I am new to tuner cat, and like many others, I am going to learn by starting with the simple tunes first, then as I learn do more advanced things.

I'm having trouble with the fan temps thing. I can't seem to find the Fan thresholds. I read the sticky on ECM Constants, (found here) https://www.camaroz28.com/forums/sho...+reprogramming
I see the EGR enable controls on the list then the next entrys are: Fan Hysteresis and then Fan on/ oil temp high/low. Then Fan on A/C pressure. Am I missing something here?

 

It is deffinitly in the constants table. Go to table at the top, click on constants and it should be midway down. It shows fan 1 and fan 2 thresholds.

In the newer Tunercat software the fans on/off has been moved from the Constants to the normal Tables. Look about half way down the second column of Tables. It's something like "Fan Enable vs Coolant Temps.

 

On the new definition file it's "Fan Enable Coolant Temp vs. Speed", Under Tables, halfway down the 2nd column.

 

Thanks for the replys. I saw that table, but was confused because it was in mph. I have since found a post that explains that the mph is really the temps in celisus. Go figure. Anyway, thanks and i'm sure you will be hearing from me again.
