Just received my Accessport!

Basically - Ability to control lift, advance and retard of cam shafts

More air in, quicker air out coupled with a retune of fueling and timing should make for decent gains.

FI equipped vehicles will be able to retune to be quite a different 'feel'

Thanks, exactly what I wanted - a few sentences dummied down.
Could such a thing have adverse effects on the engine? I mean just messing with A/F ratio seems harmless enough within reason, but this starts getting a little more complex.

Kastley85891 · 05-27-2010, 07:28 PM

Sure it can man, you need to know what you are doing, any variable with in your ECU can seriously F you up.
A decent tuner will be able to get teh best from your set up, variable Cam timing is nothing new, but it is un known presently how the VQ platform will react short term or long term, guess we will find out.
In short though too much advance will bog you down, mess your fueling and your timing, screw with your EGT's etc etc, too much retard will not allow enough air flow and can cause a slow revving sluggish top end, you get the picture? as with evrything, all about balance.

I'd like to thank everyone for their AP orders!

bumblez · 06-02-2010, 09:19 PM

I just got mine today. While I was installing it, screen says This version of AP does not support this vehicle. So I couldn't install it. Does it matter if I have 2010 ECU??? My dealer had swap 09 ECU model to 10 ECU model because of the high pitch noise.

Kastley85891 · 06-02-2010, 09:33 PM

Ya it matters dude, you need to pull that rom file with your AP and send it off to COBB to get it added to their 2010 release when it comes.
Although it wont install, you can pull the stock file from the ECU

OOI who here is running an AAM AP tune on a stock Z?

bumblez · 06-02-2010, 09:37 PM

Omg!!!

So basically, 2009 and 2010 model use different firmware? Or different version of AP? If the only difference is firmware, better wait till they relase the firmware for 2010 model? Or I should return this. I searched a lot before I placed the order. But I couldn't find that 2010 model not work with this version of ap.

neway... I called Cobb support center and the Nissan programer will give answer tomorrow...

Kastley85891 · 06-03-2010, 07:30 AM

Keep a hold of it, it happened to me on my 09, it was over Xmas break lol COBB sorted it for me NP. Its the same AP but it does not recognise the ECU id that is all.
Z is still relatively new and the new releases of ECU handles need to be incorperated to the 'accepted' database for the AP to see it and know it is able to install.

This will help

So is the consensus to hold out on buying one of these until they crack vvel?

Snakes709 · 06-14-2010, 08:50 PM

Made a thread in this section but no one answerd, hopefully it can get answerd here. As it says in my sig, i have a 100shot of nitrous set up. I'm going to be buying Cobb AP, how hard is it for a average joe to take of timing retard off the tune? Or it REALLY required to be done by a pro. I have no intentions at adjusting the rest of the tune on my own. All i need to do is take a few degree's of timing off just to test my system out, then go get a proper tune.

Kastley85891 · 06-14-2010, 09:01 PM

Buy your AP, download the software and take a look, it aint that tough
