greddy profec b spec 2 problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Mr.s13r · 11-23-2008, 01:40 AM

I have an s13 sr with t25. Here is the problem, i just got this ebc and pretty sure i install it right. Fpr goes to the back of the unit then the hose from the actuator goes to COM on the sender and a port from NO goes to the hotpipe. Correct me if I'm wrong on the installation. Well i drove couple of days with the ebc not turn on (didn't connect the power plug), getting almost 9psi. So today, i got everything done and turn on the boost controller and it doesn't even seem to work. I set the SET to like 0 or 100 % and it still boosting at 9psi. Also try to mess with gain and set gain but still nothing changed. What did i do wrong? Please help me out.

corey240 · 11-23-2008, 11:36 AM

Fix your english. Go to Greddy's website and download the good manual. If you dont know how to use it, I HIGHLY suggest you unhook it. I promise you will blow your motor. 100% gain? Turn everything back to 0. Read the manual. Set it right. Or get it tuned by a shop or local that knows how to use it.

Mr.s13r · 11-23-2008, 12:49 PM

Sorry for the english lol it was like 4am when i wrote it. Well like i told you in the 1st post even if i set the SET to 100%, the boost still won't change. I've already download the manual when i tried to set this unit up but even though i change a setting, the boost still won't change. Lmk what you think?

slider2828 · 11-23-2008, 01:19 PM

Hooked up wrong or broken.... It simple.... take pictures of your setup...

Mr.s13r · 11-23-2008, 03:41 PM

cool try to upload it tonight if it can still snap a pic after work.

corey240 · 11-23-2008, 05:12 PM

Yea it sounds like its either hooke up wrong, I would assume mechanically (vaccum lines). Or broke.

Mr.s13r · 11-23-2008, 07:05 PM

here is the picture, with the NC port covered. Also try to see if the actuator is shot or not by taking the hose to the actuator off and running it like that. It ran above 9 lbs just like that. Well i guess the valve unit is broken =(

SoguRacing · 11-23-2008, 07:56 PM

did you look up the directions to on the greddy website?

Mr.s13r · 11-23-2008, 07:56 PM

Yea i downloaded the manual. Try to set everything but still didn't work

slider2828 · 11-23-2008, 08:10 PM

How about the other module.... The reference boost part that gets a vacuum from the intake manifold t-ed off with the vacuum used for the air fuel pressure regulator....

wtf...

MetricHotrods.com · 11-23-2008, 09:46 PM

you guys are tards.

original poster..take the fucking plastic plug out of the side of the solenoid. the lil clear cup shaped thing.

vroom vroom huh..

sorry, i thought the point of a forum was to ask and answer questions, not to tell someone the answer of their question is in "the manual"

if you dont know the answer and the only thing yo ucan add is "read the instructions" then why post at all?

Lol you damn right about "the manual." Yea i don't have any clear plastic thing. If you are talking about the NC port which is the only port left out of the three then i plugged that up with tissue and tape it with electric tape. Lmk thanks

Did you look at the question I asked above?

Mr.s13r · 11-24-2008, 04:50 PM

Oh for that i T'ed off of the fpr then also t'ed off again for boost gauge. lmk thanks

MetricHotrods.com · 11-24-2008, 05:14 PM

again, UPLUG THE 3RD EMPTY PORT IT NEEDS TO BE OPEN THAT IS YOUR PROBLEM. take the toilet paper and tape out of it!!!

and set your boost and gain at something like 60% and 8% gain because when you take that little ball of shit out of your solenoid, its going to actually work

have fun.

MetricHotrods.com · 11-24-2008, 05:16 PM

i dont know why everyone plugs that 3rd hole, but this question comes up about every 7 days on all the skyline forums.

You sir crack me up. I was in a bad mood and you lightened it right there.

Mr.s13r · 11-25-2008, 12:48 AM

Well i tried setting the boost and gain with the port uncovered before and still had the same problem so i thought it needed to be covered that why i covered it. But ill try it again then let you know.

Mr.s13r · 11-26-2008, 09:46 PM

Ok it still does the same thing. Lmk what should i try now?

slider2828 · 11-27-2008, 12:59 PM

Are you sure everything is plugged in? Check your wires running from the Solenoid fpr continuity. Meaning no shorts....

toycar · 11-27-2008, 03:05 PM

did u plug the solenoid into the unit? did u push enter everytime u set ur boost? do u have an aftermarket wastegate? if u did hook everything up right then theres no way u could be turning it up and down and see no change.

SoguRacing · 11-27-2008, 03:09 PM

well if all else fails a have a brand new greddy solenoid for sale.

slider2828 · 11-27-2008, 03:17 PM

Hahah nice sogu...

I am pretty sure everything is plugged in right. Sorry but you have to guide me to check for the Solenoid fpr continuity. Well if i look at the Profec lcd screen it shows about 240 something at idle and when i step on throttle it goes up to like 300 and up. I don't know if you can tell something from that?

P.S - i put mine into psi.

I did push the set button in to set the boost. I don't have an aftermarket wastegate i run it to the actuator, the COM port. My friend have the same profec on his MR2 so i asked him to use the solenoid but when i put his in, the boost would go up all the way even if i set it to 0% boost. So iono what's going on right now.

How much are you selling it to 30093?

slider2828 · 11-27-2008, 04:46 PM

For continuity...> basicallyget a volt meter and from the plug in the engine bay see if one side of the plug to the other side of the plug in the cabin beeps to see if it is clear...

Dude did you read the troubleshooting thing at the end of the manual? Did you do those tests?!!!

toycar · 11-27-2008, 04:51 PM

did u buy the thing used??? it sounds like your solenoid is seized if your frends one works and not urs?

Mr.s13r · 11-27-2008, 05:13 PM

Yea i read the troubleshooting and check them already but still has that problem. Yea i bought a used one and even i put my friend's solenoid in it just boost up to like 15 even if i set the boost to 0%.

Mr.s13r · 11-27-2008, 05:15 PM

Also as i posted in earlier post, why is my idle on the profec lcd read about 22-25 lb which is like 220-240 on the lcd. Shouldn't it be something in the -90 or something?

slider2828 · 11-27-2008, 05:54 PM

It should read like -22 PSI or something like that... Did you are idle fine before this? When you remove the whole system does it drive fine?

Mr.s13r · 11-28-2008, 01:27 AM

Well it drives fine even with the system connected. The only thing happen is that i can't set my boost no matter what. Also, my idle has always displayed like that ever since i hook up the unit.
