I am starting up an ls swap into a vintage car using an LQ4 Gen 3 and 4L80. At this point the wiring harness and PCM has not been chosen.
My 1st question is there any 1MB PCM with cable throttle?
My other question is there any limitations on the older 512 mb PCM that i may not immediately realize:
is far as fuelling calculations capability or deficient operating systems should I even care about getting a 1MB PCM or are they pretty much the same. I would hate to go 512 and then realize it cant handle as much airflow or is harder to tune.
