The R34 GTT ECU and TCU are contained in the one unit.
I have had my transmission rebuilt and I'm told it can handle 300rwkw without needing the soft landing, ie timing drop, that the stock ECU does.
I was reading Sydneykid's thread on the SITC and thought perhaps I need a piggyback ECU that goes between the stock ECU and the coils.
Which ones do this? Unichip?
Then I had a brain wave.
What if I get a PFC and plug most of the wires into it so it can run the engine. Then run extensions to the signal wires that the TCU requires to run the auto transmission over to the stock ECU so that both the PFC and the stock ECU will be receiving input from all the sensors.
Any wires that are sending information from the stock ECU to the engine will not be connected. The wires that send information the transmsission would be connected.
What do you all think?
