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 ?
