told us. The company also has introduced new fuel pressure regulators for EFI applications that allow base pressures up to 120 psi, and new versions of its A1000 regulators with a smaller, more sculpted body and a choice of -6, -8 or -10 AN ports in all-black anodized finish. “We are also seeing increased use of our belt and cam drive mechanical pumps for very high-horsepower EFI applications, with pumps available up to 32 gpm, and compatible regulators with port sizes up to -12 AN,” Fickler said. Higher flowing injectors using larger electric and mechanical fuel pumps require high-flow capacity pressure relief valves, fuel filters, and large -12 AN size fuel rails, said Brad Cauzillo of Kinsler Fuel Injection in Troy, Michigan, adding that his company’s K-140 pressure relief valves are well-suited to these high-flow capacity demands. Cauzillo pointed to Kinsler’s valves’ For ECUs and EMS applications, several sources noted that wiring accounts for some of the most common challenges encountered by customers with EFI systems. Because competitors may not be able to fully handle these complexities, “this presents opportunities for shops that specialize in this area,” one source said.

Sam Barros explained, “With direct fuel injection, we have moved the fuel injectors from the intake ports into the cylinder itself. That means that most of the fuel is now evaporating inside the cylinder. Because the fuel evaporates inside the cylinder, we end up with lower end of compression temperatures, which means there is now a lower likelihood of knocking to occur. “That then enables us to increase the FOR LIVE LINKS, VISIT PRI’S ONLINE JUNE ISSUE AT AEM Electronics Infinity ECU • Series 7 Infinity for total control and maximum I/O, Series 5 Infinity for total control with less I/O, and Series 3 Infinity for crate V8s and MEFI conversions. • Airflow model based (VE) tuning. • Flex fuel compatible and multi-fuel capable, featuring multiple boost control strategies, nitrous control, map switching, anti-lag/rolling anti-lag, no-lift shift, integrated engine protection strategies, drive-by-wire (excluding Series 3), variable valve control (excluding Series 3), plus much more.
