That's right boys and girls, random misfire in cyc 2 3 4!!! Anyone selling a P28 ECU and a OBD2 to 1 harness, I'm not f-ing around no more

Im going to reset the ECU and try to smile

Etylorcen

Wow that sucks....how are yer plugs?

DeepSi

Damn, sorry to hear.

Damn makes me want to invest in a Hondata before I buy the Greddy kit.

Typical code from the blue box. My idea on this is that the RC injectors don't fit inside the intake manifold hole. The stock one slides all the way into the hole compared to the 310's that only sit on top of the hole. The fuel rail is basically holding the injectors in place. The blue box senses that fuel is escaping past the o-rings. Its so little that you cannot smell or see the leak.
I tried some off the shelf RC 310's and their the same size.

Bottom line is keep on eye on your plugs. They will tell you what's going on inside your engine. I've been getting the same codes but my plugs look great with no residue.
I have a SMC and 450's ready to go. No more codes for me.

Ummmm...... NO
I really don't think the blue box works this way.
(hey prove me wrong)

That's not true, the blue box cannot sense a fuel leak or smell fuel. The rc injectors will seal perfect if installed properly. They don't fit in like Honda injectors, but they do seal. Misfire codes probably aren't related to the blue box at all. There are many things that can cause those codes, many much more probable than the blue box.

FredoSP

Thanks man, Ive heard that before, my plugs look great, I just changed them maybe 500 miles again and they had 2,000 miles on them - yeah im ****!!.
I think its all tied to the blue box, i have no upgrades internally and followed the install (Art + Chris) perfectly. I dunno what else it could be but some people from clubSi have said almost the same thing.

ttt .. anymore ideas?

tony1

Check your compression and valve lash. Either of these out of spec. could cause that light. Also, check dist. cap. and wires, depending on how old they are. I would do the compression test first. A couple low cylinders would cause that. Worn rings, loose valve lash, or bent valves...

FredoSP

thanks Tony1, wires are new, so they are about 2000 miles new, Im going to get a compression test done tomorrow, I'll stop off at pep boys or autozone.

This sucks cause I have to drive back to NY on Sunday and I need a new O2 sensor too, uughhhhhhhhhhh

Arturbo

Tony, I dont think its the compression. He had a healthy motor when I put the kit in for him. But it can be the valve lash since I dont know when the last time he did a valve adjustment.

art

FredoSP

last valve adj was done at the 30K service, but i had like 34K on the motor, think its time, she just turned 57,000 miles today and its a 2000

Arturbo

Its time fred to do your valve adjustment.

FredoSP

YESSS everyone take my money please Forget not having a pot to **** in, i wont even have anything to **** out of, cause i'll have to sell it, hehehe.

I guess when I get back to NY ill take her in to the Dr.

Trac226

That sucks, sorry to hear that bro. I've had great experience with the blue box on my old civic. At 6-8 psi, i had a/f ratios at 12.0-12.5 just for reference.

FredoSP

well what happened? Kaboom??

PM-Performance

i dont know if its the blue box man .
i have the same prob , 1st is was 71m and 74, i screqwed with things and once and a while it comes back now as 71 only .
i think i haev an injector going bad, no performance diff, if anything it feels stronger, but this damn code. i checked everything in the ignition , not it . if it comes back i will swpa the 1st injector with another to see if the code changes cyls

btw, im for the most part back to stock before the turbo install , all i got is my cai , ehaust , walbro 255 hig press, aem ful rail and aem fprmsd dig 6, msd blasster ss, msd cap and msd wires . i think those injectors are getting beat on tough.
i did a compression test after checking out the whole ignition set up and
cyl1-210
cyl2-220
cly3-210
cly4-220
so they all look good.
all these probs started a few days after I had the intake manifold out and layed the rail with the injectos still in it in the engine bay they mighta got banged around and fucked up?

Could it be that using a RRR to up the fuel pressure to those insane amounts [the GReddy kit uses the 12:1, right] cause the injectors to NOT open, thus causing the miss?

FredoSP: Is this happening only under boost or at idle....when/where is it happening?

PM-Performance

i noticed it happened pulling out of some place and pegged it into vtec and there goes the cell , i think thta happened 2 times. the other time my girl had the car when it came on the 1st time .
my plugs looked like **** the 1st time . i had ther vafc tuned for my set up and tthen took off the header and test pipe and didnt think to reset the vafc, i pulled the plugs and they were black like a **** , so i changed em and tyook the vafc out . another time a while ago i had the fpr at like 78 psi or something like that by accident , im sure that didnt help them

Thanks guys, nah the CEL came on under normal driving. Since thw kit was installed I've felt a "hick-up" with the car when I'm driving in 5th in VAC, not under boost at all. I thought I heard detonation 4 nights ago when it was cold, past 7000 RPM, but who knws. I have no other upgrades to the fuel except a Walbro 255lph intank pump and the 310's that came with the greddy kit, and yes they were sodered and so was the connections for the blue box.

I have been having an O2 CEL light, and this is what I thought it was, maybe the O2 caused this problem? Any thoughts guys? I reset the ECU and I'm driving her really nice, no boost for me

b18CT

i had the same prob whit that blue box.1st under the hood you have a fuse box ,disconect the 7.5amp backup fuse so that your computer will reset each time you start your car,some code need up to to 3 cycle to show up(1 cycle =warm up,cool down)
2: regap your plug @32, factory is like 40 and is way to much so misfire will occure
maybe your to rich so raise the boost about 1 or 2 psi max


good luck

I told you to ditch that farking blue box and get an FMU till the hondata is in....
