i dont think it senses exact temperature constantly. i only think it trips a signal when it gets to a certain temperature. kind of like a thermostat opening when it gets to 195.

 

What do you guys think about air/fuel ratio gauges?

 

[QUOTE=CSXfan;2124543]dodgeram07, how do you like your vac gauge?[QUOTE]

ya i like it... it helps out keep your foot out of the gas and help fine tune your best gas to rpm power range for mpgs

it helps with when i was having iac and plumen problems

 

With the gauge installed, make sure the oil is full, and drive the truck. Once everything warms up to operating temp, have a look at your gauge, that reading is going to be baseline. It will vary depending weather..... If it starts running hotter than you think it should, chances are, you are getting low on oil.

Oil cools by spending some time in the oil pan. The less oil you have, the less time it gets to spend in the pan, therefore, temps go up.

As for the 'best' place to install it? In the pan, at the lowest point would be my best guess, however, that could lead to problems all its own. (clearance issues with the pickup, leaking, etc.) If you had an external oil cooler.... somewhere in that plumbing would work pretty good... although, I note that our trucks didnt come with one, nor do I think it was an option. I am not aware of any adapters to install one..... best bet would be to look around the engine, and find a spot that sees good flow, but installing the sensor wouldn't cause more problems.

 

I think its glowshift who makes an adaptor that fits between the the oil filter mount and filter which makes mounting an oil temp or pressure guage easy. I think it has 2 or 3 ports. Will try and find it later today

 

Yep, here ya go.

Not sure which one you would need, but, that would be perfect.

 

I like mine, but keep in mind that the stock o2 sensors are not wideband, so you can not use an a/f gauge designed for wideband operations without getting a new o2 sensor put in the exhaust stream for that purpose. I guess you have to ask yourself what it is you want out of an a/f gauge to determine if you need to go wideband or not. If you just want to see if you are running rich or lean, and how well the PCM is working in closed loop versus open loop mode, then a regular a/f meter will work fine. That's what I use. If you are doing more detailed tuning, and want to know the exact a/f ratio, then a wideband is probably better suited for you. Do a search, you'll probably find my thread on my Split Second a/f meter.

 

I am just trying to decide what gauges to get I am going to get a trans and oil temp but need a useful third gauge and don't know what to get.

 

A clock?

 

I really like having an a/f gauge, that would get my vote. I also have a diff temp gauge on my rear diff, so that is another good option in my opinion.
