DFI and LT1, how many O2 sensors? - DFI and ECM - Third Generation F-Body Message Boards

I'm going to be using DFI and DFI harness to control the LT1 in my IROC. I just got Hooker Long tube headers and need to install the O2 bungs, but I need to know if DFI will use 2 O2 sensors (1 for each header) or just the one like a regular SBC DFI uses. Also which header to install the bung onto? The drivers side or the passenger side?

The DFI should use one. It shouldn't matter which side you put it on but typically it's on the drivers side.

Have you investigated tuning the LT1 PCM. The 95 version with the 8051 pcm is nice box to work with. 94 is an odd year, and 96 and later can be retrofitted with the 8051 with a little work.

Thing is, I already have the DFI coming to me, so no point to search for a PCM now.
