A343F tiptronic / shifter swap. KZJ78 1KZT

Postby kbushnz » Sun Mar 19, 2017 1:33 pm

Hi all
Been playing in the garage again this time with the shifter.
I have no TCU as went manual pump a long time ago.
Stumbled across a TCU in aussie and got one shipped over.
With the guy who made it we altered the program to use with my setup.
I had to put a new TPS unit onto my throttle linkages.
Also play with the speed sensor.
Had some big issues with this as the factory unit in my truck is a reed switch and the TCU software didn't like it (switch bounce)
Ended up swapping the reed switch for a Magnetic hall effect switch. Had to strip speedo apart and remove reed and graft in new unit.
Then rather than having switches to go up and down thru the gears, I adapted a Subaru Legacy sports shifter so I can used its tiptronic feature.
Here a a few pics of the install.
They dont do it justice... Lots of trial and errors...
Machining, welding, grinding and rewelding hhahah

I had to pull the speedo part out of cluster. Remove the old reed switch and then dremel the place where the reed switch was to hold the new hall effect chip. And get it in the sweet spot to trigger the unit.Then screwed and glued it in place. Run wires and install back into cluster.
Used one of these.

Cheers but not my work....
There is a little man in Aussie who is playing with them.
I have just installed it and with him tweaked it thru software updates to get it to work in my Prado.
He is now playing with making it fully automatic....

wow Calvin, again you show leadership in the tech department :-)

how did that work out?
you were manualized before, so what is the big catch here?
