I just find it hard to understand why Nissan wouldn't have advanced the timing 2 degrees if it improves response and hp, especially if you can still run 87 octane. What possibly could be their reasoning for that?
Improved performance and hp from 2 degree timing advance?

There is some confusion here regarding timing issues. When the knock sensor retards timing it does not change the base initial advance. The timing on the Titan is constantly changing depending on load conditions. The purpose of the knock sensor is to pull timing back when it "hears" the slightest ping or detonation (we will not hear this).Titan1219 said:

The person I know that did the advance timing was/is a Nissan tech, and had no issues with his timing.
I remember someone saying advancing the timing allows the truck to make up for all the electrical components it's running-if I said that right. Other have said it helps with the hesitation issue under WOT from a stop.
So, if I can help my truck by doing it, then I'm going for it!!!
Do I expect to break in to 14's because of it-NO. But what can it hurt at this point.

Hey Sobe, that 5 hp gain was on 87 octane or 91?

Too much advance isn't always better. You probably would start to lose some upper end.Titan1219 said:

It won't go four. The most anyone's been able to get it to stay has been 2. Will need to crack the ECU (I think) to get beyond 2. But there's probably not additional benefit. Most will handle two without changing to a higher grade fuel.
I might be wrong, but isn't that the difference between the Nissan and the Inifinti-advanced timing and higher octane fuel. Otherwise, it's the same motor..??

Hey Guys I ran some 0-60on Wed/Thursday using Cipher to log the data and time the run.
Test proceedure:
2 runs each direction back to back after the drive home from work. I ran +2, 0, -2
First of all I want to determine:
1. Does indeed without a doubt +2/-2 timing stick through the rpm range when using Cipher.
2. Do my times suffer?
3. What effect does 87 vs 93 have?
First question please....
The answer is YES without a doubt there is timing through the rpm range as it should after adjustment.
Second Question:
No times are as expected with increased timing there was shorter ET's.
The best of 2 using 50/50 blend of 87/93 octane:
+2 at 7.20sec
0 at 7.50sec
-2 at 7.76sec
Third question:
I saw slightly richer ratios with the 93 octane according to Cipher. I saw a better 0-60 ET 93blend 7.20sec 0-60 vs 7.32sec with 87. I also saw higher RPM and 1 degree more timing at 5500. However when averaging the timing column from both fuels they were nearly identical.
Disclaimer:
These tests are for the performance minded Titan owners that understand that a Hemi with bukoo bolts ons is faster...LOL

I got this done yesterday for free at a local dealerhip, and the butt dyno tells me it has more grunt in the low end.
I was leaving downtown getting on I-10, and there is a light that leads straight on to the highway. Light turned green, and I punched it to about 70. I could feel a difference in the way it jumped off the line more than anything.

Initial Timing is the ignition spark timing set at idle and with the transmission in Park. It affects performance such as acceleration and fuel economy and horse power.

Why trust the Dealer, when you could have someone you trust do it and have fun meeting other Titan owners?import2nr said:

i get what your saying but i just dont want to spend 140 or so bucks on gas if the cost of doing it is only 30 or 40 or 50 or 70 bucks... plus i have a pregnant wife (of 8 weeks)and a 15 month old son who would come with so i wouldnt look forward to the DRIVE down there.SOCALTITANKC4X4LE said:
