This is done by selecting this menu option and entering this factor There is no decimal shown so you will be entering this value as a three digit number For example 1 05 will be entered as 105 0 95 will be entered as 095 subtracting 5 Likewise if fuel mileage reading is known to be off by 5 say the gauge is reading 5 low t u v w x y enter a correction the same way 105 As with the shift light entry field you will use the left button to change the digit above the cursor Hitting the right button will move the cursor to the next digit After the last digit is entered you will return to the main menu The factory default value is 100 representing 1 00 or no correction factor Also if the MAF sensor has been recalibrated or replaced with one sized differently this correction factor which is based on the new sensot s scalar can be used to compensate for this change For Example and SCT BA2400 MAF sensor has a scalar of 0 47 To correct for this you ll need to enter 213 representing 2 13 which is the same as dividing the MAF reading by 0 47 An SCT BA2800 has a scalar of 0 40 so 250 would be entered in this situation same as dividing MAF by 0 40 Altitude Enter your altitude elevation in feet as a 4 digit number For example 700 above sea level would be entered as 0700 2500 would be entered as 2500 This entry is used in some of the calculations to improve their accuracy Not all gauges wil

9. VEHICLE SPECIFIC NOTES 04 Pontiac Grand Prix A common mount for the Interceptor is in the top left vent next to the steering wheel If mounted here hot air cannot be blown directly on the unit for extending periods of time Insulation should be placed behind the Interceptor if hot air is blown through this vent when the heater is on for example Some parameters are not supported by all vehicles but they may still be displayed as a dummy value in place of a real one Certain manual transmission cars will display a false transmission temperature and some V8 s will display an erroneous oil pressure for example These dummy values may be obviously incorrect or may look normal at first but never change If both parameters being displayed are analog inputs the gauge will not turn off immediately when the car is shut off This is because the gauge is not scanning the car and does not know it is off After 10 minutes the gauge will check the car s status at which time it will see the car is off and turn itself off Miles per gallon and Injector Pulse Width cannot be monitored using the annunciator function 97 Pontiac Grand Prix Ignition advance will be displayed as a negative number 2000 2001 Grand Prix There has been a few reports of the Pass Key III system rejecting the keys when this gauge is plugged in when the car is started in extremely cold temperatures below 20 degrees F Therefore it is recommended to unplug the gauge befo

28. u where you will select Cyclic Scan You ll then enter a scan mode where the parameters you selected will cycle in their predetermined amounts of time You ll need to experiment with the number of scans because scan rate and the vehicle itself will effect how long each scan takes If the parameter list in Setup is changed the Cyclic Setup must be completed again e Cyclic Time Choosing this will allow you to enter a number of scans time between screen parameter changes in cyclic scan mode f RECORD Upon selecting record you will initially be asked which mode to record in normal Scan or Cyclic Scan The unit will return to the selected scan mode except the first letter of each field description will be replaced with a square block to indicate that record is active You may notice that the gauge is scanning much faster in this mode Once the throttle position reaches 50 or higher the unit will automatically start recording the displayed data for approximately 45 60 seconds When recording begins the display colors will invert as an alert The recorded file will be saved for replay until record is selected again and the proper record conditions are met The new file will overwrite the old The Interceptor will maintain the file even when powered down If in record mode you wish to return to normal scan mode access the menu screen and select record again This will disable it until selected again via the menu Recording fuel econom
