You'll have to check into that one...as an 06 engine would likely not run off an 02 tune file.

You don't have the 06 wiring harness???

Also you will need the 06 TCM too, I believe it was 06 when they split the ECM and TCM...in that case an 02 file would be useless, as the ECM held both tunes. I'm not 100% sure on this though...check into that.

But, If you have the wiring harness and both modules you can plop them in your truck...my buddy at work has done it to 3 trucks and a car now. 2 of the engines are late model 6.0L, 2 of them are 5.7L LS1. He did it to 2, 72 C10's an 80's firebird and an 80's pickup.

 

The 06 is dbw and I am going back to DBC with it and a harness from a 99-02. I believe this would easier than sticking with the 06 equipment because I whould have to change more things and prolly run into more issues. By the way I am still looking for an 99-02 drive by cable harness if anyone has one and preferably for a 4l80

 

Check ebay for a harness. I got the exact one you want for $150 shipped off ebay.

I'm not selling one, I bought one for my truck off of ebay...

 

O ok I appreciate the link and yea if u find anymore send them my way

 

I poked through the tune files for an 02 and an 06...not much difference really. Now the signals its actually looking for from the sensors may be very different. I am not sure how to write a new OS to your ECM though..you'll have to look up that one.

I love the simplicity of tuning the trans though....its like night and day between the 4 speed and the 6 speed.
