No no. what does the tuner aka madz pcmforless do to the pcm for the amount they charge for this conversion? if it were that easy I wouldn't pay 200 for it. lol

trust me it is that easy, i have done it many times

i think he does a resister mod in the pcm so you dont have to change out your knock sensor

but it is that easy, get another used obd1 pcm, plug it in, change your knock sensor to one from an obd1 car, then just tune the pcm like any other obd1 car

whole conversion with new knock sensor should cost less than $100(used ecm and knock sensor), if you have tunercats so you can tune when done

There's some info on the resistor mod in this thread if you want to go that route.
