Scanguage II question
Got my Scangauge II in the mail this afternoon, and hooked it up. Took a long time and some internet troubleshooting in order to get it to connect though.
Started messing around with loading some X-codes. I loaded the code for Oil Temp. Water temp seems to be already preloaded.
I've read several places on the internet that oil and coolant temp differences are a prime indicator of oil and EGR cooler health.
Idling in the driveway with the engine warmed up to operating temp. My Water Temp was 186F and Oil temp was 190F.
Are these good numbers to have??
What are some of the more important gauges to have loaded? I usally only use the truck as a daily driver/cruiser. I rairly tow heavy loads or take if off road yet.
Read this post: Write Up: Monitoring the 6.0L PSD.
As for the temps, from what I've read the best way to test is at 60-65 mph on a level freeway. Make sure everything is up to operating temperature and any more than a 15 degree differance between oil temp and water temp and you may be looking at doing some work in the near future.
I just bought a ScanguageII and so far have loaded the EOT, FICM voltage, FICM sync, FICM logic power, and ICP. I would start with those. The thread I posted above has a whole section on the ScanguageII.
This may be a dumb question, but I keep seeing reference to "ECT", which I am assuming is "Engine Coolant Temperature". Is it safe to say that the "WT" temperature I read on my Scangauge is the same as "ECT" or is this a different reading?
Below I have added to the list of Xgauges Fords specs for most of the gauges.
KO=KEY ON LI=LOW IDLE HI=HIGH IDLE OR=OPERATING RANGE (High idle for these tests is set at 2500 RPMs, and Engine at operating temps)
FICM Vehicle Power (Volts) (Should be 12 Volts, should not drop below 10.25 for more than 60 seconds, or 9.0 for 4 seconds. TSB 09-24-03)

KO=12.0 LI=13.5 HI=13.5 OR=10.5-15.5
FICM Main Power (Volts) (Should be 47-48) Your FMP should never dip below 45. If it does, your FICM is toast and needs repaired or replaced.

Here is another BAR if the above one is not working for you. The one below works for me.
Barometric Pressure (PSI)
KO=96.5 (14) LI=96.5 (14) HI=96.5 (14) OR=50 - 120 (7.3 - 17.4) kPa (PSI)

Manifold Absolute Pressure (PSI) (BOOST)
MAP is a standard gauge - but this XGauge is actually better than the standard one. It has a larger range which was needed because the standard gauge tops out around 37 psi absolute (about 22 lbs of boost), which diesels have no problem doing. This one should read well beyond 22lbs of boost.
With a little tweaking you can adjust this to read boost as you said.
To do this, just plug in the MAP code - get a reading from it with the key in the on position but the engine off, then based on the reading changed the last 4 digits of the MTH to whatever corresponds to your reading on this table
14.0 -- FF74
14.1 -- FF73
14.2 -- FF72
14.3 -- FF71
14.4 -- FF70
14.5 -- FF6F
14.6 -- FF6E
14.7 -- FF6D
14.8 -- FF6C
14.9 -- FF6B
15.0 -- FF6A
So, for example if you got a reading of 14.5 PSI with key on engine off you'd change the MTH to 01220320FF6F and the reading should read 0.0 with key on engine off and would then show how many lbs of boost you were at when the vehicle is running.
