A Ks sensor can really make a huge difference in a race.

 

just a friends brother, i wasnt too much into racing and such then, so i really didnt care. im sure someone here has raced with people in the car on the streets, even worse.
i expect to run better than a 17, auto or not. wouldnt u?
oh crap, i didnt know i was running 2.44+ 60 times. obviously thats y im asking buddy! says much about u to read such a stupid thread and reply to it.
just wen u were startin to be helpful man, comon. u did reply, did u not. i needed replies.

for those who have replied in good taste, thank u, ill take ur thoughts into consideration and do wut i have to do come monday. like i said i know i have a cel light, but i dont see the problem in running it just to see how it does with problems. that way wen i fix the problems i can tell ALL BY MYSELF how much a ks hurts, and how much a o2 hurts, but i guess thats a hard concept for some people to understand. all i wanted was advice and knowledge on my mechanical problems if thats too much to ask.

 

now, i dont know if theres a pepboys by anyone, but does anyone know if pepboys will change an o2 sensor or is it better off to go somewhere else, "stealership". either way im not buying an o2 sensor from nissan, $170ish compared to $80ish at pepboys. i would attempt it myself but i know its hard to get to, plus i really dont have too many tools at my expense to do it.

 

I had to point out how dumb you were. You ran a 16.0 with a 2.44 60ft, that's almost normal. Then you ran a 16.8 with a 2.68, that's pretty normal. What is the point of this thread? Do you think that because the 60ft was only .24 slower then your run should only be .24 slower? A y-pipe takes off maybe .2-.3 from the stock time so I'm not sure why you were expecting to run high 14s like you said.

 

the point of this thread was to see if the ks problem was the only reasonable explanation. now ive learned that a ks problem does hurt performance as much as it hurt mine. 14s was just a rough guestimate based on other peoples cars and mods, atleast a low to mid 15. i obviously tried to run better than a 2.44 60ft, anyone does. but my problem probably does not allow me to do so, now i understand that better. Comon Dave, wuts wrong with an honest question, not a "dumb" question, they dont exist. uve probably been doing car "stuff" a lot longer than i have, thats y i ask the org these so called "noob" questions hoping for a nice, respectful response from those that can give it.

 

I'm 80% sure that it might be the KS, but what you're expecting out of your car isn't going to happen. I doubt you'll see anything lower than a 15.6 with the mods you have. Where are all these automatic maximas with your mods that run high 14s?

 

well, i dont know man, i guess im just a misinformed kinda guy, or a very hopeful one. on monday imma change o2 sensor alone b/c it coulda tripped 0304.. if 0304 comes bak ill change that asap. do u know if pepboys will do it? if not ill just find out monday mornin. maybe soon ill go bak to the track and shoot for a 15.6 then. heck, ill probably even send u a pm just to let u know wut i run for the heck of it. if my car doesnt perform the way it should, imma go out and buy a M3.

 

If you have a basic set of hand tools, and a long extension, you can change your own knock sensor, and save mucho dinero. All it takes is a socket wrench, extension, u-joint, and 12mm socket. If you don't have these, then it's probably time to invest in some tools. The money you'd spend on labor will far outweigh the amount you'll spend on a 100 pc tool set. Pep Boys will more likely than not say no to changing the ks. If they do what the FSM calls for (removing the intake manifold), they're in for hours worth of work. However, they probably won't want to be subjected to the bloody stump method, either... read through the stickies to find the write up on ks replacement, and an o2 sensor shouldn't be that hard to replace either.

 

yep, I also think he'll never see < 15.6. I ran 14.9s consistently and I'm 5-spd w/y-pipe being my only mod.

 

Why are you guys hating on the poor guy? I ran 15.3@91mph at the track when I went with my automatic, im expecting 14's this time around switching to stock rims (I ran them with my 22lb G35 rims),added UDP(does nothing probably), and the 00VI is gonna help me out...

When I ran the 15.3@91 I had ypipe/cai, thats IT.

MaximaSpd85, if you need help changing you KS send me PM since were both from the Miami area.... Always nice to meet a few new heads.

