I'm currently using a pm6 si ecu for my zc swap and i was told by a fellow of honda tech that it's better to use the 91 integ ls/rs ecu which has a 7k redline and that you can get more aggressive fuel map and higher rpms. So if this is correct, I was wondering what's the ecu code of a 91 LS/RS ECU? Thanks.

 

pre-obd pr4

The 88-89 integra ecu is better though..Or better yet the zc ecu

 

i have a 91 pr4 feels good but you will run alot richer

 

in fact i got one for sale if you need one pm me

 

for the dohc zc you'll want the pg7 ecu off of the 88-89 tegs
