I'm in the process of finishing up my 4l80e swap but I need a to figure out what to do on the HD file segment?


As of right now the 80e trans is in and I purchased the Speartech wire harness with the vss connection. I've done some research and from what I gather I need my tune plus an Hd file that's closet to my tune which I then send off to Hptuners to have them do the segment for me?

The thing is on the Hd file I'm not sure what I'm looking for I've look thru multiple threads and it doesn't really say what to look for just the closet to my tune?

Also which my stock to or my adjusted tune?


How do I attach my tune it keeps saying its invalid?

 

from HPT open your file goto edit and calibration details

whats your OS ID, then you can find a matching 4l80e with the same OS, send to HPT and they will converter it for you

 

Thanks for the response and that seems pretty straight forward but do I send my stock tune or my modified tune or doesn't even matter? Once again thanks!

I would imagine that I should use my modified tune so that when I get it back there's no need to mess with the tune?

 

what ever tune you plan on using on your truck, so you can just do a read of whats on there and use that

 

hijacking....

my VCM OS ID: 1251002

when I click on the box that has the "HP OS" drops down the VCM Enhancements
1 bar map
2bar map
ETC..

Im running the 2 Bar OS and it says beneath that "Converted from 12212156"

 

that im not 100% sure i would think you need to find one for 12212156 though

 

correct.

 

thanks

 

got my new tune (80e) back this morning, Thanks for the fast turn around

 

top notch service!
