i've been having a few problems with this danm b16 swap but i'm down to just one left. finally cleared up codes 14 and 41 last night to find out my car runs great. idles fine and pulls to 6k how it should. when it reaches 6k it hesitates like it is hitting a rev limiter then goes up to 8k but not the quickest. any ideas?

oh and before you throw out ideas here is what i have replaced:
converted to obd1 so new...
distributor
ecu
spark plugs
and everything has been timed correctly

 

oh and one thing i thought might be a problem but not sure is that i used a fuel pressure regulator off of a 93 civic which had a single cam. would that maybe cause this?

no will work the same.

what ecu are you using?

 

chipped p28

 

the civic runs off of 36psi fuel pressure. the cx is even 32psi. and all b series run at 40psi. change the fuel pressure regulator, fuel filter and it should be fine. and is your ecu chipped? the rev limiter you hitting might be just a really lean vtec crossover point

 

i bet its the tune you got. im running a stock sohc fpr on my h22 and it still runs fine.

 

the person who chipped it has been doing i for a long time so i doubt he messed up. it's just a stock b16 map

yeah but what fuel presure does the h22 run on

just because he burned you a map doesnt mean its going to be right. try changing the fpr like fmr projects said. if that doesnt work then put a wideband on your car to see what afr its running at when its bogging. gl

 

alright i will try the frp when i get home. so a stock b16 should be 40 psi?

about 45psi. but im still running the one off my sohc. im not saying thats right but it didnt bog.

b series should be 40 psi.

hahaha im having this problem as well!!!! Thats the whole reason I went out and bought a new dizzy in the first place. My car hesitates reallly bad... well it did... i dont know if it will now until i get my ecu from that kid.

I thought mine was the the dizzy cause it was lame and shitty. I was running the stock ls ecu until i could get my p28 chipped, then fried the p28 in the process :-(. anyways, i have a b20vtec setup with the stock del sol fuel pump, stock ls fpr, and vtec is not hooked up yet. also have iridum 4 bocsh plugs ( ), msd plug wires, and a refurbed obd1 gsr dizzy.

yea i thought i had my problem solved last night after i got rid of those 2 codes and it no longer studdered/ hesitated in the lower rpms. now it's just this

I'm not saying I know anything about this but if close to 40 is required and it's sending back at 32 obviously you're light a few lbs at such RPM.

The difference might be in the red line between the H22 and the B16.

I'd check the FPR first .

 

i have had a few idle problems dealing with fpr before. but it always drove fine. but fmrprojects and syndacate may be right. try it and get back to us

 

alright tried the fpr no luck...

 

get another ship and drop it in the ecu. it could be your o2 sensor also might not be switching lean/rich fast enough. hook up a digital oscilloscope and see if it switches fast enough. or not just change the o2.

 

just put in a new o2 sensor when i cleared the code 41. i guess i could try hooking up a wideband

then its the chip bro. where are you from? if you know anyone that can burn you chips, get a itr map. are you sure you have adequate oil in the motor. if theres not enough vtec doesnt engage properly

 

plenty of oil and i'm 99% percent sure it's a good chip.

 

anyone?

 

put a wideband on that ****

 

i guess i could. friend has one. thought of a possible problem... if i was using a d series alternator could this maybe cause the high rpm problems? not sure if they have different out puts?

 

HAVE u ever though of ur vtec kick in and kickng out , happend to me a wile ago , bc my engine was low on oil

 

not low on oil but thanks for the sugestion.
