I know tha this has been covered before. I am new to the HP Tuners software. Just wanted to see if anyone could give me a few pointers as to how I can do these segment swaps the proper way without wasting credits. Here's what I have:

2004 Chevy Express pcm "12586243" from a 6.0L with a 4L80E
My car has a 6.0L with a 4L80E and a turbo.

I want to run a ethanol sensor, meaning I have to segment swap to a 2003 Tahoe engine segment, which will enable the ability to use the ethanol based spark table. But I want to keep the 80E trans segment.

I also want to stay dbc, which from what I have read, this pcm will control the IAC valve with the Tahoe segment because it has the correct drivers.

This bring me to the part where I need to go to a 3 bar custom OS. This will require 2 more credits, correct. I have the latest 3.0 version that has the segment swapper function. What is the correct sequence for doing what I need done??????

Thanks in advance!

The only thing I can say is I thought the only 3bar flex fuel sensor setup was a express van setup. My understanding is the Tahoe only has a 2 bar with the flex sensor available. I am planning on doing the exact same thing soon.
