Is like the HVAC to come on 100% when the truck is remote started. Is there a setting I'm missing? Is there a known Forscan mod? It's well over 100 today, and I'm really wishing this was a thing...

Make sure the remote start climate setting is 'auto' and it will max out if required. When you then go to key-on it will revert to last setting.

I've never seen it actually go to full "max AC" style cooling. It will cool, but not Max AC.

Mine goes max Ac. I don't know
Define "Max A/C", because full blower alone is not MAX AC. MAX AC should be full blower, low temp, and also circulation ON, and my super duper automatic climate control never, ever, turns circulation ON, which of course helps cooling the vehicle. If I turn it ON manually it goes out of AUTO.

Agreed about circulation. However, when I remote start the truck and its blazing hot outside max Ac button illuminates as well as the circulation button.

I thought when remote started it went to a default temperature of 70 something maybe? or possibly that was for a heat setting.

But regardless, mines just an xlt but when remote started it does turn the a/c on and it's cooler and like someone said when you do turn it on fully it goes to the last setting.

If I remote start mine sitting outside right now, both fans go into high and it sounds like a jet ready to take off (they slow down after hitting the start button, it's VERY rare to hear both engine fans on max). Remote start climate always defaults to max AC (recirc on = "max AC") when cooling, however its set point is based upon the 3 settings which really don't matter (think the range is 68-72 degrees) when it's 100+ in the truck. I wish they put the rear window as an option to crack and just blow out the hot air initially, you know making use of ALL of the electronics and sensors onboard.

Even the 'auto' mode when key in run, at set point 1, will go into full max AC when the temp delta is high.

I see the exact opposite. When I get in my truck with a remote start, the fans are on medium and recirc is off (except I have mine hardwired to on... but the is beside the point). As soon as I crank it and hit the "max ac" button I can hear the fans more than double in speed. I guess I should go double check and make sure an OTA didn't mess with my settings.

Hrm, that's odd. Both of my fords have the same logic in them w/ remote start and HVAC controls. I've done nothing to their settings. Is there forscan changes to alter the behavior of remote start climate?

that was the question the OP asked.
Is your PB and MME behave the same? What is this hardwire recirc you speak of? Is it something the truck can see and may it be tripping something up?

Can confirm mine does full max AC on remote start too when set on auto in dash settings. Check settings and if you still can't get it going post your asbuilt because your truck is weird. :)

Not sure how to post an As-Built, but here is the VIN:
