer or engine, but something like this is likely to only give you a few HP, and lower overall performance cuz the engine isn't operating at it's optimum. Additionaly, as alluring it may be to get a few hp for so cheap, it can be far more expensive if the thing does more damage than good. So, IMO it's not really worth it. PEACE. Tek.
No no, you got it all wrong. It goes on your intake air temp sensor and tricks the ecu into thinking that the incoming air is cooler. The ecu will then allow the timing to be advanced a little more. Here's a thread on it http://www.nissaninfiniticlub....istor
Here's what you can do, spend the 15 bucks on a cheap timing light and start filling your car with premium gas. Manually advance the timing a degree or two at the distributor.
