2008 6.4 engine/tranny temp gauges
Doesn't seem normal to me but I have watched for a time now and engine gauge( first one after the boost) will take 8 to 10 driving miles before it will start to move,where as the tranny gauge will start to move if you let it set and idle after cold start up and be normal after 3 or 4 miles. It is blowing warm air from the heater to when it shows cold on the engine temp. My 2000 7.3 that I installed the Isspro gauges in was exactly the other way around. Anyone else out there have any infomation on how there gauges act. Ask the service department if they could be hooked backwards and they said no because it was a harness assembly.

The engine gauge gets to the warmed up position when the engine is about 180-190F. The trans gets to the warmed up position when the trans is at 50F. It isn't possible that they are connected wrong - it's the way the gauges work.
If you want REAL data get real gauges. Those gauges are for people that always want to see that everything is fine.

Thanks Mark that makes sense, if the tranny warms at 50 degrees. Know what you mean about gauges, thats why I put the Isspro in the 2000. Been looking and waiting for DieselManor or some one to have the instructions/mounts like the one in my 2000, My 2008 has a grab bar on the pillar so not sure about mount and connection places for pryrometer probe and tranny connections.

The gauges are not actually wired to the engine sensors. The sensors are wired to the PCM and the information to the dash instrument cluster is all digital data sent via the vehicle's network from the computer to the instrument panel. If you hook up a scan tool the data is accurate but what the instrument panel shows doesn't always match.
Example, on my 04 and 06 the MPH were high by about 2 mph per the dash when compared to GPS; however, the MPH was right on when comparing the digital data on a scan tool or scan tool software on a laptop. Haven't checked the 08 yet.
I could watch coolant temperature rising on the scan tool yet the dash wouldn't move at all. Reduces warranty ticket complaints....
BTW, your oil pressure is just a switch activated reading, no analog value. Switch detects set pressure and gauge goes to fixed position (via network data). No warranty tickets for low oil pressure complaints.
FORD, give us accurate instruments with real engineering units

The only trucks left that I know of with "real" guages are GMs. My dad's envoy SUV, you can sit there and watch the engine temp guage rise, and heat coming out of the vents goes along perfectly with what the guage reads, step on the gas and get the revs up, oil pressure goes up, turn on the headlights, voltage guage goes down for a split second then comes back up as alternator picks up the slack.

As far as the "trucks" go, yeah, the gauge IS a gauge.
Reps to bnmccoy for being right on track...except for the "give us real gauges" part. As far as my warranty work goes, keep the glorified idiot lights.
