If you are not going to buy and use HP Tuners to program your PCM then you should go to this forum for programming help with your OBDlink LX cable.

new to LS SWAPS ...thanks for any help.

do yourself a favor, find a local dyno tuner and have the car tuned.
itll cost a big, but youll never have to worry about it again.

learning tuning and buying the hardware is good if youre going to be doing 10 of them this year. otherwise its a lot to learn and its so much easier to drop it off and get it tuned.

Taking the car to someone else is out of the question, what's wrong with me wanting to learn? I already reprogram the computer to work with the 4l80 today and wired the back speed sensor to the red 20 and 21 pins and the front speed sensor to 22 and 23 pins. But thank you for your help
Now I'm getting a P0704 code need to figure that out. Anyone have any ideas? The code is for a clutch switch. My car abviosly don't have a clutch.

If you want any help at all your going to have to post a data log and your current tune.

Well you obviously did something wrong with the 4L80 PCM programming because there would never be a P0704 code enabled in an A/T segment which is what you should be looking at in the calibration. Just turn it off. Exactly what are you using to edit? Tuner Pro and PCM Hammer with that OBDlink LX?

what's wrong with me wanting to learn? .

there is nothign wrogn with learning.
it is a vast amount of stuff to learn.
i suggested taeking the vehicle to a tuner becuase it is doen in a day or two and then you dot have to worry about it. you can just enjoy it and move on to the next thing.
that is all, nothing more than that.
But without your tune, we cant see anything to have any idea what you need to work on.
