I switched tunes this morning. I was playing with idle fuel. I tried to start it and it won't start. I get this message:

You have a settings error ! on MyCar
This means there are conflicting settings and the megasquirt does not know how to handle them
The following error was reported by the Megasquirt:
Conflict on programmable on/off outputs pin
-pin already in use by-A/C idle up out.

When I disconnect from Tuner Studio the car will start. Just an experimental tune. It won't let me load any tune until I take care of this error When I look into programmable outputs it is not enabled. I'm too noob to know what it should be set on if at all. Thanks in advance.

 

Let us know what Megasquirt you have, and attach your tune.

Find "Feature List Showing IO Pins" under Basic/Load Settings, and see if there's any duplicates.

 

I have MS3 by Revereant. Ver.1.4 These are the two tunes I was messing with. Not sure what the car is actually running on now.

 

Are you having problems with both those tunes? Do you have an older tune saved you can go back to and see if it works?

Maybe temporarily turn off AC Idle Up and see if the problem goes away. Nothing obvious jumps out at me when I look over the tunes.

 

Since the car was running I didn't open Tuner Studio until after it was running. I was then able to save my tune and the message went away. I have no idea what I did. My ac isn't working but I think I lost freon. Compressor not turning on, not MS related, I don't think.

 

Just an update. It was in my computer settings that stopped the ac from working. I couldn't figure out what I did wrong and loaded an old tune. The car starts and runs well, with the ac also working. I'm having real problems getting to know the art of tuning. I can barely understand the basics.
