Cobb acc port
I am looking for anyone who has tuned there 350z de motor with the accessport. I need to see some of the information with in the correction tables, you can do this by loading the access tunner race free software. Then plug in your accessport to download the tuned map. Any questions pm me.
I Knew i should have put the "Dont say get osiris disclamier in my post". Thanks for the advice, but that doesn't help me very much.

if you wait till Nov i will post my results... i am tunning with the cobb due to emission problems in CT, Standalone ECU= Automatic failure. Car will be running 18 psi from powerlab turbo kit. i will post the charts and tables if you can wait that long. I have a friend who has a 03 base with aps ST and cobb access-port was used to tune, i will try to get the tables...i wouldn't hold my breath tho
i have an 04 base z and i have the cobb tuning installed at stage2+ i have full bolt-ons it ok i guess for a n/a setup i have a another friend with a turboxs utec and he loves it my z had a couple of codes come for emissions so my car is running a bit rich but all in all its a safe tune when you download from their website.

The Pro tuner race software runs on a laptop. You are plugged into the dongle from your accessport. I've got the instruction sheet if you're interested in reading through it.
ThreeFiddyZee.... i would like to take a look at the sheet if its not to much trouble... (if you have to email me its John.brubaker23@comcast.net ) and with this update... would you say the accessport is as powerful as osiris???

). Haven't to try it out lately. I'm a complete noob to tuning so I needed to do a lot of reading first. Emailed the help file.
We have detailed tuning instructions posted on our forums. Just go to www.cobbforums.com and you can download the tuning guide for free. AccessTUNER Race is available on our website, just follow the links on our website www.cobbtuning.com.

Sorry for the delay guys, the answer is yes, i have used the tuner software. First starting with a base stage 2+ map, (do to my full bolt on mods) then spent some time talking to the guys over at cobb and did some datalog runs. I was running lean as expected though stage 2+ map was good made changes to the mass air flow calibration as per my logs. The gains from just calibrations were deffinitely felt. I will do some changes now to the air fuel targets seeing how i am runnin 93 octane and try and tune for 12.6 t0 12.90 air fuel ratios. Travis any help or suggestions would be greatly appreciated.
Sorry guys, we have been away from the boards over the holiday weekend. I will forward this on to one of our tuners and have them reply as I myself am not a tuner. Thanks for your patience.

HI Guys,
This is Tim Bailey of COBB. I understand you are tuning a forced induction 350z. What kind of issues can i help you resolve using our software? I assume the injectors are larger and you are using a fuel pump. Please fill me in on where you're at with the tune. Also, what kind of intake are you using. Its important for you not to saturate the MAF sensor with a forced induction application. If the MAF sensor is saturated you'll need to source a different (larger) maf housing.
Generically speaking, Osiris and accesstuner have exactly the same tuning capabilities. Both products allow changes in the stock ECU calibrations. Its the same ECU, same tables, same logic, etc.
Regards
Tim

I have a quick question.....can you data log your mas values and then go ahead and plug them into the mas table. I know you will have to smooth the curve out, but is that the way to adjust the table with direct values obtained from data loggin @ 100% throttle ??
Subbin since I got my AP today 
The Cobb forums in the Nissan section is quite dead honestly. So lets hope we build a nice knowledge base here. Im just waiting on my download key for the race software to try my hands at the tuning section.

I just got my car Cobb tuned last week. My results were pretty satisfying. I gained about +10 whp throughout the powerband and peak torque of +20 wtrq. I have full bolt-ons with the stage 2+ map flashed and dyno-tuned.
