ambiant air sensor
Turbobooster, the ambiant air sensor is located in the air inlet tube between the air filter and the turbo on the 86-87 GN. It tells the computer what the air temperature is out side the car. When I talked to the radiator shop they said that the 4 core I purchased was designed to handle high horse power engines and flow more air through the core. All I know is that it really works good, I can turn on my AC and kick in my turbo and it still runs 170. I could never get below 180 before. The reason you want an after market chip like the Ultra chip from Caspers is that is has the stock chip along with 6 different levels of modified chips, so you have every kind of modified timing you can handle. Each time you change a setting it puts in more timing and more boost with just the click of a switch. Also the stock chip kicks on the fan at 195 and the modified chip kicks on the fan at 170-175
