Computer Upgrade for Nissans

The STILLEN Upgraded Computer adds 8-10% more horsepower to computer-controlled Nissans with no other modifications.

With the advent of precise engine management, via computer microprocessors, comes the ability (for those in the know) to increase performance by programming the microprocessor with a different set of instructions. This programming is stored and read by the computer's EPROM. The EPROM mount we provide is "gold socketed" to allow for chip replacement. This is ideal for those who will continue to upgrade with items like throttle bodies, porting, cam changes, nitrous, etc.

The Upgraded Computer is easily installed in less than 25 minutes and the package includes an ECU Upgrade and a stock chip (which may be reinstalled at any time).

Since your ECU must be socketed to receive the upgrade program, a 96-hour (4-day) turn-around time is possible if you don't mind the air freight cost you'll incur both ways. Specify exact year and model Nissan you own (California or Federal model, auto or 5-speed-equipped, etc.).
