secondaries coming on at 3800 rpm.. even at free rev
 

Still trying to tackle this problem. Talking to a few forum members, it seems my secondaries are coming on even without load. What all can cause this? it is poping and crackling at 3800 and I can't push it past it free reving nor in gear.

If it won't go past 3800 at all, then it sounds like the secondaries aren't coming on.

no secondaries aren't supose to some on at all during free rev in the first place

i think they are supposed too come on and yours arent thats why its acting fucked up

i think..... your wrong. That would mean im going lean, im clearly not going lean

2 v 1 this could get interesting

what?

This is a funny thread.

I think Keithrulz is talking about the aux ports, those are the only things that come on around 3800 and are load dependant. and those wont make you run lean.

Secondary INJECTORS are supposed to come on at 3800 under load or not.

If they DONT come on, you'll run CRAZY lean, cuz your primaries will run at half pulsewidth!

So lean, in fact, that it won't go past 3800 at all, like whats happening to him.....

^^ so does that mean we win because i no were right since when does putting more fuel in make u run lean

2 v 1


Two people have one opinion, you have another.


Now the score is 4 v1.


I declare this match of "Who knows what the fuck they are talking about" to be decided.

umm no your all not right. free reving doesn't activate the secondaries it's strictly primaries at free rev, secondaries are activated under load, and free reving isn't load enough to activate the secondaries hince why they arent SUPPOSE to be activating in a free rev situation on a properly functioning car. wow i need real help not this nonsence. it bogs because the air fuel mixture is too RICH the secondaries are flooding me out being why i get backfiring and horrible smell of GAS/unburnt fuel fumes... and no im not talking about auxilary ports it's a turbo 4 port

ftw us and wasnt he asking a question why did he post if he thinks he knew the answer

Hopefully Icemark or Aaron or someone will step in and settle this.

I don't know the answer.. i know what the symptoms are and what the problem is but not the solution to the problem.

I have no idea who is right. So why dont you find some kind of data to prove you are correct. Otherwise the seems to be a concensus against you here.

yes i hope

:crying: weah

im telling you your secondaries are not turning on just trying to hlp good night

5 vs 1

your injectors are staged to come on at 3653RPMs and are not load dependent, get that through your thick caveman skull...

how could it be running rich after 3800??? think about it, the injector p/w is cut in half when the 2ndaries come on.. the only thing that would cause the problems would be 2ndary injectors not firing when ecu wants them on = primaries only at half p/w = cant rev past 3800 because of very lean fuel mixture

I would check your connection/wiring to your secondary injectors, one or both could be loose or corroded

:dienewbie

Why would the secondarys be only load activated, cars are the same free reving or in gear, not like they have a mind of their own

Oh well he was totally :pokeowned

Hey, keithrulz, listen to Karack. For some reason everyone has a wild hair up their ass. Listen to Karack.

i guess i was miss informed by what i thought was a reliable source... okay well then i still need to know why it's happening either way. Are my hot start problems related, my compression is at 90 front and rear all faces. its possible i could have a vaccum leak but if i do i'm having a hard time finding it.

So? Why don't you get your head out of your dark spot????? Your clueless. Stop posting.

Secondarys only come on line if the the car is being driven under LOAD and above 3800 (give or take a few, I'm not going to argue aove three hundred rpm).

That said, secondarys will come online just sitting in the driveway and *free reving* as it was put. This can only be accomplished by pulling the vauum hose off the boot/pressure sensor and plugging that vacuum line . The pressure/boost sensor NOW sees atmospheric pressure and is fooled into thinking it's under a load and once you rev to 3800 rpm, give or take a few, the secondarys will now come online just sitting in the driveway. You can read the series four non turbo FSM, FUEL section to see this is a common trouble shooting technique. Well, common to anybody who read the FSM.

Another possibility is having the wrong pressure/boost sensor in the car. The voltage output of a non turbo vs a turbo are DIFFERENT and might cause the problem. One is a two bar sensor and the other a one bar sensor.

I'm just answering the question as to what could cause the secondarys to come online while *free reving* in the driveway. I'm not saying he's running rich/lean or inbetween. Just answering the original question. "What can cause the secondarys to come on line whilte *free reving*.
