Gauge accuracy
 

Just curious if it is better to get mechanical gauges or if the electronic ones such as some
tuners provide are just as good/accurate? I am looking to start bombin my truck and know first thing is gauges and was thinking if I get a tuner that has gauge functions it would kill
two bird with one stone. Thanks for any insight or opinions.

they say mechanical is better. but me and my buddy are both on are 2 set of egt gauge. he had auto-meter and i had glow shifter. i think you would be find with buying the combo set up with your tuner. just don't buy and edge. go with bully dog or smarty

Whats the problems with the Edge? I was looking in to the Edge CS or CTS with attitude or the PPE Xcelerator but notice it has no gauge functions. I also looked at the Smartys but got a little confused because it said you have to download so does it not come with tunes allready or do you just get the "tool" that you download tunes from their site into and transfer to the truck?

That electric versa mechanic accurracy is a myth.
Even simple electric gauges are working with an accuracy of 1.5 % on the scale end value. Do you think planes do use mechanical gauges?:nope:

the edge just don't fell like it gives you the power for some reson

Sorry I think I mislead the direction of the question, I was wondering with the electric gauges using factory sensors and not getting the most accurate signal from them for example I have read the tranny temps read 10 to 20 dgrs higher because the sensor sits higher in the pan (tuner gauge signal) compared to a sensor that is installed in the pan down low in the atf. I guess I could just be over thinking this :w2:

That's not a gauge or a sensor problem, that's a "temperatures in the transmission actually vary that much" problem.

It depends on the gauge... When it comes to temperatures, EGT's especially,, there's no such thing as a mechanical gauge, unless you're talking a periscope to see what color your exhaust manifold is. For pressures, mechanical gauges are accurate enough for the most part, cheaper and will never suffer from electrical problems.

make sure sender and guage are made from the same manufacturer. As an example VDO and motometer don't match- resistance curves are different and the shown values differ too.
Sensor location is extreme important. I avoid in the pan mounted sensors because the pan itself acts like a cooling aid. As a result of that it gives you the "lowest" excisting temperature.

No- I personally think temperatures are the best indicator for failure. I would love to have independent cylinder exhaust temperature control, enableing you to see directly which cylinder has difficulties or a bad combustion.
But Beru already develops such a glow plug being able to act as a glow plug and also able to read MEP.
This needed to keep emissions stable even after 100kmiles of use.
