please help ecu trouble??

[mikiebabie]

i have a 91 civic hatch si and have a 2nd gen zc
with three different ecus to choose from
i have a pm6
a pr5
and an 89 integra ecu

the thing is my pr5 is automatic,
i was talking to someone today and they said there was a way to convert it to manual
i like the 89 teg ecu but one minute the rev limit is 7000 and the next minute its 7800 even if its warmed up all the way does anyone have a suggestions
and the pm6 just sucks

thanx in advance
