I have to accquire 1ggte ecu... how do I know if it is a
generation 3 computer? As I did not get an ecu with the engine 
Does anyone know the part number for a generation 3 computer?

I don't know the model number. If you search on the site, you will find somewhere the number of pins on each of the ECUS. The Gen3 will have the most pins. Also, the plugs on the ECU should be grey.

frim the articles section of the site
http://www.toymods.org.au/1g_versions.html
1G-GTE Versions
First, the obligatory disclaimer. This is from my experiences with 1G-GTE's. It may not be right, but is consistant with what I've seen.
From what I have seen there are three distinct versions of the 1G-GTE. A great way of telling the three types (that I've found so far) is by the colour ECU plugs and injectors.
Version 1: Yellow ECU plugs and Yellow injectors. 0.50bar / 7psi.
version 2: Yellow ECU plugs and pale Green injectors. 0.62bar / 9psi
Version 3: Grey ECU plugs and pale Green injectors. 0.75bar / 11psi
Those interested in finding a front sump should try to look for a water-to-air 1G-GTE... This may not be correct, but might be a good lead.

Thanks bozwon,
I've referenced that article myself. I'm after some more
specific information about the computer as I have not seen one.
I already know the engine is a generation 3 as it has pale
green injectors and grey ecu plugs and fits the physical
description of a gen 3.
Cheers

Apart from the colour of the injectors, which tell you that the Gen1&2 flow 225 and the Gen3 240 cc there are a couple of other ways to checkeasily. Don't rely on the injector plug as they can be any colour.
The Gen 3 has a bigger inlet housing on the compressor side of the turbo. Easiest way to check is that the conneting bolts for the gen 3 are 56mm between centres. Also the big plug on the computer has 26 pins on the gen 3 and only 24 on the gen 2. Don't make the mistake and mix it up with the 7MGTE computer as the plugs for the gen3 are the same. That is a 7mgte computer will plug up - be interesting to see if it works. Also there are 2 plugs coming out of the TPS for the gen 2 and only one plug coming outof the gen3. Also pretty well of the plugs for sensors on the two engines are different.
There are other things but that will be sufficient to tell to two engines and the computers apart.

I'm having slight problems tracking down a gen 3 ecu at the moment... but I've found plenty of gen 2's.
What do the extra two pins do on a gen 3...
Can you run a gen 2 ecu on a gen 3 or is this not possible?

Thanks for everyones help... it's been much appreciated.
Thanks for locating that ecu Oz_craig... I won the bid on that and should have it soon.
I've hit a little snag... no air flow meter or wiring harnes..
Does anyone know of an alternative afm that can be used on the 1ggte? Does anyone have a 1ggte gen 3 wiring harness that they wish to part with?
Cheers

I have a complete harness that you can have for $100 plus shipping. Thats only part of your problem solved. You will also need an injector resister, ignitor and coil. Although a good sparky should be able to solve this for you using a Bosch coil and ignitor.

I currently gotta gen1 auto ecu and would like swap it to manual ecu when I do my auto to manual trans conversion. Do you know if gen 2 manual ecu would work with the gen 1 wiring loom?

ahh i needed to search for 1ggte to find this thread, not 1g-gte 
well ive got one for you, new motor is auto does this have different ecu? cos ive got 26 pin plug but its yellow to ecu, greeny injectors and all different sensor connectors to motor than the old apparent gen 2 motor.
are those bolts on turbo the ones that bolt on the pipe from the compressor housing to the outlet pipes, the two on the side of turbo?

I know this is an old thread but I thought I'd post the gen3 ECU p/n for anyone searching.
Gen3 1GGTE ECU p/n is 89661-24210
grey pin connectors with 26 pin, 16 pin and 22 pin plugs.

The pins are not always the ways to go on the ecu...my has the most pins (26p 16p 22) but its a gen2.. The best way is to check your inlet manifold... if it has a seperate collector and grey plugs its a gen 3...main diffrence is the turbo inlet manifold and the cast block markings...gen 2 is on the side of the block near the exaust manifold..gen3 is near the bellhousing.... thats the way i made sure of it....But to be sure u should know gen3 has two sepearate exaust housing on the inlet manifold...gen 2 two has one

the p/n on my gen3 ecu is 89661-22280
thats the 5 spd version. Grey plugs green injectors etc etc
From a 1990 Chaser so certain that its a Gen3.
