Seems that the 1993 is using the last generation OBD1 ECM's.
Kinda like a OBD 1.5 version....not as smart as the obd 2's....
.
The 4L80E has a control box that is piggybacked off of the ECM. I recently found that Howell makes an ECM w/wiring harness for the FAST TB w/4 injectors for the 454/502. It will support up to 600hp. Now just need to gather up all the pieces for the engine swap. Next I will need to learn what I can about Data Logging to fine tune this combination.
Thanx for the input MalibuVLX
