1. With the key in the on position and the PC connected to the ECU, view the dashboard
tab in Pro-Tuner and verify that the intake air temperature and engine coolant
temperature indications make sense (indicate near ambient if the engine is cold).
2. Verify that the manifold absolute pressure (MAP) sensor indication makes sense (reads
near 0" vacuum).
3. Open and close the throttle and verify that the TPS % indication reads zero at closed
throttle and 100% at wide open throttle. If not, repeat the TPS set points procedure
outlined in the previous section.
4. Save the calibration by going to "File" and choose "Save Current Calibration to Disk".
Choose a filename and save the file as a baseline.
5. Verify correct fuel pressure (40-45 psi).
6. In the "Maps" tab, Click on the "Toggle Closed Loop" button to disable O2 feedback for
initial setup and tuning. Verify that the "Enabled" indicator is dark and not turned ON.
7. Go to the "Tools" menu and choose "Start/Warmup Settings".
