Just wanted to share a positive review with the AccessPort for the 996TT.

A little background, I am in the Cobb Protuner network with Subaru and have 10 years of experience on the that platform, so I knew the AccessTuner software going into things. When I heard they were coming out with the 996TT support, I was really excited as I own a 996TT and I love driving and maintaining it.

Simply put, Cobb has done a really nice job with the integration into the 996 TT ECU. The table definitions are strong, well-documented, and precise. Admittedly my car is not too wild.... just K16/24, 5bar FPR, EVOMS intake, GT2RS ICs, Fabspeed exhaust, and some other goodies like silicone hoses and F-pipe, Forge diverters, etc. With the AccessPort and the Porsche ATP software it was a cinch to get the car running butter smooth and better than it has in a long while. I initially ran the first flash in MAF mode to get a sense for things, but immediately toggled MAFless mode and began work that way... it's the way to go on these cars that love to burn up expensive MAF sensors (already 2 for me in only 10k miles!). The MAFless implementation is very well built and has been a treat to work with and dial in on my setup so far.

The AccessPort handheld unit also works well, with excellent polling speed on the 6 viewable gauges and the data logging parameters are well-configured right out of the box. Flash speed was excellent too.

In the coming days and weeks I'll finish up my mapping on the road and hone it in on the dyno, then simply enjoy the car. If you are shopping tuning solutions I would not hesitate to look at Cobb's product. SamboTT is a great vendor on this website I know off the top of my head, and Cobb's site has a network of protuners you can search through. Side note: this isn't a personal advertisement, I only use the software for my own vehicle and my own personal use. This is just a review of the AccessPort and its integration to our cars!

Thanks,
Ben

 

Nice review. I'm seriously considering Cobb AP for mine as well. It seems like a total no brainer. You get the tune, the device to switch around tunes, plus data logging. I do have a Durametric but this is just so much slicker! Good stuff.

 

Just installed my Cobb yesterday. Impressed with the interface so far, but have not driven it on the OTS tune yet due to snow.

For those running Cobb, which parameters do you use for the 6 gauges? Assuming you run 6 gauges that is. On that note, any thoughts on running 4 or less gauges. In that case, which ones do you log.

I currently have AIT, Engine temp, Oil temp, boost, AFR, and volts. Open to suggestions.

Sorry for the thread jack.

 

The live gauges are only for driver info. The data logging parameters are done separately in the setup screen accessible from the live gauge view.

Which ones you choose are up to you. I have my 6 gauge layout set up to monitor individual cylinder knock levels. The 5 gauge layout is for every day driving, with boost, coolant temp, oil temp, bank1 lambda and intake air temp but I will end up shuffling it based on what I'm working on.

for data logging you can use the defaults but your tuner will likely request you alter them a bit (I tweaked them slightly).

 

anyone found a good permanent mounting spot in car for this?

 

Just to the left side off the windshield. Mounted on an iphone 5 RAM mount that's been modified to fit the COBB magnetic slide/receiver. Works amazing and doesn't move at all. Wire is run through the void in the dash over the steering column and comes back out underneath to go into the OBD port.

 

I run AIT, engine temp, oil temp, boost, AFR and one other that I can't recall from memory. But I rarely use the AccessPort, as the Sambo tune is consistent as hell and I've not changed anything in quite some time.

 

Awesome bud! And I love you guys too!

 

Definetly a good upgrade!

 

I have the COBB AP running OTS stage 2.

Can you talk more about MAF/MAFless - what's involved from a hardware perspective? it requires a custom tune I assume? Are there power gains over MAF?

Appreciate it,
Kevin

 

New to porsche
do cobb tuning come with different setting for say low and low octane fuel and / or tuning setting for stock/ stage 1 / stage 2 tts?
thx

 

In the States, the Cobb Access Port ships with maps for both 91 Octane and 93 Octane fuel. Tuners like Sam can create custom maps for higher octane.

For example, I have a map for 95 octane (half tank of 91, half tank of 100) and a map for straight 100 octane. I can change the maps in a few minutes.

There's also maps for stage 0 (stock), stage 1, and stage 2.

 

No hardware changes necessary. Just unplug the MAF. I removed it from the intake piping and made a block off plate from sheet aluminum to plug the hole where the MAF came from.

Talk to Sam@ ByDesign.. He can explain it to you, it works brilliantly. Removing the MAF from the airflow may add a little power, but I think the gains come in the tune and the fact that you no longer have to worry about MAF failures which seem to become more prevalent on modded cars.

I went from an off-the-shelf 91 oct map to a MAFless 92 oct custom map, and the car runs noticeably smoother and when I logged acceleration times, it is a over a full second quicker from 60-100.

I think Sam mentioned you when we were talking and he made my tunes... He gave me a 92 oct tune, a 100 oct tune, and then what he calls a spicy tune for the 94-98 octane range;he said you were very happy with the results on yours.

I'm finally getting some good gas in it to try the spicy tune this weekend, I can't wait

 

Yep, I have the original spicy MAFless tune...works very well, But given that I don't have much time to drive my car, I decided to go ahead and just run straight 100 unleaded, well, because I can. The results are impressive...esp. the midrange torque. My vision for my 996 Turbo was always a lightly modded race gas swilling hot rod. It totally lives up to the expectation!

 

100 oct isn't readily available near me.. I don't drive the car super often otherwise I'd do the same. So 100 oct is a noticeable jump from the spicy tune?

I'm going to be using a product the GTR guys and a couple of other friends run Torco accelerator "race gas concentrate". Tested and proven to actually raise pump gas to almost race gas levels. Hopefully works as good for me as it does for those guys. If not I'll have to start buying drums of 100 oct
