What needs to be done to the pcm when swapping to 4l80e? Where can I get Files and or info? Can the progrmming be done with hptuners?

 

you need a 4l80e file. the problem is they only come with a 6.0l eng, so your tune will be way off at first. Or you could just over wright your eng tables from your 4l60e tune. Allen did mine for me, so if you have a nelson tune, he might be able to help you out.

If not, I have a 4l80e bin* file I bought from Speed Engineering that I did not use.

 

Have hptuner. Would like touse that if posible.

 

P.M me your E mail. I'll send it
