Just purchased a 2009 Hummer H3T with the inline 5 cylinder and automatic transmission. Of course I plugged in my V2 (black) and downloaded the tune. When reviewing the tune file there was a warning not to mess with anything that had variable valve timing. Since all these Atlas engines have variable exhaust valve timing I take this to mean a shouldn't fiddle with it.

So: The LLR is not supported? 2009 H3's with the 3.7L are listed in the supported vehicle list. I'm getting conflicting signals.

Where is the warning about not altering VVT tables?

When I first open the tune file and I first open the virtual VE table. I did just run the check for updates and firmware. Said I was current.

Ah ok, I see what you are saying, that is to do with the virtual VE tables, I won't go in to long winded explanation about the Virtual VE tables and the variable cam engines, but don't fear, if you have no intention of altering the VE tables in the tune then the warning can be ignored.

Wife will be happy when I tell her you said I couldn't turbocharge the Hummer.
