58 with a LS2 with half throttle....

[wutnxt]

So this is my first LS swap and i have learned alot and i still don't now anything.......

Started with a 2007 trailblazer LS2 AWD....I tossed out the AWD and swapped a 4L80E and ordered a howell harness to run the 2007 trailblazer ECM and the 4L80E . So we had some harness issues nothing was labeled and some of the wires wee backwards but hey it happens. So we went in with HP Tuners and set up the engine to run.....we had topost for the tranny download which i am waiting for so it still thinks it's the AWD I guess.

But here is what happens so far...

It fires up and idles and runs awesome....But you have to roll onto the drive by wire throttle slowly and even then it shuts down at about half way. It actually does move but it's easy to tell it's not right just yet.

So....is it because the tune for the tranny hasn't been loaded yet ?

........Is it because something is wrong with the drive by pedal out of the trailblazer ?
.........Is it because something is wrong with the trailblazer drive by wire throttle ?
.........Is it because my sensor is to close to my air cleaner ?

.........Did i forget anything else ? It has enought fuel....the pump is working

I hope to load the HP tranny update tomorrow night and start there and see what happens...anyone else ever walk though this and point in a direction ?
