HI All,
Ive got a 2012 Fj and have been running a 1KD after blowing the 1GR a couple of year ago.

Engine is a 2012 1kd ex 150 prado using the prado bellhousing and torque converter / flexplate. Engine sits on modified stock mounts and sits right where it should for oil pan / fan / firewall clearance etc
I had to move the trans back 110mm or so due to the longer bellhousing so just modified the stock trans crossmember.

I sent my engine wiring harness and the 1KD harness to Dieseltoys in Australia for modification and ECU unlocking etc , Ive done 30,000 ks or so since the swap and it a good thing, better mileage, more torque, no one else has one etc

The main purpose of this thread is to share some warnings and of the issues Ive had and hopefully get some fixes.

Installing the engine was easy enough, the harness took 6 weeks or so and after a bit of messing around I got it running.

First issues were VSC / ABS warnings ( still not resolved ) Dieseltoys have long ago stopped answering my emails on this , and temp and RPM signals werent working, the later was sorted with s DT supplied CANBUS translator, but installing this meant my OBDII port stopped working for some reason ( still not resolved )

Trans control was an issue, I found out the hard way. I was advised to run the 150 prado standalone TCM, what I didnt realise was that the TC lockup wasnt functioning, nor the temp light ( I assume due CANBUS interface issues ). The trans wasnt shifting right so at DTs advice I tried a 120 prado TCM. Better shifting but again no lockup or temp warning, end result a fried trans.

SO I got the trans rebuilt and installed an HGM compushift standalone controller, a great piece of kit but their lack of and often contradictory install instructions along with below average tech support means I wont be buying from them again.

SO its a good swap, and close to sorted but I see DT in OZ are advertising complete problem free conversion kits, I would be very weary.

Any CANBUS wizards who may be able to help with this would be much appreciated
