Genuine SplitSecond AIC1-6 supplemental fuel injector controller with EV6 (USCAR) connectors for use in 6 cylinder applications. This product is designed for close course racing and may never be used on public roads.

The AIC1-6 is a laptop programmable additional injector controller. It is programmed with the Split Second R4 engine management software included on CD or available for download here. It controls six high impedance injectors over the complete vacuum region and under high boost as well.

When connected to true tach signal of the engine, the additional injector can be set to pulse at the ignition rate of the engine. This insures even distribution of fuel to all cylinders.

The AIC1-6 is generally used with forced induction engines consisting of a turbocharger or supercharger. The AIC1-6 gives the user a convenient way to set the fuel mixture for proper air/fuel ratio in the boost region. The approach of running additional injectors is well suited for late model applications with ECUs that have very tight control over fuel mixture. The fuel system can operate completely stock in the vacuum region and the AIC1 can provide the additional fuel required in boost.

The AIC1-6 comes pre-wired with EV6 (USCAR) connectors. The R4 software is included on CD with this unit.
