A linkage stop is the way to go like Tom says. Assuming of course you have linkage and a separate throttle position sensor (TPS). The TPS needs to know when the stop is on so that the ECU can change the fuel accordingly. If the TPS is hooked to the throttle body throttle plate shaft, it will get the signal right when the throttle stop kicks on.

Not sure how much tunability you have on the EFI system; but you may want to be able to adjust the amount of fuel while on the stop. Also if you are running it in closed loop you will have difficultly predicting performance because the ECU is adjusting based on temp, pressure, o2, etc. You would be better off to get the tune up right for the track you are at and run in open loop.
