This is indeed a great tool.
I used it in my SPeed6 and loved the power gains and easy of use.

We've got these in stock ready to ship, and even have a few maps for the 370Z ready :)

^I thought there weren't any maps available yet?

yea what maps and gains do you have? im interested in this now that you said that...lol

We're emailing maps to all of our customers who purchase the Cobb AP from us. PM me for a price anyone whose serious about buying one.. I've got 4 in stock. I'll also beat any price on a COBB AP.. most/all vendors, websites sell for $695.00, but ours is much lower ;)

We've got basic bolt on maps for vehicles with the standard I/H/E combo. Working with a local tuner/dyno shop, we were able to utilize Cobb AccessTuner Race to develop some safe maps.

Gains were +9whp after tuning the AP (tuning off the base map). So we were able to extract some power from tuning. Maps are fresh and only have it on one local 370Z, and has been well over a month since we had it on the dyno/tune.

*edit on hp gains, my mistake! lol Also, we used AT Race, not Pro

I can't wait to see Denny's response. :stirthepot:

I'm speechless.

:icon18: :roflpuke2:

Speechless again.

Spent 3.5 hours on the dyno again this afternoon. Not sure if the dyno sheet will download as it's a larger BMP that's giving me a hard time converting to a smaller JPEG. However, the car AFTER TUNING made 330.3 hp and 262.2 (std). A gain of over 13 hp from last session.

Man, was getting a complex about the car being an underachiever. Lots of smack, with nothing to back it up so this helps.

Basically made too many changes to put my finger on exactly what helped the most:

Under drive pulley
Opened up the front bumper so more air reached the Gen 3 filters
Oil cooler (99% chance of nothing at all)
downloaded new Cobb software
55 degree weather

The bottom line is for a change and this is the real good news, the car actually seemed to respond to different input. Going to go way out on a limb and say Cobb made some improvements.

All except two runs were fine tweaking the fuel/air (still needs some) but on two other runs we tried adding two degrees in which the car lost power and on another we took out two degrees and the car lost power again. Could be coincidence or something could be actually happening timing wise. Need to review the logs to see what happened.

Brought in reinforcements to help tune the car from a buddy whom has done this for a living for ten years and together we are going to go a little deeper into the software. An old dog can learn new tricks and pulling out timing around peak torque is normal and he usually plays a lot with the timing in that range. The car is still pulling out some in that range and the general consensus was detonation. Need to log the knock sensors to see what they are doing but next session we are going to focus on details and timing issues.

No time now, but tomorrow I'll go through the logs trying to connect the dots to see if changes in the timing really actually affect what was going on or it was simple an accident. The fuel/air worked for sure!!

In reviewing the logs and dyno sheets from yesterday:


1. The AccessPort logged fuel/air ratio is a bit erratic below 4000 rpm, however pretty consistent above 4000 rpm logging consistently between .7 and .9 below the dyno 02 readings. Certainly wouldn't go by the numbers given by the Accessport until you do a similar type validation. Cobb said they would vary by given car but once a baseline is established, should be repeatable. Think .2 (factoring in the below scale variance) from the dyno is probably within limits of what a wideband 02 would vary from one run to another. Just remember mine was only consistant above 4000 rpm.

2. Running the dyno numbers into my average hp within usable powerband yielded a 9 hp average increase in 1st gear, 15 hp average increase in 2nd gear, 13 hp increase in 3rd gear and a 14 hp increase in 4th gear. Very usable power increase and overall a good dyno session.

3. The car has learned on top and between 7500 and 8000 the power curve has improved. Raising the rev limit to 8200 estimating output above 8000 rpm will yield a 2 hp average increase in 1st gear, 1 in 2nd, 1 in 3rd and 3 in 4th.

4. Changing the timing..... dunno? In reviewing the timing logs from my last (and best run) which I put the stock timing tables back in both of +2 degrees logs and -2 degree logs act like they did do something. The -2 did did pull timing out in certain areas but increased slightly in the midrange. The +2 added timing below but lost it all plus some on top.

Need to schedule another dyno session as my thought process is by leaning the car out it's going into detonation in the midrange and pulling out timing may actually increase power/timing in that area.

5. Even though disappointed with the limited amount of points to change the fuel/air programming, the readout is quite linear indicating no need to go into the MAF for fine tuning

6. The fuel/air from last session was quite a bit leaner. The person helping me tune said I'd probably need more fuel than expected as more and more gas stations are going to 10% ethanol. Hard to say, but that could have been the case so ending up adding quite a bit of fuel. The car seems to like around 12.8 to 1 the best.

