I was impressed my Maxi Sys Elite was successfully able to perform special function to reset alcohol % content to address rich running codes and very negative fuel trims , but in live data in multiple categories I was not able to find FRP (Fuel Rail Pressure PID displayed to see what the running fuel rail pressure was.

Later in day after the customer returned,  I tried  my old Centec MS609 equivalent Generic OBD code and data scanner and saw the Fuel Rail Pressure was indeed displayed on it.
