Default ECU Timing Advance Help????

I own a very highly modified 2000 Toyota Solara with a 1MZ engine and
OEM ECU. I have tried several piggy back EMS to hopefully allow me to
add fuel and advance timing among other things.

It appears I can pull all the fuel and timing I want but I can not add
it. I know one person with 2000 Corolla's who has accomplished this but
I am unsuccessful. What can I do to my ECU that it will allow me to add
fuel and timing.

I do not want to go to a stand alone EMS as I do register my car and
the stand alone will not allow me to pass the OBDII scan test.

Please advise

See my car here.
