I am new to these forums and certainly new to any kind of computerized tuning. I purchased the HP Pro Tuner and I'm just plugging it in and familiarizing myself with navigating. I have not and I will not actually do any changes until I get more familiar with what I'm looking at. I had a local shop do the initial tune but they were having some difficulty getting everything right so I bought my own setup.
My project is my 2007 H3 Hummer which I have had the gutless 5 cyl ripped out and a crate 6.2 LS3 put in. The stock tranny was rebuilt with this high HP engine in mind.
As you can see from that second video my biggest problem is with the jump off the line. The engine stumbles and doesn't really catch until it gets past 1500 rpm. I was told this is due to the very aggressive cam in this engine. It has gone through about 3 different "tunings" and the first time I drove this monster it literally jumped off the line. Then it changed and it could hardly get moving down the freeway so I took it back and they worked on the tuning some more and got it to where it runs pretty good but off the line stumbles.
Anyway, I'm not really asking for help with this specific project (as I have not provided any real info since I'm still trying to get familiar with the HP Pro) I'm just introducing my monster to y'all and sayin' "Hi".
I'll spend some time in the forums trying to figure out how to use my new tool (and of course I'd love any pointers for newbies)... I'll update as I make more progress.
