san's rock slides I love curvy roads, grew up on one with a blind man behind the wheel, probably where I get my crazy from. The most dangerous part of driving a road like that is Deer, elk etc, small critters just go under.
When I lived in Alaska, I was driving the Parks Highway one night north of Anchorage and came upon a car that had just hit a bull moose. The cops were already there but it looked ugly. It was a mid-80s Oldsmobile Delta 88 and the driver t-***** the moose almost dead-center. The bumper knocked the legs out from under it and it fell back on the hood, smashing out the windshield and buckling the roof back to about the headrests. There was blood everywhere and I can't imagine that anyone survived, but I've always wondered. To this day, I still avoid making long drives at night where there is big wildlife, if I can help it.

It's all about the burn scar from last year's fires that are a bit north of the highway. The ground there got heated up enough that rain can't soak in, so it causes all sorts of mud and debris to move downhill when it rains. And it's been raining there. This will be happening for a year or more, I would bet, and they're going to need to inspect the decking and piers to see what permanent damage has been done. I think that road's going to be out of commission for a while.

Got my tech 2. Now I have to figure out how to use that.
Got my tune from whipple, unfortunately HP tuners has come a long way since I last dealt with other companies, and it's locked up tighter than the gold at fort Knox.
Because "emissions"
I literally can't see any parameters or anything from it to at least copy stuff over to my regular tune... unfortunate.
I just wanted to use their data to build on my current tune as a base map essentially.

I thought you can't modify the tunes Whipple provides. Is it password protected? If not you could do what I did with my BB tune- load it into the vehicle and then scan it with the HP Tuners which converts it to an .hpt file and then you can open it up and modify away.

You can't. It's locked. Can't even look at any tables.

Oh and i finally changed the hoe's oil to synthetic.

crossing fingers that the metal/copper in the oil reduces for the next run.

metal i saw sure looks like the tri-metal mains.

800 miles on the engine now.


I also saw where my slight oil leak is coming from, the passenger side valve cover!!
I have new seals on hand for when i switch to the 7.4in push rods. :cool:

Took the hoe into get emissions done.
No funny business in the tune, but it passed with flying colors. :cool:

Now i can fk with the hoe, get some grounds re-done, wideband, and new NB O2's installed w/o worry.
I heard Cali is making it so you won’t pass emissions if your tune isn’t stock. What have you heard Wes @Doubeleive ?

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.

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.
