My ACR is not opening up when I turn the ignition on. I have installed a ThunderMax, replacing the ECM, and the bike has more torque and hp. Could the ThunderMax be preventing or not permitting the ACR circuit to get a charge opening the ACR valves?

 

How do you know they are not opening up?

You write like there is one there. There are two. You should hear a click with the ignition is turned on.

 

did your bike come with them or did you add them. If you added them the ecm needs to be turned on by harley or there is a setting in the thunder max to enable them. When i was running a power commander they clicked when i turned on the key, but now i have a tts and they only enable while its cranking.
