Buy MegaSquirt II fully assembled ($400).
Obtain an A14 or A15 EGI factory Datsun fuel injection manifold. Make sure it has the factory rising rate regulator and fuel injectors included and the factory throttle body.
Everything else may be removed from the manifold.
- if you remove the EGR passage, fit a blocking plate
- the only vacuum hoses needed are the one to the regulator, and one from the throttle body yo the distributor
With MegaSquirt you won't need the Datsun airflow meter. Instead, Megasquirt will calculate the air mass using a TPS and and IAT sensor.
- Obtain a 240SX TPS, remove the EGI TPS and bolt on.
- Obtain GM IAT sensor. Drill hole in your air cleaner-to-throttle body pipe, and hot-glue the IAT in place. Or use JB-weld. Threaded bungs are available if you want to get really fancy.
Wire up the Megasquirt harness
- 12V
- earth/groun
- fuel pump relay
- injectors
Obtain a dropping resistor pack, and splice into injector wires
