Since there are tons of threads often about similar questions about the Accessport and ECUTek reflash technologies, we need a simple place to answer the most common questions. Look below for answer to some of our most frequently asked questions about both of the products, starting with the most recent.
Questions can be added below, the question and a suitable answer will be answered by either a moderator or another member and the thread will be edited to keep things as clean and concise as possible.
Jedimaster's Accessport Walkthrough
What is required for Cobb Stage 2 level?
It is highly recommended that you use a full turbo-back, but a downpipe alone is where most gains by themselves are made and essentially any aftermarket downpipe that tapers to 2.5 or 3" (most are 3" exit), and can use the existing center pipe if needed. You can use any brand of exhaust products, you don't have to use Cobb brand products. Also, any up-pipe can be used with the Stage 2 mapping, the majority of benefits however will be presented in the form of turbo response over much in power advantages. For info on turbo exhausts, consult the TECH REFERENCE
Breaking in your Accessport
You shouldn't have to wait to put the Accessport on your car. As long as your car is broken in from factory break-in specs, you should be able to upload maps right away. The ECU will learn and adapt to your driving style.
Sharing your Accessport
Q. Will my AccessPORT work on multiple vehicles?
A. Yes and No. When you first initialize the AccessPORT for use on your vehicle, it will marry itself to that ECU. From that point on, it will only work on that vehicle's ECU. If you wish to use it on another compatible vehicle, you much first uninstall the AccessPORT from the original vehicle. When you purchase the AccessPORT, you are purchasing one (1) AccessECU reflash license. Thus, that license can only be used on one vehicle at a time.
Adding modifications beyond recommended parts per Accessport Stage maps...
There is a reason why Cobb recommends certain parts for certain stages. They only recommend exhaust component changes for Stage 2 (no recommended changes for Stage 1), and I believe the only parts additional to a Turbo-Back Exhaust that won't effect the tuning is an Up-Pipe with sports cat or catless and a lightened or underdriven crank pulleys.
What is the difference between a Real-Time Map and a Base Map?
If you disconnect the batt you will lose the R-T map and it will default to the base. ...Trey stated there are minor changes to the basemaps not found in the RT. So you may not be taking full advantage of the AP by only using the RT maps. (BoxerGT2.5)
Is the resistor mod needed for deleting cats?
Well, found a new issue, and talked to Perrin and Cobb about it today. It turns out that if you are going to run a turbo back exhaust system, and you have done the up-pipe on our Legacy's, that you do the 2.2K resistor mod to the up-pipe instead of leaving the EGT sensor in.
While attempting to use my cruise control, like clockwork at 15 minutes the check engine light would come on, and the cruise control light would flash and not turn off. The car gave a P0546 cel for the EGT reading being to low temperature. It turns out without any cats or reduced cats in the system, that the exhaust temperatures run much lower in the vehicle, and this throws the cell. Now for some reason it only happens when the cruise control is on.
I have done the resistor mod and now my cruise control works fine. And Cobb tuning stated that they will have that Cell turned off in future maps. This also is a very common problem with WRX and STI owners from reading other reviews on nosaic and what not. (hodgeee)
