Thermostat Question
Thermostat Question I puit the hypertech 160 in my car and it was already tunned for the fans to come on quicker. My question is I never saw a change in the temprature gauge. Is their anything else I need to do or is this normal?
What year is your car?
Later years were not correct. Basicly a dummy gauge. Do not recall effected years. I am sure someone will add to this. I think it was anything from 00-02???
I know 98s read correct.

99+ F-Body's use dummy gauges.... 98s are the only year that use "real" temp gauges (98 cars had a direct temp feed to the gauge cluster... 99+ rely on the PCM .. )
Basically... most people are morons.... if it was 50* on 1 day and 0* the next.... and the temp gauge wasn't the same... they'd go in and complain the car wasn't running right... (most people don't understand how cars work... as such car companies need to dumb the gauges down)
to fix this.... GM made the gauges dummy gauges .... basically three levels.. warming up (left to middle) ... operating temp (anywhere around middle) ... too hot (right of middle)
You need a scanner to see what the cars actually operating at

^^^ yup, as mentioned, even though there is a slight change in the position of the needle, it's not reading accurate (on 98s , you can see fluctuations in temperature by looking at the needle, whereas 99+ don't fluctuate anywhere near as much)
98 cars had a feed that came right from the sensor to the gauge cluster (3 prong temp sensor) , 99+ go to the PCM only, and then are fed via the serial data stream to the gauge cluster... this data seems to be dummied down.
GM (actually alot of auto manufacturers) do this because when you put a real gauge in, people get paranoid... They see the gauge fluctuate between when they're curising down the highway and then they get stuck in traffic and it gets hot... most don't understand this is normal (no air moving over radiator) so they bring it back complaining it's "Over-Heating"
