I have a 90-93 MK2 Link ecu with all required parts to run your Miata up for possible sale dependant on interest. Chip is recent and does have option for WBO2.

 

This includes map sensor,knock sensor, and key pad. I do have the ebc(old style solenoid) somewhere but could never get it to work correctly. Everything is in good working order and currently on the car. I am changing emu for extra options is the only reason I am thinking about getting rid of the link. $800 obo

 

Why do you think the EMU is better than the Link??

 

what I meant by emu was engine management unit(link,ms,aem,etc.). Looking at other systems that have more options to control different systems for the car.
