ECU Programming to bypass SAI test?

Greetings all, this one is for the coders/programmers out there (AceFX included )

I have been reading a LOT about Carbon build up in the heads clogging the ports for the Secondary Air Injection system which ultimately throws P0491/P0492 codes.

I've also been reading a LOT about Tuning solutions, from places like Evolve, ESS Tuning and apparently quite a few others that provide ECU programming for 'performance tuning' purposes, which also (in most cases) specifically disables the SAI test in the ECU thereby clearing, and eliminating, the P0491/2 faults, and all for anywhere from $300-$700. This is heralded as a preferred solution for carbon clogged ports for SAI since all other means of resolving this issue includes $$$ and pulling the heads, and since it has no bearing on life, performance or drivability, it seems like an ideal approach to a widespread problem.

Therefore, my question is: does anyone have any idea what needs to be reprogrammed in the ECU to resolve this issue? and can this be done with a tool such as the one AceFX has been using to basically completely recode his entire car from pre-to-post facelift?

Interested in hearing what the coders/programmers out there think about this....???

European version doesn't have SAI.
If you simply install European ecu flash it should do it. But I'm not sure European cars even have those smog tests .
