Characterizing fuel injectors for use with megasquirt2. These are accel 44lb injectors, tested at 58psi rail pressure. This test was with an 8ms pulsewidth and 10ms interval. Goal was to determine deadtime for low flow/idle conditions for an isntallation with 49psi static pressure. With manifold depression considered, 58psi net is a good approximation for idle conditions.

Results
Voltage Dead Time
13.2 0.681
12.0 0.782
14.0 0.540

Flow rate corrected for standard 43.5psi- 4462cc/min or 44.04lb.hr
