if i put a 2W ecu on a 4WS car will i loose 4WS ?

 

I believe so.

Actually - thats a good question. Since the steering parts are mechanical.

 

So far i know that you can put a 4w ecu on a non 4ws. so i think you can, it might not change much

 

.....i th ink he means putting a 2ws onto a 4ws.......

Will the 4ws still work?

 

the box that controls the 4ws is seperate and is in the trunk bolted to the back of the passanger back support.. looks like a big amp

the ecu in the front of the car is seperate from the ecu that controls the 4ws.. hence there is no such thing as an ecu that is for a 2ws or 4ws. you need a h23 ecu. done
