PCM/ECM FAQ

Q: Do I have to have my PCM/ECM tuned to use a standalone harness?

A: Yes.  All standalone LS and LT swaps will have to have the PCM/ECM tuned to remove VATS and all other non-used items that are programmed in from the factory.  There are NO EXCEPTIONS to this rule.

 

Q: I have a 1997-1998 LS1 PCM, can BP Automotive build a harness for this PCM?

A: The 1997-1998 LS1 PCM is prone to failure and has become rare and expensive as a result.  Moreover, these PCMs have their own pinout and BP Automotive does not build harnesses to utilize the 1997-1998 PCM.  We recommend upgrading to the 1999-2000 09354896 or the 2001-2002 12200411 PCM.  These PCMs are far more common, and much more reliable.
