Assuming your using a 92 L67 memcal..
For the software, you can tune on the fly with Tunercat RT Tuner
You would need the license, definition file, and also a way to get a stock bin.
I know the discontinued Moates Ostrich 1.0 will work with the Tunercat program but I'm not 100% that the Ostrich 2.0
will. Just shoot them an email.
It does support your eprom though:
And unless Ryan modded your 92 memcal, you'll need a chip adapter from Moates too.
Beyond that it'* a matter of researching GM, maf only based, programming.
Third gen f-bodies are similar and aside from asking questions, those setups are what I'm learning off of.
I can explain how to adjust fueling and a few other little things but I haven't dipped into spark yet.
(No real point to go nuts tuning since I haven't gotten rid of my idle surge no load problem)
It'* VERY overwhelming and none of the a/f or spark tuning is clear cut.
