So the water temp guage in the 987 obviously doesn't show the true temp. Mine stays at a constant 80 degrees through track days, city traffic, and highway cruising.
I've heard you can access the true temp through the
OBD
, and I'm wondering if theres any way to hardwire this to the dash temp gauge or if an aftermarket gauge is the only option.
With the
PIWIS
I can change the temp read out for a
981
. Not sure about 987.
It appears I have posted this in the wrong category. If any moderators seeing this could move it that would be great.
Indeed you did... moving in 5, 4, 3, 2, 1....
And here is your answer...

Not having to DIY makes it worth every penny, and it's a clever device, using an Arduino and WiFi and CanBus and programming... to give you accurate readings (at least as accurate as the ECU receives, plus your oil temp, oil pressure, and system voltage).

I have the vent mounted one (it was designed with my feedback on prototypes..) and I refer to it ALL the time. Highly recommended.. (you'll probably be surprised at how much the dash water temp gauge is joking with you..)
The quick answer - on the 987 - no one has reported finding a way to make the factory gauge accurate,
PIWIS
or not.
The Sport/Chrono gauge is the answer (even if you don't have sport/chrono..)
I had a
987.1
and .1 and neither ever were stuck at 80* even on the street. Do you mean 180? I think something is wrong w/ yours.
Take a look at the flag by the OP name. 80C is 176F.
If you are driving normally and the car is not overheating don’t let the actual temp bother you…. after months of monitoring mine I noted the usual water temp but that did nothing for the monitoring of the car or my driving, Any plugin
OBd
monitor would help if you still want to check it.
The problem with the stock gauge is - it won't tell you you're overheating until you HAVE overheated, and then it's too late to do something to avoid that happening. Having a real time accurate readout and a functioning brain might help avoid the overheat (which will undoubtedly happen in the worst place at the worst time, and cost a LOT of money somehow.. BTDT).
Knowing where the engine normally runs under various conditions might just help the driver determine something isn't right before it becomes a disaster (ie - overheating).. kinda goes double for track days..
Don, I am not sure what I've done to get on your wrong side. Your last few posts quoting or responding to mine have been to contradict me.....
I value your role at Planet 9 and appreciate your time - however, I would seek your understanding that both sides may be correct depending on perspective.
Now to the problem at hand... the problem with temps is that if something is wrong - it goes wrong really fast. There is not much time to react or take action.
All I am saying is that with normal driving a minor temp fluctuation is not going to show any real actionable information - since I was actually one of those people who had an
OBD
reader set at the temp. This was true even during track days where the temp only flucuated a few degrees (brakes and
tires
are a much bigger problem).
Now, if someone still wants to monitor - have fun shopping for a monitor - not saying there is anything wrong with it. just consider that it may not actually be as useful.
That being said, I am glad that in the
718
, they did add some additional information as stock + some related info like pressures, both oil and water temp - but yeah still same issue - when something does happen time to react is really short.
Sorry - I didn't mean for it to sound that way.
Please remember, I've been driving for longer than most people on P9 have been alive... so I go back to cars like my avatar - '65 Jag XKE. It was notorious for having an inadequate cooling system.
Apparently, when it was designed temps in the UK rarely went above mid 70F's... not so much even in NJ. It was thought that a fairly low speed single blade 1" wide electric fan would be adequate to keep the engine from overheating. That thought was mistaken, and finally about 5 years later they added more blades to the fan, and eventually replaced the one big fan with several smaller high-speed fans.
I can rather vividly recall driving in traffic where the coolant temperature gauge started climbing - yes - rather fast but not instantly - and I had to pull off the road and let things cool down. My wife was not amused. If the Jag hadn't had the coolant temp gauge I would have been facing real overheating with the steam and all that good stuff, and then the wife would have been mightily displeased. I eventually added a manual fan switch (parallel to the coolant tank thermo switch) and when I saw the needle on that gauge start to move, I'd immediately turn on the fan. That often helped. If that wasn't enough I'd turn the heater on full-blast. Wife was displeased with that solution.
A
987.2
Porsche
- if anything - seems to have an overcapacity cooling system, since on cool days the fans never run, even if stuck in traffic. I do watch my water/oil temps - mostly to know when they're warm enough that I don't feel guilty holding it in one gear going up to 6,000 RPM... but I do see normal operating temps according to the factory coolant gauge that are really from about 155F-209F and the needle on the dash never moves. What's interesting is how closely the oil/water temps coincide, but that's due to the water/oil oil-cooler on the engine...
Anyway - my water (and oil) temps are always displayed right on the left side of my dash, and I like having them. Sort of a pacifier for me when I don't hear the fans running in conditions where I'd expect them to. This is available to purchase, and on the
987.2
cars displays oil and water temps, oil pressure, and volts.
