how tunable is Cobb's AccessPORT?

[F2T guy]

just as the title states I want to know how the Accessport compares to a standalone or even a glorified piggyback as fas as ability to modify parameters and to achieve a tune that best suits your setup.

does it work for both lightly modded setups (example: SRI + a downpipe) looking for a slight bump in power, all the way to a far more aggressive custom fuel, forged internal, GT35r type of setup capable of 500whp?

where does it reach its limitations, what are its limitations, and is this a good investment for someone who wants to start with a lighter modded setup but can retain the AP's tuning capabilities if they decide to go with something more aggressive? (the 500whp mark is just an example not an actual # Im looking to acheive)

The COBB AP plus their free ATR download should be able to take care of all of your needs from just a SRI up to a BT setup. If you feel comfortable messing with the tune yourself, you can make the tune do pretty much whatever you want. It's a good product to pick up IMO.

It will tune everything.

1st, there is no standalone system out for the DISI; so you're only options are going to be piggyback units. 2nd, from what I've read, if you want real power, you're better off going with the CPE standback. The AP is good for minor tuning, but once you add a big turbo, internals, etc, the AP is limited, and the standback appears to be the better option. There's a reason you can find AP's all over the FS section. Keep in mind, I can't speak from experience, only from what I've read. I'd recommend doing the research and read up on it before you decide.

I'm not 100% on this, but when I was researching them to decide which to go with I read somewhere that the StandBack just manipulates what the ECU is seeing rather than actually changing the tables themselves, which is what the AP does.

Honestly, though, someone with more experience with the StandBack unit should chime in and correct or confirm that, because I don't remember 100%

I am not saying you're wrong or right as I don't have a ton of time using the COBB ATR program but I think even going with a BT setup the COBB AP should be able to tune pretty well. I could be wrong though. Either way, the AP or SB are great options!

 

[bradboyd80]

Hell, even I wasnt saying I was right or wrong. LOL. Just relaying what I've read. Maybe I don't look around enough, but I do notice 2 things: A) I rarely see any standbacks on the FS forums, yet there's always 2 or 3 AP's out there. B) All the high hp MS3's I've come across are running SB; not the AP.

Again, that's just from what I've seen!!! Could be simple coincidence, I dont know. Maybe someone with the SB will chime in though.

Now they can.

"COBB Tuning continues to push the envelope in stock ECU engine management control by removing the ?load cap? that has prevented enthusiasts from achieving maximum gains from larger than stock turbochargers. Through ongoing ECU discovery, software development and internal and external testing, COBB Tuning has created a tunable solution to alter the load cap parameters, allowing Professional and Enthusiast tuners to break through the 400whp barrier within the stock ECU!" - COBB TUNING

and all this can be achieved with the accessport?

 

[hugador]

Yes, just download the new version ATR and you're good to go.

The Standback is a "piggy back" system that always needs to be connected to the car. It intercepts signals and modifies them. The AP is a flasher and you can use "off the shelf" maps or tweak your own at home with ATR before flashing the map to the ECU. Once the map is flashed, you can unplug the AP and leave it at home, although most of us use it as a monitoring/logging device, like a Dashhawk. It only displays one parameter at a time, but can log everything.

You've explained correctly. The feature in AP is what I like the most, the standback is a must have.
