INSTALLING THE CPU MODULE
Note: Examine the new CPU module for damage. Make sure the battery on the
bottom of the module is properly seated. It the battery has come loose, contact
Dynojet.
1 Insert the nuts you removed earlier into the new CPU module (two on each side).
2 Secure the CPU module to the stack base.
2a Set the CPU module on the stack base.
2b Line up one of the front nuts with the stack base and secure with a
button-head screw.
2c Line up the remaining front nut with the stack base and secure with a
button-head screw.
2d Cover the back openings on the CPU module and tilt the module until the
nuts slide down and hit your fingers.
2e Using the allen wrench, slide the nuts until they are aligned with the holes
on the back of the stack base and secure with button-head screws.

3 Carefully align the top three modules on the CPU connector.
Be sure to place one hand on the stack base as you are replacing the top
modules in order to ground the modules.
4 Gently but firmly, snap the two module sections together.
5 Make sure the grounding strap slips over the top right nut on the CPU module.
Note: Do not secure the grounding strap at this point.

6 Verify each module is being recognized.
Note: Be sure to check for proper module communication before securing the
grounding strap and cable ducts. This will make it easier to troubleshoot and
reposition the modules if needed.
6a Attach the 9-pin serial cable from the PC to the RS-232 socket on the CPU
module. Refer to Figure 1-8 for cable placement.
6b Attach the 3-pin power plug from the power supply to the CPU module with
the flat side facing down. Refer to Figure 1-8 for cable placement.
6c Plug in the power supply to the power source. Turn the power switch on at
the CPU module. Verify that the green power LEDs glow on each module.
6d Use Dyno Find to verify each module is recognized.
• Open Windows Explorer.
• Double-click dynofind.exe located in the WinPEP folder (C:\WinPEP).
• Click Search.
• Verify each module is being recognized. Your CPU module number will
be different from the one used in this example.
Note: Be sure any additional modules, such as the Air/Fuel Ratio module, are
being recognized by Dyno Find.

6e If the top modules are not responding, turn off the power and separate the
top modules from the CPU module. Make sure all the connector pins are
straight and carefully replace the top modules.
6f Repeat steps 6c through 6e until all of the modules are recognized.
7 Once all of the modules are recognized, turn the power off.
8 Using the No. 10 torx wrench, tighten the top right screw on the back of the CPU
module to secure the grounding strap.
9 Replace the cable ducts on both sides of the CPU module.

10 Attach the cables removed earlier to the hardware stack. Refer to Figure 1-8 for
cable placement.
• Attach the 9-pin shielded serial cable from the PC to the RS-232 socket on the
CPU module (if not already connected). Tighten the screws.
• Attach the 25-pin shielded cable from the dynamometer to the Dynamometer
Input/Output module. Tighten the screws.
• Attach the 9-pin connector from the hand-held pendant to the Dynamometer
Input/Output module. Tighten the screws.
• Attach the 3-pin plug from the power supply to the CPU module with the flat
side facing down (if not already connected).
• If you have an Air/Fuel Ratio module (not shown), attach the cable and tighten
the screws.
• Be sure to attach any additional module cables you may have to the hardware
stack.
