    Post 1G-GTE tech info/diagrams

    a bit of a collaboration of 1G-GTE tech info seeing as the old forum info has dissapeared.

    firstly, the wiring diagrams.

    1GGTE AFM is interchangeable with the 7MGE but the spring rate is different. ive run my 1g with the 7m AFM and i did notice it ping. i knew it would happen but i just wanted to confirm

    here is a pic of the gen3 ecu



    also a pic of the winged front sump found on GX81 chasers.

    Nicely collated info.

    What gen is the last diagram ( ecu plug) for?

    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
    I'd just like to clarify on this. From what i've seen it's a little wrong. It should be better as this:

    Version 1 : Yellow ECU plugs, yellow injectors, W-A intercooler, 7psi
    Version 2 : Yellow ECU plugs, yellow injectors, A-A intercooler, 9psi
    Version 3 : Yellow or Grey ECU plugs, lime green injectors, A-A intercooler, 11psi

    Instead of ECU plug colour, the best way is to count the pins. I don't have the numbers handy, so i'll update it later. A Gen2 loom will run on a Gen1 ECU, but will complain about the water pump not being connected. Either of the Gen3 ECU's will be happy running on a Gen3 loom, i've not noticed any difference between the two.

    My Gen2 ECU would boost cut at about 14.5psi. My Gen3 ECU would boost cut at around 15psi. With 3 notches tighter on my factory AFM spring, my boost cut is a little over 18psi without many adverse affects on drivability.

    Nathan, define: "many"

    Basically from this, i take it that the standard fuel mapping under boost is that rich that you can run an extra 3psi on ~same fuel.

    Is your fuel system stock?
    meh...

    My fuel system consists of factory GA61 lines and Walbro external pump (my car had external from factory).

    "many" = occasionally my ECU when pottering around gets confused and wont come out of deceleration cutout, so you'll be slowing down slowly, go to accelerate again and it hesitates for half a second before jolting and taking off. I didn't notice this before, and both my ECU's do it, so I have to assume it goes into an odd part of the map or something to that effect.

    Hey Pal,can you describe how you adjusted your AFM by 3 notches.

    Sure thing. If you look at the top of your AFM, you'll see the panel which is siliconed on. Use a stanley blade or the like to cut the seal and pry the lid off. Inside you'll see a toothed wheel and a retaining clip. The wheel controls the spring tension.

    Mark where the tooth sits. I used a small dot of nail polish as its quite tough and easy to see against the black wheel. Loosen the retaining clip and try not to let the wheel just spin away. Move it against the direction it wants to turn the amount of teeth you want to tighten it by, I chose 3. Fasten the retaining clip to hold it in place.

    This worked fine for me, and the AFR's are still pig rich afterwards. Do this at your own risk, all Toyota ECU's tend to have their nuances, but given the way Toyota engines fuel on boost, a couple of teeth is unlikely to cause any major lean outs.

    the last pic i put up was of the gen3 ecu 22pin plug plug.


    note; all the labels for each pin were attained by removing the ECU lid and quoting straight off the PCB board.

    When I get home I'll post the 3rd Gen pinout chart I made up when I was going to be doing the 1G swap. AFAIK it lits what pin goes where for most of the plugs.

    I'll put it in this space.

    Sorry it took a couple days to find. All that stuff is on one of those easy to misplace jump drives....

    anyways heres the link to it.
    1GGTE Pinouts (3rd Gen)

    Its done in a .rtf format so most everyone should be able to open it.

    why compromise the image clarity just to be able to see the whole image without scrolling across? they are un-readable enough as it is.


    my computer can handle it fine and its a cheapo computer shop special...im running slow dial up as well

    if its that much of a worry - ill make them links instead of images
