Hi im looking for a pinout for my 1994 r33 rb20e (auto) tcm. This is the computer that's by the drivers kick panel. ( by the gas pedal)

I have looked everywhere and can't seem to find it.

What I'm really after is I want to know where the wires from the ecu (engine) sends the signals and what signals they are to the tcm.

I have the diagram for the ecu but there are some wires that just has an arrow going to "a/t control". Well that's all it says.

I have just done an rd28 to a rb20e swap in my 1994 laurel, it was a lot of work but the car runs, but I notice the shifting is only at around 3800 rpms. In short it only shifts by rpms. And if I let up it just won't shift up at all I have to get to 3800 rpms. This is using the rd28 wiring loom with the rb20e tcm. Also if I just go in the gas hard the car stops making power until I let up just a little. I have a feeling that the tcm needs these signals from the ecu along with the electronic kick down signal from the tps.

If i was to get the diagram I'm sure i would be able to figure it out.

Thanks

I just down loaded the manual. But I can seem to find the pinout. I see that they are saying that some of these wires from the ecu goes to dt1 and dt2. This has to be my problem. Im so close.

Help please.

    • Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!
    • Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that 
    • Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
