Step 6: Connect the Controller to the Wastegate
Locate the wastegate on your turbo system. Connect the appropriate line from the Greddy Profec B Spec2 to the wastegate actuator. This will allow the boost controller to regulate the boost pressure effectively.
Step 7: Final Checks
Before reassembling everything, double-check all connections. Ensure that the vacuum hose is secure, and all electrical connections are tight. Use electrical tape and zip ties as necessary to tidy up the wiring.
Step 8: Reconnect the Battery
Once you are confident that everything is installed correctly, reconnect the negative terminal of the battery. This will power up your Greddy Profec B Spec2 Boost Controller.
Step 9: Testing the Setup
Start your Datsun 240Z and allow the engine to warm up. Test the boost controller by gradually increasing the boost settings while monitoring the boost gauge. Make any necessary adjustments to ensure optimal performance.
