LX9 OBD2 PCM tuning support is finally here! (BETA TESTING) (Page 1/1)
Darth Fiero APR 04, 02:18 PM
I just obtained tuning software that supports a few LX9 (3.5L non-VVT) applications:

2005-06 Buick Terraza 3.5L LX9
2006-07 Buick Rendezvous 3.5L LX9
2005-06 Chevy Uplander 3.5L LX9
2005-06 Pontiac Montana 3.5L LX9
2005-06 Saturn Relay 3.5L LX9

I know many of you have been waiting for this. However, consider this to be in the BETA TESTING phase, as I have zero experience tuning these particular OSs/PCMs. Therefore, I would be willing to work with one or two of you who is using one of these engines (preferably with a manual transmission) using one of the above supported OE GM OBD2 LX9 PCMs. I'll provide all tuning services, free of charge. I would ask you split the shipping costs with me, however.

Email me at sinister1880@gmail.com if you are interested.

Maybe. There aren't very many tunable parameters for these applications, so I'm not sure if I can make one of these PCMs work with a manual transmission correctly. I'm also not sure if the tuning software can disable VATS correctly either (which is why I need a BETA tester).
