...run like ****? I mean seriously... i want a perspective from people that have owned both obd0 and obd1 EFs. Is OBD1 the way to go for mileage and driveability?

I've never really driven and OBD0 bswapped car that truely ran smoothly, yet obd1 gs-r swaps feel like butter through the wheel, pedals and other various sensory inputs. Maybe my motor is just horseshit and in need of replacement.

Feel free to pwn me if this has been covered before... but i searched to no avail.

 

if ur engine is runnin well and there is no prob with the ecu, it should run great.

mine never did though, but that was a bad motor on my part

 

I'm just about to junk the OBD0 and the B16 all in one swift blow... [freak] it. The only thing really wrong with my motor is LMAs... which unless dislodged won't really cause a problem. Valves are all adjusted.... no real leaks... good vacuum.... no codes.... good compression test results.... hmmm.

Also i've heard something along the lines that OBD1 samples data faster for fuel trim..... true?

You shouldnt be able to even tell the difference.

Whats the big deal? What is it doing thats pissing you off?

My OBD0 B16A rex runs like a new car.

 

Did you tune the OBD-0 engine? I've tuned OBD-0 (using BRE) and OBD-1 (using Crome Pro, hondata, etc.), there's really no difference in drivability especially on stock to meduim builds.

 

I can't seem to get the damned thing to idle right. Iacv is clean... fitv valve is tightened down... no vacuum leaks.

It seems like its using alot more fuel then it used to (24mpg down from 28-30) and it sputters ALOT when i'm in gear and closed throttle ( not missing, just a good amount of pops and backfires while delecerating ). I'm running a bone stock ECU so I know thats not it... sigh

Edit: The motor is also bone stock as it sits now.

 

Change your O2 sensors for new ones. Run the 02's in the correct location no matter what header you use, have them welded in the correct location.

Change your thermostat.

Do a tune up, adjust your valves, all of these things create problems.

I had an idle issue that I couldnt figure out for the life of me. It ended up being a thermostat that was not operating correctly.

 

[freak]en a.

well.. would an o2 sensor trip a code or no?

and which o2s do you get for a single wire sensor? like what make and year would you get it off?

i feel like a newb askin **** like this

 

The 02's being unused or in the wrong spot wont throw a code, mine didnt anyway, but I only had them in the wrong spots.....

But universal single wire 02's from vauto zone, they work just fine and they are only 20 bux a piece. just splice them in or cut off and reuse the old plugs.

All O2's are the same size and thread, just get em for a 88-91 CRX

well i'm off to autozone to get 2 o2 sensors and a thermostat.... at least my cars getting alot of new parts out of it lol

 

with some luck and fiddling obd0 can run ok.

Where's the poll link for you're a dream boat.

Saturday night.....lulz

THreadJaK.......sorry kip....let us know what happens

 

hahaa come on... the ambient convo between you two is MUCH more exciting then my shitty sedan lol... i'll have the o2s on on saturday... so i'll be back....

 

i'm curious how you make out...my car runs ok most of the time, but i'm guessing i could use new o2 sensors too. my mpg is 25-30 but usually on the low side

 

the o2 need to be in the right spots, but if you go obd1 It will run like you said Butter I was obdo for the longest time with my b16, its never idled as smoothly as when I switched to obd1, now I also get 30+mpg highway even running a jrsc at 8psi

 

thanks for the input jimmy thats precisely what i thought.... i've found more and more that obd1 seems to be the way to go... but i'm still gonna go spend the $60 on two o2 sensors just to see if it gets it back in the realm of being correct.

 

My B16 in my Rex is running pretty good right now with OBD0 and it doesn't sputter or have any issues but I plan on swapping to OBD1 for sake of tuning purposes.

 

Im telling you man, after I changed the O2's and the thermostat, It runs just as good as any other honda on the road.....reguardless of on board diagnostic year.

 

oh yea... i'm still doing that. but within the next half a year or so i will make the jump over to obd1 as said... for tuning purposes.

 

Me too....I would like to get into data logging and tuning my own shtuff....ya hear?

 

For some reason after revving my car, the rpms drop to 0. and sometiimes the car stalls, and sometimes it goes back to 750.

Then sometimes it keeps going up and down 500-750

You should look up EFI University... next time they have a class near me I want to attend.

Have you checked for proper operation of your FITV valve?

Look at yours.... if its not the cause of the problem its probably a contributing factor.. they seem to come loose alot.
