Reply to "Fuel Injection and Electronic Ignition for VW engines - Speeduino Style"

Pressure, I usually start at 45 psi. Injectors are flow rated at 100% duty cycle at 43.5 psi. You get more accurate control at 80% than you do at 20% so it's better not to oversize too much. The 17 lbs/hr ones I'm trying are only rated for around 115 HP. I figured I'd kick the pressure up a little if the duty cycles ran too high.
