i just swapped in a 94 jdm b18c into my 93 civic ex...before the swap, i had a first gen b16a with a chipped p28 ecu...the ecu had the program with the knock sensor disabled...

1. would my b18c run fine if i hooked it up exactly like the b16a?? thats what I did and my car stutters, surges during accleration, and idles like crap....also, i have a cel but i dont know the code...

2. I should be recieving a 95 GSR ecu shortly...would this remedy my problems...or is this a vacume or wrong connnection problem...

any suggestions?? or did i really screw this up??

Well if its coming in why run the risk of damageing your b18. Patience is a virtue

I thought that it should run the same.....or am i wrong...

will the gsr ecu totally remedy my problems???

fowler!

Check the code. That will answer a lot of questions. You may have missed a sensor when you put it back in. Most likely, not the ecu.

It sounds like it could be a MAP sensor problem. Honda motors run like **** if the MAP sensor is messed up. When we installed a Skunk2 Manifold on my friends LS, we put it all back together but got the plugs switched for the MAP and TPS. Needless to say, we "tried" to take it for a test drive but the car drove so poorly (stuttering, no throttle response, etc..) that we had to bring it back because of that problem. You might have done the same thing (switched the plugs). The plugs are identical, so you have to make sure you have the plugs with the right color wires going to the right sensor.

could possibly the wrong vacume setup create all these problems???

and i forgot to mention that my car was running really rich lots and lots of black smoke....could this be the ecu??

there was still power through the gears, but at some instances, it seems like it was surging...rough idle....

i checked the map sensor, and i dont think i could have messed up those wires, because there is no way for the TPS to get to the map sensor, the wires are too short...

any other possibilities??

smnowell

Did you check what code the ECU gave you? That could be a start to tracing down your problems...

degooser

do i need to tap into a wire to find out the code...i cant seem to find the ecu led on my ecu?

chipped p28...

fowler!

there is no led on obd1-2 ecus.

There is no AIB Valve on a b16, and that will make your gsr a turd if not hooked up properly. so once you get the gsr ecu. look for a ecu pin out if you dont have the gsr complete harness you need to pin wires

degooser

i got seven blinks...i dont think that they were long so i think the code is 7

Not necessarily, I ran a Skunk2 ecu meant for a single runner IM on my stock GSR. I had no problems at all. Everything ran fine and I was quite pleased. There was a little idle surge, but that's about it.

fowler!

7 is your TPS. Check the connection.

cnydelSolHybrid

yes it will, you eliminated the problem. the 2 stage intake manifold. it wont function properly unless the aib is wired to the ecu.

Now you eliminated the problem totaly. but he has the aib valve. its not wired and its messin **** up.

cnydelSolHybrid

And mabey thats not the problem he is having yet, but if its not pinned to the ecu its not going to run right. I just got the skunk2 IM that gsr **** is the biggest POS ever.

my friends b18c1 is doing the exact same thing; he's spitting out a considerable amount of black smoke when on WOT, and it randomly stutters as well, but the CEL isn't on. We've been trying to figure this **** out for a while now. I thought he might have an 02 sensor going bad, which would explain his sucky fuel mileage and running rich like he is, but we just don't know. I wish we could figure this out; Acura was a COMPLETE waste of time. They hadn't a clue what was up.

fowler!

No, this was on a stock gsr motor. Still had dual runner intake manifold.

cnydelSolHybrid

You can ask anyone with knoledge of aib and what it does. if you did not have it wired and its on the manifold its going to mees up the air flow. Its a Fact. argue all you want but your engine was not function properly if its not wired and its there.

I know this from experience. i was happy with my swap till they told me what i had missed. and once i fixed it it was a whole different beast. like it or not

fowler!

What, so my experience with a motor that ran a singler runner ecu for over a year is invalid?

degooser

well i checked my connection on that sensor, and i still got a cel and my car still idles like crap...any other considerations....

i am hoping that a p72 ecu will cure my problems....

anyone think otherwise?

degooser

whats your friends set up for that motor...maybe we have the same problem??

Hybrid Invasion

b18c1 with i/h/e. We wired everything, then checked, doublechecked, triplechecked, then this. When it idles, it sounds ok for a little while, then sounds like someone threw marbles into the header and it's spitting them out(lol thats the only way i can describe it), then it returns to regular idle. No idle surge or anything, just very inconsistent. I wish I could be of more help other than just saying he has the same problem and we still haven't pinpointed it. As soon as mr. cheapskate decides to buy a new o2 sensor, we'll see if that was it or not, so at least there's one less thing that it could be.

Hybrid Invasion

funny thing too; he was running a 1st gen b16 in HIS civic too before we did this swap, and the b16 ran absolutely flawless.... ECU wasn't chipped though; we ran the knock sensor wire after we threw the GSR motor in.

7 is your TPS. Check the connection

i checked checked and checked again.....i also took a TPS that was working before and tired it with no luck......

what could it be??

will this sensor cause your car to idle harshly if it is throwing a code??

anyone have had this code on their car???

degooser

my car is not in limp mode either...just running real rich...

could this be the o2 sensor also???
