Hello, early JDM ECU question

[RHDGvr4]

My car didn't have a ecu when I got it, it is supposed to be a group n box, bought it 20 years ago,

I haven't played with the dual boards up close, but you do have an Eprom chip with the red label. Hopefully that is the chip we are all swapping out for Link/ECMLink.

The coding between the single and dual board ECUs is vastly different. I dont believe you will be able to run ECMLink in your dual board ECU unfortunately.

How about a halltech?

You can use a later model single board JDM ECU with ECMLink with no issue, per this thread:

I'll have to compare it to the us model gvr4 eprom. I thought I read somewhere dsmlink didn't work for dual board early ecu's. This one is socketed, would be cool if it did.
