Whelp, I finally did it and without the help of a dealer or consult-II

I found that my Autoenginuity ODB-II program has a neat manufacturer specific upgrade, which in Nissans allows factory only functions such as idle target adjustment, timing adjustment, and idle air re-learn (and monitoring of practically all the ECU readings). The tool paid for itself over time as i've used it on many vehicles.

So after driving around for a year looking at my stupid Blitz R-VIT meter read 15 degrees base timing everyday, I bought the upgrade and 5 minutes later...



Then I did the idle air re-learn (although the car didn't react different after the timing adjustment)



Just thought i'd share For anyone that wants to know what the tool can do:
Nissans (functions depend on year and model)

Other cars

Oh btw, the clock time is earlier on the idle air because I was just testing to see if it worked first before trying the ignition timing.

 

interesting....

 

Hmmm...interesting, so when can we try that on my Max?

 

soo larry.. can i go to LA and you do that to my car?

 

did you try going higher? maybe you can go higher with that thing and see where you can get to

 

Definitely interested and looking to buy this sometime... next year. Doh.

 

how much is the whole program and what device are you using it with and how much is that device

You check out the price from the link I posted in the 1st post. The price is determined by which system you want and options.

A33: yea, I can do it on your car when you come down. Gotta hook up a past customer

Foodmanry: we can do it the next time we meet up.

Hoooper: just like the Consult-II, you can also advance base timing permanently +2 or -2 degrees. Originally at 15 degrees, +2 correction = 17 degree base timing.

 

What's the sampling rate?

 

Quick question for my friend that owns a Spec-V, can this program edit the Rev Limiter?

 

uprev cipher has the same features. Very cool

 

I don't even think the consult-II can alter the rev-limiter on a Spec-V. It may require some sort of reflash from a company such as Technosquare

The sampling rate is unknown. All it says is 1ms logging accuracy. Its not super great when datalogging, but it gets the job done. Sometimes you pick up random numbers that have to be manually deleted in the excel spreadsheet. It doesn't sample too well during throttle blips in idle (but I like to think that's because my car revs very fast with the lightweight stuff )

 

Did you get my email?

 

replied....

 

OK why do you advance timming

 

google is your friend

Difference almost un noticeable. All it does IMO is just makes VQ smoother.

 

Did you do this with the ignition on only or does the engine need to be running while you adjust timing

 

Personally...based on my experience with my 5th gen I've seen that advancing the timing actually helps with gas mileage. When I had my timing at 17* I saw about 25MPG city and highway with an auto tranny. Now after setting it back to stock at 15* I'm getting about 20 to 21 MPG city/highway. I did notice when I had it at 17* my plugs would burn out faster because of the leanness.

As far as performance I really didn't notice much....only reason I want to go back to 17* is for the MPG.

 

Engine needs to be on and warmed up, otherwise the procedure won't work

 

Just for everyone's info, the timing isn't advance passed 2300 RPM when using this method.

 

my question was can you get it to go more than two degrees?

 

You can advance it +2 or -2 degrees, just like the consult-II. In short, NO.
