ok so there is a jdm ecu i can buy...

my issue is i just bought a theft recovered vehicle...
means i dont have an ecu... i can get an oem for about 150 shipped
or my second option is getting a jdm one for about 200 shipped.

usdm one means i have to get the immobilizer reprogrammed along with keys.

jdm one i dont.


is there any other difrences besides the compression being higher in the jdm
ecu and it runs richer?

the code on the ecu is a pcx-J02...is there a diffrence between the pcx-J01?


hopefully i didnt post in the wrong section...lol

 

compression is a characteristic of the engine, not the ecu. but if both usdm and jdm engines are f20c, compression and fuel delivery would be the same, no?

 

right but the ecu commands more fuel for the higher compression engine...

 

check in UTH, you'll have more luck.

 

UTH? sorry im a noob.
