How about a refund? Bought mine almost a year ago and in disguest, unloaded my $$ dyno tuning programming converting the ECU back to stock.

Finally figured out why the car got such poor gas mileage...... It's the AccessPort. Not really one that into gas millage, but on a trip noticed the car was getting less than 19 mpg on the hwy doing 85-90. OK, me driving fast. By happenstance, the AccessPort was in the car and used it for something it actually kinda does do (even though it's not accurate)...... read the 02 settings. They were pig rich. Pulled over, downloaded the stock tune and the car jumped 4-4.5 mpg better still driving the same speed with normal looking 02 readings.

Kept the stock tune in the car for a while and tried downloading a newer version hoping the bug was fixed. Reprogrammed the ECU and this time doing a road trip to a seminar down in Houston. Same story..... The Accessport negatively effects gas mileage causing the car to run pig rich. How much additional wear does this put on the cylinder walls and rings Travis? Guessing a fair amount as it's washing the lubrication away.

The bottom line is between poor quality from Stillen, things that don't work like the Accessport and grossly over rated items like the Stillen headers, I'm selling the car.

What kind of fun is this when expensive items that are suppose to work...don't.

Refund?? I'll gladly take one and forget about all the dyno time money I spent.

No offense, but your car should not be running that badly, the person who did your tune is to blame not Cobb (unless you went directly to Cobb to have your car tuned).

Cobb in Plano Tx did the original tune and I tweaked it on three dyno tuning occasions after finding the car was pulling out timing and tried to correct the Cobb tune.

No offense back, but you need to learn how tuning software should work. Changing the fuel/air ratio to optimal during acceleration has no effect on driving fuel tables with other software I've used like LT1.edit and HP Tuner. Your tweaking apples and oranges. The computer is suppose to be looking for certain air/fuel ratios and correcting itself to them. Obviously this is not working correctly with the AccessPort.

I know how dyno tuning works, but they are not just suppose to tune top end power only. They should be doing different pulls, tuning all sides of the car, performance, cruising, etc. You mentioned you made your own edits, was this before or after you were having bad MPG?

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...................

StillenZ · 02-02-2010, 05:06 PM

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.

1slow370 · 02-03-2010, 03:26 AM

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.

Kastley85891 · 02-03-2010, 08:55 AM

New price for AP - pretty nice

theDreamer · 02-04-2010, 11:54 AM

I want to ask, since everyone mentions this as the big item to do, but what exactly will be seeing if/when VVEL is unlocked? What is holding it from being unlocked, just allow the system to let you adjust the VVEL system?

email me if you are waiting for it.

Theoretically, if you can adjust the VVEL, then it'll be just like getting a new cam

1slow370 · 02-04-2010, 02:26 PM

You would also be able to adjust the cam timing as well so you could reduce overlap for F/I.

KEVTEX · 02-04-2010, 05:36 PM

Remember the VVEL only affects the intake cam, not the exhaust cam. To get the maximum benefit from VVEL tuning you would also have to tighten the fulcrum screws to increase the maximum intake cam lift from .450" to .500". Duration would increase from 280 to 300 degrees.

ZKindaGuy · 02-04-2010, 08:29 PM

How long is it going to take Cobb to get the damn canned maps done? They have been working on these things for almost a year now. All I keep seeing in the advertisements is that the maps will be coming soon. What decade is soon? Are they waiting to see if the world makes it through 2012 or what?

Hey Cobb, produce the damn maps or
