Installed my new 4" MBRP turbo back on my 2005 6.0 and also bought new Scan Gauge II and was wondering what gauges to mainly monitor. I was thinking about the engine oil temp, coolant temp, tranny temp, and boost. Any suggestions?? I would rather not keep changing all the time and look at the best and most important ones monitor. There are so many I am not sure what is best. I have no other sensors like fuel pressure or EGT. Thank you for any sugesstions.

 

boost you get from the PCM isn't a true value. it's a calculated value. I'd get a real gauge for that

I suggest you do ECT, EOT, FICM Volts, Batt Volts as main gauges. keep Trans Temp as a quick hotswap for when towing

 

How much over 12V should I consider normal? At what point is it time to worry. I was getting 12.4 with the engine running. I was thinking it should be higher with the Alt. feeding the batteries.

 

Here are the Xgauges I now have entered in my Scangauge II. The ScII reads x gauges from #24 to #0 So I entered them alphabetically by name for easy access. I normally run:

FMP, ECT,EOT, VOLTS. While towing I will switch to add Fan speed and TFT.

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

Thank you for all your great information especially the Boost table and how to properly set it up. I will go out and do it now to have it working correctly. I understand the EOT and ECT should not exceed 12 degrees apart correct? What temp is normal for the EOT?

 

My 03 show 13.8 volts idling

 

Its 15* apart for ECT vs EOT to be in Ford Spec

these 2 gauges should also be 1-2* apart after a cold soak at startup

Also may want to watch FICM and volts at startup
