In the 91-94 ECU we would need to replace the 2nd data chip with a socket and a new chip that has its own COM port or something that would allow for data read and write, hopefully real time data changes and not a single flash type chip.


I assume the 91-94 are single layer boards and should be easy to install a socket to hold the new chip.


Will these modifications fit inside the OEM ECU housing or will that need to be modified?


What are the estimated hardware changes going to cost? Your best guess.
