Has someone done a write up on what the parameter values are supposed to be. The reason asking is I just bought the dashdaq and was needing some values to go by. I done the search and didn't come up with what I was looking for.

THANKS
JASON

oil pressure 12 psi? seriously that sounds seemingly low. not that your wrong but out of curiousity where did you get this info Bismic?

Your question is very appropriate. The answer lies in how you want to set up your alarms. My oil pressure reference is based on oil pressure at idle (should have made that more clear). From the OBDII Theory and Operations manual:

The oil pressure switch activates at 5 psig. The minimum engine oil pressure specifications are 82.7 kPa (12 psi) at 700 rpm, 165.5 kPa (24 psi) at 1,200 rpm and 310.3 kPa (45 psi) at 1,800 rpm with the engine at operating temperature. Note - Oil pressure regulator opens at pressure of 75 psig to send flow back to the pump suction.

You will see much higher oil pressures when runnng (obviously), but the alarms should be set for idle conditions IMO. Probably the wisest thing to do is to watch what is typical, ensure that it is well within spec, and then set your own personal alarms so that you will be advised of any performance changes.

Other info:

Coolant:
Some say fan kicks on at 210 *F, some say 215, others say 220. Full explanation:

Engine temperature is not the only parameter that the PCM monitors to determine cooling fan operation. This is the reason that you will see some variation in engine temperature as it correlates to fan operation. The operation/description of the FSS (Fan Speed Sensor) from the PC/ED manual has a fairly good explanation as to how the system "thinks". This is not your traditional engine hits temp X and the fan clutch locks up. The fan speed sensor is a Hall-Effect sensor integral to the vistronic drive fan (VDF). The powertrain control module (PCM) will monitor the sensor input and control the VDF speed based upon engine coolant temperature (ECT), transmission fluid temperature (TFT) and intake air temperature (IAT) requirements. When an increase in fan speed for vehicle cooling is requested, the PCM will monitor the FSS signal and output the required pulse width modulated (PWM) signal to a fluid port valve within the VDF.

Engine begins to defuel at 221 deg. The thermostat begins to open at about 190*F to 195*F and is not fully open until about 215*F to 219*F.

Fuel Pressure:
Fuel pressure is regulated to 100 psig out of the HFCM. Then a recirculation regulator opens at 60 psig to take the fuel back to the HFCM. O-rings can start to fail over 75 psig. For 03's and 04's 50 is minimum. For 05-07 45 is minimum (no lower than 45: never-ever).

Transmission:
As for the "Factory" transmission temp gauge, it is a glorified "idiot" light as its response is severely dampened. The panel gage will show the temp as fully warmed up at 50 *F. Between 100-220F the needle will remain in the same position on the gauge. At 230F it will move up slightly to the middle of the normal range. At 250F it will move to Yellow. The gage moves to red at 280. This is supported on page 36 of the OBDII Theory and Operations manual. The tow/haul light will flash at 275.
Over 220 is too hot for continuous service. Never exceed 250 for more than 30 minutes. Normal tranny fluid is good to 300 or so, but be careful using this value. A measured temp of 250 actually means some areas and parts may be as high as 300 *F.

Oil Temp:
Should never exceed the coolant temp by more than 15 degrees (Ford TSB).

Coolant Pressure:
Well, look at the rating on the degass bottle cap.
