[MINIAC]

Now that I've fitted a Scangauge, I'd like to know how to make the best use of the gauge readings to determine whether there is a problem.

VLT (Battery Voltage)

The User Manual is pretty clear on this one:

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.

WT (Water Temperature)

Again from the Users Manual:

Quote:

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

What coolant temp should you see cruising at highway speeds?

MAP (Manifold Absolute Pressure)

I know the reading has to be adjusted by subtracting air pressure relative to altitude to determine boost. Do you correlate this reading to TPS (Throttle Position Setting) or LOD (Engine Load) or some other reading to determine if you have a boost leak?

IGN (Ignition Timing)

Anything to watch for here?
