ELECTRONIC FUEL INJECTION TIMING RETARD FOR NITROUS OR TURBO BIKES

The EFIR-13 and ERIR-13-02 Retard Modules allow the user to retard the ignition timing on the Hayabusa, all years.

This unit plugs right into the factory wiring harness, and is 12 volt activated. Hook it right up to your nitrous solenoids or a pressure switch on your turbo bike, and retard the timing to save your engine.

It is programmable with dipswitches from 0-16 degrees of timing retard, and also has dipswitches to adjust the build time from .1 to 3 seconds.

Never install solid core spark plus wires, as this will cause the retard module and the factory ECU to malfunction. The factory spark plug wires wires work perfect.

EFIR-13 Fits 1999-2001
EFIR-13-02 Fits 2002-2007
