i have a PM6 ecu for sale. it was in my b16 rex when i got it. i ended up getting a pr3 and now i don't even have the crx anymore. it has some sort of chip in it, the tag on the chip reads: '90-'91 Civic/CRX Si/EX 8500 rev limit. J & E Tuning it seemed to run the b16 fine and i am sure it will still run a sohc just fine as well. i will try to get some pics up soon. i don't really know what to ask so i will start at $115. just make me an offer, i need the cash asap. email me at firstname.lastname@example.org or call me @ 731.787.6149 i am in Jackson, TN and will ship anywhere in the US.
