Blew up again...Doing it right this time!

[Realgib3]

I will do that reset after I do the bsd tonight.

I would also guess the reason people have this issue with an upgraded vvt is bevause it may to more force to move than a stock one. Not sure but its a possibility.

make sure u disconnect both terminals, not just negative... i wrote it wrong in that last post.

No lie when I did the hard reset I never got that check engine light again. Tapafucku!

You forgot holding your left testicle between the thumb and pinky finger of your right hand while simultaneously gyrating your ass on the instrument panel. That's for the real absolute-never-get-a-code-in-your-life-again-reset. I swear you'll never get a code again.

I never actually checked to see if there was anything installed there when I first got the block back.... @SPEED6 KILLAH hopefully you can chime in on this one just so I can be sure...

Sorry to answer you back late be I'm busy work a lot.. But no I didn't install the BSD and add it a couple of other things to supplement for the Bsd. I pm you with the list when the motor was on it way to you.. If you have any other question feel free to pm or text me..

Horry shit batman traction is for pussies lol Damn 6466 ms3 ftw. Do it evo style and make 800hp with this turbo. Just watch because some PTE turbos like to become shrapnel grenades.

Yeah turbo is sick, spools really well and feels great right now, just on spring pressure. As soon as I get the PI fuel setup complete, I'll be turning up the fun knob

Also GREAT news. Looks like everything has been resolved by installing the BSD and clearing the code. Drove 30 miles tonight and it ran perfect the whole time. Stay tuned for some vdynos probably next week.

Alright guys I need help.

Long story short, I finally started getting on it with boost set at 14psi and I get insane amounts of (EDIT: WOT) KR at ~2.0 load and 5-5500rpm +

Details:
Car runs fantastic until that point. No funny noises, no jerkyness, trims are dead on, afr is dead on, BAT's are <100*. Honestly everything runs so perfect it's not even funny. Even seems like (sure it's just in my head) that the car has higher compression than the old motor because it's soooo responsive off boost and spools this turbo pretty damn fast. Also NO CELS. None

What I've tried to remedy this so far...

new ghes
inj seals (again)
spark plugs
octane booster
moved an ic pipe that was hitting the oil pan

Anyway I'm out of ideas right now, so anything you guys can throw out there would be helpful. Only thing I have left is it's possibly building a bunch of CC pressure, but I'm not blowing oil out anywhere, dipstick's staying in, and my catch can seems to be picking up a normal amount of oil. also, when I took the IM off to do the seals again, there was barely a drop of oil in that.

oh and btw I updated my APmanager and now it won't connect my PC to AP, so I can't lower timing, but even if it's real knock and timing needs to be lowered, that still means there's something wrong because I'm only running 15* at RL with 2gal corn and now octane booster at only 14psi.

looking forward to some ideas so I can actually get this thing going fast because this sucks!

I know it's dumb, but did you replace the sensor with the motor or using the old one?

[Realgib3]

The knock sensor? Using the old one, but I may replace it now just to see if that's the problem.

It's just so insane how well the car drives until that point, plus NO cels at all, NOTHING.

buh idk

[djuosnteisn]

Your having KR at wot? Or at PT? Did you get the Cam pos CEL taken care of?

[Realgib3]

Originally Posted by djuosnteisn Your having KR at wot? Or at PT? Did you get the Cam pos CEL taken care of?

WOT only, no PT kr at all to speak of and yes, that code was due to low oil pressure because the BSD plug was not orignally installed. As soon as I put that in, no cels at all.

[Etipp98]

Yeah, I was referring to the knock sensor. Either way, you still gonna show up thursday?

[Realgib3]

Originally Posted by Etipp98 Yeah, I was referring to the knock sensor. Either way, you still gonna show up thursday?

Yeah I'll be there, just no WOT above 5500 and it runs perfect. Unfortunately the fun part is >5500 lol.

[Etipp98]

Yes, I can now agree that is true.

[Realgib3]

It sucks too because it doesn't knock near as bad, if at all WOT in 1st and 2nd, but 3rd and 4th are terrible

[Tomas]

Post a log.
Check spark plugs. Condition and gap.

[rodrigo]

the title killed me , "i blew up again" .... totally killed me ....ty

[Neverlift]

Yes Rod, what you were completely incapable of doing, some of us have already done. Some, multiple times.

[rodrigo]

u guys are sure crafty

[Realgib3]

can't post a log because AP won't connect to PC after the last update. Trying to get that fixed now.

The plugs I just pulled out looked fine and gap was right @.26 where I left them. Put new plugs in anyway just to see and still getting the exact same results.


Thanks for the input though guys, I'm sure if enough people throw random shit out there, we'll get it figured out.

[Deldran]

Just throwing ideas out there, i am by no means as good at this as several other people. But could it be false kr. do you maybe have something in the engine compartment moving around enough to cause this.

