Idle Adjustment
This procedure is a general recommendation, intended to help you tune up your Pro-Flo
®
system.
NOTE:
In manual transmission cars, this procedure must be followed with the car in Neutral and with the clutch pedal pressed. In automatic
transmission cars, this procedure must be followed with the car in Drive and with the brake pedal pressed.
Idle Calibration Procedure
• Prior to idle calibration, you need to have completed the "System Start-Up" procedure
• Warm up engine to at least 175°F.
Idle Control
• Using the calibration module, Select MISC. MODIFIERS and, Set Idle Control OFF.
Set Idle Mechanical Stop
• Set the mechanical stop screw so that idle speed in park/ neutral is 50-100 RPM higher than you want the engine to actually idle in gear
with the idle control turned on. Typically 600 - 1000 RPM depending on the installed camshaft.
• We find 650 RPM a good idle for our #3512 (with Performer-Plus camshaft) calibration.
Set Idle Fuel Modifier and Idle Spark Modifier
• Using the calibration module, Select MISC. MODIFIERS and adjust Idle Spark and fuel Modifiers to obtain best idle quality. Idle quality
will vary with engine design. Fuel and Spark setting will interact, particularly when you approach best settings.
• You must establish a smooth idle prior to using Idle Control. Otherwise, the RPM will surge when Idle Control is turned on.
Save Calibration
• Re-check that the TPS setting is 13 Degrees.
• Using the calibration module, Select MISC. MODIFIERS
• Set IDLE CONTROL ON. Set TARGET IDLE to the same RPM established by the idle stop screw.
• Save calibration settings to “A”