 

u people in the south Florida area better watch it....or else....

the hurricane will get u and your MAX!

 

Omgomgomgomgommogomgomgmoggogmogmg Im Gonna Die.

 

 

I own a manual tC and a 99 stock GLE. I would say they're just about equal, though I've obviously never ran against myself. A manual 4th gen Maxima should be noticeably faster than any non-blown tC though.

 

They have superchargers for the tC?

 

Yep they do. Saw it on TV once, one of those TC commercial where this kid was saying that anyone can customize their own TC even put a supercharger on it, then he mentioned about a place that did it.

 

15.6 blown tranny, i/y/e/cat and yes, if you need help with the KS let us know..

 

Your tranny wasn't blown then..

 

thank u much sober, i probably will send u a pm, u too gtr rider. u ran a 15.3 with about the same 60ft i did, so imma shoot for that instead of a 15.6. and bout that hurricane, thats messed up cuz its actually killed people.

 

the tranny wont let you kill it(for the most part)

for the auto tranny think of O/D off = 3rd gear, 2 and 1 are what they say.

when i """launch""" onto the freeway i start in 2, rev till just past 6k, and shift to D with OD off(thus meaning 2nd to 3rd gear) with the lag of the shift it will shift around 6400rpm or so, into 3rd.. after that its fast on up past 80mph(where i have to stop if i see headlights, might be a cop... 100mph ticket wont be fun)

try to practice like that on streets and freeway onramps where you can. i have alot of fun with mine, i shift 2, ODoff, and D allll the time. its like having a manual for people like me who cant drive one

 

well, i often dont shift manually because of wut i hear (mess up tranny), but i guess a few times is ok. how fast are u going once u shift to D, cuz the owners manual says not to go above 70 in "2". im not sure, i have a friend that says "o/d off" is one less gear. but i always hear people say "o/d off" is quicker. it didnt show in my runs. another thing, wen i shifted from "1" to "d", there was no lag wutsoever, hard shift is wut i felt. it got me thinkin maybe i should do it that way.

 

o/d off means 3rd gear max.

i shift from 2 to D based on RPM, not speed, but ive gone over 70(rpms are way high past there)

you will get more speed from a manual shift, higher revs than it would normally give you and such. try it out getting on teh freeway.. put it in 2 and floor it, youll hit 75 before youre on the freeway. thats what happens to me here alot anyway.

about shifting hurting your tranny, i think thats BS. last i checked its 100% ok to shift.

edit: just talked to a car guy.. hard manual shifting alot over time will eventually hurt your clutch.. but by the time that happens it would be expected.
aka: track days + fun driving now and then = A.O.K.

 

yes it was, stfu

 

Yeah ok..

"It didn't even slip on teh run omgmgmgomg!!!"

 

Automatics dont have a clutch?

 

not a clutch as you would normally think.. its computer controlled.

 

What are you talking about ? The torque converter or the TCM.

 

---DO NOT--- manual shift an automatic at the track. If anything buddy its going to hurt your times. I ran a 15.6 with my auto Max on the g-tech, and I ran a 16.4 when I manual shifted + power brake on take off. The automatic Maxima's tach-out before they shift anyway, if anything your hurting your time by shifting and its unhealthy for the tranny. I blew a tranny out hotrodding and manual shifting, don't claim the same fate.

As for KS, mine has been out since I bought my new 5speed Max. This one has full 2.5'' Warspeed exhaust system (ypipe, cat, bpipe, obx muffler) so with the KS out I could run with my friends stock automatic max fine. I put a 470k resistor in the KS sub-harness last night though, and you would not believe the difference. It amazes me, every gear pulls harder.

If you can't afford a KS right now, go to Radio Shack and buy a .99 pack of 5 470k 1/2 ohm resistors, throw one in the subharness with electrical tape and reset your ECU when you go to the track. Be sure to run premium gas with the resistor at ALL times, and run it for a while before you go to the track so the ECU can optimize. Good luck.

 

Ahh I remember the days when my KS was dead. My buddies SE-R Spec V destroyed me. Fixed it the KS and then I destroyed him. Max is a turd with bad KS
