Iv been looking at doing the 411 swap for a looong time now. I think I’m ready to finally do it. However it appears that lextech does not do the tuning side of it anymore and just distributes the pin out sheet.
There are 3 main things I’d like to gain from this swap
1. PCM controlled electric fans
2. Tow/haul mode
3. Delete rear o2 sensors.
Any other tuning improvements would be a bonus
Lex reccomended me to black bear performance. They would be in the $400 range with the 4th of July sale. I was really hoping to keep it in the sub$200 range. Nothing against black bear I’m just not certain I want to spend that much on this project.
From what I understand the base tune comes from a 2002 express van with a l31. Iv seen some available programmed pcms to an express van roughly in my price range but I question how reliable or correct this would be?
Is there any known ways to work with this or get around it? Thanks
