V-Series Cadillac(s)?
2013 V wagon stealth blue (sold, so sad); 2022 CT5 Blackwing
on all of my previous GM performance cars (corvette c6 z06, second gen CTS-V), the engine temp shot up while running at idle or slow traffic to well over 200 because the radiator fans arent programmed to come on until the temp gets higher. with the CT5 blackwing, the engine temp seems to remain around 195 all the time - not sure if that is because the fans come in earlier, or if perhaps the digital display is not accurate (the dash gauge on the second gen CTS-V is certainly not) or some other reason - it would be fun to connect the car to something like hp tuners to get a read on what is going on, but i dont think that product supports this car yet....
 
You should still be able to scan the car with HP tuners to see what it is doing, but wont be able to do any modifications to anything.
 
i have their scan tool- i'll give it a try
