Accessport Questions

[cageyvet]

1. Can you manually adjust your boost pressure with the access port or is boost pressure delegated by maps and custom tunes with access tuner software?
2. If you can't manually adjust access port boost pressure can you use a MBC in conjuction with the access port?
3. Are there any cobb tuners in Houston that can tune the access port for our car?
4. Why have some people gotten CEL's after installing the accessport?

1. No you cannot. The maps on the Accessport have a set boost pressure, and without getting a new map, you cannot change it.
2. You could use a boost controller, but it's extremely discouraged, and unsafe.
3. Not yet. Brad at Engine Logics will be able to tune it once the software comes out. I've had a few friends go there, and they weren't exactly happy afterwards. They're all extremely biased towards what they think is the only right way, and if you have a different part, or are using a different technique, they don't like it and bad mouth it.
4. Some people are gettng CEL's because of different reasons, most of them, if not all, are due to problems not associated with the Accessport. Mine installed with no problems whatsoever.

....

Once the Race tuning s/w comes out ($400, anybody's guess as to release date), you will be able adjust a number of parameters within limits. Unless, they said otherwise, I imagine boost will be adjustable, at least as a percentage of a given value in a map. The changes made with Race s/w stay until the next ECU reset.

Another COBB AP question

If the original "stock map" was saved to the AP, and the car's ECU was then flashed to stage 1+, then could the ECU be flashed to the stage 2+ without unmarrying the AP (will the "stock map" be lost when directly switching from Stage 1+ to Stage 2+.

I understand that COBB is still working on "real time" map switching for the MS3, but I'm not quite sure what that means (capable of having multiple maps stored on the ECU with the ability to change on the fly?)

With the first version release of the accessport, every time you change the map, it counts as a flash.
The real time map swithcing is where you can change between maps without having to flash. I believe the only time you'll have to flash it is pretty much from having the accessport installed, and having it uninstalled, but I may be a little wrong about that.
