Need hptuners 3.x tune file

[warriorpluto]

Does anyone here have an stock or slightly modified tune file for an 2007 trailblazer 4.2? I need it for hptuners any version that's not 4.0+. I was trying to tune and it soft bricked my ecm with an timeout on 4.0 so I want to try version 3.7 of hptuners I have instead

Although I have HPT and a 2007 TB, I don't have a copy of either the original tune file or the current tuned file (by Limeswap). I could try to download it from my truck. I haven't updated HPT in a long time so it's likely an older version I have.

Nix that. I have an HPVI2 and it doesn't work with older versions of the VCM suite. I currently have version 5.0.4

Maybe @limequat could help you as he's been tuning these things since forever.

Or maybe this is your issue?

First time with HP Tuners, seeking advice for getting started

I plan to also use this on other vehicles in the future, but curious to get my feet wet with the 02 Envoy, I figure this will also be a good thread for anyone diving in. The program seems straightforward despite the learning curve. I have a spare PCM from an 04, this was going to be the "test...

Thanks a lot moose man. What I end up doing was rolling back the firmware on my mpvi2 now I can use 3.7 again. Hptuners forces an update on anything newer than 4.0.8 even if it's not connected to the Internet. They try everything to block older versions because of an hack by a Chinese guy for unlimited credits back in 2018. Very nice to have lol.
