Real tuneability for Fuel Injected Engines! For many years, riders with carbureted engines have had the luxury of easy fine-tuning. By changing carburetor jets they could "dial in" their engines to achieve maximum performance and to compensate for engine modifications. Fuel injection however, has presented a tuning obstacle for riders who wished to make performance modifications to their engines. With the stock fuel injection module, even a minor change like a different exhaust system can cause an engine to run erratically and could potentially cause engine damage. The S&S Variable Fuel Injection (VFI) module provides the ability to tune the fuel injection and ignition systems to maximize the performance of any fuel injected engine. While the S&S VFI system will give excellent results on stock engines, its tuning flexibility is essential when engine modifications have been made. Changes to the engine such as cams, exhaust pipes, headwork, increased displacement, or all of the above, necessitate changes in the fuel injection maps. The S&S VFI fuel injection module allows the tuner to realize the full benefits of engine modifications through correct tuning. Re-tuning the system with the S&S VFI module will result in improved starting, better driveability, and more power.

S&S Variable Fuel Injection (VFI) Module Features:

•Easy Installation – Module replaces stock unit and plugs into the stock wiring harness
•Easy Programming – Existing maps supplied by S&S can be loaded by anyone with a PC
•Flexible – Maps may be easily optimized to accommodate variations in individual engines. Easy Tune software is included with the module
•Altitude Compensated – Automatically adjusts for altitude variations
•Live Tuning – Make changes to maps while the engine is running
•Self Diagnostics and Actuator test functions
•Engine light can be programmed to function as a shift light
•Unlimited Programmability – The ProTune II software allows the creation of maps for Custom engine configurations for which S&S has not supplied a map
•Dual closed loop capability when used with stock O2 sensors or the S&S Closed Loop sensor kit
•Engine overheat protection
•Manual tuning requires ProTune II software in conjunction with an eddy current or other steady state capable dynamometer and an exhaust gas analyzer or air/fuel ratio meter for manual tuning

Note
: Due to the extreme range of control offered by the S&S VFI modules, they are only available from S&S Certified VFI Tuning Centers. Check the dealer locator on the Zodiac website at www.zodiac.nl to find a Tuning Center near you.
