edgar lopez Posted April 13, 2015 Report Share Posted April 13, 2015 Â i switched from Powerfc to the G4 RX since i hears great things about it. but the powerfc was a bit easier to modify the injector settings. i read the manual but doesnt really say much.i saw a thread about someone installing larger injectors and this is what i saw. "You're thinking along the right lines, but what you want to adjust is your master fuel number. For example if you had a master fuel number of 15ms with your 320cc injectors it would go like this: 320/550 = 0.5818 (old injectors/new injectors) 0.5.818*15 = 8.7272 (ratio from above * old master fuel number) Better to be rich than lean, so I would round up to a new master fuel number of 9ms. You will need to substitute your master fuel number into the maths above to arrive at your new master fuel number. You definitely need to have it re-tuned properly, but this should get you a good starting point. The master fuel number is found in PCLink underÂ ECU Settings > Fuel > Fuel Setup > Fuel Main" and i have done that but the issue in running into is the the "fuel master" on the 13b rotary map is 14ms. Â this is what i found on my injectors secondaries with resistors on them Mfg. Part number on injector: 0280150846 - White TopInjector type: EV1, peak and holdFlow Rate: 1600cc/min at 43.5 PSIResistance: 4.5 OhmsVoltage: 8-15 Volts, Nominal 13.5 VoltsAmperage: Peak 4.0 Amps/ Hold 1.5 AmpsPressure: Min. 36 PSI (2.5 bar), Max. 101 PSI (7 bar) primaries Static Flow Rate: 80lb/hr = 875 cc/minDynamic Flow Rate : 18.6 mg/pulse 2.5ms PW, 20 ms PeriodCoil Resistance: 12 Ohms (This high-impedance injector will work with all factory ECM/PCM injector drivers)Connector: Bosch EV1Series: DEKA 4 ( DEKA IV )O-Ring Type: VitonCross References:Siemens FI114992Siemens 110324 i changed the settings from to saturated on Â the primaries and peak/hold. im looking for help with my injector settings.Â Quote Link to comment Share on other sites More sharing options...
