how dangerous is this???
 

how dangerous is it for me to be running with no fuel management right now? i've got my timing retarded almost all the way, running 93 oct., intercooled (and it's actually pretty cool out), and not boosting over 3 psi, if any at all?? i know pat said he did this for a while, but is it really that dangerous? i'm seriously in vacuum most of the time, so does it matter? but every now and then i'll get it up to about 2-3 psi just so i can blow off ;) anyways, i didn't have a choice, my ecu isn't ------- here yet, and i missed work yesterday cause i didn't want to drive it that far like that. hopefully, my ecu will be here today, but i just want a piece of mind that what i'm doing is not ------- up my engine :-\

Re:how dangerous is this???
 

I would'nt worry about it man. Just keep out of boost as much as possible. ;D

Re:how dangerous is this???
 

yeah, according to the a/f gauge ::) it's running rich, but i'm just paranoid and thinking i'm hearing detonation, but it's prolly just an exhasut leak cause i only have 3 bolts on my down pipe flange ;D

Re:how dangerous is this???
 

Is it really worth ------- up your setup and losing your low down power just for the sound of the BOV? and for only 3 psi as well, I wouldnt do it, what are you doing for fuel by the way?

Re:how dangerous is this???
 

well, it's kind of impossible not to go in to boost at all, 2-3 psi isn't really ----, it doesn't even kick in the map sensor check light until over 3 ??? and i'm not hanging out in boost, i'm watching my boost gauge instead of my tach, and as soon as i get at about 1 psi, i'm shifting, i'm just saying, it's gone up to about 3 psi a few times, but i'm not holding it there if you know what i mean. i'm going to be running uberdata as soon as my ------- ecu gets here, i've been waiting on it since last week and should be here today.

Re:how dangerous is this???
 

why not just unhook your wastegate ??? ???

Re:how dangerous is this???
 

don't have a wastegate, my down pipe is welded up with a block off plate for external wastegate which should be here thursday.

Re:how dangerous is this???
 

how bout u disconnect the charge pipe and just run a filter again until ur ready to boost?

Re:how dangerous is this???
 

and kill my turbo spoolin the ---- out of it, no thanks, i think i'm safer as is :-\

Re:how dangerous is this???
 

because thats not good for the turbo.

projekteg: how is it only hitting 3psi of boost with no wg on there?...are you just not taking it all the way up?

Re:how dangerous is this???
 

yeah, exactly, i'm shifting according to the boost gauge, not the tach ;) wastegates are over rated, my right foot is my wastegate :P it doesn't really spool up in 1st, i've had it up to about 6k rpms and only 1 psi, but as soon as i shift to second, it's at about 3 psi's then i just let off the gas and get out of boost, i'm in 5th gear at about 40 mph just to stay out of boost, this fucker's gonna spool up nice though! i'm glad i went with the .63/.60 ;D

Re:how dangerous is this???
 

3psi from that 60-trim is prob. like 5psi-6psi from a T-25, RBwhatever, or other small turbos.

I hear if you un-hook the temp. sensor it will make the car run a little richer.. But that's "what I heard".

BTW as you know A/F gauges are almost totally useless. My A/F guage reads SUPER SUPER LEAN 24/7, but my plugs, and exhuast ports are blacker than all my neibors.

Re:how dangerous is this???
 

I have been running for a week with no fuel management: I have check valves on the map,colder spark plugs, intercooler,back down the timing, and running 93. I set the wastegate at 4 psi and I have not heard any pinging or (Subaru sound). My turbo is a 12a from a Starion. I took out the spark plugs and they were barely white running lean but running lean makes more power. I am just waiting for my fuel injector clips but as long as you don't up the psi I think you will be fine. The Y8 is holding strong.

Re:how dangerous is this???
 

Yeah, if you unhook your temp sensor you'll run rich because the ECU thinks the engine is never warm.

Re:how dangerous is this???
 

yeah, it's unhooked anyways cause mine goes in my intake pipe and i haven't drilled a hole to mount it yet.....

Re:how dangerous is this???
 

i think he means the coolent temp sensor

Re:how dangerous is this???
 

