Is it possible to change the control program of the hitachi engine block to nissan?

Question

Electronics

There are two programs: one for the 2008 cvt stepless automatic transmission (CVT) and the other for the 2007 4-speed automatic transmission.
instead of automatic transmission cvt I want to install automatic transmission 4-speed. both programs work on the can bus. ecu nissan hitachi
Is it possible to change the program?

Answer 1

And exactly does the ECU under the control of the variator have those outputs for controlling the torque converter control solenoids?
(simplified: it is not a fact that after flashing the washing machine with the refrigerator firmware, it will be able to cool the beer)
therefore, you will probably have to give up not only the boxes, but also the ECU

Answer 2

all blocks work on the CAN bus (two wires) engine ecu, automatic transmission ecu and all other blocks, even the fuse box! Naturally, I will change the automatic transmission control unit, I need the engine ecu to be friends with the new automatic transmission unit and not turn on emergency mode. there is a firmware for automatic transmission and there is a firmware for cvt (variator). you need to transfer something from one to another!
