Could someone post the proceedure from the manual for setting up the tech2 to graph the fuel pressure regulator. I seem to be computer challenged today and cannot post a usable file.....anyway in my manual it is on pg 6-3116 to 6-3118 and has 3 plots, 1 for an engine w/ 0 miles, 1 w/ 26k miles and an example of a bad graph w/ sharp fluctuations. thanks!! ......Bill

plug in the tech-2 and build the vehicle. Chose powertrain, then data, engine data and engine data 1. on the soft keys there is a key for live plot, push that and then high light actual and desired frp. it will have an * besides it when selected by pushing the enter button. Then push plot. This should do it, hard to remember if I am missing anything with out having it in front of me...

Do everything Eric said and adjust the min/max.


Set up the scan tool in the following format:<LI type=A>Select the Data Display on the scan tool. <LI type=A>Select Engine Data 1. <LI type=A>Select the More softkey 2 times. <LI type=A>Select the Live Plot softkey. <LI type=A>Select the Engine Speed, Actual Fuel Rail Pressure, and Desired Fuel Rail Pressure parameters by highlighting each parameter and depressing the ENTER softkey. <LI type=A>Select the Accept softkey. <LI type=A>Select the More softkey, then select the Change Min/Max softkey.
Select the More softkey, and adjust the parameters to the following Min/Max ranges:

The Engine Speed Min/Max range is 0 to 1000 RPM.
The Actual Fuel Rail Pressure Min/Max range is 1.0 to 160 MPa.
The Desired Fuel Rail Pressure Min/Max range is 1.0 to 160 MPa.


Start and idle the engine.

yeah, what he said. Thanks Eric
