byrans fix for obd1 stall

his fix for the obd1 and high stall, is it in the tunning or the pcm itself, like to you have to send him the pcm because he has to fix hardware or is it just a tuning issue. if its a tunning issue why cant i just get a tune with the stall fix and and my tuning to it.

does anybidy no what the fix specificly

one of the fixes has been covered here quite a few times recently...so a search and you'll find it in this forum, or in a long thread in advanced tech

well i found out what it is. i was almost done figuring it out but needed alittle help. and i got it from someone that knows. and it does worked solved our problems. that 3500 stall shift perfect now. and not so bad on daily driving now either.
