J and S - J&S Safegaurd System
 
Manufacturer: J and S
Other Info: The stock car already incorporates a knock sensor, but it can be slow to react and in fact is ignored by the factory computer at high RPMs. The J&S system makes up for the stock systems shortcomings to provide you with the necessary protection.
Comment: The available Knock/Retard Monitor utilizes a ten segment bargraph to show the amount of retard, so you can visually see the engine's tendency to knock under those specific conditions. A Dual Monitor is also available which displays both the knock/retard level as well as the air/fuel ratio.
Applications: MY93+ Impreza
Vendors: Cobb Tuning
