Hello,
I have been a member of the org for quite a while, really don't post much, just use the great info that is provided on here. So far i have an frankencar intake, warpspeed y-pipe, removed the resonator and replaced with straight pipe, stock muffler, and udp. I want to stay n/a and was wondering what other things i could really do? I tried to get the timing advanced but the damn dealerships wont do it for me, said it wasnt worth it and wouldn't see any real gains. So i was thinking i could buy the SAFC-II and change the timing through that, but i dont want to destroy my car cuz i really dont know anything about a/f ratios. Just need some suggestions thanks. Performance only.

you cant get the timing advanced "officially" through the service department. you have to do it off the record by paying a tech to do it.
as yes, it is worth it.

That is something I need to do also.

andrew3616

How much of a difference i have read all of the post i could search about it. so what would my strategy be when i go to the dealership. lol just curious how everyone did it

as i have stated in all the threads about this....
sit outside the service department where the techs park the cars after servicing them...offer him $50 to do it...profit

andrew3616

well ill give it a shot, thanks

what kind of performance gains would you see from doing a timing advance?

Headers will give probably the most N/A power gains. Then tuning with an AFC afterwards will probably gain some more depending on your stock A/F ratio. I think some people have been messing with the intake manifolds on the 3.0s but I don't know anything about it so I'm the wrong guy to ask.

you could also get your ECU upgraded, like from technosquare or something like that.. i was thinking about that, but i'm not sure how safe it would be with an auto tranny because it removes the rev limiter from what i understand.. some guy was telling me that i could get my computer chip altered to make my car faster at some local shops and im assuming it's that same procedure that he was talking about.. do you guys know if it's safe to let any regular performance shop do it?

Well i have looked over every timing advancing thread that i could find. Some people say each degree will give you 5hp but who really knows cuz so far i have yet to find someone that has had a before an after dyno. Advancing the timing just adjusts the base timing which in turn effects the whole power curve because that is what the ecu reads bases its timing off for the reast of the curve. So far im getting that it just makes the compression in the engine higher so you have to run high octane feul so that it wont combust just from compression, but rather wait for the spark. So it can be very dangerous if you run low grade gas in your car after a timing adjustment. I appreciate your all the help thanks. wanted to add something. I think i increses compression by closing the valves earlier. i think

it doesnt increase the HP

andrew3616

It increases torque?

foodmanry

iTrader: (15)

Meh...personally I don't think the timing advance does much. It does pretty much force you to use 91+ octane.

I had it in my 2k and didn't feel much, maybe a little mid-range RPM throttle response but that was about it.

As for dealers that will do it, MOST of them will. Just call up and ask if they will do it before going down there in case they say no. You pay for 30 minutes of labor for the timing advance which runs about $45.

wyche89

thanx for the link soonerfan.. i read alot of the timing advance threads too... and what i got from them is that for a 2001, the ideal setting is 17 degrees, and it'll increase your low end throttle response.. correct? but you have to use premium gas at all times (which i do anyway) one thing i wasnt clear on.. does it improve gas mileage, and are there any drawbacks to doing it? because i think im gonna do it

SoonerFan

iTrader: (5)

nope....
HP and/or torque are not INCREASED

frees up HP and torque? yes
makes it avaliable at lower RPMs? yes
improve throttle response? yes

About a month ago I was at the only tuning shop here in Lubbock and i was talking to the owner about advancing my ignition timing. He told me that the Nissan dealership would flat out not do it over the counter because the EPA banned any type of altering to ignition timing because it changes the factory EPA est. gas mileage. I searched around the internet for a lil bit but had no luck. Anybody have any insight on this? And if this is true i dont know how u guys are getting the dealership to do this over the counter.

Wow, timing advance is overrated. Throttle response is bumped up a little bit (to neutralize the effect of my ghetto 2K SSIM)

But what you really want are headers. omg headers are NOT overrated.

SoonerFan

iTrader: (5)

my gas mileage was not effected
the gas mileage on josh's (irish) 00 was not effected.

i agree that the advance is over hyped on here...but i wouldnt say its pointless. i did notice the difference. it isnt huge...but there is a difference.

i have a 00 maxima my cooling fan starts and never stop until i turn off the car, is this normal? any help

Maxgig

iTrader: (5)

No that's not normal, but lucky it's broke in the on mode and not the off. This happened to a friend albeit his was a 4th Gen, he ended up changing out a relay. I don't know if thats your problem but I'm just trying to give you a reference point to start from.

mtorre69

ok, thank you but its not on all the time it starts until is normal temperature but after that never stop

Here is the conclusion of this thread. I did exactly what soonerfan told me too today and i live in nashville, tn which has about 3-4 local nissan dealerships. I went around to them and the first two wouldn't do it, even with me confronting some techs out of view and telling them i would give them cash, mind you im a pretty convincing guy it wasn't just that straight forward. So i called up the last one that was in reasonable distance and talked to the tech guy and he said that they would do it, forget to mention i called the other ones and they all said no before i went an tried the cash method. So i pull up and the whole dealership is laid back i just pull my car in and the guy grabs a tech and he comes out with a consult and presto my timing was changed right in front of me. I also had the idel bumped up 75rpm. THe guy seem like he wasn't even going to charge me cuz it took less than 5 minutes, but i felt bad and gave him a $20 bill. After the timing advance im very impressed and would recommend it to everyone. THe car feels like it should come from the factory like this but nissan know that everyone wont put premium in so the leave it at 15 to prevent knock. Very good mod in my opinion. Makes a noticeable difference

Nice. I'll have to get this done then.

Glad u had success. This gives me hope. Ill have to try it too.

wyche89

what did you get it adjusted to... 17 degrees?

andrew3616

yeah, i could of went higher but i figured that would be enough considering that i'm not any racer or anything just want a faster street car

How can valves closing earlier increase compression? That doesn't even make sense. A domed piston, different head, or milled head would increase compression, valve timing has nothing to do with it. A higher lift cam could cause problems with valve clearance, but valve timing won't affect clearance or compression.
