A3-TIPS AND 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 before starting these cars in these
extremely cold temperatures, and plugging it back in a few seconds after the
car is started. There is no need to disconnect the power wire though.
2000-2003 full size GM SUV’s and Corvette: Owners my find that scan
speeds need to be lowered to setting 3 or higher to prevent false error
messages on the vehicles instrument panel. These vehicles have extremely
high data volumes with slower than desirable bus hardware.
‘96/’97 V8 GM trucks: A smaller set of parameters are supported for these
vehicles. You may only see 9-10 as opposed to 20+ for later years.
Saturn Ion Redline/Chevy Cobalt SS: Only the 2004 Redline can be
powered through the OBD2 port. The 2005+ Redline and all Cobalt SS
supercharged will need to remove the jumper mentioned in step 5 of page 4
and connect the middle red wire of the 3 wire connector to switched 12v.
SRT-4/PT Cruiser: The standard versions will not display fuel economy or
calculate horsepower, you’ll want the “Pro” version for these features. The
analog inputs and shift light all work as described though. Chrysler also uses
a slightly different method of clearing DTC’s (Diagnostic Trouble Codes).
The clear a DTC, the ignition must be turned on, with the engine off. Once
the “Clear DTC” command is chosen from the menu, the check engine light
will turn off once the engine is started again. Our website has a list of
Chrysler DTC’s at:
