24x DBW ECU
All 99+ PCMs are DBW capable, you only need to make sure they are flashed with the correct calibration for the DBW to work.
You also need the TAC module, it's harder to find than a PCM because TAC modules change between years and always get lost or damaged.
the crossing point was ls2 in vettes and some cars and trucks at 06, even the 06 gto was 24x
