CHAPTER 1 Installation 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. use the allen wrench to slide nut into place line up front nut with stack base Figure 1-6: Line Up Nuts With Stack Base 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. 1-4 CPU Module Installation Guide

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. recognized modules Figure 1-7: Dyno Find Window 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.
