Full Version: 1zz-fe ECU
just wondering, is the mr-s and rolla 1zz-fe motor car ecu the same?
Well it would be hard to say yes 100% but no doesnt quite cut it either
In essence the engines are the same but the mr-s ecu revs higher and has a few wires that are in different places to the corolla model such as the temperature gauge and the radiator are 2 things that i have seen that are different.
So i guess if you can find where those 2 wires are in the mr-s ecu and in the corolla then you can swap the ecus over but i couldnt tell you if it would work properly unless someone has done it
The power fc replacement ecu that we have available is made for the mr-s and i guess that shows the aftermarket ones work with our cars but id leave it up to the experts of the forum to answer if the stock mr-s and the corolla ecu are close enough to swap ecu's and sill work properly
I hope this helps u in some way!!!
if i made any sense well it is 12:30am and im tired ill see if i made sense in the morning hehe