I wouldnt think it is because it seems to be pretty consistant but just trying to help the brain storming process

Definitely thought about noise but I think I fixed the couole rattles there were, and the fact it's worse with more load, ie 3rd gear and up makes me pretty sure it's real. Suuucks so bad my AP wont work right now.!

My first thought was false KR as well. You are running E85 blend right? I thouhgt I read a couple gallons. That load/timing/rpm combo doesn't seem overly aggressive. You say you even dumped in some octane booster on top of the ethanol and still seeing KR? If it keeps showing up at the same RPM point you might be hitting some weird frequency/resonance that is triggering the sensor. You do have BSD, I am sure several stiff motor mounts, just had the entire front end apart. Even on a stock engine the KR sensor turns off around 5500.

Too bad you don't have the AP or you could go drop a few degrees and see what happens. Can you add more Ethanol for a test. With for example, 2 more gals you are still knocking, I would be pretty confident it is not real. Only thing against the false KR theory I see is that you say it is only in the higher gears....

Anyway, I am sure you are aware, but once you decide if real or not you can then go adjust the KR offset table some at higher RPMs to make it less sensitive.

Good luck with everything. Hope you get it figured out. I have been watching this one for a while.

[djuosnteisn]

I've only seen one bad knock sensor before... and it did show unusually high KR, even when there was plenty of octane. The best tests to determine if the KR is real is to simply add more octane. Even if it's a tank of race gas (as pricey as it is), if your still getting KR at that point, start looking into mechanical causes... rattling pipes, loose / faulty knock sensor, etc etc.

[Realgib3]

Yeah Im leaning toward somethin not octane related since Ive added another gallon of e (3 total) and 2 bottles of octane booster and still see the same counts of 10*+ kr. Plus the plugs have lookedto fibe the eholeangle time. Will check more stuff tonight when I get off work.

[Chimmike]

Octane booster does dubious things, at best. Maybe .1-.2 point of octane. I don't like the additives many of them use.

Close plug gap to .025? IC pipe hitting VC?

mm vibrations maybe?

[Etipp98]

There is a sunoco station in willowick that sells the 260GT 100 octane..

Been there, may fill up with that when this tank is gone but I think I'll look into mech issues till then. I'm just going to make a checklist of all these posibilities and go down that one by one.

[SPEED6 KILLAH]

Did you reused the old timing chain??

[Realgib3]

Yes. I will check that again today but as of Mondat it was as tight as ever. Definitely so.ething to check again though.

Hmmmm it could be tight when install it but onces you go Wot and plus the heat it stretches.
Easy way to found out if the chain is stretch is look at the bottom of your valve cover and you will see marks like in this picture

Thanks Pablo! I'll look tonight!

[2008_zoomzoom]

@Realgib3 i had the same issue with atr and ap manager. try uninstalling the ap manager and reinstalling it. i spoke with Cobb and it was something to do with the driver software not installing properly. it worked for me. i had this issue after d/l atr to my desktop after having it on my laptop. also , if you can, manually install the driver software. it helped. took the guessing game out. good luck with your car. cant wait for numbers!

[phate]

10° of KR at full throttle at that RPM, and it living, tells me it's likely noise. You would at least see spackling on the plugs, if not break the porcelain.

Timing chain is a good one. Pulley bearings are another thing to check. Any time I get to see a car in person that has this kind of issue, I just start shaking shit in the engine bay. Not like poke-poke, it doesn't move; grab shit and try to force it back and forth. Intercooler piping banging on the intake mani, exhaust or exhaust hangers rattling. SSOOOOO much stuff can make noise.

[Realgib3]

Update...

FIIIXXXEEEDD!!!

Alright so I stopped being an idiot and REALLY went through the damn engine bay and as @phate said I shook the shit out of everything I could find.

and not shit moved lol

But then I noticed a ground wire that looked loose sitting right near the hard coolant line that runs over top of the trans... also looked to see that some of my ECU wires were un-taped right next to the power wire to the starter... Tightened up that ground and re-taped alllll the ECU wires and power wires and voila, car fucking rips.

If 16psi feels this good, I can't wait to feel mid 20's!

Thanks everyone for all the brainstorming. I'll post logs as soon as I can get this damn AP fixed.

[SilverDemon]

My issue was related to a faulty 2nd O2 sensor. The ecu will dump fuel like mad to try and put heat in the sensor. Mine was a rich knock, and I never saw +10° of knock with this issue. Could the missing bsd plug caused some issues with oiling?


edit: haha never mind good catch

[jracer]

Awesome !

[Dano]

shit just saw the mention..glad you got it fixed.

[Realgib3]

Yep fixed...the broke again lol. Got my AP fixed and got 5 solid days of running great, then crzy knock came back. Idk what it is now just annoyed but I'm gonna tear into it tonight again to try and figure it out.
