So I just had my tuner load another tune on my car for backfires and such so I now have a dual map and it worked great. But I did not have the switch in my car to swap the maps so I had to order one. Now that I have the switch hooked up and everything I’m trying to use it to swap maps but it isn’t working, the light comes on when you hit auto but I’m supposed to hold the manual side until my check engine light flashes to switch tunes, when I’m holding the manual side I can hear the relay clicking but obviously I don’t have the intercooler sprayer system in my car I’m just wanting to use it to switch the maps, I can’t figure out if it’s the tune or the switch is just not working, or if the relay clicking matters because I don’t have the intercooler sprayer system hooked up can someone give me some help please and thank you!

 

The rom has different options for changing between maps, so chances are yours just needs to be set to toggle off the ICS switch.

 

That’s what it’s supposed to be set at but I will have to talk to my tuner about it then. Thank you
