So if you flash it into the truck, then scan it into HPT you can’t look at the tables? That sucks.
Yeah, I'll be trying that when I get a chance. About a year ago that still worked, hoping it still does. ...the way things are going, im not sure ill be getting the blower on this year.
That's stupid, I don't understand how they can do that.

IMO a tune should be a tune, period.
It's literally only for emissions legality.
I heard Cali is making it so you won’t pass emissions if your tune isn’t stock. What have you heard Wes @Doubeleive ?
Yup, started a few weeks ago I heard.

Too bad that the mass exodus of businesses from California hasn't woken the politicians up.

Doubtful, that would take a ton of software from every make and model and variation out there to enforce it, I haven't heard of this at all and I tend to stay on top of most of the news. Besides they already have C.A.R.B. anything that is modified has a number and they just punch that in to confirm it is compliant, this includes canned tunes.

this is apparently a recent turn of news events, I have a hypertech with a carb number, I wonder how they are going to differentiate between the carb approved tune and my blackbear tune? I guess I will find out next time I go to smog and give them the canned tune carb number lol.

They would need quite the database of tunes to compare against.
+ different versions etc.
I understand what it would take, and i don't see them doing it.

That said, the guys checking my hoe out seemed to be fascinated by the only place that you can read the "AFR" logo on the passenger side cylinder head.
red valve covers might have been a little too flashy. :jester:


ETA: In the fsm, they talk about what it take to compare a stock tune against one installed for warranty bs.
It's a pita.

It’s true as of July 19 but if the tune is CARB compliant you’ll pass. Also you can flash a stock tune, pass emissions, then reflash your custom tune. This would be no bueno for me since my Denali would destroy the engine trying to pass emissions.

There’s lots of articles about it out there, surprised you haven’t heard. I don’t know how they detect the tunes but supposedly they can.
