ECU reporting wrong temp, No closed loop

[luigi daniel]

what matters is the volts across the sensor at 180F its 180F true water temp(thermstat marked 180F) and IR pyro gun shows it there
the voltage is 0.65vdc at 180F.
if the voltage is correct, and the scan tool shows, way off, the scan tools is "wrong"
the scan tool and plug-ins must match the car, engine,market codes, , VIN and ECT type (of which are 5 at least) " i think the tool attempts Vin lookups? "

your ECU reports Volts, not temp. so the tool must not lie. (it must know your MARKET CODE or fail (in the VIN it is)
i upgraded my table to show more data points. and added volts for OBD1 owners.

"scanner same as initial" ECT, ?how is to say? the first ect is USA ect or the second/?. nor if tool even works ?
this ECU only works with 13650-57F00 ECT, no others.

I have placed the order for TX40T sensor, on Rock.
First ECT referred to is US, second is Hella.
I know for sure that the scanners with the GM cartridge are offering the car selection by VIN, as alternative to make/year/model path that I've used before - never tried vehicle selection by VIN...........
Anxious to get back home to progress the tests based on the above recommendations !
Thank you again !
