chpspecial Posted December 22, 2010 Report Share Posted December 22, 2010 Nope; too bad they are not tunable (yet?). Mr. P. EFILive has them on their website as a supported vehicle, so tuning is there for them. they use E67 PCM Quote Link to comment Share on other sites More sharing options...
misterp Posted December 22, 2010 Report Share Posted December 22, 2010 (edited) Nope; too bad they are not tunable (yet?). Mr. P. EFILive has them on their website as a supported vehicle, so tuning is there for them. they use E67 PCM Au Contraire... GM changed their software in the 2010 & 2011 PCMs; when you use EFILive to change transmission parameters and flash your tune everything 'appears' to happen correctly, but when you drive the vehicle the transmission acts exactly like it did before tuning. Delco has apparently changed the transmission segment of their software in the 2010+ year PCMs. This problem is not limited to the CTS-V, also the GMT-900 trucks too - you can tune the motor, but attemting to tune the transmission segment will not cause any errors but those changes are ignored by the PCM. Mr. P. PS - this problem is NOT present in the E67s prior to 2010, HENCE why I said I am shopping for a early 2009 CTS-V sedan - it's fully tuneable with EFILive. Edited December 22, 2010 by Mr. P.

Well P there is a Black '09 with only 14k miles for $47k in Wisky on Autotrader. What color you thinkin about getting? Black or Stealth Gray are my favs, although the Redlines are pretty sick as well. Quote Link to comment Share on other sites More sharing options...
