Hey all,

In my 2008 Silverado, I'm swapping an 6.0L LY6 in for my 4.8L LY2 (and swapping over the turbo setup, but that's a different story...).

I want to use my HPTuners to just flash my current ECM (OSID 12617631) with an LY6 tune, but having searched the HPTuners repository and threads, I still can't find a tune with the right OSID. They all seems to have OSID 12622142.

If anyone has a 2008 2500HD 6.0L gas tune for OSID 12617631 for HPTuners they could send me I would be very grateful!

My other option is to buy the ECM from a 2008 2500HD 6.0L engine, but there aren't any around me, I'd rather spend the cash elsewhere, and I don't want to have to wait for one to ship here!

If anyone has a better option I'd be very happy to hear it!

Thanks!

 

local used car lot. . . and go for a test drive

stealership . . . . find a VIN for the year model that you want, give them the VIN and they will flash the tune on there

Or find someone with a new MDI (tech2) and reflash it

 

The tricky part is having it match my OS ID ... I can't just have just flash any tune to my ECM, it needs to match my OS ID, doesn't it?

Thank!
