not sure if actually did the wiring for this mod yourself?
but i think i found the answer, when tunning using SCT Xcal 3 Handheld Tuner an option is available to turn traction control on/off

Actually I looked everywhere to do this and no one seemed to know, so I did my own research and did it myself!
This disables the auto4x4 mode to keep the RWD mode only...
This is different than the traction control, since the traction control of the SF3 only modifies the traction control, not the actual 4x4 system. The traction control just limits the engine power when it senses slippage in any tire, therefore cutting down the accelearation so the tires will regain traction. The Auto4x4 in the other hand, will engage the 4x4 system if it also senses slippage, autoamatically putting it into 4x4.
My mod disables it from going into 4x4, keeps it into 4x2 RWD mode but the traction control is still active which means the engine will cut down acceleration to gain traction, but if you press the traction button to turn it off - it ill disable the traction control, but only up to 45MPH, so in hence I can do a RWD burnout up to 45MPH lol.
Now this is where the SCT programmer comes in - to change the traction control limit higher (since I think you actually cannot disable it but change the value) change it to a higher speed like 199MPH I think - maybe higher not quite sure - so then you got all the power in 2WD with no limits (well up to the max setting of 199MPH - i think or higher) unless if you can do a burnout faster than that then - more researching ahaha
Pretty my mod combined with flashing the PCM gives you full accelearation in 2wd!
