ok i have a 3rd gen shell i just got a jdm motor for the harness is a little jacked up i was also given a jdm computer so what should i do here? buy a new jdm harness? what has to be modified to make it work? or should i buy a us harness and will it work with my jdm computer or will i need a us spec computer????please help

 

Get a rywire instead of messing with used harnesses you cant get them set up to whatever u want to run

 

Also, maybe I'm mistaking (if that's the case, someone trustful correct me), the jdm computers are made for slightly higher octane gas (super plus 100 octane). This means that if used with 91 octane in USA/Canada you would be more prone to detonation.

Personally, I use a PFC, so it's not a concern for me, but for jdm computers what's the deal?

Please someone enlighten me?

 

If i'm not mistaking the JDM harness wouldn't have an EGR valve either. I think they have different specs for emissions. I would also consider the RHD versus LHD hassle for wire lengths possibly. I agree with hyphyone510. Just buy a new harness.

 

Apparently the ECUs are exactly the same between the JDM and USDM cars. There is some difference between how octane content is rated in Japan. I asked this question recently because I am importing a JDM Rx7 and wanted to know if I needed to replace the ECU. Here's the thread:
