    Fans Setting? Fan comes on high on cold start?

    Guys,

    Just recently picked up a MPVI2 for data logging and thought it would be useful to have. In others words, I don't know sh** about them! LOL

    Anyway - recently noticed my fans come on high during a cold start up. Even like a day today, 25degress here this morning.. start the car. Fan comes on high almost immediately. We're thinking it's more than likely a bad thermostat but I wanted to see if anyone here could take a glance for me and validate that my fans are indeed not supposed to come on that early. And.. teach me what you're looking at!

    Change fan setting axis (right click, label) change this to 170 and make the first column 0, then interpolate the data...

    Being 50 at 192 makes it run when you start the engine, been like this from the gen 4 days

    Ben Charles.. thank you sir for taking the time to help me out. Please don't beat me up too much, I tried to preface the post by letting everyone know I'm a noob! LOL

    Is this correct or am I way off?

    Make the entire first row (ECT side) 0... then depending on thermostat temp I would have say 200 ECT at 90 and and smooth between 17x and roughly 200, past 200 have fan at full speed.

    I seen you post on corvetteforum.. I’m T/A KID on car forums

    How's this? If I'm still way off.. I just emailed my tune to you. If you don't mind.. can you make the settings like you would prefer to see and use the snipping tool to send back?

    I fixed my 2014 GMC Sierra by just disabling the ETC code in the Engine Diag,
    I don't remember the ETC code, you can scan your ECM and usually you will find it in history status.

    If your defroster is on your fan will come on.
