I want to install a Water Temp Direct reading Gauge
I know I can put a nipple and a T where the water temp sensor is on top of Intake but is there another place? if not will will it show a good temp plugged into a T because of no water flow?
I love my 350 BUT the 6.0 can be a real pain when you do something it does not like.
If you remove the OEM one the PCM will have a fit.
Why not get something like the OBD2 blue tooth reader and
use a smart phone or tablet? You could also get a Scanguage 2
and read it that way. If you don't want it hanging out you could
always plug it in when you want the data. Plus with the two methods
I just listed you have a way to read live data and don't have to
mess around making something work and get along with the OEM hardware.
^^^^^^ X2 what Sean said -- there are a ton of other important stuff to watch that is "hidden" from you but is circulating on your trucks data network!
The reference values in the PC-ED manual are calibrated based on the location and accuracy of the sending unit. The absolute temperature doesn't matter as much as it's relation to the other PID readings, inside the operating range and tolerances of a correctly functioning sending unit. You can verify if accuracy is sufficiently correct by comparing ECT, EOT, and TFT to ambient temps after not running the engine for more than 8 hours to check for bias in the sending unit, or you can swap the ECT and EOT sending units to see if the readings change drastically.
In the price range of these sending units I cant image we're better than +/-3% accuracy, if you're within +/-4*F that's probably as good as it's going to get. Autometer SSE gauges are something like +/-5%, their high end racing stuff is +/-1%.
If you stack in another sending unit, you could conceivably have a 6%/11*F difference even if both sending units are reading within an acceptable accuracy range.
It might be cool if someone got a board and put together something that could tap the OEM sending unit signals to the PCM and essentially fake a sending unit reading in the range that an aftermarket stepper guage would want to see, and send that signal to a gauge face, that way you could see the correct reading but on a "real" gauge. Like how an Isspro EV2 HPOP gauge tap into the ICP connector. But that would be "cool", not necessarily "practical". An OBDII gauge is practical.
