Utilizing Scanguage Readings

My observations ...

WT (Water Temperature)

According to the Scangauge users manual:

Quote:

A vehicle with a 50/50 mix of coolant and water will not boil over until about 265F (129C) at sea level. This will be reduced at higher elevations.

When highway cruising my MCS runs 195F - 200F (90C - 93C). In stop and go traffic it runs over 200F. The radiator fan will come once it exceeds 220F (104C).

IAT (Intake Air Temperature)

When highway cruising my MCS runs less than 10F (-12C) over ambient ... 3F (-16) over being the lowest I've seen.

MAP (Manifold Air Pressure)

I've programmed an XGauge to show actual Boost but don't pay much attention to it as you need to be at WOT and have someone else read it.

VLT (Battery Voltage)

According to the Scangauge users manual:

Quote:

Normal running battery voltage is between 13 and 15. When the engine is off it should be between 11 and 13. Voltages higher than 15 volts can damage batteries and electrical components. Voltages below 13 when the vehicle is running could indicate poor charging of the battery. Voltage below 11 when the engine is off could indicate a low battery charge or a shorted battery cell.

My battery registers 13.6 - 14.0 volts when on depending how many accessories (lights, A/C) are in use and about 12 volts when off.
