On my 02 SS I put in a Hypertech 160 thermostat and reprogramed with Hypertech. The temp gauge still runs one pointer width below 210. What gives? 45 degrees today.

Maybe the guage uses a false sending unit,like a light would use.

Ford used them with their gauge clusters. The sending unit has a set resistance so when the the engine is cold the gauge reads cold and as soon as the engine warms up ,the resistance value of the sender goes to a set resistance.Kinda works like if the vehicle has an ediot light for the temp light. The sender is more like an on/off switch than a variable resistor.

This is not a FORD!!!
If you have reset the "Fan ON" temp with the Hypertech to ~160 you should not be reading much higher than that. Only thing I can think of is that the Hypertech III does not have a very good reputation, they've had to release an update to the software. Most recomend using LS1 Edit.

Are you sure both fans are coming on? I know Elie had to have one fan replaced as it stopped completely. I have had one fan replaced because it was getting lazy. I caught that one before any serious cooling problems developed.

Thank You for the help. I'll hook the HyperTech back up and be sure I have the "Fan On " set properly. I will also check on a software update.

I've found the temp gauge to be very inaccurate. I checked a car last week that read a hair under 210 on the gauge but the reading that I scanned was 187. This is with a 180 thermo.
