I threw a ls7 tb on my maggied 5.3 today. Pulled a tune from an ls7 vette to get the etc scalar data, but couldnt find it? Only the throttle maps which i understand i shouldnt mess with? Is the scalar labled different in gen iv pcms?

For this it's under idle airflow.
Found it! Thanks! What all should I change for the ls7 tb? Ive re dialed the maf and changed the scalar, but it still acts a lil funny occasionally. Seen a lot of stuff in the ls7 airlfow tables different from mine. But im not sure which is due to the tb and which is due to the completely different engine/platform?
Only real issue is that its a lil slower returning to idle, kinda hangs when you rev it. Im gonna reset the idle learn tonight and see if that helps
Did a throttle cleaned reset and so far so good
tuning your base idle airflow will help with the hanging rpm situation
