It is critical to supply us with all of the information we need to properly tune your vehicle. Please
consider that if your log does not have the required items we may miss an important part of your tune.
This how-to will get your scanner config file set up correctly. You can download this configuration file
from http://www.pcmofnc.com/install/PCMofNC HPtuners Scanner Config.cfg. You will still need to
set up your wideband if you are equipped with one. If you have downloaded our ready made
configuration file you can jump to after step 6.
Adding Necessary PIDs
1. Open HP Tuners Scanner.
2. Open the table display - See Red Arrow
3. Right Click any empty slot in the table window. See Blue Arrow
4. Add the following available PIDS
PID List EngineIdleIdle Adapt STIT - Gen III Vehicles only

AirflowDynamic Airflow
Mass Air Flow (Hz)
RetardBurst Knock Retard

5. Close The insert PIDs Window.
6. Verify the PIDs you added are in the table display. See Red box. Order does not matter
Setup Wide Band AFR - Optional but Highly Recommended
If you have a Wideband installed in your vehicle we can import the readings directly into the log. This is
invaluable for tuning. A wideband O2 sensor reports very accurately your Air/Fuel Mixture. The
process is much the same as the steps above. We have found the autometer brand gauges to be the most
accurate with the best instrumentation amplifier. Both digital gauges and analog versions work very
well. It however is not in the list. See step 10 for custom wideband setup.
Physically connecting the wideband to your interface is covered very well in the HPTuners help file.
