EMS????

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

I've only every seen stand alone systems in Toyotas, but all of those have been for track use only. It would be time consuming, but maybe worth it to just fab a system that would allow you to change between OBDII and custom control for the purpose of an emission test.
