im puttin a zc swap into my 88 crx si..do i need to get another ECU or anything..someon plz help...

 

Dohc or sohc? obd0 or obd1 ?

 

I'd jump in with the usual search comment, but "zc" won't work on the searches...

If you mean the DOHC OBD-0 engine (which used to be the most common), then no, you don't *need* a new ECU but an ECU from an 88-89 Integra will give you better maps/performance (I might be wrong on the year). Do a google search on the ZC, there are a ton of good articles out there. Here are two to get you started:

Stick with the Si transmission and be sure to replace your clutch or your going to regret it later. Incase it comes up, don't forget that 88 transmissions are differant from everything else.

 

Well...I have 2 ECU's sitting waiting for a new home if you need one. A PM6 and a PM7

 

if you use that 88 trans your probaly gona need a new clutch anyways if you wnana use the flywheel that comes with the zc...
your gona need a clutch from a 84-87 prelude 2.0 si
