i say who cares i gave my 02 cents and everyone else did if he has ? after this weekend when he get more info. u could do some of these cat things in 5 min like take an infared thema and check the temp before the cat and after or take two of those fish take tem strips and place one before the cat and after and lok at the cat to see if it is a clog.

You gotta be kidding me... cuz no one could possibly be that stupid
I'll keep that in mind when I need to read 80deg F EGTs.

No, there's no head work.

oh sorry but i must be stupid because at my work (oh $hit i am looking at them wright now) also let me make my self clear there are strips that can tell the temp like the ones on a fish take i forgat to make myself clear.

Hey pal, Shut it. Boil knows his stuff.

Also your engrish sucks.

Mr. Maker please lets us know whats going on with the situation. I believe i'm fighting the same problem as you. The power just doesnt seem to be there. Also where have you placed your stock cat? Currently i'm not running any cat, but I still have that pee-shooter stock exhaust. I will be swapping it out this weekend hopefully that will clear up my problem.

ah okay. do they go past 80 degrees tho? that might be important, maybe. Hey boiler, have you thought about getting one of those more expensive code readers that can display fuel trims, correction, and mix? and you're sure there is no leak in the piping?

Code reader is in the works, and yeah, I'm getting one of the ones that reads real time parameters. I just need to get this stuff fixed and working and figure out what thats gonna cost me before I throwing multiple hundreds more. The credit card people are gonna love me this month.

what have you done about the map sensor thing to fool it so it doesn't read boost? missing link?

E-manage boost sensor clamps the voltage on the stock one.

Friday test: VTEC is ON. I just jumped the solenoid, its working fine.

good to hear, keep us updated.

yes the ones at my work read over 80 deg they read up to 2000 deg while in the range of any thing he is tring to find out.
bige19 i think u should shut it ok ......that it for the child play
i no boilermaker know his **** but i was giving an idea that would work.
i read all his thread and learn for his a$s and **** he has gone though and plan for it on my car.i was just giving an idea for him to try.....i just didn't explain what i was talking about.

just 2.5 inch from the down pipe, no cat!

.... and here come the problems....
10 stored codes
Misfire Cyl 1, 2, 3, 4 x2
Random Misfire
Multiple misfire
Fan-****ing-tastic

Car's also leaning out now above 6K. Gonna have to take it back in.

have u even tried to remove the cat?.....

no, its been pouring here all weekend, now that its sunny, I have no place to work cuz no one's home.


I just don't give a **** anymore.

WOW! that sucks. i didnt know ur CEL was even on b4.
ive seen random, mutliple, and 1-4 but ive never seen 1-4 twice.
so when you went through it said p0301-4 twice???? thats odd.

but anyways what do you suspect to be the problem?
of course first thing to mind is fuel especially since its leaning out, but wouldnt they have seen this on the dyno?
let us know how it goes when you get it back!

Strangly enough, I see a lot of people on these boars who use emange and get misfire codes.
Right now I'm starting to think that misfire codes with emange might be just a product flow, where this random code would be just a fluke.
Stock computer will think misfire when in reality its just emanage giving it incorrect readings.
I might be wrong, but this is just a thought.

well with cyl. 1-4 misfire i would think youd feel it. maybe your right, or maybe he didnt notice it.
the code multiple and random, are unimportant its really just reinstating the other 4.

even with one misfire, the car rumbles bad.

I think its an idle or cold start issue. I got one yesterday, and reset the ECU, got the light to go off. It threw one again today after I let the car sit a while. It comes on within a few minutes of starting it, but once its hot, it doesn't seem to do it. My bigger issue at the moment is why its suddenly leaning out.

well that seems to be a tuning problem. You did check engine and cooling system compression to make sure everything is normal right?

so right now youve most likely got too much fuel that low in the rpm, thats one reason that it would have to be warm to not misfire.
whats your fuel setup again?

gear, all cars misfire here and there very slightly, even off the showroom floor. you wont even be able to tell by watching the engine or holding the engine. so unless youve got a terrible misfire/detonation or a consistent misfire/detonation, OR a multiple misfire/detonation you wont even feel it, let alone it wont rumble the car.

well cars that do come from the factory may have a misfire or so but not enought o throw a CEL... but in this case its throwing a CEL so hence in return what gearbox does say is true that with misfire you can tell...


but he did say he reset the ecu so in this case he might have reset the fuel maps (just a hunch)... try reuploading the maps that you tuned with and see if it still does it

I was reading some BMW magazine today and came across one thing. It said that misfire can be cause by mass airflow sensor (MAF) in some modern BMW engine. d17 has mass air preassure (MAP).

Now I'm thinking that misfire can be caused by anything that we try to fool MAP with, e.g. missing link, voltage clamp, TSI black box...etc.

I also do get kind of hesitant engine behavior whet it is cold. Some PORSCHE magasine said that modified 944 turbo have this when ignition timing adavnced/retarted properly...

and how good is your tuner? the thread turboengnr posted a while back about partial throttle tuning made it sound like an all day process that you need to do at all rpm with different maps. if you say all the hardware is installed and working like it should, maybe all this is caused by improper fuel tune.

try atlantic motorsports for tuning. they deal with boosted applications ALL the time. team emotion has a hookup w/ them so they do pretty good work.

Car's going back tomorrow... gonna have the new cat installed and touch up the computer.

According to my timesheet at work.... I'm taking the afternoon off for "a doctor's appointment for an immediate family member".

lol nice

manifold absolute pressure (MAP)

ITS DEFINITELY SUCKING

Holy crap... now I know why I put up with all this ****. Damn it scoots now. Computers touched up, new cat is in and we seemed to have found the issue. It wasn't clogged, but between the twin brick AND the sneaky 1.5" or so donut those ****ers snuck in the back side of the cat, it was corking the whole system.
Only problem is now there's some RPMS where the new one rattles a little bit in the tunnel (the random tech one is a little taller than stock). I need to pick up some of that stick on reflective heat stuff to use as a pad so I don't hear it, and/or get a stiffer hanger for the DP.
But DAMN its quick now.... and sneaky fast, it spools so fast it doesn't feel like it, but its quick enough to get in trouble without much effort.
No, I don't have a dyno number... we street tuned the computer glitch out.... it still pops a little lean (like 12.1 right around 6500) but the e-manage intervals are too big (there's a 10.9 that registers in the same adjustment cell).

awesome man get some vids up at least!
