Testing The Sensors

Before starting the engine, test all sensors.

1. Turn the key to the ON position with the Calibration Module connected. The display will read:

NOTE: A vacuum reading of other than 0.0” Hg may be displayed depending upon barometric pressure and air temperature. At extreme
altitude, the vacuum reading may be as high as 5.0” Hg.

2. Push the UP ARROW key once to display.

NOTE: The water and air temperatures displayed will vary depending on ambient conditions. The system voltage will vary depending on the
condition of the battery.

3. Move the throttle to test the Throttle Position Sensor (TPS). The TPS reading should vary depending on throttle angle.

4. If the Calibration Module displays any error messages, refer to the TROUBLESHOOTING section of this manual and the User’s Manual.

NOTE: If the calibration module goes blank while cranking, the system is losing power. Check the Pink/Black wire attached to the 3 Amp
fuse for +12V power with the ignition in the crank position and the run position for proper operation.

Starting The Engine

After the fuel pump has been primed and the engine has been started, bring the engine speed up to cam break-in RPM (physically holding the
throttle at 2000 to 2500 RPM for 10 to 20 minutes), following the cam break-in procedure as described in the CAMSHAFT section.

Timing Adjustment

Use a timing light to re-time your engine. The following steps must be performed after the induction system has been installed and the distributor
has been converted and re-installed. Refer to the INDUCTION SYSTEM and IGNITION SYSTEM sections of this manual.

1. Remove spark plug from Number One cylinder.

2. Remove coil wire from distributor and ground it.

3. THIS STEP REQUIRES TWO PEOPLE OR USE OF A REMOTE STARTER SWITCH. While one

person rotates the engine by slowly bumping the starter, the other holds his finger over the
Number One plug hole until compression is felt.

4. Continue to bump starter until timing mark on the crankshaft pulley shows approximately 10

degrees Before Top Dead Center.

5. Position rotor to approximately align with the Number One cylinder plug wire terminal in

distributor cap. Check that the leading edge of the narrow tooth on the shutter wheel (as the
shutter wheel rotates clockwise) is centered in the sensor. Refer to the IGNITION SYSTEM
section in this manual for details.
