To reset the EFI ECU, pull the EFI fuse and pump the brakes a few times to drain whatever power is left floating in the system (I usually leave the fuse out for 30 mins) then replace the fuse.

Or, specific to a 1JZ-GTE (might work for others, but cannot verify) open the DIAGNOSIS port on the engine. Short terminals Ts and E1 with a paperclip. Start the car, you should see a dot light up next to the clock (on a Soarer digital dash anyway). Turn the car off, remove both terminals from the battery and leave the car overnight with the short in place. Return in the morning, remove the short and re-connect the battery.
(Courtesy of LSOC forums).

I haven't tried the 2nd option yet (not enough time), but the first one does work and I have noticed a difference.
