nevermind, problem fixed..thanks to ALCT, the inlet gasket was on wrong and was causing a bad idle

vaccum hose is loose and leaking air.. is the card sodered in?

I've checked all hoses, nothings loose....sodered card on? do you mean soder the wires? yes the wires are sodered :(


Here's the rest of the install and the pics
My idle is going up and down from 1k to 2k like crazy. For a while I was throwing cels, number 14 for improper idle...duh, thanks check engine light :roll:

But now, after driving it around a little, no more cels at all, but still a crazy idle from 1k to 2k back and forth. I can't figure it out. I check all my vac lines, etc...I don't get it. Also, the green light on the jrsc power car flashes when the car is running...it's supposed to stay steady. According to jrsc directions, that means my blue wire from the jr power card isn't connected correctly. I've tripled check and it's all wired correctly. eerrrrrrrrr :evil:

So any ideas anyone? I moved the TB around a lot in the engine bay with the cables still attached...any way I could have messed some cables up that way, if so, how to tell?

Well, here are my pics

Placing the blower in place...this install was the worse part...there's two bolts that are pretty much impossible to do, there must be some crazy ass tools I've never seen that can reach to them...on is in the dead center under the blower...freaking crap! I had to use a claw thingy...nomenclature?....to take hold of the bolt, then I used the claw thing since it can bend to manuevar through and under the jrsc and slight the bolt in....then I had to use a crescent wrench with about 2mm of space to move and tighten it down.
the bottom right one, was about as bad...not much room there either. A weird ass wrench that has some crazy bends would have been helpfull...I'm sure JR had some made just for them :roll:
Also, the bypass valve hose was wayyyy toooo small..I've heard of this problem, so I had to go buy another one to reach the install spot
http://a2.cpimg.com/image/FE/B5/32400382-4122-02000180-.jpg
After installing the rest of the components, it's finally done
http://a2.cpimg.com/image/F4/B5/32400372-b944-02000180-.jpg

Now for the ecu wiring

B connector of the ecu. This is where JR wants the three grey wires and on blue wire from the power card spilced into the red, yello, blue, and brown wires of the ecu...they are B2-B5...it says it doesn't matter which one wire you spilce into the other wires :roll: so why make one fucking blue? no idea
http://a4.cpimg.com/image/E2/B4/32400354-3f28-02000180-.jpg

Last one, is for power and ground...very easy, it's A connector. Just splice the red wire from the jr power card to the A2 yellow/black wire. the black wire from the power card is for the black ecu wire A4.
http://a7.cpimg.com/image/21/B6/32400417-2b3d-02000180-.jpg

Then supposedly when you put the iginition to on, the green light in the power card flashes...mine did, so everything is cool.
Then when you start it, the green light is supposed to stay steady...it doesn't, it keeps flashing and it says that there is something wrong with the blue wire connection...I've checked over and over again, still nothing.

So, until I get this flashing light and idling fixed...I'm not too impressed so far. My friend James/LHD_EP3 says it feels much faster, but not too me...but I was like that the first time I drove my jrsc 97 EX...it didn't feel fast until a few days later...weird :?

could it have something to do with your injen CAI? or is it supposed to be able to just run with an aftermarket intake right outta the box?

dunnoz... just throwin out some ideaz, tryin to help...

vacuum hose gets twisted easily (blue soft hose coming out of power card), watch it.
check for odd noises, do you hear a psssssssss ?
like I said, check and make sure the inlet casting gasket is installed properly, look for a leak at the bearings, cover the 20% visible part of the two bearings with your finger and see if idling stops.
I can't think of anything else. must be an air leak. do not drive before fixing the problem :) especially the idle problem.
keep us posted.

awsome...that's exactly what is happening to me. I'm going to have to try that tomorrow, the wife is getting pissy. So now I hope that will fix it, then I need to fix the damn slipping belt prob. But one thing I'm confused when you say the inlet casting, is when you say bearings...sorta confused :confused: But thanks so far man...you're the only one that's helping me :)

yu should have found two gaskets in the box, concentrate on the smaller one. a is inlet casting, stick your head in the engine bay and try to see half visible two bearings (behind the casting). if the gasket is not placed properly the leak is from the bearings. the two long sides of the gasket is different, one side is straight and one side is to seal around the bearings.

