Tune moved to late model computer I have a 1994 LT1 which has a tune that I like already. I'd like to consider moving to a later model computer and getting rid of the Optispark using the later model PCM and sensors. Is it possible to copy the tables from the OBD1 pcm to a late Model PCM or do I need a new tune altogether. I'm happy with the performance of the current tune and simply want to match that with the updated system. As you can see I don't know much about tunes.
Thanks,

I think some of the map and rpm boundaries in the VE tables are different between the two PCMs. You may can do some interpolation to get some values, but I think dyno tuning a new table for it would be best.
