hey guys just wondering if it is possible to use
a jdm ecu on a usdm car

 

Yes and NO i'll explain the OBD1 simple answer:yes so long as it's meant to go with your enginem so no using a p75 for your GSR(b18c) However all that goes out the window when it's chipped or has a s300 I have a jdm P30 with a s300 for my b20V. someone else can confirm the difference with obd2 and it not looking for certain things.

 

Yes

 

yes. obd2 will not work for those who have obd plug in testing.

 

so on obd 2 the code tester is the only thing that dosnt work?

 

yes, that is correct.

 

Cool tanks for the info everyone

 

A JDM ECU will work fine, and wont look for a lot of sensors USDM OBD2 looks for (CKF, secondary O2, FTP). However as stated it wont communicate with a scan tool, if you live in a state with emissions testing just keep in mind this also means the car wont pass emissions with the JDM ECU.

 

Perfect answer/explanation of the OBD2 versions !, wasn't sure what it would and wouldn't detect a lot simpler with OBD1.

 

I hope you dont live in California
