Cranky's 2ZR-FE swap

[tmontague]

Cranky: do you have an immobilizer? I'm wondering what the difference would be for parts if one does the swap w/ an immobilizer. I'm assuming needing an ECU with an immobilizer plus the correct wiring harness

In Canada most all Toyota's after 2007 came equipped with a immobiliser,I though initially it was just a matter of buying a American xd ECU with out a immobiliser but failed.(car no start)
After some research found that on immobiliser and non immobiliser engine wiring harness are the same but the body wiring harness is different,figure there is something in the harness that tells the engine ECU that there is a immobiliser ecu.didn't want to deal with dissecting harness so ended up changing engine ECU ,immobiliser ECU and keys( had to change second gen g keys).
NOTE: if you doing the swap don't use yaris shift cables,there too short(they will work),The new mounts push the tranmission forward by 2 inches ,ended up ripping out the studs off the body which hold the cables,two holes in body had to weld the studs back in.

I'm confused as to what you did to get the immobilizer to work with the 2zr?

Are the 2zr shift cables compatible?

Yes, my 09 has an immobilizer. The research that I've done indicates that none of the US xDs came with one. - Caveat! My wiring research shows the 11+ wire harness as being wired for IMI/IMI signals. This could be to accommodate the Canadian requirement with a single wire harness. At toyodiy.com, there are no part numbers listed for the key transponder or key ECU. In the wiring diagrams, there are no immobilizer lines on the engine ECU (needs to be verified for 10+).

All that said, I want no part of screwing with matching keys to ECUs and stuff. The non-immo xD ECU will work just fine as long as the Yaris' key transponder K-line (brown wire) is disconnected. (Also needs to be verified)

sorry I have not been reading lately but that was the first thing i tried was to disconnect imo and imi and run an american 2008 Scion XD ecu.tried it twice thinking the wreckers had broken the first one but both times there was a code for a mismatch ecu.Then I tried taking out the immobilizer ecu and then running an american xd engine ecu but this was also a no go.
So i came to the conclusion that there is more to the wiring then shown in the diagram,probably to prevent people from stealing and reprogramming your car. (the car would crank but would not fire up)
After this i decided to use a Canadian 2011 scion xd ecu with my 08 yaris immobilizer computer.This is where i screwed up ,when i de pinned the connector I elongated one of the pins(imi) so that it was no longer making contact with the ecu .(car would fire up for a second then die.) Thinking that the immobilizer ecu was incompatible I changed it to a 2011 immobilizer computer and key but still it had a communication error code . Then i retraced what i did and realized i needed new imi and imo pins .After I replaced them the car started up right away.I think I tried to start the car too many times with the screwed up communication lines because it locked me out,So it may work with a scion xd ecu and a 08 yaris immobilizer computer.

CAUTION
-After you get your ecu you have 10 tries to start the car before you are completely locked out from the immobilizer ecu.So it is very important to get everything hooked up right otherwise you could be buying another immobilizer computer.
