A little background info; I have a 2005 GMC Sierra Denali fitted with a Bi-Phase liquid propane injection system. (6.0l LQ9 engine.) This system replaces the gasoline injectors with liquid propane...

Thanks Bill.

Lost my interface cable, and bought a new one. (Yeah I know, dumb-a**) Uninstalled the old HP Tuners program off my laptop and re-installed the program with the CD that came with the new cable. ...

@sweets10v8: What issue of GMHTP? I'll see if I can find that issue.

I too have an '07 L92 out of an Escalade, delivered with engine harness, but no VCM. I'm looking at what is involved in...

Since first posting this thread, I've poked around Full Size Chevy and LS1 Truck websites and garnered a lot of good information. Looks like the 5.3l is a slam dunk, the 6.2l is a considerable amount...

Ok, I have an 03' Sierra 1500 with 4.3l V6. It's been a fun truck but now it's time to upgrade the power a bit. I bought the unit as something to tinker with and I have other vehicles to use as...

Seems to be particular to the 4L60E.
Bugs the heck out of me. I get half way to work before the T/C locks. (12 km trip.) In the winter, it won't lock at all during my little commute.

Just as the title says, the ability to adjust the minimum coolant temp that the torque converter locks at, would be handy.
People trying to get maximum fuel mileage prefer to have the T/C lock as...

Guess not......

Do we have the ability to change the minimum coolant temp that the TCC locks at?
My truck is a commuter, going for maximum fuel mileage. I start it up and drop in gear. Waiting to hit the min...

Well, trap speed is a clear indicator of effective rear wheel horsepower. If your trap speed goes up slightly with a 4900 rpm 2-3 shift, then it is a change for the good. I would suggest back to...

I bumped my shift points after installing the '92-'95 "W" cam, which has 208*/208* @.050" .435/.450" valve lift. (Stock cam is about 195*/202* @ .050" .425/.435" valve lift.) It seems to like 5300...

tiresmokinv8: Good question. I've raised mine to 35* @ WOT, and no KR. (On 87 octane.)
Same deal as you, I've lowered a couple points 2* at off-idle and low rpm cruise, but at the higher rpm's...

Bill:

Finally cured the "Invalid date/time" issue preventing me from saving, and going back into my files. Turns out, I was designating a day of the week in the time/date. i.e; Sunday, May 11,...

Bill,

Thanks, 'preciate it. I'm sure I'm just missing something simple..........

My desktop computer is running Vista Home Edition, and opens all the files just fine. My laptop is running Vista Business...

pm'ed you.

My laptop will not open the "new tire, ac mods" file. The "OEM" file opens fine.

Oops, forgot to attach the stock tune. See attached.

Stock tune may be of value to the repository.

PM me if you like, so this thread can die naturally.

Thanks for the help.

Currently, I'm set up on Arizona time. I'm located in a small region of BC that never changes time, thus, I select AZ, which happens to be the same as us here.

See attached stock and modified...

Doing something a bit different with my truck. 2003 Sierra 1500 2wd, short box, extended cab 4.3l V6. I bought the truck solely for the purpose of proving a point. I don't need another truck, just...

No go. My time zone was ok, and computer clock set to hh/mm/ss. (Non-24 hour military type clock.) Tried re-naming the files under every time option available in the control panel, and all are no...

Great, thanks, I'll give that a try.

Hey all, just tried my HP Tuners for the first time, and have a newb question;
I can download my OEM tune fine, and can edit it ok, but when I save the modified tune as a different file name, I...
