Set timing on a 82 and now computer bad?

This is the first time I checked the timing on my 82 so it's a new experience for me. Anyway after disconnecting the EST I knew I would get a check engine light, no big deal. But now after reconnecting the EST and clearing the computer I still have the CEL on. My code is a 34 which is a map sensor. I have the factory manual and after following the instruction as far as jumping different pins it says if you still get a 34 then replace the ECM. WTF happened?? If by jumping the pins on the map sensor leads you to a code 33 then replace the map sensor. Well last year I replaced both and fortunately the ECM is still under warranty. My question is why would disconnecting the EST screw something up in the computer? I still thought about replacing the map sensor again just to be safe. What are your thoughts??

I doubt it had anything to do with setting the timing and more to do with the same voltage spike that burnt out your timing light bulb.

Computer is fine, for some reason it took out the MAP sensor.

try resetting it again, sometimes just resetting them kicks a code, doesnt mean you have bad parts, just indicates a brain f$%rt, warm it up first.

Glad you got squared away, and that it is running good. I have yet to check the timing on mine, as it is also running good, and I just haven't allotted the time to do so......I still haven't put in the Hypertech chip I got last year.
