For example, the stock temp gauge means nothing. We might as well have an idiot light. I found that the "normal" reading, meaning the place the needle sits about 99.9% of the time, could mean that the engine is anywhere from about 160 degrees, to over 220 degrees. Watching the temp monitor on the Evo, and comparing it to the gauge, when the Evo hit 160 the gauge was at its normal operating temp location. On my way back from Phoenix, pulling some hills with an outside temp of 113*, the gauge on the Evo got as high as 218, and the needle on the stock gauge never moved! For anyone that is wondering, normal operating temps for a 5.4 are in the 196-204 range, depending on outside temps.

It has been very enlightening watching the monitors on the Evo. Anyone who really wants to know what their engine is doing should get the Evo just for the monitoring functions.

 

The stock temperature gauge "is" practically an idiot light...Works on the same principal as one..

 

DITTO, on the oil presure gauge also! All that is needed for your factory gauge to read normal is "about six to eight psi

My auto meter gauge readings are 30 psi "at idle", 50 psi "normal speed", and 75 psi "cold engine" this is on 5-30 mobile 1 oil.
I found this out by troube-shooting a intermittant oil presure light, I remove the oil sender from my engine and hooked it to a regulated air line and ran the pressure's up and down to test it, and watched the instrument panel gauge sit in the middle of it's range and not move till the pressure was almost to zero. I sub'd a 10 ohm resistor for the oil sender " to keep the PCM happy" and now rely on my auto meter oil pessure gauge.

Sounds like you're talking about a woman!

 

It would be nice if they could add a feature that you could moniter(sp) the oil pressure with the edge. I would like that instead of being able to moniter the Mass Air Flow Temp or something like that. It still has alot of great features that I love but it really would be nice to have a Oil Pressure moniter(sp) feature.

Your all correct. The so called gages are not functional beyond a go/no-go indication.
There is no sensor on the engine or any way in the PCM to get a varying oil pressure reading. Put a real gage in place.

 

glad to know i wasnt the only one staring intently into the green glow lo

 

My main justification , oops, reason for buying, the Edge was for monitoring and I really enjoy checking the stuff out. Engine temp is one I keep an eye on, especially in the Texas heat. Mine stays between 194 and 196, has never exceeded 196.

 

Mine likes to go to 210*

 

Hi Chester.

That's right where you wanna be

 

Finally! Something right.... It stays around 208-210 all the time.
