Battery VCO Gain
• Sets slope of battery input over operating range.
Battery VCO Offset
• Sets level, or offset of Battery input over operating range.
• Battery Voltage is a linear increasing type input function.

Oil Pressure Gain
• Oil Pressure sensor input.
• Ohm sensor on engine is a direct, mostly linear function.
• Sets slope of oil pressure input.
• Monitor Engine Overview menu of EGCP-2 and compare to measured oil
pressure of engine with engine running at rated speed.
• Adjust gain for proper oil pressure reading while engine is operating.
Oil Pressure Offset
• Sets level, or offset of oil pressure input to VCO frequency.
• Set to read 0 psi in Engine Overview menu of EGCP-2 with engine off.
• Gain and Offset DO affect each other, so it is necessary to check
adjustments at both ends of the scale (0 psi to operating psi) if an
adjustment is made to either gain or offset.
