How Many Computers In 2jzge Vvti

[Speednik]

Hi Everyone;

I am new to this board, and was wondering if any one has taken out there engine(2JZGE VVTI) out of there car? If so How many computers control the engine. I want to make sure I take everything out that is needed. Also How many computers control the Auto/Tiptronic transmission?

Thanks in advance. :D

for things like

engine(and gearbox if auto)

power windows

moonroof

alarm and security features

aircon and radio features

I am in agreement. It seems you want to know how many control the engine and tranny alone? That should be one for both. Under the passenger side carpet. A factory service manual will tell you definitely. There is also an ecu for the fuel pump.
