You know, after I posted my first response, I got to thinking about it and then saw your post.
I think you are correct based on what I've read. Once warmed up, regardless of OAT, a rig in good shape should be running in a standard temp range. Too little cooling is just as bad as too much cooling so regardless if it is 10F outside or 100F outside, you want the Cruiser running in the prime temp range which seem to be in the 195F range give or take...Can't remember the exact temp at which a stock thermostat is designed to be fully open but I guess that is close to the prime WT you are after. Neither too hot nor too cold, just right
The stock thermostat on the cruiser has 180F (82C) opening temperature. According to Raventai's post in one of the cooling threads, it should fully open by 203F (95C). From all the data posted, it looks like the normal operating temperature is within 190F-200F range, on flats at least.
Interestingly, my 2006 Sienna, which has the same thermostat specs as the cruiser, has a 182F-186F operating temperature - probably because the cooling system is still brand spanking new?

I think this is what a brand new cooling sytem in a 80 will run also. That is about what i am getting after going thru my cooling system with the modded fan clutch.
Even on the mountain pass here on I-40 in ABQ, in 3rd, pushing 75mph, I've never gotten over 202 degree F. And when it leveled out, the temps went back down to about 190 degrees (that's with an IAT of around 100-130 degrees).
I am going to wheel with the Scangauge connected on the 30th of September. I will report back results then.
Oh, and I am overly anal about my cooling system--full flush using Toyota red every year, along with new fan clutch (not modded), new thermo every year, and OEM radiator.

I gave in...it's on the way.

Hate that mud...
Got my ScanGauge II with new "XGAUGE" firmware earlier this week. Ron Delong and the others at Linear-Logic have sure come up with a slick product. It's dead simple to hook up and most of the menus are very intuitive. The pre-programmed real-time gauges work great and provide readouts of all of the standard OBD-II sensors. I did RavenTai's temperature gauge mod a few weeks back, but ever since then my temp gauge rarely makes it to the mid-point position. So I had been wondering if either my gauge wasn't reading right or I had somehow screwed up doing the mod. The ScanGauge confirmed that my coolant temps are on the cool side (179-181 normally, except on long hill climbs or in very slow city traffic), and more or less match RavenTai's published post-mod numbers.
I was looking forward to also being able to monitor transmission fluid temperature, but as of today you can't do that on a Land Cruiser. The new ScanGauge firmware (version 3.14) allows you to program in additional user-defined gauges. Linear-Logic calls this feature "XGAUGE". Basically you program in 5 parameters using hexadecmial codes. One of the codes is a command that the ScanGauge sends to the ECU, 3 others are parameters that tell the ScanGauge how to interpret the response that comes back from the ECU, and the last parameter is the name you want assigned to your gauge. The command code used to determine ATF temp is vehicle manufacturer dependent. Linear-Logic plans to publish all the parameters you need for your vehicle, but they haven't figured out LC's yet. You can check out the vehicles they do have parameters for here: http://www.scanguage.com/support/pdfs/XGAUGE.pdf
I've played around some with the OBD-II interface on my '97, using a Python program on my Mac and an OBD Diagnostics "All-In-One Scan Tool." So I thought maybe I could figure out the command needed to return ATF temp from the ECU. However, despite a fair amount of searching on the web, I couldn't find the vendor specific sensor code that is needed to do this. I'm 99% certain it's possible, since the tranny temp sensor interfaces directly to the main ECU and the ECU controls the overtemp light in the instrument cluster, so obviously the ECU is monitoring the ATF temperature. But without knowing the sensor code it's not easy. Joey at Linear-Logic says they are committed to publishing the parameters necessary for a user to add a ATF temp gauge for Toyotas, but they don't have it yet. If this feature is one of the main reasons you are considering a ScanGauge II, you might want to hold off until you see "Land Cruiser" (or at least "Toyota") listed on XGAUGE web page I quoted above.
BTW, Linear-Logic offers a group buy discount for IH8MUD groupies; $149.95, including shipping. Call them and ask for Joey.

does anyone has scanguage with Super Charger? I want to see some numbers. Thank you
Hi guys,
What's your idling charging voltage? Mine varies quite a bit...14.5V during start-ups, around 13.5 during stop & go traffic. The lowest was 12.5V in gear at stoplights
I expect normal charging voltage to be from 13.5V-14.5V but interested in what others are.
Please post yours!
P.S: The truck has 114K miles with original alternator. I did have a completely discharged battery (key in ignition "On" position for days - my bad) before collecting those data so I'm not totally sure it mattered or not.

Does the Scangauge II display the readiness monitors and tell you which ones are/are not set?

Group Buy Is Dead
I tried to order this last weekend and the group buy function has been removed. You can still order one through the site but it is $159.99.

I'm interested in buying one as well, anything new on this topic?
also, I don't see an add to scan gage's support page concerning Toyota yet. Unless you count the Prius.

12.5 is to low if your battery is good. Was it at night with lights on? I have not seen below 13.1Hi guys,

Has anyone been able to improve gas mileage with their 80 using the scangauge by adjusting the "nut" behind the wheel? ;p
See review here:
http://www.andybrain.com/archive/scangauge-review.htm
He's basically saying that he's able to drive more conservatively by adjusting the amount of lead in his foot according to what the Scangauge mpg readout is in his Saturn.
Granted, I used to have a Saturn SC2 and I could drive it like I stole it or like my great grandmother and I'd still get great gas mileage, just that the range was larger than with the 80.

flem- trying that on my 80 now and will let you know if it makes a difference. It is surprising how good the instantaneous fuel economy is on a flat road around 40-65mph (reads 16-22+mpg), but even a slight incline and it all goes to hell.
As for coolant temps, at around 60-70F ambient, I am seeing a range of 184-190F with IA around 100F- this is with a landtank-modded fan clutch.

This is the coolest thing ever. I decided to order one after reading this thread and just got it today. Haven't hooked it up my LC80 at home yet, but I did hook it up to my work rig, an '05 Blazer and it rocks!
Looks to be very well made and software is very well thought out and extremely easy to use. Who designed this thing and the software deserves some serious kudos.
I can't wait to set it up in my Land Cruiser!
Heck, it's even made in the USA, which is a HUGE plus.
