yo i have a sohc zc, in my 91 dx... i met a guy with a crx sohc zc, he told me he had a p28 ecu out of an 93 ex sohc vtec??? does that work or is he talking out of the ***??? i still beat him..

 

it does work but the engine needs to be running obd1 in order for it to work with the p28.

 

so what did he do to use it???

 

what would i have to do to swith my car to obd1

 

either buy from http://rywire.com/store/ or try to wire up yourself. Check the FAQs on the CRX/EF Civic Forums top of the page.

 

Why would u wanna use the P28 anyway? Just use the right ECU for the motor...

 

well the my boy told me that the rpms go higher than the stock ecu

 

dont believe what they say. research the information yourself. there's plenty of info on this site.

bottom line: that ECU wont work. its a VTEC ecu, yours doesnt have VTEC. so why use it.

 

good lookin on the info... thats all i needed... whats the best ecu for my motor???

 

pm6 or pm7

 

which one is better?? pm6 or 7

 

the pm7 map i used felt alot stronger but i had a hiccup at part throttle, pm7 for power and pm6 for drivability

 

thanks yo....

 

stop saying yo please,

 

I think the PG7 works good too.

PG7 and PM7 are both too rich for the SOHC ZC.

The PM7 is for the DOHC ZC, and uses a little more fuel than the SOHC ZC. The PG7 is for an old school teg motor. D16A1 I believe, I don't really know.

Anyway, it runs even richer than the PM7. It actually hurts power in the SOHC ZC. My A/F guage was pegged rich the entire time I drove with it. normally it bounces. It never moved with a PG7.

Cliffs: SOHC ZC = D16A6 = Use a PM6 ECU.

 

The JDM D15B I have needs a PG7 or a PR4 since it has trouble starting with the PM6. It seems like it needs more fuel so I use an DOHC ECU. I know it runs rich but it runs better for me.

Appendum Cliffs: JDM D15B = Destroked D16Z6 = Use a chipped PM6 (With correct maps) or a P28.

i understand that...But you can run obd1 in a crx, which, i believe was what the fella was referring too....
His buddy said he was running a ZC with a p28...and all i'm saying is that it is possible.

Yeah, so was his motor the VTEC OBD1 version or the OBD0 version?

Man, I noticed that with mostly stock/just bolt ons EF's, it's the tranny that decides the speed. Get the Si tranny. Call it a day.

 

yo two cam thanks so much thats all i wanted, thats it!!! thanks

 

Sorry to bring an old thread up but I thought I would post here since I cant post in the picture thread in which I saw your car.

But...





Is that a whole bunch of ebay c-pillar bars that you bought to make a cage?

 

OMFG , I've seen it all now,
