Torque Coolant Temp vs Gauge Temp
 

Coolant tank needed replacing so I order new and at the same time order Bluetooth ODBII transmitter

Changed out my tank(Oh what a #!@* joy) and went for a test drive last night. Got every thing nice and warmed up. So the Torque (Free version for now) Temp seem to match the Gauge during the warm up to operating temp.
As I drove, the gauge stayed in it's normal zone (a bit over 180) but the torque value climbed to 190s then to 201-202. I was just driving housing development streets with lots of stop signs. The torque temp fluctuated high 190s to 201, back and forth depending on stops.

Does that sound normal?
I have read that the ODBII value will be higher then gauge so I expected that
I haven't gotten out on highway yet to see where the torque values ranges at

I use the Dash Command app and my experience is similar. The app shows 180 at the 180 mark on the gauge. 200 seems to be at the hot edge of the "0" and that's where temps tend to get in low speed driving. The thing is, the fans aren't on yet, so there's very little air moving through the radiators. Once the fans turn on (210ish??), the temps cool off a bit and don't go any higher. If I'm worried about things, I'll turn on the AC so the fans cut on.

I did some testing with my durametric this past weekend to see if my oil temp gauge was reading correctly, and did some WP temp as well.

Gauge on the hash mark for 180, 82.5c - 180.5F
Gauge just past the hash mark (splitting the 8 fairly evenly), 86.3c - 187.3F
Needling splitting the space between the 8 and 0 - 91.5c - 196.7F
Left edge of needle even with the left edge of the 0 - 94.5c - 202.1F

This is using the "Engine temp" metric from Durametric, which I think is coolant temp.

I'm not sure how this compares with the readings from the ODBII port.

Seems to be the same for me with durametric.

For me, 200 was at the left edge of the 0. By hot edge do you mean the right edge of the 0? I never actually got any higher than the left edge of the 0 so I don't have any more data points....

durametric engine coolant
 

How get you get any coolant temps from your Durametric??
Just got mine and went through everything on the software??? What have I missed?
There is a learning curve with the Durametric..
Thanks

I think coolant is called "Engine temp", but not 100% sure as it has been a while. And I cleared my phone so I lost the photos related to my experiment above.
