Has anyone installed one of these chips. I bought one but the directions seem a little odd? It tells you to unclip the two wire plug from the IAT sensor, the connect their control module to the IAT sensor. Its says in capital letters LEAVE THE PLUG DISCONNECTED! Then to cover the ends from the disconnected plug. My question is how does the car computer read the performance chip if it is only connected the the IAT sensor and not the engine harness anywhere?

 

Check the "chip" and see what plug it has. Most likly you need to plug it into the harness and cover the sensor's connector. If not then you got ripped off. Most of those so called "chips" are nothing but a resitor that gives the computer a predetermined value. It most likely will not do you any good installing that "chip". I would return it and try to get your money back.

If you are trying to get more power from your engine then have the PCM retuned (reprogrammed) it is the ONLY WAY to get what you want from the PCM.
