Technocarb developed that ESIP (Economy Sequential Injection Package) as low-cost alternative to the SVIS conversion kit designed to supersede their EFS600 mixer-based alternative fuel systems. Now discontinued, the ESIP was not a kit or system but an essential parts package. Assembling the parts contained in this package did NOT result in an EPA-certified fuel system. The ESIP package could have been configured for both standard bi-fuel (LPG/CNG & gasoline) or special-order mono-fuel (dedicated) operation.
Technocarb ESIP Economy Sequential Injection Packages were designed for vehicles equipped with electronic combustion emission control and diagnostics systems (OBDII or EOBD), with a catalytic converter and oxygen sensors. Technocarb ESIP systems were installed on engines with multi-point fuel injection, sequential injection, semi-sequential or single point injection. This system was also designed for multiple displacement engines. Technocarb ESIP was also compatible with standard turbo charged engines; however, vehicles with high level supercharging may experience problems running with LPG or CNG. When properly installed and calibrated, Technocarb’s ESIP complied with all international safety, and most emission standards.
Technocarb ESIP sequential injection ECU controller may not have worked properly with engines having a duty-cycle (RENIX type) injector controller with 3 ohms or less PETROL injector coil resistance.
