I believe I understand all of it other than the following.
"[ECM] 45693 - Fuel Pump Fixed Duty Cycle Mode: Master enable/disable for Fuel Pump fixed duty cycle mode." - does this need to be enabled or disabled?
If enabled.
"[ECM] 23003 - Fuel Pump Fixed Duty Cycle: The duty cycle used when in fixed duty cycle mode." - what does this need to be set to? available range is 0.00 to 1.00
"[ECM] 23035 - Fuel Pump Off Duty Cycle: Duty Cycle when pump is off." - what should this be set to? available range 0 to 100%
Also, should I have the fuel pump wired up inline with the FPDM (i believe the only way to have the fuel pump prime like normal) or should I completely bypass the FPDM (running all time when key is on)?
I do have the factory fuel rail pressure sensor installed and hooked up like factory would have it, with vacuum and boost being referenced to it.
