Re: need help urget! (themachasy)

i dont think its limp, i loosend the nuts bolt on the wastegate (like cranking the turbo). still same thing. i know how limp mode is and how it feels once i hit it. but to me its almmost same but then not limp mode. no boost over than 2 psi. oh yeah i just have diode no boost control. i had my turbo cranked bit but now its in the stock.

What is "turbo cranked"?
Have you checked all your connecting hoses? Have you scanned for codes? I would imaging if the wastegate "failed", you would have continual boost. Is your DV stuck open? What else have you done?

i hear my dv hissss, all the hoses right where they belong. i got it scanned today at autozone. i had 20 codes, mostly ho2 sensor cause my downpipe, and low electric curcuit.

Just a diode and no boost control is really bad, you're basically spinning the turbo as fast as it'll go after your diode starts "working" if you will. I'm not sure you broke the wastegate, I haven't really heard of that. Wow 20 codes? What codes? Thats a lot more than a rear o2 because of no cat.
Like.. with the diode do you realize your car will boost whatever the turbo can, and you really should have some form of boost control to prevent blowing up the turbo or some other nasty issues?

Re: need help urget! (themachasy)

you might have broke something or atleast you will if you keep going with no boost control. you need to get a manual boost controller to stop from over boosting. the ecm goes into limp mode after it sees boost around 23psi or so to protect the engine. a new k03s is relatively cheap to replace but you've got a lot of things going on here.

The ecu can't see 23psi, its got a diode. List the 20 codes.

Yep, 11 PSSI is all the ecm will see, and the turbo is junk now.
Diode with no boost control is suicide for the K03s. It hella fun though, for a short blip.

Yeah, until your turbo blows. Get the TIP off and check the end play on the impeller, if there's any wheel left in the housing!

Man, what a mess. http://****************.com/smile/emthdown.gif I think we are all curious about ol' pugi03 that took one for the team.
List your codes!

Re: (slowonder)

check your n75 valve, which is the stock boost/wastegate controller . . . if you blew it or it is unconnected, then it will run off of the wastegate spring, which, in my car, is right at about 4psi

No, the n75 wont control boost it cant see, he has a diode. I suspect something is very wrong with that many codes.

okay guys here are the codes
p0136
p0036
p2257
p0414
p0102
p0420
p0141
p2400
p0031
i said twenty codes but it repeats (didnt notice that) so here are the codes so figure out what is wrong.
i went to autozone and they checked the code with this yellow thing i forgot the name (sorry). i installed 3' downpipe and sometimes it threw off my ho2 sensor.
okay here are the symptoms of my car. i have no boost over 2psi, it feels like limp but not quite same above 0 psi i feel boost kick in till 2 psi. and my DV shoots shhhhhhhshssss sound normaly. i dont have boost leak (i checked but not sure of it that i checked it for sure). my turbo was cranked but now its in normal mode.
so... any idea what's wrong?

my guess s, turbo waste gate, n75, (some sort of air pump, one of the code says it).

p0136 bank 2- 2nd 02 sensor, no big deal
p0036 bank 2- 2nd 02 heater circuit, not a big deal either
p2257 SAI System Control "A" Circuit low, SAI related.
p0414 SAI Switching Valve "A" Circuit Shorted
p0102 Mass or Volume Air Flow Circuit Low Input
p0420 Catalyst System Efficiency Below Threshold (No Cat)
p0141 O2 Sensor Heater Circuit
p2400 EVAP Leak Detection Pump Control Circuit/Open

Those are all of what the codes are. It looks like you diode modded your sai pump and left your 2nd o2 sensor unplugged. The MAF code is not good, and the 02 sensor heater circuit (1st o2) isn't great either. You probably should clear the codes and see if they come back. If they persist, clean the maf and get a new primary o2. The shorting the sai is something I haven't seen before, did you try to disconnect it or wire around it?? Your turbo was cranked but in normal mode? can you explain this?
And did you just go into the engine bay and start unplugging stuff or what? None of these really point to much turbo related stuff..

Re: (themachasy)

In my bentley all of these items are grounded through the same wire. http://****************.com/smile/emthup.gif You have to hunt through the pages to find obtuse line numbers to notice this.

hey guys, i was going throgh my old paper works and found my dealer check up documents. i took my car to dealer couple years back and they fixed my acceleration paddle sensor. so i was wondering if its possible that the same sensor got knocked? is this could causing all of this meaning no boost no acceleration(more like low or slow acceleration).
