JRSC Problem...

Update: I just installed a boost gauge because i thought that it would give me some idea as of what is happening. I installed it and it is constantly reading at vacuum no matter what rpm its at. So obviously something is wrong if its not creating any pressure.
I am assuming that means I have a leak somewhere. Is that right?

Ok, I talked to my tuner. He said that the part that he took out that made everything work smooth again was the vacuum stabilizer. It's a really small part that blocked one of the hoses. Once he took it out, the engine revved smoother like it was supposed to.

by pass valve stuck open all times?

btw: did you tried the car with the boost before the problem began? was it good?

Huh. Well I talked to someone from jackson racing and he said that he thought that i might have not reconnected one of the grounds well enough and it fried my ECU which is why I am throwing all these codes. That sound reasonable?
Where is the vacuum stabilizer located?

Yeah I was wondering about the bypass valve, but i looked at it and it doesnt seem to be stuck open. And I didnt have the gauge to install until after the problems began, so i dont know if the gauge not reading any boost has anything to do with the car dying.

I'm not quite too sure where it's located. Why don't you go to a tuner and have them check it out for you?

Update:
I took it to the tuner and they figured out what was wrong....it was a badly connected butt connecter that was causing the ECU to short out.
Well at least it was an easy fix...haha
They also fixed the Crank Speed Fluctuation Sensor and replaced the Knock Sensor, so I am not throwing any codes. YAY!
They said I installed everything else correctly, so I should be good to go.

Please tell me you have some sort of tuning program in the ecu. THats #1 in my book whenever you start modding. If you dont then I highly sugest getting the hondata s300 set up and gettina profesional to tune it on a dyno.

I dont want to sound like A jerk or anything but I would never add a super charger or turbo without the propper way to tune the car. Now I run nitrous and you can get away for a while without tuning but I believe its way important w/a turbo or SC. Please be very careful with your car bro. I hate to see a perfectly good honda motor blown up just from the lack of $700 or so bucks. My buddy sells s300 for around $600 and dyno tunes for just a little more. Be cautious of who works on your tuning. Mad props for installing the SC yourself.

Just wait till he gets a ECU and tune. Wot all the time, lol

I've installed two JRSC's with my buddies. In their front yard =)
One in an EP3 and another in DC5-type S
