I?ve used hptuners on my (otherwise stock) 2012 5.3L Sierra with the 6l80 for the last 8 years. I?ve noticed strange behavior when I do any trans tuning.

After I modify any trans table, and then...

Thanks for sharing this tune Russ!

I've used parts of it on my 2012 and been very impressed.

I don't claim to be an expert in anyway, but I am trying to learn and have a question. Did you not...

Thanks!

Is there a reason that sometimes when I copy a table from one tune into another (by selecting the whole table and copy and pasting) that later when I do a "compare" it flags the tables as different...

Thanks Fish - appreciate the mentoring

Here's an updated log file.

Yesterday, I loaded the file yesterday with the reduced final shift on the 3-4. Today when I was driving home from work, (as previously stated) the 3-4 felt better at...

Fish, I ended up reducing all columns by 10%. It does seem better.. Most of the time.

I only did this in the "shift final - normal" table, and not the special table.

It seems like under...

Hey Fish - Came back around to taking another look at this. Not sure if I'm understanding your previous posts correctly..

You're suggesting I decrease the values in columns 1-5? So when I...

Ok, thanks fish. I'll look into that and get back. I haven't been motivated to do it and drive and get logs mainly because it's been about 4 degrees and the snow has been falling for days.

cu - Wait, it's not supposed to be that way? :doh: Ok, now that's fixed lets move on to the next thing.

Fish - The shift torque factor on the 3-4 shift is set to .5000
To see if what you are...

Good call fish, that did help.

However that 3-4 shift is still "slower" than the rest? When I say slower I don't necessarily mean the changing of years is slow. But what I mean is there is a...

Help a new guy out!

I have a 2012 sierra 5.3, 6 spd auto - new to tuning.

Make a long story short, the lack of throttle response from the vehicle off the lot got me wanting to make some...

My wideband is in the log, its under MAP and MAF in the Chart Display.

I saw the PE set to <12 afr, but according to my log, it never goes that rich. Maybe the wideband is off? I got the PLX...

Hey, thanks for taking a minute to look.

This is a dynotune from another cam I had. Not really happy with how the car runs, so I bought HPtuners. I've made some minor adjustments and believe I'm...

Don't put me in the drawing. I already own the book. Anyway -

"I'm somebodies Bitch!"

"You guys gotta get me out of here! There's this guy Nasty Nate who wants my cocktail fruit, and everyone...

I'm interested. Are you taking preorders or how would one go about ordering?

I was having this same problem until today. I thought that was the issue, then I found this post - sure enough it works now.

Thanks for the help! :chug:

Thanks for the replies.

First - I am not sure if I wrote that unclearly, but I am no longer running the ASA cam, I now have the one in my sig. Makes good power with current tune 390rwhp

I'm...

I just got HP tuners, just looking for some initial thoughts.

The car was dyno tuned with a cam other than what I am currently running (ASA cam at the time 226/236 .525 110lsa)

Well I know it...
