FIXED !!!

WOOT !!! Well the knock sensor code is gone anyways. . . . . . the lazy blue 02 has now switched sides to the lazy yellow 02 . . . .should I replace it ??

Anyways turns out the freeking knock sensor was full of oil . . . dont ask me how dont care it runs great !!!

WOOT WOOT !!!!

nice!!!! so you switched the O2s and the readings are switched too? Now you need to figure out which O2 is bad :).

Yup , took your advice and switched them , the yellow one now is a carbon copy of the blue one from the old tunes .

Im pretty sure evilive uses the 1st o2 eg. bank #1, 02 #1 would be the drivers side front. Bank #1 o2 #2 is pass side front. . . . I dont think it does anything with the back ones ??? Anyone now for sure ??

Id like to replace em both roy but there big $$$ .

Also I haveto check my fuel pressure regulator or leaks . . . any ideas on the best way to go about this ??

wouldnt the 02s be replaced under warranty?

Yep, if knock sensor keeps showing knock PCM will pull timing, if knock isn't gone it'll keep puling timing until it hits the MINIMUM timing table in your tune, ohh wait I already PM'ed you that, ohh well an extra post :) glad to hear it fixed your problem.

If you bring a video camera ill bring the car in for warranty . . . . . . I can see it now on the hoist with a half dozen techs looking at it going . . . " what the **** ??? " :cool:

I think it was probably fine unill the car started missfiring with the crazy ass timing. . . .it probably ate som raw gas .

Yup you called it !! Im still only getting 20 - 22 degrees WOT . Its hella better but not what it needs to be just yet.

Any ideas on how to check my fuel pressure regulator ??

only if the o2 were switch to a new exhaust at the dealer or repair depo by a "trained" tech and not the user:barf:

You are probably still in the low octane table. You can get out by letting the tank go near empty then filling up. resetting the PCM might help... you probably already did this though.

I cant wait to feel the high octain table, just getting the air fuel ratio back in check and getting this much timing back feels like I picked up 50 rwhp and way way more over 5500 rpm . . . . shes a mean bitch again. I betcha I was down to like 290 rwhp it was running the bag :yuck:

How does that fill up **** work ?? Do you have to fill it right up ?? Why do you have to go almost empty first ?? Stupid pcm i need to reprogram from scratch . . . . when I get a tuner Im copying the high timing tables right overtop the low timing tables how u like them apples :p

Yes go to almost empty & fill her up as suggested, or try resetting the PCM. Also, according to your airflow readings you are in the 400rwhp range? well atleast your sucking enough air to have that much power, this isn't 100% accurate but gives you an idea of how much air your engine is sucking & its sucking a ton of air, enough to make over 400rwhp.

400 RWHP eh?:cool: My guess is that he is probably around the 380-385 mark.:p

Good to see you got things on the right track Dave. Now get some AFR heads will ya.;)

Actually, a 25 % tank fillup up is apparently good enough to resxet things, from what I hear.

Glad to hear things are better.

117.00 for a new o2 sensor *gulp* Anybody know where you can get these cheaper ??

I put n 20$ but that was 19.x literes and I was close to empty "check guages" light was on. . . . hmm how big is our fuel tank ?? . . . I still taped low timing afterwards. . . maybe I should go stuff some more in there and tap it again . . . . automotive science right Amit :p

Our tanks are about 60 litres, so that should do it I think.

Who's O2 sensors are you looking at? The Delco ones? I think there may be cheaper ones through Mopac or lordco, or whoever.

I have to eventually get another for myself, cuz one got damaged when installed in my headers... the bung hole was too small and it crushed the sensor as I screwed it in. Who'd have thought you have to double check something like that? But, not surprises me in this industry.

Wow thats a WICKED price. . . . .I want to do a little more digging on the problem before I spend more $$$ though. . . . .

The thing is I dont understand why im getting constant codes for both left and right bank o2's not switching and perry has the same headers without any codes. Everytime i pull them theres like 6 stored , Ill delete them and a day later a whole bunch more of the same bloody code. I hate that light

WTF, your knock sensor was full of oil? Is the passage cracked, or was there a leak onto it? The knock sensor should be threaded into a dead-end hole with no passage into the oiling or cooling systems. That would worry me if I were you.

nah . . . I have a theory. . . theres holes along side the intake runners , oil could have spilled over the top of my funnel and poured right under the intake through those runners/ pockets whatever you wanna call them . I checked it out pretty good no evidence of cracking or damage I think its just pure dumb luck. The oil looked brand new too ,very clear like its never seen the inside of the engine. Ill keep an eye on it though . . .
