what do i tell nissan on advaced timming they have no clue up here in north dakota and i have heard great things about this thanx

 

Our timing is electronically controlled, so advancing it isn't as simple as it was on older engines like the SR20 (you can't run down and get a cheap Sears timing gun and do it on Saturday). As far as I know, If you want your timing advanced, you're going to need to hook up to a machine and modify it electronically. Something like this should be simple for a trained mechanic. If the Nissan technicians near you don't know what advancing your timing means, NEVER GO BACK TO THAT DEALERSHIP.

Of course, it doesn't sound like you're entirely clear on what advancing your timing does. Timing advance helps produce more power by igniting the sparks sooner, providing more time for the fuel/air mixture to burn completely, increasing cylinder pressure, thus providing more power. If you're going to advance your timing, you're going to make the spark happen earlier, thus increasing the burn time for the air/fuel mixture in the cylinder. That's fine and dandy if your car isn't ALREADY burning up all or most of the octane available in the fuel. Most tuners who advance their timing switch to a higher grade fuel, or else they would experience detonation.

 

advanced timing is crucial for power in NA levels. There are only two ways that I know of to advance timing in our engines

Technosquare ECU can give you the advanced timing you want across the power band. Or if you can convince a nissan dealer to hook up their consult-II to your car, you can alter your timing +/- 1-2 degrees. I believe its a maximum of 17 degree of timing advance across the board. MaxGator and Sr20den are a few who have had this done

 

Dealer is the only one that can adjust base idle timing via Consult-II.

You can advance it up to 20-degrees and be within spec, however around 17-degrees you've modified the base idle parameters enough that the ECU will fight you to control idle speed. Therefore, your tech must perform an Idle Air Volume Learning procedure to advance further then 17-18 degrees. So far, nobody has verified this though.

Anyways, in hotter climates with 91-craptane, a few have reported pinging with advanced timing, so you might decrease performance during the hot season. Also, I still argue that this mod is only beneficial if you're an auto, since you punch it off the line vs. manual trans timing that increases to 20+degrees as you increase RPM to release the clutch.

 

I've had this done. Had my timing advanced +2, so I'm at 17 right now. The car rips when in midrange RPMs. Flooring the car from 45MPH has made me chirp my tires twice so far -- it's never happened before. The car revs a little higher at speeds now, yes. Stock timing had my needle at around 1800 @ 60MPH, +2 has me at about 2100. The throttle is a lot more responsive now and the feeling of the car just ripping is incredible and very addictive. The power increase is noticeable, and ill effects will only occur if you fill the car up at anything less than 93. Sometimes, I'd go out of my way to find a 94 pump and filling up with 94 makes the car even happier, if even the difference isn't extremely obvious.

 

i've been on 91 octane gas with TS ecu in 98-102 degrees F temperatures and AC here in the summer with no problems

 

interesting. blackbird explained the same asNYPD

 

RPM@Xmph is dependent on gearing and rim/tire size...timing has nothing to do with it.

 

It's the best damn mod I've done next to my drop. Hehehe, it didn't even cost a dime. It's great when you know service techs who work at Nissan. =D

Ice: Then why does my car rev higher at speeds now? I haven't done anything to my tires or rims...and I noticed this the very same day I got my timing done. It's not in my head because I remember participating in threads were someone asked what their RPM sat at certain speeds and my car certainly reved lower before.

 

TS doesn't modify base timing/partial throttle(closed loop) timing, only open loop timing.

 

Ice: Check my edit above.

 

No idea...engine RPM is determined by a mechanical ratio, no ECU tricks will change that unless you screw with the tach.

 

Weirdness. I'll have to look into that.

 

If you have an OBD scanner, you might try verifying your tach/speedo isn't off by more then is "normal" by Nissan standards.

 

I did the same advance timing as Arnold (same nissan tech). DEFINETLY recommended, but my rpm at 60mph is still at 2k, just like it has been as before the timing was done. The car definetly rips at higher rpm as well as does not lag once gear shifts, just shifts and pulls the car. Alot of people also recommended getting the VB mod done from Max tun. So thats the next step

 

so at what degree is a 2001 set at , and whas the best degre to have it advanced to , im going in for service and i wouldnt mind getting this done... from what i hear the best degree to have it advanced to is 17 , is that correct?

 

i'm not talking about cruising speeds.

 

I know...so your experience with TS+91 octane isn't related to the base idle being increased and detonation during low rpm closed loop operation.

 

15 is stock.

 

Oh it's true brother! The thing goes nuts at idle for some reason if you just up the timing and do not do the IAVLP. Bad idle, if it idled at all. I had this done the same time as my engine hesitation flash...

 

I tried going above 17 on my car with the Consult- It will NOT raise the timing above 17 either before or after performing the IAVL procedure. Funny thing, the "target timing" menu in the Consult will let you scroll up to like 21 or 22 degrees, but the adjustment will NOT stay. I never heard it ping in hot weather on 93 octane, but the engine is obviously flat above 85F or so.

 

ok so i tell nissan to + 2 on the timming and they should know what to do right anything else recomended besides vb mod just woundering cause iam getting my tranny flushed at the same time and also is there a way to tell this guy actually adjusted it at idel cause he wasent to sure about doing this well on the phone he said ive never done this nor has anyone ever ask so littlle nervus

 

It goes to 20 on mine, but I leave it at 17...

Wait, you have a straight up 5th Gen, right? I have 5.5th Gen...

 

so how much do you think nissan would charge for doing this? is it thier ussual 80 dollars per hour .. cause thats gay. and would i notice any differance if i set the timeing to like 16 or 16.5?

 

is thier harm to have advance timing, with Mods (i.e) y pipe, headers, intake, exhauast. Udp??? Will Advance timing harm your engine in the future????/

 

Only if you advance it too much for the fuel you're using. If you notice any pinging, retard the timing until it goes away.

 

do you think i can run 90 octane for 16 degrees advanced? and would i notice any differance in acceleration with that small adjustment

 

+2 degrees fine for 91 octane, or whats the best and safest timing?

 

i have a 2003 max with headers y pipe b pipe cat and megnaflow muffer with injen intake i just want to know what i should tell nissan on how to do this cause they said no one everyasked so i just want to tell them how to do it if u know how like to i say advance the timming by 2 and if they say it will reset after 300 miles is this true anything else i could tell these guys theve never met someone who likes to play with a maxima with mods lol thanx

 

I'm interested too. I've been wanting to advance mine for a while to 17. I'm in a small town and the nissan techs aren't quite up to speed. The more info I have the better I can explain it to them. They told me in the past it would reset itself.

 

I am very interested doing this mod to on my 5 gen. Looks like a good things to do. or may can be called best bang for the bucks.

 

That's what some Nissan dealerships told me too. People that have done this and are happy with it, what do you tell them to get this done? How much would it cost? Thanks

 

Cheap mod, I like it.

Pedro

 

So 17 is good for a 5.5 gen? I use 93 octane in FLA weather...

 

The 2000 FSM I had said spec was 15+/-2 degrees vs. the 2001-2003 FSMs that have 15+/-5.

Maybe 2000s have some kind of ECU limit.

 

I just called nissan dealer, and they will do it at about 2 hrs labor max. $84/hr. But still much cheaper than Y pipe. Guys do you have any info that it may reset by itself? and what is the major advantage if i set it to 17 degree to my 01 AE? or would 16 degree will be much better and safer?

 

OMG...that's a raping, it only takes 15mins, if that.

I'd get the ypipe FIRST.

 

Do not do it for 84/hr. Like Icey said, it takes 15 minutes max. Find another dealer that'll do it for free. Stupid stealership.

 

OK I want to do this so I called dealerships in my area to get prices. The first one said you can't advance the timing cause there is no distributor (painfully obvious). I told him you could do it through Consult, he said no. Apparently he is not based in reality. The second one said the same thing about the distributor and then told me the consult would be 92 dollars if I was correct in saying it could be done. The third guy was a little smarter. HE explained that it can be done through the ECM but that the car would randomly reset it to spec (15). He also quoted me an hour (92 bucks) even though I mentioned it wouldnt take an hour. I don't know what to do.

 

i doubt the dealer would ever charge you exactly the time frame it would take to complete a job. They charge you the general price range of an estimated labor quote for whatever work you want.
