E39 tuning support was first released by EFILive in 2010 gaining us the honour of being 'first to market'.  Fast forward to 2013 and this controller has received some major revisions from the factory and has been renamed the E39A.  Once again EFILive is 'first to market' with tuning support for this new controller further cementing our place as the industry leader of GM Gas support.

EFILive's public software release on April 23rd, 2013 delivers support for a range of 2013 Chevrolet, Cadillac, and Buick models as well as the 2014 Chevrolet Impala now using this ECM (yes 2014 models are already being delivered!)  The E39A controller required a full development cycle given the differences to it's predecessor the E39 ECM.  Complexity differences aside, customers can be assured that our first release is all encompassing delivering all of the essential tuning tables to gain maximum performance. 

Customers need not worry about which version of the E39 they are tuning, EFILive will automatically detect the ECM type for you.
