Alright, this is getting irritating... You'd think a 115 HP ZC engine in a 2100 lb civic hatch would be very quick. However it feels relatively fast up until about 3000-3500 RPM then the power just kinda goes away. How is it possible to be able to swap this thing to OBD1 so i can get Hondata for it?? I can barely stand driving it, it feels like driving a geo metro.

It's not gonna be insane but it'll be quicker than a stock civic. Something's wrong if it feels like it's not making power after 3500. My single cam ZC pulls all the way to redline and wants more.

 

Are you getting an ECU codes?

 

nah, no codes... the clutch doesn't feel very good, but that shoudln't have much effect on high RPM power. maybe something like the fuel pump is really worn out, the car body is stock with 220K miles so that wouldn't surprise me. BTW where is the fuel filter located on a 90 hatch SI?

Yeah you need to check that baby out. My DOHC ZC pulls harder after 3500 RPMs all the way up the powerband.

 

When should i shift my dohc zciv been shifting 6g. iv heard 7200

 

and also i am getting codes i think my ecu is from a dx model civic does that make a difference. and how do u find out what the codes are

 

my zc fells stong as hell around 3500,and i shift around 68 to 7k 68k is where it stops makeing power anything after that your just winding it out.what ecu are u useing with the motor?have u done basic mantince on it (cap rotor plugs wires)thing like that?is your check engine light on?if your having power probs cause somethjing isnt right then u need to get it running gooid before going any farther on it cause ull just be wasting time and money prob even mess it up worst then what it is.

 

check your cam timing and ignition timing if there are no codes.

 

yeah i was wondering to bc i have a d16a1 the "usdm zc" and mine is real strong down low will smoke the tires off and everything but up at about 5000-6500 it acts like it wants to fall on its face but i was thinking it was bc i am running the pm6 ecu but would ur cam timing being one tooth off would it still have good power down low? sorry for jacking ur thread

 

bump

 

that sounds exactly like my problem. Mine has the PM6 computer too. changed the fuel filter the other day too and didn't really help out either. that was really annoying because the fuse diagram for underhood was missing so it was really messy because i didn't get to run the fuel through the engine with the pump off. yeah man, this is really annoying i wish i could just switch to OBD1 and use hondata but it looks rather spendy, time consuming and attentive. Ideally for a performance upgrade you can pick 2 out of them 3 but in this situation it's all 3.

 

Tuning that things a waste of money, your going to spend alot of money for VERY small gains

 

how bout tuning it to use 105 E85?

 

i was wondering if the timing being off one tooth would steal give u enough power down low to burn off thr tires and also i was thinking could the two wires for the cam angle sensor could be mixed up

 

that's too elaborate for anyone here to know

 

get an Ebay Mugen chip.

 

dose it smoke black somke.
but it could be your distributor
or get a fuel pressure regulator
and in my 90crx i use a pm8 comp

dont waste your money those chips sucks ***.there just like the spoon chips.

 

chk your distributor make sure it is set in the middle and not advanced