Not your "Intake temp sensor" your coolant temp sensor, which is located in the side of the head underneith the distributor. Also you dont simply "unplug it" because what would happen? it would throw a CEL and it would freak out, and it would go to some werid base value and wont do what you want. So what you do is.. Unplug it, (find another coolant temp sensor, d-series/b-series anything you got laying around off a core motor) then plug it in to that, and let the fucker dangle in your engine bay, so the circuit is completed and its reading whatever temp is in your engine bay, which is about 100 degrees or so. This will trick the ecu to thinking your always cold, the idle will bounce around a little bit. But this is good for 5psi, this is exactly what greddys "Black box of lies" does for Fuel management. Very HMTish.. but works

Good luck, and even if you dont do it, 3psi wont kill it, and if your really really parinoid, just unclip the internal wastegate clip and pull of the wastegate actuator rod, the flapper will stay open and wont boost at all.

Re:how dangerous is this???
 

Well I pretty much can't top that last post.

You could always stick a resistor on your o2 sensor feed wire that would trick it to running super lean.

Re:how dangerous is this???
 

sweet, it just so happens i have a blown b18 i can take it out of, i'll get on that today after work, i thought they were talking about the iat sensor, which is also dangling anyways ;) as far as the wg trick, i have no wastegate at all, as in my down pipe has a block off plate for an external wastegate, but my external wastegate isn't hear yet, so my right foot is my waste gate ;) yeah, i pulled my plugs last night and they were a little light, not too bad but not as dark as i was hoping. i drove to work this morning and stayed out of boost completely, i'll get some new plugs and do the temp sensor trick and do a couple pulls at 3-5 psi and see how the plugs look then.

Re:how dangerous is this???
 

If that's the case with the temp sensor, couldn't you throw a potentiometer in it's place with the same values as the sensor and adjust accordingly? I think i'm gonna hafta try that and let ya guys know ;)

Re:how dangerous is this???
 

sounds like a good idea slo crx, i love POT's can use them for everything.

vanilla ice (kevin) you're so ghetto it's funny.

Re:how dangerous is this???
 

why would i want to run lean? or did you mean to say rich?

Re:how dangerous is this???
 

resistor would essentially "hide" some of the voltage that the o2 would be pumping out, thus the computer wouldn't read it's typical .45 volts, would read .1 instead - thus tricking it to thinking that the o2 sensor is reporting the lean condition and then taking itself out of the closed loop operation or going to a default "save my own ass" fuel load.

I'm unsure if that can be worked out in combo with the coolant sensor trick.

Trick computer that you're running lean to compensate for your ghettro setup, that's what I was getting at.

Re:how dangerous is this???
 

well, it's all good, i'll just do the coolant temp sensor for tonight so i can hit 5 ish. i talked to the man about my ecu today and he over nighted it today to make up for his slackness, he only lives 6 hours away, so it will definitely be here tomorrow. sorry to dissappoint you guys, but no mo ghetto :'(

Re:how dangerous is this???
 

Just take off the block off plate to the wastegate, unless it's somewhere where it will melt something.

Re:how dangerous is this???
 

i would only take it off if it would melt something, i'm ghetto son ;D

Re:how dangerous is this???
 

oh, and the only way to properly find out what's going on in your engine would be to do a high rev shut off.. ya see when you're driving around town and you hit boost and your motor gets that nice 17:1 a.f.r. then you idle it for a while your plugs are "somewhat" turning back to normal.

so you really don't have the exact figure of what's going on since you're pulling the plugs after you get home, after they've been washed clean a little bit.

this is from the old school of hotrodding when our motors got 8mpg and we didn't have fancy electronic gadjets like o2 meters and where we also were able to brew our own meth in our OWN bathtubs, not no mexican meth factory.. well j/k about the meth part.

Re:how dangerous is this???
 

Stock O2 sesnors are about worthless... More a PITA then anything..

Re:how dangerous is this???
 

well, i did the 'coolant temp sensor trick', it definitely runs rich, idles like ---- though just like a cold morning start at about 1800 :P but i took her up to 6 psi and the a/f gauge was full rich and heard no detonation. my ------- map sensor cel doesn't even come on any more ???
