    SBEC2 V6 vs T1

    It is known that V6 SBEC2 can be rechipped to run a 2.5 TBI. My quest is to determine if it can run a TII
    Most of my SBEC2 V6 use PCB board, 4517652 which is the same PCB and Logic chips as my FWD Stage 5 SBEC2. The same PCB and drivers chips also used in a SBEC2 MPI(??) that I have B4639557, this may be an easy conversion. Just Rechip???? Edit: B4639557 is missing two of the Driver chips under the heat sinks so it is unlikely MFI as was listed on the hand written label. The board is also missing a few minor components.
    I have noticed a dozen or so passives smd component that are different on the V6 vs Turbo. I will document the differences and post.

    I think I have a V6 SBEC2 that's NOS still in the box in my basement. If you need pictures, etc. please let me know. I'd like to get my $3 out of it some day.

    Was the Flex fuel SBEC2 a V6 ECU?
