The TFS unit is one of our older Piggy Back units. It is no longer in production, but for the benefit of our customers who still use these units, we provide the list of features, wiring diagrams and software downloads below.

The TFS is intended for dedicated high volume fuel only applications for turbo or superchargers.

It drives a single injector (or dual 8 ohm injectors) from the combined mapping of throttle, RPM and manifold pressure. The system is small, economical and easy to wire up. It can work in multicoil applications.

GENERAL DESCRIPTION
The TFS is a smaller version if the TURBO FUELLER (TF).
It does most of the TF functions, except Ignition Output Mapping, Air Temperature Sensing, Dual Injector Drives

Instead, it is ideally suited for Turbo and Supercharger applications where only one injector is required in moderate boost applications. The existing ECU will manage the ignition (Knock sensing) and possible air temperature variations and the TFS will provide extra fuel when the existing ECU can't. In addition to the standard TURBO FUELLER, the TFS has some enhancements:

• Two complete fuel maps
• Learning throttle input
• Input level switching
• Up to 6 cylinder multi coil triggering

FEATURES

• Single screen map with Throttle, RPM, AMP
• AMP up to 1.5 bar positive boost
• Up to 8000 RPM mappable
• 1 injector outputs
• Protected software
• RS232 port for tuning
• 3 ignition trigger inputs
• Full injector open times
• Throttle calibration
• Two maps, possible for fuel variations
• Input blanking to avoid extra noise transitions
• Built in input filter
• Trigger level switching
