I just found this great post at Toyota nation about how to bypass the ECT and set up a manual shift switch with on demand TC lock up.
The Free Mod Series: Part VIII Electronic Transmission Controller - Toyota Forums :: Toyota Nation
You can set up a 6 position rotary switch that give you the ability to change gears at will which is great for FE because I will be able to shift up sooner.
It's just at the limit of my skill level although I might start with the TC lock up first for simplicity.
