One of these years (hopefully lots of years) my grandkids in Calif  will probably end up with my pickup.  Wondering if this ruling effects people with adrenaline in California. Law took effect just a couple days ago I understand.

No, adrenaline intercepts the signal modifies it and sends it to VP. It does not change anything in the ECM itself. Smarty does. 

Still, if the tuner is attached to the vehicle and does not have a CARB E.O. number the vehicle will fail the CA SMOG test.  I use to remove the EDGE EZ from my truck before a test 

 

Here is another article about the EPA and diesel tunes.

At least they would need to know how to deal with the Quad if its on there as long they have interest in it.

Alas no one in family gives a rats behind for my truck. None of them are into working on anything mechanical. I am pretty much the only one that parents raised tha gave a hoot about working on anything. Just the way it is for me.

Quadzilla Adrenaline does not flash anything to the ECM. Like @Dieselfuturemention above that it just modifies the ECM signal and send the modified info as a priority message. Now if you build a good tune it will be pretty much smokeless and even better MPG and performance than factory tune could. You would have to either HIDE the Quadzilla completely or just remove it before going for smog testing. 

 

Yes your completely safe with the Quadzilla. It does not flash any code or alter any software on the ECM.
