I just got a DOHC ZC engine and i was wondering if i get the integra ecu if the engine will run better. I heard from someone that i should do this. Also do i need a new header for the engine, or will my stock DX header fit on it.

 

DX header will fit, but wont line up the ports exactly as intended. but it will bolt on.

use a 88-89 pg7 ecu.. the 87 and earlier use vacuum advance (u dont want that)

 

crx is right. pg7. make sure its out of a 5 speed and not auto though. this is coming out of an integra. I've seen them for sale on here for anywhere between 50 and 100 bucks. But most often in the 50-70 range. Check the classifieds here or seeing as you're new and i dont think you can...check out http://www.thezcr.com and go to their classifieds. there's almost always one for sale. there's some posts on here that explain exactly what the differences will be. Its something like more aggresive fuel maps and higher revs. I have the sohc zc so this isnt really my field.

 

I have a PM7 left over for sale.
Those are the EDM ecu's we have stock on our D16's. (1.6i-16V DOHC)
It's meant for that engine, so you can't beat that.