Wow I'm totally fuckin' late...damn dude I haven't talked to you in a while and thought you weren't going through w/ the SC. Is it up and running now? I wanna see #'s dammit :D

grats on boost...how's san angelo btw? :)

What's up Alex! :D The sc is running great. only two little problems I had to work out. It's running better and better the more I drive it. I can't get a dyno until I come down to San Antonio...nothing up here :( But I may being hitting the track on May 7th...that's if the baby boy has already come out :D I can't leave Sandra to go to the drag strip. It's running a bit rich, but better rich than lean. I might have some vids up in about a week. I need to get some kind of fire wire connection for this laptop...my other computer went to shit.

Haha whoops missed your thread where you got it all right...that's awesome man. Tell me when you go dyno your car here in SA...I wanna get mine dyno'd too so i'll chip in, maybe w/ some other ppl too...see if we can't get a discounted rate or something? I really wanna see your car tuned w/ some badass numbers ;)

Yea, I don't think your wife would forgive you if you missed your son's birth for some track times lol :D Congrats again

yeap :D it was that damn gasket. Just switch it around...the wider part goes towards those bearings...the round dark grey things

so the gasket just kinda sticks outta the inlet when lookin at it from the front? It seems i have it correct 0_o.

SO like..........the bearings.........should be completely covered by the gasket??

I don't think they are completely covered by the gasket...just make sure that the wides part of the gasket is facing towards the bearings...that will make sure you don't get a vaccum leak

first feel the leak at the bearings (loud hissing), then by using your pointing finger (press hardly) cover the bearings, crazy idling and loud hissing should disappear. thats how I found the problem, it was very obvious that something was wrong in that area. I think JR should update the instructions and put a warning at the gasket install.

Well i dont have crazy hissing sounds and the gasket is indeed in the correct position. Does it matter which way it is on tho? Like which face should be against the inlet? didn't look like it did. my idle is not freaky. It seems normal. Stays just below 1k tho. That might indicate something..

What was your crazy idle situation like?

it was idling back and forth between 1000-4000 rpm. every 3 secs. oh what a bitch it was.... what exactly is the problem you are having? crazy idling or an air leak?

well..my idle seems just fine. The car feels great!

My problem is that the yellow light (middle) one on the a-card never goes off.

i don't hear any hissing from the engine.

My other problem is the tensioner. My belt does not seem to be able to tighten. The tensioner bolt is all the way down. The belt even slipped off.

I dunno whats going on? the only thing I can think of is that i got the wrong belt from jackson but 02SilverSiHB said that i have the right one.

im all trippin.

Another weird thing i noticed is that when under boost, the a-card makes a buzzing sound. Is that normal>?

when installing the belt, start from bottom of the crank pulley to ac compressor to water pump to alternator to SC, from the sc goes under the tensioner pulley and finally back to the crank pulley.
as for the yellow light: did you cut and solder the wires or did you use t taps? I called JR with the same problem and they advised me to solder. problem was gone. Buzzing is prolly from the yellow light being on. did you reset the ecu?

what size pulley are you using on the jrsc? is it a 4" or 4.4"

ALCT: Im made a diagram of how i set up the belt. (as seen on kseries)

http://www.astralaxe.com/belts.jpg

I did not solder the wires :/. I suppose i should do that.

It's weird tho...the "buzzing" only happens when the boost light comes on. I'm going to call them on Tuesday.

02SilverSiHB: using the pulley that comes with the blower. I measured it and its about 4 and 1/4"

the pulley will say the size on it... on the side of it closest to the charger...but it should be the 4.4 since it came with the kit. I'm not sure why you're having problems.. Also, k20bucket had the yellow light but got it fixed...ask him about it.

hhhmm, strange, on the side of the jackson racing pulley, the side without the nut it should say 4.4 JR pulley...mine does, also the jrsc from the rsx says 4.0" on it...weird, you might have a small one..so if it's closer to being 4" then you have the wrong one...

Anyway, it's k20nutbucket I was talking about, on this page he says he solved the problem...might check with him on that yellow flash
http://www.ephatch.com/forum/showthread.php?t=40306&page=3


By the way are you sure you have the black tensioner pulley tightened? and it's not sitting at an angle..if it's sitting at an angle it will make the belt slip off.

iR-VTEC2
07-06-2004, 10:09 PM
yep , the tension is seated well and straight.

I tried calling jr today but i guess they're busy. Holiday weekend and all
I sent them a detailed message as well and made sure that i put that im asking people on ephatch.com as well as k-series.com about this problem

Im gonna continue to try to call oscar.

sigh. nuts trips man, nuts trips.

hey i just installed my jrsc this week....i went with the short ram intake because ive read on my research that the more the blower has to pull to get air...the more power you lose...so the shorter the intake, the less it has to pull for air...check out the pics
