Aftermarket gauge selection
Posted 05 September 2005 - 10:26 AM
So, given that nowadays the ECU measures a lot of stuff and an OBDII reader may be enough, I wonder what gauges you guys feel would be helpful to monitor in the long run?

I think the most under used gauge is the one we all have, the air gauge for the tires. Proper air pressue will increase gas mileage.
HAH! you're right of course. I usually overfill my tires knowing that they may well be underinflated when I remember to next check them.
thanx for hijacking my thread btw ;^)

How about a fuel guage? I mean one that works properly (Yeah, I drive a '95 Legacy and it has never told me the truth!)
Seriously, Texan, you pose an excellent question. Even if the ECU is controlling everything I, as a human being (nominally), want to be informed of operating status as much as possible. "Early warning" is invaluable.
Oil Pressure would be nice, I really miss that. Oil Temp too.
An Ammeter. Maybe even a Volt Meter.
How about a Vacuum Pressure guage? Never had one but I think it's something I'd like to watch. (Or is it even necessary on a "modern" engine?)
Am anxious to know what others think. This should be a great thread.

Then an oil pressure gauge. Got one of those also. Mechanical.
With the price of fuel rocketing up, a vaccum gauge would help in being less lead footed and is also a very usefull indicator of all sorts of possible problems (vac leaks; faulty valves, rings; clogged cat, etc.) I will probably install one of those in the not so distant future.
Finaly maybe a fuel pressure gauge. Maybe not a complicated cockpit one with separator etc, but a simple mechanical one spliced directly into a fuel line. I got a VDO miniature gauge that's installed just like that. Not expensive. Engine stops: open the hood and you can immediately know if it's a fuel prob or someting else.
My two cents.

Let us know how the installation goes.

Today has been a chainsaw day to get rid of a dead tree, I hope to look at the Subie tomorrow afternoon.

Another thing I've always felt was odd is when folks want to measure something but then have now way to make a change or do nothing with the information. I suppose I can see where a boost gauge or a vacuum gauge would be useful for controlling the lead foot. And might also point out probelms developing - what? I dunno. And is there really any useful reaction to - say - oil temp?(is it just a redundant coolant temp indicator?)
this could be an educational thread for me - keep 'em coming!
