I am referring to the chip swap how-to to replace the TB chip when upgrading.

Via Micro Image...

larger TB = more air = ECU sends more fuel = more power for the same a/f ratio.

1. drill out the rivets on both throttle bodies.
2. chip away the sealant from the idle adjust screw on the 1ZZ throttle body.
3. using small bolts and nuts, install the chip (black plastic assembly) from the Yaris onto the 1ZZ throttle body.
4. install the 1ZZ throttle body onto the Yaris, adjust idle screw

Thanks, do I have to take the TB out to get to the chip? Its already in there and I have the chip ready, just need to do as you mentioned.
