wolf 3d to 1jz-gte

[chris davey]

Urgent!

Jzz30 ecu, ne – and ne are red and yellow. (crank angle sensor) Which one is which? I have the ecu pinouts but no colours.

I have a jzx90 ecu which is different and the ne – and ne are white and orange.

Thanks!

Chris

instant rep to whoever helps!

I'd be using Red as +ve.

[chris davey]

ok, thanks mate

Next question:

Anyone know what colour wires are on igt1-6 on a jzz30 ecu? I have a wiring diagram for the jzz30 to wolf but can't read the wire colours because they are so small.

Alternatively, if you know what cylinders go to what igt output from the wolf (waste spark) So would it be, igt 1 to igt 1&6, igt 2 to igt 2&5, igt 3 to igt 3&4. That is what I think it should be.

[CrUZida]

Don't you still have the factory JZZ30 ecu plugs still attached?

[chris davey]

i have a jzx90 engine.

I have wiring diagram with very hard to read colours and it doesn't have igt1-6 named.

I am pretty sure the colours on the jzx90 are different to jzz30. So I can either find out the colours to the jzz30 and then work out which cylinder goes with which.

Or if someone already knows that, then I have labelled my 1gt1-6 and I just need to know which ones to pair up

Thanks

You have seen this?

[chris davey]

yep, got that one. that is jzz30.

I have the one for my jzx90 engine (same as jza70). But need to know which cylinders to connect the igt 1-3 from the wolf to

[CrUZida]

Umm, JZZ30 is the same as JZX90

[chris davey]

not a chance. jzx90 is the same as jzx81 and jza70 according to http://www.supraforums.com.au/forum/...ad.php?t=16598

and that jzz30 pinout is definitely not the same as mine. Mine is this one http://www.1jz-gte.us/Images/TSRM%20...1ecupinout.jpg

jzz30 and jzx90 are pin/plug compatible and I believe jzx81 and jza70 are pin/plug compatible - if yours is like a jza70, are you sure it's not a jzx81 loom you've got?

If it's got a pigtail, it's an jza70 Supra or jzx81 Chaser loom.

[CrUZida]

I'm with Manny.

The age of the cars suggests JZX81 and JZA70 are the same, and JZZ30 and JZX90 are the same.

I've never heard anyone say JZX90 is the same as JZX81

[chris davey]

I have the jzx90 dash in my car and that came from the halfcut so it must be jzx90.

All I know is that http://www.1jz-gte.us/Images/TSRM%20...1ecupinout.jpg is definitely my ecu and the other one that Cruz posted is not mine.

It doesn't really matter what I have except the wiring diagram I have has the colours for a jzz30. This is the diagram http://soarercentral.com/sc-forum/me...ng_3-46569.pdf

[chris davey]

and this http://soarercentral.com/sc-forum/me...ng_3-46569.pdf

has the 3rd and the 6th as the same R-B????

Your ECU pictured on sf.com.au left the factory on an auto JZA70 Supra.

A few ECU Part numbers I had here for reference-

1JZGTE from JZX90 Chaser M/T 89661-22480
1JZGTE from JZX90 Chaser A/T 89661-22470
1JZGTE from JZA70 Supra A/T 89661-22400

Good question. Wire it up guessing, and if it runs rough, swap it over.
You wont do any harm wiring it wrong.
