i have a 93 Na hatch. It has a p72 ecu that is socket-ed. Im looking to buy neptune or hondata s300. do i have to pay someone to solder on board. is it plug in play. sorry for dumb question. i dont know its my first honda

 

If your ecu is already socketed, neptune doesn't require the removal of the socket.
It does require a 4 pin header at cn2 on the ecu.

If you plan on running hondata you need to remove the socket & 4 pin header which end up being replaced by male pins.

I would suggest you have the system installed for you.