7. MAF A and B voltage on the logs indicate one side is getting more air than the other plus A and B calibration scales vary from side to side. Need to mull this over with my tuning buddy as he really knows quite a bit more but my thoughts are the factory has compensated for the factory intake. Now that table needs to be tweaked for the Gen 3 intake. Any thoughts?

8. Non-linear tachometer. For some reason I've felt a disconnect with the tack and the person driving my car on the dyno is an old salty mechanic and drag racer. He also noticed the tack seemed to speed up at times and lag at times. This was unsolicited and surprised me as I couldn't quite get my thumb of the tack. It's also reads 200 rpm higher.

Bottom line....... Think the AccessPort is working better. Don't take it to the bank as a little more experimentation needs to be done but finally think there might be a little light at the end of the tunnel.

Ain't this a bitch...something good happened for a change. What's up wud dis?

forget to mention to try running some race gas and see if it is pulling the timing out based on knock and switching maps on you or if it is some paramater that is doing it even before knock. Just a thought

Nice write up on the dyno session notes.

I called COBB again and they have no new updates as of yet.

I wonder if it might help them to get a Nismo 370Z and compare that ECU to the stock one, to see what Nissan changed to optimize the performance for the Nismo exhaust. Who knows, maybe that will give them a clue as to how to tune the VVEL system (that's assuming Nissan made changes to the VVEL map for the Nismo edition).

Is anyone else here like me and just waiting for them to come out with the base maps and officially support the 370Z before they get a tune?

I am too. I used to have one on my WRX and loved it but never did anything other than the Cobb maps. No one in my area does pro-tunning and I'm not horespower hungry enough to drive to a pro-tunner. Hopefully Cobb comes out with some basic maps soon enough.

I keep requesting updates on the COBB forum but I always get the "still working on it" reply. I am starting to loose patients waiting for them to release the maps.

Emailed three times and yet to get a response from COBB...?
Anyone on here used the race tuner as yet on the Z?

I have experience with the COBB software on other platforms, may just bite the bullett and go it alone, I need the software anyway with a flashing device but wanted an opinion from some one before dropping the bucks.

If anyone has a NISMO rom - send it to COBB ;-)

Update - heard back form COBB - stil no definitive uodate.. lol

Damn how many people have died?

^ lol!!

Dont think they are going to release the stage maps with out first unlocking all the definitions to open all the tables etc, cam timing,blah blah , they would just have to re release there stage maps.
I would already have there software if the full array of variables had already been accessed ;-) it does suck but who can put a time frame on correct development and testing.
I like to know when I make an adjustment in the rom it is adjusting exactly what I think it is lol

So, for the money, would you say that the AccessPort is worth it. even if you don't plan on getting in Dyno Tuned for a while?

^ personally to me it is worth it as I like to tune. If some one wants a one off flash, there are cheaper options, horses for courses dude.

If you get one of the calibrated roms when released your car 'should' run smoother,quicker etc, they will prolly develop rev2,3,4, files that you can download for free.
Apart from the flashing the AP is a usefull tool, also with datalogging you can monitor your vehicle closely if you so wish, I personally like the ease of install - deinstall.
695 I feel is not a bad price as there are no freeware options.

On other platforms you can set your self up to tune and log for a couple hundread bucks, free software so the price of the canbus/OBD11 cable is all you pay, now that was nice and a no brainer in terms of $$'s

+1 I totally agree

Without a doubt YES!!

It is a very advanced piece of equipment. We've been lucky enough to be involved with the development/evolution of the GT-R and 370Z AP software (from a R&D/testing standpoint). The AP is powerful - as the software advances so too will the vehicle control. Not only is it worth it for NA, but it will take you the distance for F/I - we've made 500+whp with the 370Z, and so far over 700+whp for the GT-R and the COBB has worked as flawless as one would expect.

If you are not interested in the current COBBs MAPS, we sell the COBB AP at its regular price with our basic AAM MAP uploaded for free.

Even if you are not dyno tuning, you always have the option of data logging. Since you are driving your vehicle no the street 99% of the time anyway, e-tunes through datalog analysis prove to be a very effective tool for optimizing your current set-up. Its not quite to the level of having someone spend a day with your vehicle, but it is certainly the next best thing.

