The MicroSquirt® V3 is a fully-assembled surface mount technology (SMT) version of the MegaSquirt® fuel injection controller. The New V3 MicroSquirt® has a waterproof case as well as adaptive noise filtering on the VR circuits. The coil drivers have been eliminated from this version and Ignition outputs are logic level only. Non logic level coils can be used with the addition of EFI Source coil driver Part # CI-101.
These injectors flow 80 lbs/hr at 43.5 PSI ( 3 BAR ) and even more at greater PSI! In addition, these units are high-impedance. Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications. This allows you to use a larger injector than normally possible without hurting idle and low speed driveability. Adding to the flexibility of application, these units are high-impedance; making them compatible with most ECUs, while delivering the most flow available in a High-Impedance injector.
These injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures under conditions.
LS motor direct fit 3 bar map sensor.
EFI Source is now offering a "plug and play" 3 bar map sensor for the LS series motors. It directly replaces your stock map sensor, utilizing the stock port on your intake manifold as well as the stock connector.
