    Cobb AccessPort - base map vs. realtime map

    I'm waiting for delivery of my AP for my '04 WRX I'm a bit confused about the whole flashing thing: can I keep my stock ECU with the stock mapping alone and run the realtime map (say Stage 1) and get the results? Or do I have to reflash the ECU's base map and replace it with Cobb's Stage 1? If I can keep the stock ECU and map, I can remove the AP and no one would be the wiser to know it was there, right?

    when you first get the AP you have to reflash it with the ap. then you can load the stock map on if you want and run real time maps later on.

    i just flashed the stage 1 with 91 oct, and run real time 93 oct. but there is a noticable diffrence between the two so i think i am going to load the 93 base map on there instead, the ap can get in the way of driving sometimes.

    If you want the CEL removal feature of the AP, you'll have to flash your base map with StageII, as it's the only one (that I'm aware of) that removes cat and EGT CEL's. Then, you can use whatever realtime map you want.

    It really doesn't matter though... You can use whatever maps in whatever order you wish!
