[QUOTE="Rednaxs60, post: 228552, member: 4617"] Have been progressing the work. Injector information is vague, but with enough perusing you can piece together a picture of what you are looking for. Injector pressure is quite specific. It's the pressure across the injector and maintaining this pressure that is important. For my application, I want to maintain an injector pressure differential of 43 PSI across the injector(s). This is based on the fact that the injectors are flow tested at 43 PSI resulting in a flow rate of 280 cc/min. This flow rate is used to determine the required fuel in milliseconds for each rotation cycle of 720 degrees. The OEM fuel system pressure was designed to use these injectors at reduced fuel pressure and flow rate. This is a key element in what fuel pressure you use in your FI system. The OEM fuel injectors will work well with the new Speeduino ECU, but the VE (volumetric efficiency) table must be adjusted to ensure the proper amount of fuel is injected to meet the estimated air mass admitted to the cylinder. I have installed an adjustable FPR and upgraded the fuel system. Only issue is that I have found that these adjustable FPR may leak pressure at the lower fuel rail pressures. This is not an isolated issue with inexpensive FPRs. This is my plan to date. More to follow. [/QUOTE]
