You shouldn't have to reset the ECM after adjusting the timing, but you can give it a shot. Set your timing where ever you want it, with the SPOUT removed. Replace the SPOUT connector when you're finished. To reset the ECM:
1) Disconnect the negative battery cable.
2) Turn on the headlight switch for 10 minutes.
3) Turn the switch off, and reconnect the battery cable.
After resetting the ECM,
1) Start the engine, and allow it to idle for 1 minute.
2) Shut it off, and wait 10 seconds.
3) Start the engine, and turn the headlights on high, and your a/c, with the fan on high, and let it idle for 1 minute.
4) Turn all the accessories off, and turn the engine off, and wait 10 seconds.
5) Start the engine, and make it idle @ 2000 rpm for 1 minute.
6) Shut it off, and wait 10 seconds.
7) Start the engine, and turn the headlights on high, and your a/c, with the fan on high, and make it idle @ 2000 rpm for 1 minute.
8) Turn all the accessories off, and turn the engine off.
This is the best way to relearn the ECM, but you should take a 10 minute test drive afterwards to make sure all is well.
Take care,
