I charge the same for all OBD0 / OBD1 'chippable' ECUs...its $75. This is the basic services most everyone gets, includes ZIF socketing (all parts/labor), 2 basemap chips, and return shipping to you via Priority mail.
There are some things not everyone gets...for the full sheet, download this PDF:

You will need to send in this form completed with the ECU.
Let me know if you have any more questions.
