Probably the easiest method is to datalog with TunerPro RT, then flash a EPROM for the ECM.  I have had luck de-soldering the 1227747 ECM PROM and soldering in a zif socket. 

In my trucks case I chose to remove the TBI setup and install a TPI setup then use the TPI ECM.  Here is a pic of the conversion I put in my 1994 Chevy truck.  A lot more torque than the TBI setup.

My first fuel injection sway was a TPI and I've always had a soft spot for them.  It just begs to be retrofitted with a Megasquirt unit.  Built a MS several years ago.  Get to learn lots about electronics and fuel injection in general.  Haven't done much with the TunerPro.

It's kinda fun...but it takes me a while to relearn stuff I did a couple months ago :o

I use TunerPro Rt to read, tune and re-flash the 16188051 PCM's for LT1 engines.  You'll need Moats Flash & Burn to flash the EPROMs in the TBI engines.

Have used this free tuning site with real good luck for the LT1 stuff:
