I was at a local dealership today and I talked to a mechanic about advancing my timing 3 degrees (to 17btdc). The mechanic said he could do it with their Consult II for $45, but he wasn’t sure if it would stay at 17btdc. He said it might go down after a while. Also, he said my car might ping. From what I’ve read it seems to stay set at 17btdc so I’m not to worried but the mechanic had one important question.

He wants to know if he needs to reset the “Self Learn” function. I showed him the Target ignition timing adjustment sheet from THIS link (he knew exactly what it was and how to change it) but he said he didn’t know if he should reset the self learn, which is in a different section under “Work Support”. So do I need to reset that or should I leave it alone?

 

No. He is worried about the Idle Air Volume Learing procedure. However, it appears to not be necessary unless you go 18 degrees or higher.

If he is willing to perform the Idle Air Volume Learning procedure at 17-degrees for the $45, then you should have him ATTEMPT to go to 18-20 degrees just to see if it's possible.

He can ALWAYS change it back to 17 once he is done. Good luck!

 

Thanks for the info! Is 17-20 still within specifications? In the post where you explain the idle air volume learing you said it was 15 +/- 5 but I recall reading it was 15 +/- 2 somewhere (cant find the thread). My car is a 2k auto and its cali spec. (if that makes a differance). Also, has anyone done this yet? Is there a chance of damaging anything by putting it too high?

 

The timing advance range for 2K Maximas is 15 degrees plus or minus 2 degrees BTDC. I would not recommend that you attempt to advance your timing beyond factory spec.

 

This coming from a guy running 235s on stock rims. Don't you know that's dangerous!

 

what does this mod do?

 

The '02 ECU won't go past 17°, I know because we (Nissan tech and I) tried.

 

I still haven't advanced my timing on my 2k3 yet..

Touche, Max_Gator.

My reasoning has to do with possible warranty issues if anything goes wrong with the engine. Obviously, Nissan cannot void your warranty if your timing advance is set within factory spec. But if it's not . . .

 

Thanks, I though I read that somewhere. I'll advance the timing to 17 btdc when i go and let you guys know what i think.


Igor911,
Timing advance is supposed to improve your midrange (2500-4000). A bunch people have done this and said they felt a differance so i though i would give it a try.

 

I have a 2k GLE with timing advanced to 17 BTDC. It definintely feels like there is more pickup and pull through the mid-range and high-range RPM's. Most people who have done this can attest to that. For a $40-45 mod it's I believe its worth it.

 

Hey does anyone know of a shop (not a dealership) in the Los Angeles area with a Consult II? I want to avoid a dealership if possible but i doubt anyone has a consult II outside of nissan.

 

Finding a shop with a Consult II outside of a dealer is a pretty tough find. I just went to the dealer by my work. The service advisor was actually really cool with it, he didn't give me any flack about it at all. He used to be a tech in that same dealership so he probably knew exactly what I was talking about.

You should call different dealers in your area and see what kind of resistance if any that you get. Just tell them you want to advance the timing and see what their reaction is.

I did get some negative feedback from one dealer near my house. It was 3:40PM and I told them I wanted the timing advanced. The guy straight up said he didn't have time and I explained it was only a 20-30 minute job. Their service bays were pretty much empty too. He just kept saying no, but oh well it could have been that he wanted to go home right at 4...lazy. Oh well...

 

Heh, my service advisor was such a moron. He tried to tell me that it was preset and impossible change. I bypassed his stupid a$s by going to the parts department and asking to speek with a mechanic about it. The guy in parts and the mechanic were cool.

 

Went to get it done just now, but the compitent mechanic i talked to wasnt there today. Looks like it wont happen til next week.

 

I'm just pulling your leg . . . of course, I have 225s!! LOL.

I agree with you on advancing beyond 17 for a 2k.

I wonder though, assuming it is possible to advance beyond that through the idle relearn, is there a device that would allow you to see if you are getting knock - since you can't always hear it?

 

If you keep getting the runaround, call Henry Perez in the Service Department at Performance Nissan, Duarte, CA. Tell him you want your timing advanced to 17 degrees BTDC. Tell him Bruce sent you. Your cost should be $40.00.

Henry can be reached at 626-305-3000.

 

Cali spec 2000 and ALL 2001 are 15 +/- 5. Why fed spec 2000s are 17+/-2, I have no idea.

20-degrees is possible, you just need to perform the PROPER procedure. 17 vs. 20 will probably not make much difference, but until someone actually dynos this mod, we don't even know if 14/15 vs. 17 does anything FOR SURE.

Butt dynos are like azzholes, everyones got one.

 

Hmmm.......I dont have a dyno at my shop I eventually will, but not now, they dont exactly come cheap. I know u didnt mean a dyno in that way Ice, im just bored.

 

 

Yeah I know

 

BTW, what shop and you got hookups?

 

The 1 that I work at check ur PM in a few min.

 

LOL! I love it!
