Like many of you I am an “Old School Guy”, had my share of classics and muscle over the years. 5-years ago I had a shop install an engine / trans package out of a 2006 GTO along with a bunch of other upgrades into our 73 RS / LT / Z28. I’m really struggling grasping the electronic engine / trans management and it sickens me every time it needs something repaired seems no less then $500 and it is ALWAYS something related to the engine/trans management. It’s time to replace the 13-year old system install one of the smart self-learning engine management systems. Looking for feedback of the options out there you have installed, unless there is something new out there I realize the DBW has to be replaced with a cable, please reply your experiences there also.