Feel free to hit me up if you have any specific questions.

Too AAM - Is the tune you provide for a 100% stock car or is it with mods? If with mods, what ones?

Can you give me some info on the AAM basic map for the AP. Is it for a stock Z or one with mods?

^^ Absolutely. Sorry about the delayed response. PRI threw a wrench in things around here.

For the basic map, you tell us what mods you have, and just like we do with our flash for the 350z, and we will optimize your particular set-up (also taking into consideration location and octane.) This we are offering as a free service with the purchase of a COBB AP

From there, we can step up to an e-tune. We'll still start with a map based off of your set-up. However, we'll analyze your data log files across a broad range of driving conditions and make the appropriate changes.

I still need to get some graphs up for you guys. We're also going to be officially releasing the various stages of our TT kit shortly, and we'll be running a special/info thread on our 3" and 2.5" TD exhausts. So when I get in tomorrow morning I'll spend the day on here and focus on getting back to everyone. And I will get into more specifics.

And to those whom PMd me, I'll hit you back asap!

Regards,
Clint

Great deal via web page

I'd like to hear the specifics...

Coming from Hawaii, to have a local tuner is a plus and can help on which brand of tuner to get. Locally we have someone that can tune on their dyno with the REV tuner,.. I dont plan to go wild, but this would be the best setup since I would want a tune "specific" for my car and not off the shelf type map, and to turn off my TPMS error since I got aftermarket Volks on..

Cobb is great as I do have a Subaru Legacy GT, but I have to wait till Jarrad of PDX to come to Hawaii to tune to the mods that I have. Doing a dyno tune is the only way to get the most out of your car with your specific mods...

Currently I have a FI Carbon Fiber catback, Injen CAI, and FI high flow (yet to be installed) cats to put in and will want a tune to get the most from my mods. Tuning helped my gas mileage on my Subaru (from 15 to ~17 - 18 mpgs) and running close to 400/400 at the crank on a 16g turbo on the street that is a DD...

Just an update for those following this thread:

Joe from COBB said this...

"Yes we are still working on it. I've got a 2010 Rom to add to the firmware, but we are still working on the VVEL system. In order to produce 'caned' maps we need to be able to tune the VVEL. Thats were the extra power is on these cars."

This is great news!!!

I just wanted to let you guys know that we have dropped the price on the AccessPORT. All models have had the price reduced, however, the new price for all Nissan/Infinity models (less the GT-R) is $495!

We are continuing to develop the 370Z platform and we will continue to bring new features online as time goes on.

NISMO tune?

Vipor:

You are alwasy one step ahead of me.

Cobb:

I emailed you guys via your website about NISMO Z support. Are we good or waiting for firmware?

We are discussing this now. It is in the works and should be ready once we are finished with testing etc. However, we do not have stage maps ready, only tuning support at this time.

Can't wait :tup: :excited:

Heck yeah. I gotta get hooked up with some TT awesome-ness and Cobb AP looks like the way to go. If it's not ready (I.E. bug free and full production) by July, then I have to wait until October/November. That just means more time to save for goodies...................:ughdance:

so this might be a stoopid question but does this just come with a base tune or what? I guess to be more specific, I remember (I think I remember) Sharif@forged? or one of the major tuners saying that when you buy from them they will help out with tuning down the road after some data logging is done and you tell them what aftermarket performance stuff you have.....something like this?

lol this post doesn't make since I don't think... Can someone please help a dumbass out and explain to me what my options are as far as the tune goes? Like who to buy from and what you get when you buy from that particular company?

Cobb is selling the Access Port for the 307z but it doesnt come with any pre-loaded maps. Your local tuner (if they can do Cobb AP Tuning) can tune the car then use the AP you bought to load the map on your car.

To make a long story short...cobb has been taking god aweful long to figure out the VVL tuning piece which until they do they will not release any pre-loaded maps.

I used Cobb on my STi...it was awesome. The wait for them to release maps for the Z...not so awesome.

well the Z is so much better than an STI so it could take time at least they haven't given us a big foot up the @$$ when it comes to the VVEL like some people we know. My cars in a garage until march so i don't care either way but it better F***ING be done before APRIL.

New price for AP - pretty nice

I've added support for the NISMO Z, and crated some very basic maps. Sorry no staged maps yet. I'm going to flash our 370Z to be a NISMO and make sure everything works.

email me if you are waiting for it.
