2jzge Vvt-i Wiring

[teamdrinkalot]

I am wanting to install this motor and am looking for any advise or clues. It is 2JZGTE VVT-I auto, from the Canada.
I want to run the standard computer and fit a manual box to it.

I don't know where it originated from but I bought it from Canada and it's sitting in my garage.
I am going to fit it in my Hiace SBV.

I have already fitted a 2JZGE VVT-I into my Hiace and have completed 50,000k's since install

I went after market computer with this install just for ease of installation and tunability. At the time I did not understand how the VVT-I worked and I took a hit.
My ECU could not control the VVT-I so I locked the inlet cam at the same setting as a non VVT-I 2J, but I feel that I am not getting the best out of this motor. It makes power from 3000 - 5000rpm.

My insurance company said they would not charge me much more for a Twin Turbo upgrade, so instead of mucking about with current 2J - I thought I might as well go the whole hog.

Hence wanting to keep the standard ECU to get full benefit out of the VVT-I. Because it is a Hiace and is a work truck, I need low down power. My driving power band is 2000 - 5000rpm. My van weighs 2500KG's.

I have read up on after market ECU's that wreckon they can control VVT-I, but I am not convinced, they are all concerned about maximum HP, and don't seem consider low down stuff.

So I am looking for ECU pin out's and or any wiring diagrams, also info about can I just stick a manual box on or does this present dramas with the auto ECU.

I would be a bit concerned about whether it has security built into the stock ecu

I'm running an Autronic SM4 on my 2jz-gte vvti. It hasn't had its final tune yet, so vvti is not enabled, but people have had success tuning vvti for the autronic. The new Wolf apparently does vvti, but I haven't heard of anyone actually using that function.

And, of course, the Motec is always an option, if you don't mind getting ripped a new one.

that's just blantantly ignorant, it depends a HUGE amount on the tuner

haltech also controls vvti. using standard managment seems like too much work and a headache, you will probably have to keep all of the factory shit like , egr ect. for it to work properly and when your up the highway with an eletrical problem who are you gonna call?
most aftermarket managment systems have good technical support wich is in english and only a phone cal away
if you want low down power use a small turbo ie t3 with a small exaust housing, short cooler piping and only small piping 50mm if your not worried about max power
good luck sounds like a nicer conversion than the GE

Autronic:

7psi, no vvti:



18psi, with vvti:


same tuner, same dyno. vvti gave a very nice fattening of the low range, and made driving off boost (and thus getting good fuel economy) an easy thing.

I am also swapping a 2000 2JZGE VVTi into an older vehicle. I'll report any info that I can find.

AFAIK, the jdm does not have the immobilizer. I'm going to try to find one if I can.

I am currently searching for a 1998 toyota supra 2jzge ecu. That year had the 2jzge vvti, and might be a better option with less restrictions. The part number is 89661-14731.

Here is a picture of a JDM ECU:

good luck dude - there weren't very many 2jz-ge vvti supras made

Good luck,

Yahoo.jp should have a few ECUs... ... EDIT: nope, the part number you listed is for USA JAZ80...

Btw, I might be able to sell you an electronic copy of the JDM JZA80 Electrical Wiring Diagram book if you are interested (Prbly not if you are after a USA engine ECU)

I have a 2JZGE VVTi ECU here with part number: 89661-51011 , I believe from a 2000 JDM (I think?) model Toyota Progress (last time I checked - going off memory atm). Unlike the ECU in your pic, it has the additional plug at the end with 6 wires. This ECU was supplied with a motor apparently from a USA based model, I haven't really bothered looking into it all thus far, but am interested to read your findings?!

Clint, I'd be interested to buy or borrow your ECU to find out the internal differences. Someone else with the same problem ended up buying a JDM ecu to bypass the immobilizer.

I've been reading around, and so far can't find any evidence of an immobilizer in the Supra VVTi 98 Supra.

I did find an engine w/ ecu, but no pictures of the ecu as the seller will not be back until next month.

Wilbo, the part number I posted is the USDM ECU. The picture is of a JDM ecu. Thanks for the offer, but I don't "buy" online documents.

You're more than welcome to buy it and scan it in yourself like I am doing then If you find it online I'd be quite impressed

I'll be asking a very modest fee, more than anything to cover the time taken to send it to people

Not overly keen to sell or lend it out atm, but more than happy to take a few pics of the circuits if you'd like to reference them?

[cambelt]

Theres no way id lend a ECU for testing purposes as if the car its fitted to has any faults, or isnt wired correctly it could fry the test ECU . You may just fry 1 circuit and it keeps working but its not until later you will find out what circuit got fried.
Someone in the world may be able to prgram toyota ECU,s in regards to the security parts but finding that company/person will be a hard task.
