Just to be sure:

 

Don't swap out your harness just yet. Do you have a wiring diagram of your car? If so, check your wiring with a multimeter that can test for continuity. I'd start with your IAT sensor wiring. Are you throwing any codes? If you need help with this, just ask.

Where's xeno when you need him?

Just to make sure, you're not low on oil, are you? Don't give up. You're close to finding the problem.

 

nice suggestion!!

 

Just watched the vid. Thats one wierd ------- problem, hahah.
Where is the boost gauge getting its signal from? Is there anything else T'd into that line?
If you go part throttle, can you rev all the way to your limiter w/o any problem?
If yes, can you take a vid of the boost gauge while: Holding steady revs at say 7k, hold the car at the same revs w/ the brakes, and slowly feed in throttle until your at WOT.

The fact that you're pulling 10" of vacuum at WOT is very ------- wierd.

 

hmm i can go all the way up to my rev limiter if i dont get all the way on the gas and maybe hold it at like 6 psi or so part throttle. It will go all the way up.

alright ill try to make a vid asap of that!

 

Where is the boost gauge getting its signal? Is there anything else T'd into the line?

 

Its t'd off from the back of the intake manifold and is tied into the evap purge control valve thing on the back of the intake manifold and t'd off to the wastegate too.

 

ok i t'd it off so its only t'd off from the back of the intake manifold and the wastegate. It doesnt have that evap thing t'd off in it anymore and i did a continuity test on the vtec oil pressure sensor and the vtec solenoid from the plug to the ecu and they were both fine. The grounds were ok too. And it still did the same thing. If u keep your foot down to the floor while its cutting out eventually it throws a check engine light for 22 vtec oil pressure sensor or whatever. But everything checks in ok! I even replaced the whole assembly just in case and it did the same thing!

 

It runs even slower then my stock 1.5 vtec :P
I didn`t know that it is physcially possible for the gauge to read -10 while at WOT LOL.
anyway I cna only think of the followings:
1) the TB some how closed/half shut while ur flooring it.
2) your turbo is spinning backward LOL
3) huge blockage within the charge pipe ( any soft rubber section within the piping? )
4) super retarded cam-timing , exhauste valve open at compression stroke.
5) super miss-firing or retarded ig-timing, which fires way after TDC.
6) boost/vaccum leak between IM and head, could be vaccum lines too <-----**** VERY POSSIBLE, CHECK *****

 

if you map sensor isnt enabled threw your ecu then thats def why, 6 k is where almost every car ***** up, only wierd thing is they normally throw the cel
