Cylinder Head Temp Sensor
Temp sensor on the front driver side head, is there any negative to moving it to the rear passenger side head?
Other than a steam pocket, I can't think of much that would make it a bad idea.
Thoughts?

Yeah.. you can move it. Keep it any where ON the heads. It may be a few degrees different, but it is for your gauge. I do not see a problem and have considered it also. But I would like you, keep it on the sides of the head(s) and not on the ends.

You should be fine. As I built the harness for my 24x, I'm moved a bunch of stuff around in the harness and I contemplated doing exactly that. It would have made wire routing a little easier, but I ended up leaving it where it was.
Moving it farther back like that will just put it a little farther upstream in the coolant flow by, what...maybe 8"...? Not a big deal, in my opinion...

Yea gonna start building a second harness for the car actually and rather than just repin the ends, its gonna be stripped to plug and wires so I can lay it out how I want stuff to be. That single wire for that sensor is a little to fragile to be hanging out by the turbo so I want it farther back.

just jamming the sensor anywhere that's aluminum is probably close enough, it's not a very accurate temp gauge to begin with
hell you could just stick it in a line T in your heater hose and the gauge would read differently, but probably still be a good enough reference
if i were a real picky bastard, i'd rig up a potentiometer, get avg. head temperature with an infared heat gun or something, and tweak it till the gauge was fairly accurate regardless of its location

Ive read that you should stick it in your waterpump on the other side of the pcm temp sensor. Might as well see what temp the computers reading but on your gauge. Im pretty sure if you put it on the other side your temp gauge will read more or vise vers due to coolant flow.

Like all GM temp gauges, they want the dash to give the driver a margin of safety before the engine temps really hit there. So, seeing a higher number isn't that bad, I would be monitoring the actual PCM temp anyways.

How big of a margin? not trying to hijack but my car never gets past the first white line on my temp gauge, no wonder i never get closed loop.

My temp gauge and PCM readings usually are very close, if not the same (as much as you can tell with an analog dash gauge).

Granted I am basing it off my truck which has the ECT and gauge temp usually off by ~20 degrees.

that's the way mine is set up. PO set it up like that, and i really don't see why i should move it....and when i had datamaster on the computer, running at idle, it was very close to what the gauge was showing. the gauge would just move a little slower then the temp from datamaster was showing...
