Blackbear tune ordered

[Joseph Garcia]

There are specific USB dongles that will work to connect a Tech 2 to a PC, and a few posts on here list at least a few. Sometimes the Tech 2 needs to know which COM port the dongle is using.

To mirror what @Joseph Garcia notes, the online Techline, or whatever it is now, connection through the PC is generally not needed to troubleshoot. Typically needed only to program.

For dongles that are known to work, see these two posts:

EDIT: for programming info, see this thread:

Migration from ACDelco TDS to GM Techline Connect for Tech 2 Users

Hi Folks, As you probably know, ACDelco TDS (TIS2Win) site for Service Programming Software (SPS) has been retired, effective September, and current subscription holders need to migrate to its replacement GM Techline Connect. Below, I offer you the process that I used to perform this...

And, even if you have a need to program a control module using the Tech 2, you still do not need to install the supplied software. Programming is achieved through a dongle, as @Fless stated, to connect the Tech 2 to a PC USB port. However, connecting to TechLine Connect, the source of programming data, is achieved directly through a web browser on the PC, such as Chrome, Edge, etc.

In this case, it's only been a week. Give it another week or three.

Meh...

Yep 2-3 weeks.

The update on the black bear tune I ordered. Apparently my file was corrupted and I had to call them after 10 days or so asking for an update to find that out. He did send a custom tune but said he couldn't see hardly any of my file. He did mention the octane I should use 89 instead of 87 so it would ping less. At that point I was pretty confused cuz I want a full customization of my vehicle. So after clarification, they are going to look at the custom tune after running it for 20 to 40 minutes and make adjustments?. The AFM is disabled which is great, it also seems to be a bit punchier but that could be in my head. Still waiting for the full custom tune file. Updates to come.

They sent you a canned tune with their general changes made to shifting, AFM disable etc. You’ll have to re-log and wait again after sending it in. Lucky you called or it might have been longer to find out. Patience is necessary when dealing with them.

I sent the log file last night. Hoping this one's not corrupted. In your opinion, what difference do you think on notice between the canned custom tune I have versus the full custom one they'll send me?

I have no idea. It depends on a lot of things, too many to even list.

It's going to improve as you drive it, especially the transmission. That's my favorite part.

As for performance, my LC9 is rated at 310 SAE Net Horsepower. I see guys with camshafts, tunes, exhausts, headers making 270-280 on various dynos. Mine made 307 Rear Wheel Horsepower through the traps in the quarter mile. Basically smoking those guys. Last time out it was a little down on power, 296 HP, I think the muffler is falling apart internally as you can hear the whoosh as she races by, the sign of a restricted exhaust.
