I have an '87 GT-S, which falls in the 8508-8708 production category. What are the differences, if any, between a GT-S with a 3S-GE engine from 85-87 and one from 87-89? I had figured before that they were identical, but apparently that is not the case!
For one, the replacement 3S-GE ECU from 85-87 is part number 89661-20111, but for 87-89 the part number is 89661-20321. I understand that the ECU code might be improved from one year to the next, but why would the 87-89 ECU not be the one recommended to substitute for 85-87?
